摘要
以ABS制动过程中的滑移率误差和滑移率的误差变化率作为模糊控制器(fuzzy controller)的输入量,以制动器的反馈压力作为模糊控制器的输出量,设计了一个双输入单输出的ABS(anti-lock brake system)模糊控制器,与已建立的各Simulink模块连接,组成了完整的ABS仿真模型.利用所建立的ABS仿真模型,针对柳州五菱汽车工业公司宏光系列车型以及结冰路面、湿沥青路面和干混凝土路面条件,进行了不同车速状态下的制动仿真分析.仿真结果表明:带模糊控制器的ABS,工作时车轮不仅不会出现抱死现象,且制动效果改善明显.
An ABS fuzzy controller with double inputs and single output is designed by taking the slip ratio error and error change rate of slip rate as the input and the brake pressure as the output.And a complete ABS simulation model is formed by connecting each Simulink module built.With the ABS simulation model,the car of Hongguang model made by Wuling Automobile Industry Company in Liuzhou is taken to make the brake simulation analysis respectively on the icy road,wet asphalt road and dry concrete road at different velocity.The simulation result shows that with the ABS fuzzy controller in a car,the wheel not only can't lock,but also can achieve a good braking effect.
