Matlab汽车防抱死制动系统PID控制的建模与仿真
传统制动系统刹车时间5.5s左右，刹车路程大约80m左右，0.5s车轮抱死；ABS刹车时间4s，刹车路程60m，没有出现抱死，可见ABS有明显的优越性。

Title Modeling and Simulation of PID Control of the Vehicle Anti-lock Braking System
Abstract
During braking, ABS can make it more ideal driving stability, anti-jamming ability and braking distance.
Time-varying, nonlinear and uncertainties are the properties of the car, so the control arithmetic of the braking system is the main factors affecting the braking performance. It introduces the basic concepts of PID control and parameter tuning of PID controllers and so on. By forcing analysis of the vehicle during braking, it sets up the necessary model of the vehicle, simplified dynamic model of vehicle, tire model based on the “Magic Formula”, and carrying out the simulation in MATLAB/Simulink environment. Still, vehicle anti-lock braking characteristic is analyzed On different road conditions.
Traditional braking system has about 5.5 seconds braking time, about 80 meters braking distance and need 0.5 seconds lock wheel. ABS has 4 seconds braking time, 60 meters braking distance and no locking. It means that ABS has obvious advantages.
