摘要
为提高汽车行驶的主动安全性及缓解司机驾驭汽车的疲劳感,提出了汽车巡航智能跟随控制方法.应用模糊控制理论,以前车和巡航车间理论安全距离与实际相对距离偏差及两车速度偏差作为控制变量,设计智能巡航模糊逻辑控制器,将油门开度或制动踏板行程作为控制器输出变量,实现汽车巡航的智能跟随控制.利用Matlab/Simulink针对智能跟随控制功能实施了仿真验证,结果表明:设计的智能巡航模糊控制器能够有效地跟随前方车辆行驶并始终保持两车间的安全距离,说明该控制器具备较强的鲁棒性.
In order to alleviate the driving fatigue and increase automobile active safety, an intelligent following control method on automobile cruise system is proposed. Adopting the fuzzy control theory, an intelligent following control method of automobile cruise is put forward. Using the relative velocity and the deviation of safe distance and relative distance between the preceding car and the cruise vehicle as the input variable of the fuzzy logic controller, the throttle position or the braking pedal travel is obtained based on fuzzy control rules. Using MATLAB/Simulink, the control function on the intelligent following control is simulated and the results show that the controller on automobile intelligent cruise has good robustness and can follow automatically the preceding car on the conditions of keeping the safety distance.
