Key words: electric vehicle tec
2、hnology； energy crisis； Intelligent electronic technology； Development prospect As the world energy crisis, and the war and the energy consumption of oil - and are full of energy, in one day, someday it will disappear without a trace. Oil is not in resources. So in oil consumption must be clean befo
3、re finding a replacement. With the development of science and technology the progress of the society, people invented the electric car. Electric cars will become the most ideal of transportation. First, the chapter of electric vehicle development 1, development of electronic control technology In th
4、e development of world each aspect is fruitful, especially with the automobile electronic technology and computer and rapid development of the information age. The electronic control technology in the car on a wide range of applications, the application of the electronic device, cars, and electronic
5、 technology not only to improve and enhance the quality and the traditional automobile electrical performance, but also improve the automobile fuel economy, performance, reliability and emissions purification. Widely used in automobile electronic products not only reduces the cost and reduce the com
6、plexity of the maintenance. From the fuel injection engine ignition devices, air control and emission control and fault diagnosis to the body auxiliary devices are generally used in electronic control technology, auto development mainly electromechanical integration. Widely used in automotive electr
7、onic control ignition system mainly electronic control fuel injection system, electronic control ignition system, electronic control automatic transmission, electronic control (ABS/ASR) control system, electronic control suspension system, electronic control power steering system, vehicle dynamic co
8、ntrol system, the airbag systems, active belt system, electronic control system and the automatic air-conditioning and GPS navigation system etc. With the system response, the use 2 function of quick car, high reliability, guarantees of engine power and reduce fuel consumption and emission regulatio
9、ns meet standards. 2, The modern development of automobile The car is essential to modern traffic tools. And electric cars bring us infinite joy will give us the physical and mental relaxation. Take for example, automatic transmission in road, can not on the clutch, can achieve automatic shift and e
10、ngine flameout, not so effective improve the driving convenience lighten the fatigue strength. Automatic transmission consists mainly of hydraulic torque converter, gear transmission, pump, hydraulic control system, electronic control system and oil cooling system, etc. The electronic control of sus
11、pension is mainly used to cushion the impact of the body and the road to reduce vibration that car getting smooth-going and stability. When the vehicle in the car when the road uneven road can according to automatically adjust the height. When the car ratio of height, low set to gas or oil cylinder
12、filling or oil. If is opposite, gas or diarrhea. To ensure and improve the level of driving cars driving stability. Variable force power steering system can significantly change the driver for the work efficiency and the state, so widely used in electric cars. VDC to vehicle performance has importan
13、t function it can according to the need of active braking to change the wheels of the car, car motions of state and optimum control performance, and increased automobile adhesion, controlling and stability. Besides these, appear beyond 4WS 4WD electric cars can greatly improve the performance of the
14、 value and ascending simultaneously. ABS braking distance is reduced and can keep turning skills effectively improve the stability of the directions simultaneously reduce tyre wear. The airbag appear in large programs protected the driver and passengers safety, and greatly reduce automobile in colli
15、sion of drivers and passengers in the buffer, to protect the safety of life. The second chapter electric cars on the environment influence and electronic technology: 1, reduce pollution: of course battery electric vehicle is the key, the electric car battery mainly has: the use of lead-acid batteries, nickel cadmium battery, the battery, sodium sulfide sodium sulfide lithium battery, the battery, the battery, the flywheel
