The invention discloses an overspeed prevention method, device and equipment for a hydrostatic drive vehicle and a medium. The method comprises the following steps: acquiring whole vehicle driving data of a target vehicle in real time; when the whole vehicle speed in the whole vehicle driving data of the target vehicle is not zero, the overspeed prevention type of the target vehicle is judged according to the accelerator pedal state and the driving gear state in the whole vehicle driving data; when the overspeed prevention type is parking overspeed prevention, parking overspeed prevention control is executed for the target vehicle; and when the overspeed prevention type is driving overspeed prevention, the current overspeed prevention stage of the target vehicle is determined in real time according to preset overspeed prevention stage judgment conditions, and driving overspeed prevention control corresponding to different overspeed prevention stages is executed in stages. According to the technical scheme of the embodiment of the invention, anti-overspeed control can be automatically carried out when the hydrostatic driving running vehicle goes down a long slope or an abrupt slope, so that the pump and the motor are prevented from being damaged due to overspeed, the service life of the vehicle is prolonged, and meanwhile, the operation reliability of the whole machine is improved.
本发明公开了一种静液压驱动车辆防超速方法、装置、设备及介质。该方法包括:实时获取目标车辆的整车行驶数据;当目标车辆的整车行驶数据中的整车车速不为零时,根据整车行驶数据中的加速踏板状态以及行驶挡位状态判断目标车辆的防超速类型;当防超速类型为停车防超速时,为目标车辆执行停车防超速控制;当防超速类型为行车防超速时,根据预先设定的防超速阶段判定条件实时确定目标车辆当前所处的防超速阶段,并分阶段执行与不同防超速阶段分别对应的行车防超速控制。本发明实施例的技术方案在静液压驱动行驶车辆在下长坡或陡坡时能够自动进行防超速控制,进而防止泵和马达因超速而引起的损坏,提高车辆使用寿命的同时提升了整机作业的可靠性。
