The invention discloses a whole vehicle weight determination method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining a corresponding driving motor rotating speed, a target torque, an actual torque and a whole vehicle speed of a target vehicle within a preset time period in the driving process of the target vehicle; according to the corresponding driving motor rotating speed and the actual torque of the target vehicle within the preset duration, the average power consumption value and the average resistance acting value of the driving motor within the preset duration are determined; according to the average power consumption value and the average resistance acting value of the driving motor, the whole vehicle kinetic energy corresponding to the target vehicle is determined; according to the whole vehicle kinetic energy and the whole vehicle speed, the predicted weight corresponding to the target vehicle is determined, the predicted weight is adjusted, and the target weight corresponding to the target vehicle is obtained. According to the technical scheme, the precision of the whole vehicle weight determination result can be improved, and the vehicle maintenance cost is reduced.

    本发明公开了一种整车重量确定方法、装置、车辆及存储介质,包括:在目标车辆的行驶过程中,获取目标车辆在预设时长内对应的驱动电机转速、目标转矩、实际转矩以及整车车速;根据目标车辆在预设时长内对应的驱动电机转速以及实际转矩,确定预设时长内驱动电机的平均功耗值以及阻力平均做功值;根据驱动电机的平均功耗值以及阻力平均做功值,确定目标车辆对应的整车动能;根据整车动能以及整车车速,确定目标车辆对应的预测重量,并对预测重量进行调整,得到目标车辆对应的目标重量。本发明实施例的技术方案可以提高整车重量确定结果的精度,降低车辆维护成本。
