The electronization, intelligent, networked of the car is the important sign of Hyundai Motor’s development, as consumers change the electronic system, the electronic industry of the global car faces the opportunity that grows at top speed at present. Abroad, the electronic system has already accounted for 30 of the total cost of an ordinary car, the proportion is higher on the limousine, in China, the disposition of the electronic device of middle-and-high-ranking car has already been close to or reach the foreign car industrially developed country’s level. But still there is disparity greatly with foreign countries generally in the Chinese car electron industry, need to devote more efforts to studying and is invested. The electronic technology of the car undergoes two stages of development, is at the third stage now. The electronic apparatus of car of the first stage mainly adopts the discrete electronic element and makes up the electronic controller, and begin to carry out the transition to the integrated circuit products from the discrete electronic element products; The second stage mainly adopts integrated circuit and 8 microprocessors to develop the specialized independent control system of the car; The third stage began with the 1990s, the car electron had an extensive equipment and adopted 16 or 32 microprocessors to control, control technology develops towards intelligent, networked direction. A lot new technological research fields and research focuses have appeared at this stage.

1.The line accuses of technological DBW

Various control systems of the car are developing towards electronization, automatic direction, in the next 5- 10 years, the traditional mechanical control system of car will be turned into the electric system that links with high-performance CPU through the fault-tolerant communication bus of high speed. If car realize line accuse of drive, line control move and line accuse of throttle and line accuse of, hang shelf,etc. by electric motor and automatically controlled signal, adopt these lines to accuse of system’s totally replacing hydraulic pressure and machinery in the existing system to control. DBW adopted on Accord V6 car of new generation is one of the new technologies. DBW is the English abbreviation that the thread accused of the throttle, can also call it the automatically controlled throttle, the throttle of the engine is controlled through the electron. The traditional throttle control method is a driver, through stepping on the gas pedal, is directlied control and launches the switching intensity of the engine oil door by the throttle guy cable, thus determine to accelerate or moderate, was applied to get in touch through the machinery of the guy cable between the driver’s movement and throttle movement. And DBW contacts this kind of machinery to change into an electron to get in touch. The driver still controls the guy cable through stepping on the gas pedal. But the guy cable is not connected to the throttle directly, but is connecting with a gas pedal position sensor, the sensor turns the position change of the guy cable into the electric signal to convey to the brain ECU electronic controller of the car ,ECU sends the relevant sensor signal collected to the order and does the moving device and controls the module to the throttle after processing, the throttle does the moving device and controls the module to send signal to the throttle and do the moving device again, thus control the switching intensity of the throttle. That is to say that gets in touch through the electric signal of the electronic element between the driver’s movements and the movements of the throttle. Though by the look of structure, DBW is more complicated than the traditional throttle control method, but the control of the throttle is more accurate than the traditional way, the engine can be according to various information of going of the car, it is angry to regulate the fuel air which enters the cylinders and mix accurately, improve the burning state of the engine, thus has improved power and economy of the car greatly. The advantage of using the line to accuse of technology is numerous, for example use the line to controlled and moved and does not need to apply the brake the liquid, protect the ecology, reduce and safeguard; Quality is light; Performance is high apply the brake and respond to fast ; Rub minimum more even to the application of force of tire to apply the brake ; Install and test simpler and swifter module structure ; Firmer electronic interface; There is no mechanical connection among the baffles; The simple arrangement can increase the electron and control the function; The footboard characteristic is unanimous; Less,etc. than the hydraulic and systematic component.

2.CAN bus network

As application of automatically controlled units in the car being more and more, the data communication among the car-mounted electronic apparatuses becomes more and more important, is very necessary that the structure car car states the electronic network system based on the distributed control system. The fast exchange, high dependability and low price of a large number of data are the requirements for electronic network system of the car. In this network system, every processor runs independently, control and improve the performance in a certain respect of the car, offer data service when other processors need at the same time. The composition of the network mainly depends on the bus transmission technology within the car. The car bus transmits to link various automatically controlled units, intelligence sensors, intelligent instruments,etc. in the car through a certain communication agreement, thus the network within the car that forms. Its advantage is as follows, have reduced the quantity of bunch of line and volume of bunch of line, has improved dependability and maintainability of the electronic system; Adopt the common sensor, achieve the goal that the data share; Having improved the systematic flexibility, namely pass the change of the systematic all right implementation system function of software. CAN the intersection of Germany and rich generation Company in a kind of serial data communication agreement that the beginning of the eighties of the 20th century develop in bus. Its short frame data structure, non- destructive bus arbitrate technology and flexible communication way, make CAN bus have very high dependability and anti-interference, have met the requirements for real-time character and dependability of the bus of the car. At present, the foreign car bus technology has been already very ripe, and already popularized and applied on the car. The Audi A6 style that China introduced technology and produced has already adopted the bus to substitute original wired bunch since 2000, Passat B5, Bora, Polo, group of Fiat set up the intersection of, the west and that, use CAN bus technology in various degree by the intersection of Harbin Aircraft Manufacturing Corporation and the intersection of horse-racing,etc. and style. In addition, some top-grade passenger train, engineering machinery begin to employ the bus technology. It is estimated 63 that CAN will occupy the markets of whole car procotol by 2005. In Europe, the network based on CAN has occupied the market of about 88 too. Cars using CAN bus network at present mostly have two or more than two buses, one is a motive force CAN bus, mainly include the engine, ABS and three nodes of automatic gear box, the communication speed is generally 500kbps; Another one is a comfortable CAN bus, mainly include the central controller and four pieces of door module, the communication speed is generally 62.55kbps or 100kbps.

