基于制动轮缸压力的汽车ABS滑移率的计算

Calculation of ABS Slip Rate Based on Brake Pressure of Wheel Cylinder

汽车ABS主要通过调节制动力来控制制动滑移率 ,获得较高的附着利用率 ,达到缩短制动距离 ,并且保持一定方向可操纵性的目的。一般的ABS是通过大量道路试验求得控制参数 ,实现对滑移率的控制。本文提出了基于制动轮缸压力的汽车ABS制动滑移率的计算方法 ,并且经过实验证明了其合理性。

ABS can obtain high usage of adhesion coefficient by adjusting the pressure of wheel cylinder to control the brake slip rate and it can shorten the braking distance and keep the direction controllability. In general, controlling ABS and obtaining the algorithm are based on a lot of road experiments. This paper introduced an algorithm to calculate the ABS slip rate based on the pressure of wheel cylinder and this method was verified by the experiments.
