Research and Test on Traction Control System of Distributed Driving Electric Vehicles

The Traction Control System is the foundation to maintain the vehicle tractive performance and stability. In view of the characteristics of distributed driving electric vehicle, a traction control method is designed to control the wheel slip rate by adjusting the motor torque directly. And through reasonable correction to the target wheel speed, a balance of acceleration and stability of automobile can be reached. The results of simulation and real vehicle test show that the control algorithm can achieve the control target of restricting four wheel slip of the vehicle on the uniform, split and opposite adhesion road.
