摘　　要：通过在MATLAB上建立整车模型来模拟制动防抱死的控制过程。利用逻辑门限控制方法,实现液压系统对制动力的控制。并按照80km/h,60km/h,30km/h三种车速和三种不同制动强度z=0.7,z=0.5,z=0.1下的,仿真分析了制动强度,前后轮轮速和车速的变化,滑移率的变化等制动性指标。Through the establishment of the vehicle model on MATLAB, Which simulate the process of antilock braking system. The logic threshold control method can realize the control of braking force by the hydraulic system. And in accordance with 80krn/h, 60kin/h, 30km/h three kinds of speeds and three different brake strength z=0.7, z=0.5, z=0.1 under the simulation analysis of the braking distance, the front and rear wheel speed and vehicle speed changes, and changes in the braking slip ratio index.
