摘要: 提出一種結合橫擺力矩控制和主動前輪轉向控制的提高緊急制動側偏穩定性的控制方法.控制器采用前饋-反饋復合控制,通過最優控制算法求解反饋控制參數,并對穩定性控制參數和制動力參數進行優化,以縮短制動距離.仿真對比實驗證實這種方法在提高制動穩定性和縮短制動距離方面都有良好的效果.Abstract: A control system was proposed to improve braking distance and stability by the integrated control of yaw-moment control and active front steering. A compound controller with forward and feedback controllers was presented, and the parameters of the feedback controller were obtained by the optimum control theory. Then the output parameters of the controller and braking forces were regulated in order to shorten braking distance. The control method was verified by simulation that stability and braking distance are optimized.
