摘 要：Aiming at the steer-by-wire control system of in-wheel motor electric vehicle.A control strategy of steer-by-wire system is proposed for *** the steering wheel angle and the velocity as input,and establishing the output torque distribution coefficient of fuzzy control rule *** order to improve the steering stability and sensitivity,The difference between ideal and actual yaw rate is introduced,and the dynamic correction coefficient is obtained by establishing fuzzy controller combine with torque distribution *** simulation and experiment test results show that the control strategy based on yaw rate difference optimization can ensure the stability of vehicle steering and And improve the sensitivity of *** effectively avoids the side slip and tail off dangerous conditions when steering.
