The invention discloses a commercial vehicle power system output power control method, a vehicle, electronic equipment and a storage medium. The commercial vehicle power system output power control method comprises the steps that the maximum allowable discharge power of a battery is obtained according to current vehicle weight information and driving road slope information; obtaining a limited torque value according to the maximum driving power of the motor, the maximum discharging power of the battery and the maximum allowable discharging power of the battery under the corresponding current vehicle weight information and the driving road gradient information; obtaining a target driving request torque according to the limited torque value and the driver demand torque; and controlling the output power of the commercial vehicle power system according to the target driving request torque. By adopting the method, the purposes of automatically adapting to the power limitation of the power system and having different power limitations under different driving working conditions can be achieved by obtaining the current driving information of the vehicle, finally, the power system of the vehicle is always operated in a reasonable working interval under different working conditions, and the purpose of reducing the driving energy consumption is achieved.

    本发明公开了一种商用车动力系统输出功率的控制方法、车辆、电子设备和存储介质,商用车动力系统输出功率的控制方法包括:根据当前车重信息和行驶道路坡度信息获得电池最大允许放电功率;根据电机最大驱动功率、电池最大放电功率和对应当前车重信息、行驶道路坡度信息下的电池最大允许放电功率获得限制扭矩值;根据限制扭矩值和驾驶员需求扭矩获得目标驱动请求扭矩;根据目标驱动请求扭矩控制商用车动力系统的输出功率。采用该方法可以通过获取车辆当前行驶信息,自动适应动力系统功率限制,不同驾驶工况下有不同的功率限制的目的,最终使车辆在不同工况下动力系统始终运行在合理工作区间,达到降低驱动能耗的目的。
