摘要
设计了一个模糊控制器,来控制自适应巡航系统中的自动制动系统,它能够自动判定汽车行驶安全状态并在危险时自行制动。模糊控制器模仿人类思维方式,根据自车和前车之间的距离和相对速度,输出不同的制动强度,以保证制动过程中的平稳性与驾乘舒适性。通过在Matlab/Simulink中建立系统模型,在不同的工况下进行系统仿真。仿真结果表明系统具有较好的制动效果并可保证减速过程中汽车行驶的平稳性。
A fuzzy controller is designed for controlling the automatic braking devise in adaptive cruise system.The controller can judge the driving safety status of vehicle and apply brake automatically in dangerous situation.By imitating the human being＇s way of thinking,fuzzy controller exerts different braking forces,depending on the distance and relative speed between self vehicle and front vehicle,to assure braking smoothness and ride comfort.The system simulation is conducted on the system model built with Matlab/Simulink in different working conditions.The results of simulation show that the system can achieve better braking effects and assure the driving smoothness of vehicle in deceleration process.
