The invention discloses a torque distribution method and device of a vehicle, the vehicle and a storage medium. The method comprises the following steps: judging whether a vehicle has a high-power driving demand and a charging demand according to vehicle state information; if the vehicle has the high-power driving demand and/or the vehicle has the charging demand, whether the heat provided by the heat management system meets the heating demand of the vehicle corresponding to the high-power driving demand and/or the charging demand or not is judged; and if the heat provided by the heat management system cannot meet the heating requirement of the vehicle, the vehicle is controlled to distribute the torque of each driving motor according to a second torque distribution mode so as to meet the heating requirement of the vehicle. When the vehicle is in the second torque distribution mode, the efficiency of the electric drive system is lower than a preset threshold value. When the vehicle is in the specific scene, if the heat provided by the heat management system cannot meet the heating requirement of the vehicle, the vehicle is controlled to distribute the torque of the driving motor according to the second torque distribution mode so as to meet the heating requirement of the vehicle.

    本发明公开了一种车辆的扭矩分配方法及其装置、车辆和存储介质。该方法包括:根据车辆状态信息判断车辆是否有大功率驱动需求及是否有充电需求;若车辆有大功率驱动需求和/或车辆有充电需求,判断热管理系统提供的热量是否满足与大功率驱动需求和/或充电需求对应的车辆的加热需求;若热管理系统提供的热量无法满足车辆的加热需求,控制车辆按照第二扭矩分配模式分配每个驱动电机的扭矩,以满足车辆的加热需求。车辆处于第二扭矩分配模式时,电驱系统的效率低于预设阈值。本发明中在车辆处于特定场景时,若热管理系统提供的热量无法满足车辆的加热需求,控制车辆按照第二扭矩分配模式分配驱动电机的扭矩,以满足车辆的加热需求。
