基于积分滑模的电子机械制动系统ABS控制
ABS Control of Electronic Mechanical Braking System Based on Integral Sliding Mode
摘要
Abstract
In order to solve the disadvantages of traditional brake system logic threshold control,which was compli-cated in logic and difficult to make full use of road adhesion,and the problems of nonlinearity and uncertainty of ABS,a control strategy of ABS based on road identification on the basis of electronic mechanical braking system was proposed.Firstly,quarter vehicle braking model was established through Simulink.Next,the differences of adhesion coefficient on different road conditions and the variation rules of adhesion coefficient and wheel angle de-celeration were analyzed.An efficient and accurate road identification algorithm was designed to estimate the opti-mal slip rate of the current road surface.Finally,an ABS control strategy based on integral sliding mode control was designed to track the optimal slip rate.The simulation results showed that the road identification algorithm had fast response and high accuracy.The designed ABS control strategy could stably track the optimal slip rate and had strong adaptability to different road conditions.Compared with the traditional braking system based on logical threshold control,on single road condition the braking time was reduced by 11.89％,and the braking distance was shortened by 12.7％.On variable road condition the braking time was reduced by 17.8％,and the braking distance was shortened by 19.9％.关键词
