摘　　要：分析了车辆ABS系统在弯道制动时存在的横向稳定性问题,提出了一种低附着弯道路面车辆制动力控制策略。它综合考虑车轮防抱死与车辆发生侧滑时所能承受的最大侧向力,根据两者所允许的最大制动力中较小值确定施加于车辆的制动力。所进行的数值仿真结果表明该控制方法能提高车辆在低附着弯道路面上的横向稳定性。The problem of vehicle lateral stability during braking on bent road with anti-lock braking system applied is analyzed. Based on this, a vehicle braking force control strategy on low adhesive bent road is proposed, which concurrently considers the maximum lateral force the wheel can take in both wheel lock-up and side slip cases and takes the smaller of two maximum allowable braking forces for both cases as braking force to be applied on vehicle. The results of numerical simulation conducted show that the proposed control scheme can effectively enhance the lateral stability of vehicle on low adhesive bent road.
