트레일러를 장착한 차량의 Neutral Sway 감쇠를 위한 Yaw Moment 제에 관한 연구

In this paper, the development of yaw moment control algorithm is studied to reduce neutral sway response of vehicle with trailer. Generally, trailer has been changed the dynamic characteristics of that vehicle. The changed dynamic characteristics affected include rotation about the yaw axes and transitions in the lateral direction. Due to kinematic constraints of trailer with vehicle, the response of vehicle presents unstable and nonlinear characteristics. To improve vehicle stability, the yaw moment controller is proposed in this paper. The 3-DOF vehicle model with trailer is representing to estimate the vehicle characteristics, and the yaw moment controller is implemented using simplified 3-DOF Vehicle model. In this study, the yaw moment controller is proposed to reduce neutral sway response of vehicle with trailer. Due to changing of vehicle dynamic characteristics with the yaw moment controller, it is required to validate the stability of vehicle-trailer through SAE J2664. SAE J2664 is standard test procedure that is proposed evaluation method of natural sway response of a particular trailer. The simulation result shows the response of vehicle-trailer with proposed the yaw moment controller. As conclusion, the yaw moment controller with 3-DOF model is proposed and evaluated through J2664. In addition, the simplified yaw moment controller is proposed for improving vehicle-trailer stability.
