摘要
车辆在低附着弯道路面上制动是一种非常危险的工况。本文从车辆在低附着弯道路面上制动整车受力的角度出发,分析了车辆弯道制动时ABS控制的不足,提出了车辆ABS与横摆力矩控制协调控制的制动力控制策略。利用模糊控制原理设计了横摆力矩控制器,在制动车辆ABS的基础上,通过对车辆的横摆力矩控制和车轮滑移率的调节,实现了制动过程中对附加横摆力矩的动态调整,从而可以在不增加硬件成本的条件下实现车辆在低附着弯道路面上制动的稳定控制。最后进行仿真试验验证了该控制方法的有效性。
It is a dangerous condition for a vehicle to brake on low adhesive cornering road. Based on the force bearing condition of the whole vehicle braking on low adhesive cornering road,a braking force control strategy by the integrated control of ABS and yaw moment control for vehicle cornering is presented. Based on vehicle braking with ABS,a yaw moment controller based on fuzzy control theory is designed,by controlling yaw moment of vehicle and regulating slip rate of wheels,the dynamic regulation of yaw moment in vehicle braking is realized,therefore,on the premise of not increasing the cost of hardware,vehicle stability control for cornering braking on low adhesive road is accomplished. Simulation shows the validity of the proposed control method.