3.Car cruise control system CCS

The control system is that can be at the request of driver that the car does not step on the accelerator pedal in operation that the car cruises, keep certain driving speed automatically, lighten the driver’s labour intensity, improve the going automatically and fitting of the car comfortableness. The car cruises the control system is abbreviated as CCS. Also called according to its characteristic ” Car cruise control system ” , ” control system of the constant speed ” , ” control system of the speed ” , or ” control system of cruising ” When. At present, many vehicles especially limousines have already regarded the control system of cruising as attaching troops to a unit the apparatus or apolegamy apparatus. For example imperial crown, Ling Zhi, good and American of Japan, Benz, BMW of Buick, Cadillac, Germany of U.S.A. wait for bus and is equipped with the control system of cruising. After the car installs the control system of cruising, when the speed is in above 40min/h, this device can keep going according to driver’s required speed automatically, and keep this invariable speed, drivers needn’t step on the accelerator pedal. After adopting this kind of device, when driving a vehicle on the expressway for a long time, can make the driver step on the foot of the accelerator pedal and have a rest, it is unlikely to produce fatigue because of controlling the stable speed of the accelerator pedal by car for a long time, the operation of lightening the driver is born. Because electronic system can control operating mode of vehicle accurately, thus make high-speed vehicle that go safe steady reducing by oil consumption, have improved the fuel economy of the car and comfortableness driven. This function is especially suitable for the vehicle going on the expressway. The control system of cruising if uses on the car fitted with automatic gear box, can give play to its advantage even more. The major advantage of the control system is that the car cruises: 1Keep speed to be steady, no matter because wind-force and the intersection of road and slope cause car go what a change it will be resistance, so long as in the engine power allows the range, the travel speed of the car can maitain unchanged. 2The comfortableness of improving the car while going, especially the car goes on the countryside or expressway, comfortableness is more obvious in embodiment. The driver does not need to frequently step on the accelerator pedal by stepping on, so fatigue strength is lightened greatly. 3It is economic and environmental protection to improve, under the same condition of going, for an experienced driver, can save the fuel 15. After using the speed stabilizer in the control system of going the rounds, can in the best cooperation between supply and power of the fuel of engine, lower the intersection of fuel and specific consumption, reduce harmful gas composition rank angry, greatly. 4Lengthen the engine life-span, can make the car work within the range of the engine favorable rotational speed, make to offer oil and among the the intersection of engine and power in cooperating with best state car. The car cruised the development of control system had already had a history of more than 30 years so far, have gone through mechanical control, transistor controlling, analog computer to control and control 4 stages with the digital computer. Japanese Toyota Company begins to install the system of cruising that controlled on the car with machinery from 1965, later Germany VDO Company developed and gave vent to anger to move the machinery type control system of cruising too. German Benz Co. developed the system of cruising that the transistor was controlled, and installed and used on Moakley’s car in 1968.

