摘要
In order to eliminate excessive slip phenomenon of driving wheels during the driving process for distributed driving electric vehicle, an acceleration slip regulation strategy is analyzed and proposed.Based on Burckhardt tire model, a real-time road estimator is designed, which can obtain the current road attachment coefficient and the optimum slip rate.The torque fuzzy controller is designed, which can adjust the driving torque of each driving wheel.Then it comes to a better realization of the vehicle slip rate accurate control, and the slip rate of each driving wheel can be change within the optimum slip rate range.Study results indicate that the acceleration slip regulation strategy is an effective way to improve the dynamic performance and stability of the distributed driving electric vehicle in this paper.
