摘要： 汽车在行驶过程中，由于车轮完全抱死而出现的后轴侧向偏滑、前轮丧失本身转向能力的现象，而ABS系统能够很好地防止以上这些情况的发生，能够最大限度地改善汽车的制动性能，保证了汽车车轮的轮胎与路面间的附着力的变化情况，从而提高汽车在制动过程当中车轮的方向稳定性以及转向操纵能力的目的，满足了汽车在行驶过程中安全的需要。作为一种新型的混合动力电动汽车-插电式混合动力汽车，防抱死制动系统应该与电再生制动同时存在。再生制动系统是混合动力汽车当中的关键技术之一。插电式混合动力汽车最重要特性之一是其回收显著的制动能量的能力。利用再生制动系统可以将插电式混合动力汽车中的电动机被控制作为发电机运行，从而将车辆的动能或位能变换为电能，并储存在能量储存装置中，让能量得以再次利用。

Plug-in Hybrid Electric Vehicle Brake System Design based on Matlab
Abstract: In a moving vehicle, the rear axle side due to wheel fully locked partial slip, front wheel loses itself in ability of the steering, while the ABS system is able to prevent these situations, braking performance to maximize the improvement of vehicle, the changes of tire and road surface adhesion between the vehicle wheels in order to improve the stability, direction of automobile wheel in the braking process and the steering ability, meet the vehicle in motion the process of security needs. As a new type of hybrid electric vehicles and plug-in hybrid vehicle, antilock braking system should exist at the same time, and the electric regenerative braking. Regenerative braking system is one of the key technologies of hybrid vehicles. Plug in hybrid electric vehicle is one of the most important characteristics of the braking energy recovery significantly ability. The regenerative braking system can be motor plug in hybrid electric vehicle is in control as a generator, thus the vehicle kinetic energy and potential energy is transformed into electric energy, and stored in the energy storage device, let the energy to be used again.
In this paper describes the automobile antilock braking system and regenerative braking system development history, research status at home and abroad, the basic principle, focuses on the related mathematical modeling of antilock braking system model and the tire model were established, suitable for simulation of vehicle capable of single wheel vehicle model in the straight line braking process, and according to the characteristics of fuzzy PID control in the Matlab/Simulink environment of automobile brake system model, a PID control as the control module, the simulation research of mathematical automobile ABS braking system model, gives the simulation curve, verify the car braking system with maneuverability good braking performance and direction.