4.Car navigation system GPS

GPS is a global positioning system, and the third spaceflight project following Apollo’s airship and space shuttle in U.S.A.. It is only used in the military affairs respect at the beginning, but with the development of electronic technology, GPS applies to car’s navigating gradually. The car equipped with navigation system, there is a display screen in the driver’s cabin. Reveal the traffic pictures called the electronic map of a certain city above ,And the position which the car lived in in the picture at that time. If the driver imports to names of the destination, position in the picture, will reveal one from present position of car to destination best route and travel direction pursue, lead the car to go, play a role in navigating. In this way, drivers can reach the strange area by car comfortably and in the safe driving at night. In addition, GPS can also tell the driver the traffic at that time at any time, points out the traffic jam somewhere, somewhere car smooth and coherent, and nowhere has vacant positions that may park. Enable driver to wind the crowded highway section, reach the destination comparatively fast, avoid the traffic jam, raise the efficiency of driving a vehicle synthetically. The whole navigation system is navigated, contained navigating, matching device of the map, signal by oneself to handle several parts such as the unit, storing device, display, sensor to make up by GPS. GPS navigates and is made up of GPS aerial and GPS receiver. GPS satellite launches the electric wave out and launches moment information, and the moment when the receiver can be reached according to the electric wave, calculate the time that the electric wave walks. Multiplying this time by the spread speed of the electric wave can know satellites and distance of the receiver, namely the satellite and distance equipped with car of this receiver. Meanwhile, the orbit position of every GPS satellite is launched out too. So, the acceptance point seat can be asked out by the point of intersect of three spheres taking three satellites as the centre, can confirm this car of seats in the electronic map. When the car goes in tunnel, intensive forest, high-story buildings,etc. underground not to receive GPS signal, the car will contain by oneself and navigate. Go begin, setting up an initial value by driver to the intersection of vehicle and position first. In not going, measure every through to go distance and travel direction certain time, thus position vehicle. Go from obtain by sensor by speed among them, and direction signal is measured by the sensor of the light-transmitting fibre. GPS has navigated and could demonstrate in the electronic map accurately since the car state of navigating in law and getting and some signals of the position should be dealt with through the matching device of the map Come. The electronic map is made like this: Utilize the overall picture photo that aerial survey of the city takes at first, form an accurate topographic map through real investigation, mark and supplementarily, it includes road traffic picture, network of highways and name of the place along the line of every city. Then send the topographic map into the PC, and carry on the data and gather and deal with the editor with the special software through digitized appearance, scanner, produce the digital topographical model. Superpose and then, classification, mark form an electronic map and make read-only optical disc. The development of the car navigation system is very fast, have already adopted 32′s CPU to imbed the little treatment unit of the real-time operation on some systems at present, benefit the high-speed car that goes and deal with the data fast. The application of laser technology, producing high-capacity digitization may store more information depending on one. It make the picture clearers to use the active liquid crystal display of the transistor of the membrane. The car navigation system can offer one’s own position and coordinate, distance of straight line, time, speed, direction,etc. to all go of purpose position in real time. As meeting situations such as road block, construction of highway section or taking a wrong way,etc., GPS can carry on search in time, offer the new route. In addition, for the road surface situation while letting the driver understand that go in advance, GPS still can carry on voice prompt. If network car navigation system and other departments, the driver can obtain the latest information of traffic at any time, thus make the car avoid blocking realizing with the crowded highway section the automatic road is chosen and not stopped going. The popularization use that the car navigated, will bring the new appearance to city traffic in the 21st century.

5.The car electricity controls and moves the system EBS

The car electricity controls the brake through the way that the electron is controlled to replace traditional mechanical drive on the basis of ABS to controls and moves the system EBS, in order to reach the good result of applying the brake, the security that increase the car and apply the brake. When car apply the brake, wheel make power and ground adhere to coefficient to be relevant, in, slip half when roll the state by half as wheel, the ground can reach to adhere to the coefficient biggest, namely can reach greater to make motive force, the edgewise stability at this moment is better too. Not when it has not extremely rolled that the wheel is totally embraced, adhesion drops to some extent on the ground, but edgewise stability is zero. It is extremely apt to appear in the side to slip and get rid of the end phenomenon, it is apt to cause the accident. ABS defend, embrace brake to when the car applies the brake, make wheel in, embrace, fail, embrace state extremely totally again very much soon all the time very much. Namely guarantee the car obtains the greatest adhesion, while can keep corresponding edgewise stability, solve it in the regular system completely, or not enough that the wheel has not cherished and extremely made motive force, or totally embrace it, make the car lose the question of horizontal stability. When the car applies the brake, ABS system is measuring the rotation of the wheel constantly. When the wheel will embrace death, ABS system will send a signal to give to the pressure regulator, in order to control making power of the brake, make the motive force of system stop increasing. A small amount of reflux of liquid reduces pressure to apply the brake in the brake at this moment, then pressurize again, make motive force to increase, reach the best result of applying the brake so for the severalth time in succession, can reach for 10- 20 times / second. EBS system has increased various sensors than ABS system, including three-dimensional strength sensor, brake friction disc abrade the sensor etc.. Apply the brake, brake pedal the intersection of position and signal spread give automatically controlled unit, every strength sensor apply the brake the load, ground adhesion the atmospheric pressure signal is spread to the automatically controlled unit at the same time, regulated the pressure and applies the brake automatically by the automatically controlled unit, form and close the ring to control. This system controls and replaces mechanical drive electronically, while reducing the lagging of mechanical drive of the brake, shorten the braking distance, in the low intensity, make the friction disc abrade minimumly; At the time of the medium-sized intensity, utilize ABS to achieve the best road and adhere to the utilization ratio of the coefficient; At the time of the high strength, exert the pressure of largest applying the brake, thus obtain the best control and make motive force. Rub and abrade the friction situation that the sensor can be monitored so as to each apply the brake scene, control every brake pressure to assign and lengthen service life. EBS system can be carried on by a automatically controlled unit together with other electronic control systems centralizedly and controlled in unison. Realize all kinds of control functions required.

