Active yaw-moment control based on logic threshold and PID control

Active yaw-moment control (AYC) is one of the advanced active safety technology for modern vehicles which method could enhance vehicle active safety. In this paper the control method with combination of logic threshold and PID control is brought out to improve the vehicle stability. The PID control parameters are generated by logic threshold method through the controller adjusting parameters. The wheel brake torque to keep vehicle stable is calculated by PD controller. The results of simulation show that the self-correcting logic threshold and PD control algorithm can be used to control the vehicle performance effectively.
