Abstract: Aiming at the problem that recently both the driving strategy for the motor in wheel and steering strategy for the electric vehicle were researched independently, the structure, the control system, the motor in wheel driving control system, the independent steering system, the CAN communication network and the power tube isolation drive were studied, and the integrated controller for the electric vehicle was proposed. Experiments on 5 kinds of vehicle working mode were carried out based on the integrated steering controller driver. The steering and electronic differential control of the normal working mode was focused by experiment. The results indicate that the integrated controller can meet the real time, accuracy and reliability requirements of the electric vehicle.

Key words: electric vehicle(EV); drive control; control by wire