6.The passenger perceives the system OPDS

The 7th generation of Accord V6 car of Honda has equipped front-seat side gasbag, so has allocated passengers to perceive the system in the front-seat passenger’s seat accordingly. Passenger it perceives function of system to be that arrange at the seat sitting when child or the intersection of child and the intersection of side and hair doze off at present, passenger’s seat side gasbag will be closed automatically, the injury to children of the air bag when thus will reduce the side and knock into the accident happens. Then how does the air bag know all these? Hid 7 sensors in the seat of passenger that seemed to be as ordinary seat originally, 6 sensors in the seat back are responsible for observing the passenger’s height of position of sitting, to judge what sat an children or adult, or other things such as beverage bottle,etc.; A sensor by the side of back specially checks whether children are inclining the head and dozing off, whether judge children’s head in the range that the side gasbag launches. OPDS sensor makes these ones that judge according to the passenger’s conductive dimension, the seat has already presumed the conductive dimension of a seat before dispatching from the factory, after the seat was installed on the car and people sat, OPDS system detects a total conductive dimension, the conductive dimension that total conductive dimension deducts the seat is the passenger’s conductive dimension, if passenger’s conductive dimension is less than the judgement critical value that the system presumes initially, then OPDS system thinks what sat is the head of the children or children in the range that the side gasbag ignites, thus close the air bag, ” SIDEAIRBAGOFF ” on the instrument board at the same time automatically Yellow indicator lamp lights up, tells driver that the side air bag has already been closed. Have one showed the utmost solicitude such as the OPDS ” The watcher ” ,Children can enjoy one’s own dreamland during the journey heartily.

7.Move the multimedia system

Use and move multimedia technology and develop the amusement system of the car, this kind of stereo –Picture technology including full-color screen, apparatus of the game, DVD machine, video cassette recorder, DVD machine and puts the phonograph etc.. Moving multimedia technology still embodies in respects such as wireless products, long-range communication apparatus and information processing products,etc. intelligently, include offering the speech recognition system, support many kinds of languages, make the driver not used in moving and operating the amusement system, thus vacate both hands, control, turn to dish. It still can integrate the function of Internet in the vehicle, makes people examine looking at, receiving and dispatching mails, carrying on the stock exchange on the car in order to surf the Net, adopt at the same time ” Use simultaneously ” Way last consumer can convenient and swift to upgrade by multimedia products of them, enjoy more abundant brand-new service. The outfit of the audio-visual amusement media of the number has already begun the generalization in fact, the Karaoka discs, functions of VCD seeing and hearing on the car belong to this kind of design. Still can even build the compartment into DVD theater where the shadow, sound, sound, mere result are all good. The progress of digital technology, has brought the enormous change to car AV world, the car multimedia of the brand-new concept has already begun to appear. The song the Yue ‘s cooperates with Microsoft, utilize windows operating system, use sound appliances in the car, computer technology, navigation technology and automatic language recognition technology synthetically, develop, have car-mounted computer system by in the world first, push one new stage to car-mounted multimedia technology. It is estimated, the car multimedia combining sound, picture, communication of working together will become reality. At that time, sat in the car, except can enjoy the high-quality stereo and navigation, can also book hotel, restaurant, ticket,etc., it becomes possible too to assist and drive.

8.The electric system voltage is upgraded

The global automaker will jointly make a new standard for the voltage of the electronic system in the future at present, namely 36V/12V one pair of voltage systems will use with 42V voltage system. It is estimated the first uses the car of 42V voltage system to appear in a few years, and one will happen for a long time to the international car industry in subsequent ten years, thorough change. At SAE annual meeting held in Detroit several years ago, there were many discussions about here too, how to go to develop 42V voltage system: The difficulty faced at present is anything: How to solve etc..

The advantage that the natural car voltage upgrades is obvious too. Be able to reduce the intersection of line and bunches of sectional area, reduce electrical machinery outside the volume, can also seize the chance, come on one ” the revolution ” electric apparatus at the car ,For example the machinery type relay ending and using at present, enter the solid switch mode, replace present discrete component,etc. with electronic module. Think, the present limousine uses power of 1- 3 kilowatt according to the trade personage, and the using the power to reach 10- 20 kilowatts of limousine by 2010, if the car performance will be improved, arrangement should increase, only take the voltage and upgrade this road and solve the problem. Can predict, the reform of the electric technology of the car, will inject new vigor into development of car.

14/42V and 42V electric system has already got the extensive approval of the industrial circle of the international car, so, can believe this new electric system of car has entered practical time already in the near future. Because the inherent characteristic of this electric system, the control device combined with little electronic device with the semi-conductive components and parts of power, will win a large amount of application in the new electric system, this will bring greater impact to traditional car electric apparatus, and exert a far-reaching influence on the industrial structure of the car electron, electric apparatus spare part. At present, Chinese relevant trade has already offered due care to new electric system of car, this car of new technologies are entering and studying the starting stage.

ECU ElectronicControlUnit Made up of computer and peripheral circuit. And the computer is the integrated microprocessor CPU on the chip together ,The memory and unit input / outputted the interface. The main part of ECU is a computer, and core one is CPU. ECU will be input into the signal and turned into the digital form, will compare with processing according to the reference data stored, calculate the exporting value, outputting signals drives the circuit to control the servo component of several pieces of regulation by the power again, for example ignition coil and electronic switch,etc.. So, ECU is actually an ” electronic control unit ” ,It drives three parts such as circuit to make up from inputting the circuit, computer and power.

