摘　　要：在多体动力学软件ADAMS环境下建立了某微型车的动力学整车模型以及道路模型,用step函数描述制动力矩,用制动力矩的时间历程来映射驾驶员的意识状态,并进行了制动工况的虚拟试验仿真。以汽车的动力学响应为依据,定量的分析了驾驶员的制动行为对汽车制动安全性的影响:驾驶员的制动踏板力等于某一中间值时,汽车的制动方向稳定性对其最为敏感;而驾驶员踩下制动踏板的动作时间对汽车的制动方向稳定性几乎没有影响。In this paper, with the help of ADAMS/View, a multi - body dynamic model of a micro - vehicle with a typical configuration, a road model and vehicle - road coupling model was established. The step function was selected to descript braking moment, and using the history process of the braking moment to reflect the consciousness of drivers＇ response. Virtual test of braking was carried out. Influence of driver＇ driving behavior on braking security based on the dynamics respond was analyzed quantitatively, thus, some conclusions were get as following： as force action on pedal within a midterm range, direction stability of braking condition was sensitive most to the change of braking force; duration of braking presented no obvious effect on direction stability of braking.
