The invention relates to a vehicle charging torque determination method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the driving demand torque of the current vehicle, the battery charging and discharging demand torque and the accessory consumption torque, obtaining the engine demand torque, and determining the power-assisted torque limit values of a first engine to a third engine, the maximum value serves as a target engine power-assisted torque limit value, an engine torque limit value is obtained according to the smaller value of the engine noise load limit value and the target engine power-assisted torque limit value, and the engine residual torque is determined according to the engine torque limit value and the engine demand torque; meanwhile, the battery charging torque limit value is obtained according to the engine residual torque and the battery charging and discharging demand torque, the target charging torque is determined based on the battery charging torque limit value, the current vehicle is charged, and therefore the problem that the fuel economy of the engine is affected due to the fact that the consideration factor of the battery charging torque limit determining method is single is solved.

    本申请涉及一种车辆充电扭矩的确定方法、装置、车辆及存储介质,包括:获取当前车辆的驱动需求扭矩、电池充放电需求扭矩和附件消耗扭矩,得到发动机需求扭矩,分别确定第一发动机至第三发动机的可助力扭矩限值,并将其中最大值作为目标发动机可助力扭矩限值,根据发动机噪声负荷限值和目标发动机可助力扭矩限值中的较小值得到发动机扭矩限值,并根据发动机扭矩限值和发动机需求扭矩确定发动机剩余扭矩,同时根据发动机剩余扭矩和电池充放电需求扭矩得到电池充电扭矩限值,以基于电池充电扭矩限值确定目标充电扭矩并为当前车辆充电,由此,解决了电池充电扭矩限的确定方法考虑因素单一,从而影响发动机燃油经济性的问题。