Input the signal that the circuit accepts sensor and other devices input, is filtered and deals with and amplifies the signal, then convert the input level of volt to suring. Send from the sensor to the signal that ECU inputs the circuit and have both analog signal and digital signals, inputting the A/D converter in the electricity can change the analog signal into the digital signal, then transmit to the computer. Computer above-mentioned already pretreated signal make operation and deal with, and will deal with the data and send to and export the circuit. Outputting the circuit will reduce the power amplification of digital information, some as the analog signal, make it drive servo component of regulation accused of to work.

2 gearboxes of control units TCU

The automatic gear box of a lot of cars is controlled of electron now, the automatic gear box is mainly by stepless gear box and gearbox controller TCU ElectronicControlUnit Signal sensor input signal and switch,it become about valve clutch and controls electromagnetic than electrical machinery control, purpose to achieve fluid drive.

The electronic control device of the automatic gear box is input the system, computing system and control signal by the signal and outputted these three parts of system to make up. The system is as follows, that the signal inputs Input speed sensor of the gear box, sensor of output speed of the gear box, sensor of the engine cooling temperature, the position sensor of the door, bent axle speed probe of the engine, sensor of temperature of lubricating oil, signals such as the switch,etc. of applying the brake of solar terms. The process calculate or check tables then export the control signal after these signals are input into TCU, control the electric current of the electromagnetic clutch, the electric current of the electromagnetic clutch depends on the operation state of the car. TCU state of going according to the car drives the electromagnetic clutch to energize the size of electric current or close. When the car speed is slower or stops, TCU does not start the electromagnetic clutch, when it is sure to be worth to reach at the car speed, TCU starts the electromagnetic clutch. It become car gearbox than control finishing for TCU, TCU rotational speed and the intersection of door and the intersection of opening,etc. and the intersection of input signal and parameter control gearbox become, rotate clockwise or overturn and accelerate or moderate regulating the motor solar terms according to the intersection of car and speed, engine. Thus reach the best operation state of the car.

3 is defended to embrace dying the brake ABS

The car applies the brake the anti-lock braking system is abbreviated as ABS AntilockBrakingSystem or Anti-skidBrakingSystem ,Mean that can regulate and make the size of motive force automatically, prevent the wheel from being embraced and died in the course of applying the brake, in order to obtain performance, including the best direction stability, turning to the device of ability and minimum braking distance normally of applying the brake best. It is a component of the car brake. Put, can reduce traffic accident effectively with ABS at car, raise, drive a vehicle security. Tough in the 20th century, ABS had already loaded on the train, was used for preventing it extremely causes some friction that the wheel is embraced when applying the brake, enable wheel and rail damage in early period. The fifties, ABS applying to in wave planes lucky,it used for preventing plane from if you can’t apply the brake, run simply after landinging or before impose, and can shorten the braking distance. ” Use ABS technology to start in the sixties on the car. In 1965, the first sample car equipped with ABS appeared at the car fair of London, but only the defending embracing and fitting of the pure machinery type at this moment. In 1965, Ford Company developed and became famous for ” SM-Track ” by cooperating with KelseyHayes Company Single for passway rear wheel ABS,and put at Thunderbird style in 1969; Chrysler Company develops into 3 passways 4 ABSs by cooperating with Bendix Company- ” Sure-Brake” ,Put on Imperical style in 1971. What they adopted is the latest electronic technology of simulation at that time, but all discrete components, the volume is large, with high costs, there are many troubles, dependability is bad. ABS technology and craft are all very ripe at present, have already applied to car and heavy-duty car extensively. My research about ABS begins with the beginning of the eighties. Have just entered the trial production and loads and test stage now. The unit that China develops ABS mainly has the Second Automobile Factory of China Company, the intersection of Ministry of Communications and the intersection of Chongqing and the intersection of highway and research institute, Chongqing great to fit A, play Co., Ltd., Shaanxi, revitalize flat 514 factory, the intersection of Xi’an and the intersection of highway and the intersection of institute,etc. and unit and department. The Second Automobile Factory of China Company began to study ABS since the beginning of the eighties. It is one of the producers of earlier research ABS, the main goal of research work is to digest and assimilate the products in foreign countries now. Research institutes of Chongqing highways develop two generations of ABS products in succession, ECU of the 1st generation of ABS has adopted z80 chip. The second generation of ABS products are FKx-ACl type. CPU microprocessor in ECU of this device has adopted MCS- 96 series 8098 one-chip computer of U.S.A. 1NTEL Company. Drive the circuit to mainly adopt the power MOSFET.

U.S.A. statistics show, have 40 contingency because car slide cause, brake distance to be too long causing when the brake nearly. Can adopt ABS system the automatic wheel in the course of applying the brake make motive force, prevent the wheel from being embraced in order to make the result of applying the brake best.

