The invention discloses an anti-overspeed control method and device for an electrically driven vehicle, the vehicle and a medium. The method comprises the steps that when it is monitored that a vehicle is started, vehicle data are obtained in real time, and the final vehicle weight is calculated through the vehicle data; when it is detected that the vehicle meets a slope calculation condition, calculating an estimated slope value according to the final weight of the whole vehicle; and according to the final weight of the whole vehicle and the estimated slope value, an output reverse dragging torque value is determined, and anti-overspeed control is conducted on the vehicle according to the reverse dragging torque value. According to the technical scheme of the embodiment of the invention, two methods for calculating the weight of the whole vehicle are provided, the accuracy of calculating the weight of the whole vehicle is improved, and meanwhile, the downhill road section is accurately identified, so that the slope value of the vehicle on the downhill road section is calculated after the accurate weight of the whole vehicle is obtained, and the calculation accuracy is improved. And finally, the output reverse dragging torque value is controlled according to the slope value and the whole vehicle weight, so that anti-overspeed control over the transport vehicle on the downhill road section is achieved, and the effect is good.

    本发明公开了一种电驱动车辆防超速控制方法、装置、车辆及介质。该方法包括:当监测到车辆启动时,实时获取整车数据,并通过整车数据计算最终整车重量;当检测到所述车辆满足坡度计算条件时,根据所述最终整车重量进行预估坡度值的计算;根据最终整车重量以及预估坡度值,确定输出的反拖转矩值,并按照所述反拖转矩值对车辆进行防超速控制。本发明实施例的技术方案,提出了两种整车重量的计算方法,提高了计算整车重量的精确性,同时对下坡路段进行了准确识别,从而在求得准确的整车重量后计算得到车辆在下坡路段的坡度值,最后根据坡度值以及整车重量来控制输出的反拖转矩值从而实现了对处于下坡路段的运输车辆防超速控制,效果良好。
