The invention relates to the technical field of operation machinery, and provides a vehicle overspeed protection method, an overspeed protection control device and a vehicle. The overspeed protection method of the vehicle comprises the steps that the current state of the vehicle is obtained, wherein the current state comprises at least one of the current inclination angle of the vehicle and the current rotating speed of an engine of the vehicle; when it is determined that the current state is within the first preset condition, the air inflow of an engine of the vehicle is controlled to be reduced, and/or the fuel injection quantity of a fuel injector of the engine is controlled to be reduced; determining that the current state is in a second preset condition, and controlling a brake electromagnetic valve of the engine to be opened; determining that the current state is in a third preset condition, and controlling a braking system of the vehicle to brake; wherein the threshold value of the first preset condition is smaller than the threshold value of the second preset condition and smaller than the threshold value of the third preset condition. According to the overspeed protection method of the vehicle, the current inclination angle of the vehicle and the current rotating speed of the engine are judged, the braking acting force is provided in a grading mode, automatic braking is achieved, and overspeed of the vehicle is avoided.
本发明涉及作业机械技术领域,提供一种车辆的超速保护方法、超速保护控制装置及车辆。车辆的超速保护方法包括:获取车辆的当前状态,当前状态包括车辆的当前倾角与车辆的发动机的当前转速中的至少一个;确定当前状态在第一预设条件内,控制车辆的发动机的进气量减少,和/或,控制发动机的喷油器的喷油量减小;确定当前状态在第二预设条件内,控制所述发动机的制动电磁阀打开;确定当前状态在第三预设条件内,控制车辆的制动系统制动;其中,第一预设条件的阈值小于第二预设条件的阈值小于第三预设条件的阈值。本发明提供的车辆的超速保护方法,通过判断车辆的当前倾角与发动机的当前转速,分级提供制动作用力,自动制动,避免车辆超速。
