摘　　要：汽车防抱死制动系统(ABS)是一种很关键的汽车主动安全技术。本文采用基于有限状态机的系统仿真方法,采用Simulink和Stateflow模块混合建模,对ABS模型中的连续系统和离散系统进行仿真。仿真结果表明,该混合仿真系统能比较真实地反映汽车ABS系统的实际工作过程,显著缩短制动距离,提高安全性。The anti-lock braking system（ABS）is a very pivotal active safety technology of automobiles. This paper adopts the method of system simulating based on finite state machine, simulates the continuous system and discrete system of ABS model by used Simulink and Stateflow modules to set up the hybrid model. The simulation results show that this hybrid system can relatively be true to reflect the practical work process of ABS, and prove that the ABS can prominently shorten braking distance and improve the safety.