4 mixed dynamic automobiles

In 100 years of development of car, it is 100 years when human civilization and economic development are swift and violent. Nowadays, the recoverable amount of the whole world car is up to 6. More than 700 million, the car has already been inseparable from daily life and production. However, it was deficient gradually that numerous fuel cars discharged deterioration and petroleum resources day by day of the air quality caused, make it become the urgent task of industrial circle of the current car to develop the new car of low emission, low oil consumption. People pay more and more attention to the car of other fuel and development of electric automobile. Use the electric automobile ElectricVehicle is abbreviated as EV Can realize pollution-freely, it is not the petroleum resources and can utilize coal, water conservancy,etc. to be other, so, it is undoubtedly the most effective route to solve problem. However, because the question in battery the density of its energy, life-span, price one of the key parts of the electric automobile,etc., make the internal-combustion engine car unable with traditional of cost performance of the electric automobile contend. Though performance and internal-combustion engine car of the electric automobile with advanced international standards are very roughly the same at present, but the too high cost makes it difficult to commercialize. Under this kind of environment, merge the car of the internal-combustion engine and the mixed power electric automobile of the electric automobile advantage HybridElectricVehicle, abbreviated as HEV A dark horse, become the focus that the new car develops worldwide. Can believe, in the energy storage part of the electric automobile – -The battery is not fundamental before break-through, it is that solving blowdown and energy problem had the routes of the realistic meaning to use the mixed motive force electric automobile most.

Mixed motive force electric automobile HEV Allocate electric drive system and auxiliary power unit AuxiliaryPowerUnit on a car at the same time, abbreviated as APU ,Among them APU is the original motive of burning a certain fuel or generating set driven by the original motive, APU is made up of original motive and generator, usually integrates these two parts as an organic whole. The original motive drives the generator to generate electricity, its electric energy is delivered to the motor directly through the controller, emerge to drive the moment to drive the car from the motor. The battery plays a role in equilibrating the output power of original motive and input power of motor in fact: When the power of power generating of the generator is greater than the power that the motor needs until car moderate slide, go or the intersection of person who park and operating mode in short-term at a low speed ,The controller controls the generator to charge to the battery; the operating modes such as car starting, accelerating, going at a high speed, climbing when the power that the generator sends out is lower than the power that the motor needs ,The battery provides the extra electric energy for motor. At present the original motive that HEV adopts or fires the steam turbine generally for diesel engine, petrol machine. Mixed the intersection of power and former motive, motor, energy storage device storage battery electric automobile Put together, the good match and controlling rationally, can give full play to the car of the internal-combustion engine and advantage of the electric automobile between them, avoid their own deficiency, nowadays have low emission and low oil consumption car in the physical development meaning most. The mixed motive force electric automobile which the countries all over the world research and develop has different structure forms at present, it is different to drive systematic disposition and mode of combination according to it, is divided into a tandem, connecting in parallel type and drifting along and uniting the formula 3 kinds of modes of combination. There are close connections in mixed motive force electric automobile and electric electron, its key part of electric system:

Electrical machinery –Generator / motor / starting machine; The electric electron is driven / commutated, includes the sensor and protect the circuit; The direct current presses the changer; Storage battery. The one illustrated in Fig. 2 is the composition block diagram of the electric system material object of one 42V, Fig. 3 is its block diagram of circuit.

The countries all over the world are devoted to developing the advanced mixed motive force electric automobile at present, the 16th Meeting of international electric motor car and the exhibition EVS held in Beijing in 1999- 16Get on, the mixed motive force electric automobile becomes the focus, some exhibits exhibited have represented the current situation of development of mixed dynamic automobile of the world. Mixed the energy car and developed various countries and just started, its development trend was as follows:

It is the major developing direction to mix the energy car serially, the fuel battery car of pure electric motor car will follow

Mix the energy car and develop and spur large quantities of industrial development: The material chemical industry, alloy, steel ,The electron, communication, electrical machinery, the battery, machinery is processed, environmental protection,etc.

The car-mounted voltage will rise to above 42V, but the low-voltage will coexist for quite a while

The belt drives the integrated starter / generator, the bent axle drives the integrated starter / generator and runs side by side and develops

The electrical machinery is designed and develop and go on with the control method synchronously

Mix the development that the energy car will have and will continued promoting the specialized electronic module

Wide speed ratio, high-efficient, dependability is the challenge question that an electric system develops

It is to nowadays solve car energy-conservation and effective way of the blowdown problem to mix the power electric automobile, though mixed motive force electric automobile has not realized no emission, but its achievable power, economy and discharge index are to relieve car demand and environmental pollution and sharp ideal route day by day of shortage contradiction of petroleum. So, we must pay attention to the role in car evolution of electric automobile of mixed motive force, hold the present development opportunity firmly, put into the essential manpower and materials, solve the problem that the mixed motive force electric automobile exists.

Hyundai Motor is closely related to electronic technology especially electric and electronic technology, the content taking one-chip computer as central electronic technology determines the automatic level of the car in certain meaning in the car. The higher the automatic intensity of the car is, the electric electron in the car varies and drives the more systems, it is the more complicated. So vary and drive the quality of the system to influence efficiency and performance of the completed car directly. The auto industry of China has had very great development in recent years, but electronic device especially key electronic device in the car mainly depend on import, develop the high-performance electronic devicing has broad markets.

