汽车ABS控制联合仿真分析

Analysis on Co-simulation of Vehicle ABS Control

为了更加高效地对实际应用前的整车ABS控制器匹配效果进行验证,该文采用Car Sim/Simulink软件联合建立仿真模型,在低附着系数路面和对开路面制动进行ABS的PID控制模型仿真分析,进一步验证了有ABS和无ABS的汽车对于制动距离、横摆角速度、四轮与车身速度变化及四轮滑移率等参数的控制效果,从而有效证明了该方法的可行性,对于开发整车ABS控制器具有指导意义。

In order to verify vehicle ABS controller effectively, the co-simulation model is buih using CarSim/Simulink. PID simulation model is analyzed in the condition of low adhesion coefficient and bisectional pavement to turther verify control effect with and without ABS on braking distance, yawing velocity, four-wheel and vehicle speed change and four-wheel slip rate, therefore this method is feasible and has great significance for the development of vehicle ABS controller.
