Study on Control Logic for Anti-lock Braking System Based on MATLAB

汽车防抱死制动系统(ABS)是一种很重要的汽车主动安全技术,而寻找理想的控制逻辑规律是车辆防抱制动系统研究与开发的重点。在MATLAB/Simulink仿真环境下利用Stateflow建立了有限状态机模型,实现了带防抱制动系统(ABS)的车辆动力学模型的计算机仿真。仿真结果表明,该系统能比较真实地反映汽车ABS系统的实际工作过程,达到了满意的控制效果。

Anti-lock braking system （ABS） is a very important active safety technology of automobiles, and searching for an ideal logic principle has been the key for the research and development of vehicle anti-lock braking system （ABS）. This paper, based on MATLAB/Simulink development environment, builds the definite state machine Stateflow model for the ABS electronic control unit. The simulation results show that this hybrid system can relatively be true to reflect the practical work process of ABS , and obtains satisfying system performance by debugging it.
