This article establishes a dynamics model with the nonlinear three-degree freedom for the steering-by-wire system vehicle with the lateral disturbances and studies the influence of the lateral disturbances on the vehicle operating stability.Also it analyzes the control effects of the lateral stability by using the PID control and the active control of the steering motor by using the fuzzy PID control.The results show that the fuzzy PID control can adjust the real-time PID control parameters and effectively improve the vehicle lateral stability under various lateral disturbances.
