摘　　要：提出一种结合横摆力矩控制和主动前轮转向控制的提高紧急制动侧偏稳定性的控制方法.控制器采用前馈-反馈复合控制,通过最优控制算法求解反馈控制参数,并对稳定性控制参数和制动力参数进行优化,以缩短制动距离.仿真对比实验证实这种方法在提高制动稳定性和缩短制动距离方面都有良好的效果.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.

关 键 词：横摆力矩控制 主动前轮转向 侧偏稳定性 最优控制
