摘要
基于有限状态机(FSM)理论和模糊逻辑控制理论,设计了具有主动安全性的汽车自适应巡航控制(ACC)系统。建立了车辆动力传动系统模型,通过对节气门和制动器的控制仿真模拟了汽车ACC系统的工作过程。仿真结果表明:基于有限状态机理论的汽车ACC系统能使车辆沿着巡航行驶时的有限状态自动切换,并准确跟踪期望加速度,使车辆在加速行驶、车辆跟踪和制动减速等行驶工况下保持跟踪性和适应性。
We design a vehicle adaptive cruise control(ACC) system that has active safety,using the finite state machine(FSM) theory and the fuzzy logic control theory.First,we establish the model of the vehicle′s power transmission system.Then we simulate the control of the throttle angle and brake pressure of the ACC system.The simulation results show that the ACC system thus designed controlled can make the vehicle automatically switch into the finite state and follow the desired acceleration command and that the ACC system can provide such satisfactory performances as acceleration,vehicle tracking and braking.
