摘　　要：分析了路面不平对牵引力控制系统的影响,提出了基于车轮加速度的路面识别方法,在此基础上提出了考虑路面不平度的牵引力控制算法。应用MATLAB建立了仿真模型,通过对不平路面的牵引力控制算法进行的仿真结果表明,考虑路面不平的牵引力控制系统能够识别路面不平,并能有效控制驱动轮的过度滑转。The influence of the road surface roughness on the traction control system was analyzed, and the method of the road surface roughness recognition based on the wheel acceleration was presented. Then, the algorithm of traction control system with the consideration of the road surface roughness was proposed. The simulation model was built with MATLAB, and some simulations with vehicle running on the rough road were performed. The simulation results show that the traction control system with consideration of the road surface roughness can recognize the road surface roughness and control the over-spin of the driving wheel effectively.
