Research on Control Strategy of Two Independent Rear Wheels Drive Electric Vehicle

The 4 DOFS dynamic simulation model of two independent rear wheels drive electric vehicle was built by the Matlab/Simulink software. Asynchronous motors were used in the drive wheels .The motor vector control algorithm and the slip ratio differential control strategy are put forward in this paper. Simulation results showed that dynamic control of motor torque could be achieved with the vector control system and good steering stability of electric vehicle could be realized with differential algorithm.
