摘　　要：相对于传统的液压式或气压式制动系统,电子机械式制动系统因具有结构简单、响应时间短以及制动效率高等优点正受到越来越高的重视.在设计出一套电子机械式制动装置模型的基础上,提出了一种适合安装有电子机械式制动系统的整车制动防抱死滑模变结构控制器.通过动力学仿真软件Carsim建立整车仿真模型,并与Simulink进行联合控制仿真.将仿真结果与传统的基于逻辑门限值控制的液压制动器制动性能进行比较,验证了滑模变结构控制方法在安装有电子机械式制动系统的整车制动防抱死系统上的有效性及制动性能的优越性.Compared with the traditional hydraulic brake system or the pneumatic braking system,the electromechanical brake is being paid increasing attention due to its simple structure, shortresponse time and high braking efficiency. Therefore,based on the as-designed electromechanicalbrake device, a variable structure controller with sliding mode for anti-lock braking system （ ABS ）was proposed. A vehicle model which was built in the Carsim and control system was designed inSimulink. Th en , a co-simulation was conducted between the Carsim and the Simulink. B ycomparing with the braking performance of the traditional hydraulic brake, using the logicthreshold method with the electromechanical brake, it was verified that variable structure controlwith sliding mode method for anti-lock braking system is effective in vehicle equipping with theelectromechanical brake system and advanced in braking performance.
