Advanced traction control technology for vehicle with in-wheel motors

摘要

Based on more quick torque response of direct-driving motor than traditional transmission, the advanced traction control system (TCS) for electric vehicle with motorized wheels is studied to achieve a better traction control performance. PID algorithm was proposed as the method in the TCS control system of EV with in-wheel motors. Simulation models were conducted to test the feasibility and practicability of the PID control method in the TCS system. The controller of this electric vehicle was developed. The better performance of it was validated by the road test of the electric vehicle with inwheel motor too. The results show that the TCS system for electric vehicle with in-wheel motor, controlled by the PID controller can respond quickly and adapt to different driving situations appropriately.
