A novel traction control strategy based on slip ratio gradient PID control is proposed. The gradient of slip ratio can be controlled accurately through adapting the driving torque by analyzing the dynamic process of the wheel. The optimal slip ratio for traction control is found through the analysis of the characteristic of the tire. The slip ratio of the driving wheels can be control at the optimal point through slip ratio gradient PID control. An electric vehicle model for simulation based on MATLAB/SIMULINK has been built and simulations have been carried out. A hardware-in-loop test bench has been built and experiment has been carried out. Results show that the strategy can achieve better driving performance than motor torque PID control strategy.
