2、；防抱死制动系统；控制技术 3 Abstract As a kind of active security equipment in vehicle，Antilock Braking Systems(ABS)has been used a11 over the worldThe road surface conditions vary from dry to iceThere are hysteresis in the actuator of ABSAll these factors result in difficulty of controller design course of ABS

3、The main difficulty arising in the design of Antilock Braking Systems(ABS) controller is due to the strong nonlinearity in the pmblemThe most important process parameters affecting the quality of control are the coefficiet of friction between tire and road， the tire slip ratio，and the vertical force

4、 on the wheel. This article introduced the automobile anti-lock braking system control principle briefly. The control technology which uses to the present automobile anti-lock braking system has carried on the summary, and has carried on the forecast to its trend of development. Keywords: vehicle；Antilock Braking Systems；Control technology 4 1. 概述 1.1 采用 ABS 系统的必要性 a. 传统制动系统制动过程：汽车在紧急
