The embodiment of the invention discloses a power distribution method, device and equipment of a vehicle power system and a medium. The vehicle power system is applied to a vehicle comprising a tractor and a trailer. The power distribution method comprises the following steps: firstly, obtaining a whole vehicle load capacity and a whole vehicle demand torque; according to the load capacity of the whole vehicle, based on the preset mapping relation between the energy consumption of the tractor and the torque and based on the preset mapping relation between the energy consumption of the trailer and the torque, power distribution is conducted on the demand torque of the whole vehicle, so that the first target demand torque corresponding to the tractor and the second target demand torque corresponding to the trailer are determined; wherein the sum of the energy consumption of the tractor corresponding to the first target demand torque and the energy consumption of the trailer corresponding to the second target demand torque is minimum. By means of the method, the corresponding power distribution result of the tractor and the trailer when the energy consumption of the whole vehicle is the lowest is determined, the power performance of the whole vehicle is improved, the fuel saving rate is increased, the service life of the whole vehicle is prolonged, and then the energy consumption economical potential and the maximum cruising ability of a vehicle power system are excavated.

    本发明实施例公开了一种车辆动力系统的动力分配方法、装置、设备及介质,该车辆动力系统应用于包括牵引车和挂车的车辆中;该动力分配方法首先获取整车载重量和整车需求扭矩;然后根据整车载重量,并基于牵引车能耗与扭矩的预设映射关系,以及,基于挂车能耗与扭矩的预设映射关系,对整车需求扭矩进行动力分配,以确定牵引车对应的第一目标需求扭矩,挂车对应的第二目标需求扭矩;其中,第一目标需求扭矩对应的牵引车的能耗与第二目标需求扭矩对应的挂车的能耗之和最小。利用上述方法,确定出整车能耗最低时对应的牵引车与挂车的动力分配结果,提高整车的动力性,提高节油率及整车寿命,进而挖掘出车辆动力系统的能耗经济性潜力和最大续航能力。