The importance initiation that the electronic product stressed in the car day by day, to low-cost, high dependability sensor and demand that the transmission device increases day by day. These devices do not exist independently, but must be with the systematic mainly electronic control unit ECU Carry on communication. The device communication of the past sensor / transmission usually adopts the unidirectional analog signal, every long-range apparatus adopts one’s own special line to connect with ECU. Because car environments are full of electric noises, it is very difficult to keep the signal integrality on these circuits, and the dependability of the system will be influenced. Connecting up will bring other problems – -Take up the space, increase the weight and cost and difficult to safeguard. Fortunately the digital many ways reply and solve the above-mentioned problem with communication, this kind of technology can keep developing, still expand the application of the electronic system of the car by high-efficient communication at the same time. Office land Internet LIN The bus framework has already developed into 2.0 edition now, can meet to the sensor / demand for the simple communication scheme of the transmission device, can lower costs and improve stupidly and excellently through standardizing

. The emerging of LIN standard has also catered to the development which mix the semi-conductive technology of signals, they can realize together sensor and transmission device are connected to the single integrated circuit IC All typical functions needed. And, LIN standard with advanced to mix the intersection of signal and craft, bring, introduce low-cost for automaker new electronic system and reduce existing systematic opportunity of cost together also. While bringing high convenience and security to car owner, they can also improve and safeguard performance and dependability.

Retreat and ask second-classly

In the present electronic bus standard of car, LIN can offer the best solution of meeting sensor and transmission device signal transmission demand. Many kinds of exclusive solutions can be modulated PWM through the pulse width Or adjustable pulse width VPW Wait for the simple scheme to carry on the signal digitizedly to transmit. These schemes are all based on various physics layers PHY Design, in these schemes, each of sensors or transmission devices generally needs a communication line, and the sensor generally adopts and exports unidirectionally to the communication of the transmission device to ECU or ECU. So, the framework of these networks can’t realize two-way communication and diagnose, thus limit their use. In addition, because they are exclusive solutions, thus influence the trade to realize large-scale production and design are utilized through implementing the open standard.

The choice of making changes according to specific conditions adopts the ripe communication standard ‘ For instance: Control the LAN CAN Bus Transmit signals between device interface of the sensor / transmission and ECU. However, CAN and similar communication generally need to adopt little controller and auxiliary circuit, need complexity and cost of the range or reasonable range so as to produce and go beyond sensor and transmission device. In addition CAN is also based on the double-line bus, and the best solution only needs to adopt a circuit to realize low-speed, low-cost communication.

Simple open standard

Though LIN initial design object is a car body electron, it has ample scope for abilities in new application too, one of them is the interface of the sensor / transmission. 20.0kbps data speed that LIN2.0 appoints is enough to meet most demands of sensors and transmission devices, and LINPHY and agreement controller can integrate in the mixed signal integrated circuit used for long-range apparatus easily. LIN2.0 norm includes describing the physics storey and agreement on the data chain floor are defined; This norm also includes defining the disposition language of the common interface explains among systematic disposition and network node in addition, it’s time to prove that can also be used as development and analysis tool and imported the materials; Include directing against the application programming interface API of the additional software at the same time Define. Specially employ the standard defined for the car as LIN alliance, this standard realizes jointless development and design tool chain, improve development speed and dependability of the network at the same time.

LIN is single track transmission means, thus can reduce connecting up and line bunch wiringharness The requirement, and then contribute to reducing the weight and saving space and cost. This standard stipulates the single main node has 16 pieces of independence from the node. Communication is touched off on schedule by the main node, so does not need to carry out to arbitrate operating between reporting the apparatuses at the same time. Have from the node from the synchronous characteristic, can adopt RC oscillator on stretch without adopting the crystal or ceramic resonator, thus lower costs by a wide margin. LIN agreement can guarantee to prolong when signal transmission, the predictability of the implementation system – -This is a key element of most sensors / transmission device signals. The agreement is extremely simple, can string the mouth UART/SCI together through being asynchronous Operation. So, it is very low to implement the cost the chip, make LIN become and mix the excellent bus solution of the signal technology – -And the technology use mainly for, produce the intersection of car and sensor and the intersection of transmission and signal that device adopt, regulate and export IC.

Realize that mix the signal craft

LIN standard is the important progress of device communication of the car sensor / transmission, but, with mixing the newest development of the semi-conductive craft of signal to merge, its importance is reflected even more outstandingly. Now, because be able to fully utilize one’s own professional technique in CMOS digital craft and advanced simulation craft two at a high speed, it is still the square system integration level of the pool at night of it that IC manufacturers can realize several years ago. Suitable for the car sensors / models employed in transmission advancedly and mix the signal craft to include: Linear Bi-CMOS LBC , high-pressure CMOS, and insulating silicon SoI Craft. A lot of above-mentioned crafts can be realized on single one of the whole sensor / transmission device electron systematically SoC Implement, include power, high pressure, digital logic, stores and high-accuracy simulation function.

