摘要
提出一种基于PID控制器实现定速模式、模糊控制器实现跟车模式的自动巡航控制策略。该控制方法使用不同的控制器控制两种巡航模式,保留了两种控制器的优点,又避免了单一控制系统控制品质的下降,并利用Matlab/Simulink软件建立汽车纵向动力学、发动机和控制器模型。仿真结果表明所设计的控制系统具有可行性和有效性。
A kind of automatic cruise control strategy is put forward by PID controller and fuzzy controller, which realizes a constant speed mode and a car following model. This con- trol method uses different way to control two cruise modes, which not only retains both the advantages of the two kinds of controller, but also effectively avoids the single control sys- tem to decline control quality. And Matlab/Simulink software is adopted to establish vehicle longitudinal dynamics model, engine model and controller model. Simulation results show that the designed control system has good feasibility and effectiveness.
