Abstract

A new traction control which utilizes the maximum transmissible torque estimation (MTTE) scheme to execute the anti-slip control of electric vehicles is proposed in this study. Since the function of embedded knowledge mechanism, the chassis velocity and information about tire-road conditions is unnecessary. A closed-loop observer with disturbance estimation performance is employed to enhance the steering stability of MTTE approach. The proposed scheme which contains the closed-loop friction torque estimator is not required to fulfill any differentiator. Moreover, the inversion of the controlled plant is also unnecessary. Evaluation examples are given to illustrate the performance and feasibility of the presented anti-slip strategy.
