ABSTRACT

Electric vehicle is an important branch of the development of automobile industry, the core technology includes vehicle engineering, motor and drive technology, battery technology, control technology. With the energy crisis looming, the development prospects of electric vehicle unique, attracted to promote large-scale research institutions at home and abroad, has become a hot research, and has made various achievements.

The wheel drive electric vehicle is a new electric vehicle (Electric vehicle, referred to as EV) the direction of development, with the development of electric vehicles and the process of industrialization, the electric car with its ideal control performance and wide application prospect, and has caused widespread concern in the academic and engineering circles. The two were studied, analysis, and experimental design related to drive control system of electric vehicle.

First of all, electric cars, the domestic and foreign development background in detail, introduces the classification and comparison of driving system.

Secondly, the differential control algorithm from the traditional electronic, the project by the wheel has the advantages of simple and novel drive electric vehicle as the background of the advantages, by optimizing the design and control of the dynamic performance of the system, in-depth vehicle speed control advanced vehicle control strategy research, chip wheel drive electric vehicle based on the design, and around this idea, the hardware circuit design.

Finally, this paper final analysis of the input parameters, according to the measured waveform, verified the feasibility of electric automobile electronic differential control scheme.

Key words: electric vehicle, differential control, torque distribution, vehicle dynamic model.
