| 摘 要： | 为了解决车辆在低附着弯道路面制动中载荷转移造成的汽车失稳问题,建立7自由度整车模型。通过分析整车弯道制动过程的动态特性,推导出制动力与滑移率的关系,提出了纠正转向中车辆失稳的措施,设计了以滑移率为主的门限值控制方法。仿真验证了该方法能够有效提高制动稳定性。

| Abstract: | In order to solve the impact of wheel vertical load transfer,a dynamic model of 7 degrees freedom for an entire vehicle when curved braking on low adhesive road is established.The dynamics are analyzed and the relations between braking force and slip are derived.The measure of mending vehicle’s instability is proposed.The control strategy mainly based on the slip ratio threshold is designed.Simulation is done which verify the method is effective in improving the braking stability. |
