摘要
To achieve the differential function of electric vehicle of two wheel-hub motors, by following the optimal slip ratio of each wheel and equalizing the slip ratio of both drive wheels as target, a differential control strategy based on slip ratio is proposed. Using the standard,ti-s curve to set the fuzzy rule, a fuzzy controller is constructed to estimate the adhesion coefficient of pavement and the optimal slip ratio. Then, based on the optimal slip ratio of each wheel, the electronic differential control strategy designed by linear sliding mode is adopted to control the driving torque of the two rear wheels to realize the electronic differential function. The simulation results show that the method proposed in this paper is better to realize the differential function of the vehicle and improve the driving stability of the electric vehicle.
