摘要：
Steering-by-wire is different from traditional mechanical steering. It cancels the mechanical connection between the steering wheel and the steering mechanism and can be used to freely design the transmission ratio. This paper uses CarSim and Simulink co-simulation to establish a vehicle model with steer-by-wire based on the yaw angle gain. The ideal transmission ratio is designed with constant weight and constant lateral acceleration gain. The fuzzy control design is adopted at high speed, and the sliding mode control algorithm of active steering is designed based on the ideal transmission ratio. Finally, it is verified by simulation experiments that the vehicle stability and handling after variable transmission ratio are better than traditional mechanical steering, which effectively reduces the operating burden of the driver.
