The invention relates to a vehicle speed control method and device based on fuzzy control and a vehicle speed control system. The invention belongs to the technical field of vehicle control, accordingto the invention, the vehicle speed deviation value between the vehicle speed given value and the actual vehicle speed is calculated; a load deviation value between the load given value and the actual load is used as an input quantity for fuzzy control to perform fuzzy processing; according to a set first fuzzy control rule, fuzzy reasoning is carried out on the input quantity; then defuzzification processing is carried out; finally, a vehicle speed adjustment value is obtained; the vehicle speed is adjusted according to the vehicle speed adjustment value, online adjustment of the speed of the vehicle under different loads and combined control of overspeed and overload can be achieved, the dynamic load effect of the vehicle on the road surface can be reduced, the service life of the roadsurface is prolonged, safe driving of the vehicle is guaranteed, and personal safety of drivers and passengers in the vehicle is guaranteed. Moreover, the vehicle speed can be accurately and timely controlled, the adjusting time is short, the control effect is good, the control precision is high, and the adaptability is high.

    本发明涉及基于模糊控制的车辆速度控制方法、装置及车速控制系统,属于车辆控制技术领域,本发明将车速给定值与实际车速之间的车速偏差值,以及载重给定值与实际载重之间的载重偏差值作为用于模糊控制的输入量,进行模糊化处理,并根据设定好的第一模糊控制规则,对输入量进行模糊推理,再经过解模糊化处理,最终得到一个车速调整值,按照此车速调整值调整车速大小,能够实现车辆在不同载重下速度的在线调节和超速超载的联合控制,不仅能够降低车辆对路面的动载效应,延长路面的使用寿命,还保证车辆安全行驶,保障了车中驾驶员及乘客的人身安全。并且,本发明可以实现车速的准确及时控制,调节时间短,控制效果较好,控制精度高并且适应性强。
