The invention provides a vehicle load estimation method and device, a storage medium and electronic equipment, if a vehicle enters a kickdown mode, whether the gradient value of a road on which the vehicle runs currently is smaller than a gradient threshold value or not is judged, if yes, whether the current opening degree of a first accelerator pedal of the vehicle reaches a first opening degree threshold value or not is monitored, and if yes, the vehicle load is estimated. Whether the vehicle is in a torque following state or not is judged based on the actual torque and the required torque of the vehicle engine, if yes, the actual rotating speed change value and the theoretical rotating speed change value of an input shaft of the vehicle within the preset time are obtained, the actual rotating speed change value and the theoretical rotating speed change value are compared, and the load of the vehicle is determined based on the comparison result. According to the scheme, under the condition that the running state of the vehicle meets the condition, the actual rotating speed change value of the input shaft of the vehicle is calculated, the actual rotating speed change value is compared with the theoretical rotating speed change value, the load of the vehicle is obtained, and the purpose of accurately estimating the load of the vehicle while the cost is low is achieved.

    本发明提供一种车辆载重的预估方法及装置、存储介质、电子设备,若车辆进入kickdown模式,则判断车辆当前行驶的道路的坡度值是否小于坡度阈值,若是,则监测车辆当前的第一油门踏板开度是否达到第一开度阈值,若达到,基于车辆发动机的实际扭矩和需求扭矩判断车辆是否处于扭矩跟随状态,若是,则获取车辆的输入轴在预设时间内的实际转速变化值和理论转速变化值,将实际转速变化值和理论转速变化值进行比较,基于比较结果确定车辆的载重。在本方案中,在车辆行驶状态满足条件的情况下,计算车辆的输入轴的实际转速变化值,将实际转速变化值与理论转速变化值比较,得到车辆的载重,以实现低成本的同时准确预估车辆载重的目的。