If need to be intelligent on the chip, the advanced mixed signal craft allows to integrate the digital logic of the rational level except LIN agreement controller. For example, may include reporting the logic device of the sensor or transmission device state to design, in order to be make can can be used in safeguarding be used in the database development of dependability all one’s life in time as well as to diagnose the function. Mix future generation signal technology allow what knock to raise magnesium Shen bits τ of river cliff 1 chirps pregnant in official  s low for the sides of a ship after lasting  extremely controller peptide D Yin δ Kou Xiu  umbrella 4s yellows little #8220; Click the touching type ” Car windowpane going up and down device – -It needs to run one prevent glass from crowding the algorithm which injures the finger while rising. And to the application needing to communicate more complicatedly and more quickly, it still allows the integrated CAN function in mixing the signal device to realize the semi-conductive function integrated in LIN communication.

The sensor / transmission device gives an example

Instrument of Dezhou TI TPIC1021LIN-2.0 transceiver utilize advanced to mix signal technologies integrated last that LIN sensors and transmission device communication compatible to be stupid and excellent and keeping their not low to succeed Originally foundation stone. LBC4 linear Bi-CMOS craft based on TI of this transceiver, adopt the battery voltage work of the car, so does not need external power. Trouble protect function make apparatus can bear LIN at the bus from 40V to voltage of 40V, static discharges ESD on stretch at the same time Protecting the function can be born and up to 17kV ‘ International Electrotechnical Commission With 21kV dummy Peak value voltage. Can integrate and connect the sensor or transmission device to car electric wire netting and more components needed of LIN network on this basis. The function includes on typical slice: The simulation that the front inputs strains the wave function, modulus converter ADC in the car voltage regulator, sensor which meet the systematic requirement are outputted , figure strain the intersection of wave and compatible with control, and LIN agreement controller. 1 Fig. illustrate one one that is on the basis of LBC4, overall integrated sensor interface with examples. High integrated level and circuit that this kind of device has protect the function to make it just suitable for the space and very limited abominable car environment of cost.

And TPIC10271 transmission device interface is that one is based on LBC-4D specially the car employs the device designed. It has integrated the 3.3V voltage regulator / watch-dog which adopts the power of battery, get the intersection of user and high-pressure interface, high side FET used for position sensor or other types sensor of switch ‘ An effect transistor Driver, which is use for the control relay of the motor two low side FET drivers, feedback the operation amplifier, protect the circuit and PHY compatible with LIN ‘ Fig. 2 . Export and connect to the little controller used for controlling the algorithm directly, for instance: The defending crowding and controlling the function wounded of glass going up and down device. The other devices mixed with TPIC1021 and TI in the serial products of signal are the same, TPIC10271 enters the dormancy mode of electricity of province when not working, it is interfered with EME that it is low and electromagnetic With resisting electromagnetically and interfering with ability EMI high .

As to other application, the mixed signal technology can also integrate other functions besides integrating the functional block in the above-mentioned two devices equally, including: The low pressure used for single track and many rails is lowered with the switch voltage voltage stabilizer, different high / low side driver, various operation amplifiers, interface of digital logic device, and LIN,etc. communication interface that disposed. The interface of usable transmission includes: The intersection of H and bridge, suitable for DC paste up / have intellectual driver, and relay driver to brush the motor by the intersection of three-phase and direct current. These drivers are used in electronic seat and rear-view mirror, lock, wind shelf rain brushing and defroster, glass, going up and down device of the aerial, system of heating, ventilating and air-conditioning HVAC , and is used for offering users to various other electronic systems of comfortable and security.

Systematic advantage

And communication interface change compatible with LIN mixed the intersection of signal and IC into can produce many kinds of the intersection of system and magnitudes of advantage sensor / the intersection of transmission and the intersection of device and signal. Raise the stupid stick of system and diagnose the function at first. The circuit quantity can reduce lowering costs and potential trouble source, and because LIN can realize two-way communication, can obtain the diagnostic message from sub apparatus, but can offer trouble information from the apparatus while the systematic problem happens with main apparatus. In addition, LIN has dispelled the requirements for exclusive interface, can already develop assembly and software on the basis of the open, reliable and standard common communication scheme through adopting.

Can construct, take 3 line only with LIN ‘ Battery, earthing and LIN Sensor or transmission device,last bunches of requirement. The device shell is smaller, realize better sensor / transmission device is fixed up, but does not need to consider the question of connecting up too much. LIN and advanced mixed signal craft can reduce the systematic cost in many aspects: The assembly quantity is reduced; The stock is reduced; Compactness, simpler printed circuit board and sensor / transmission device shell; Use on slice the oscillator replace the brilliant shaking or resonator system as the clock source; Higher dependability. Some above-mentioned factors can also reduce weight and space to consume – -Pursuit not changed in the car design all the time.

This kind of progress is only car sensor and the transmission device intelligence and the first step that the function development took. The future generation will integrate the little little controller, can realize programmable function and higher flexibility if the future generation mix the car IC of signals, thus meet the future demand for the car. With the intersection of car and sensor and transmission being intelligent to raise constantly in device, car designer can imagine the intersection of car and intellectual application of system freely.
