The invention belongs to the technical field of vehicles, and discloses a vehicle control unit control method, device and equipment and a storage medium. The method comprises the following steps: acquiring available power and real-time power sent by a battery pack management system; performing difference calculation according to the available power and the real-time power to obtain difference power; determining a current driving working condition according to the difference power and an overpower condition; and when the current driving working condition is the target driving working condition, the output torque of the motor is controlled according to the torque reduction strategy to prevent the battery pack from overpower. By simultaneously judging the difference between the available power signal of the battery pack and the real-time power signal of the battery pack, the protection strategy of the whole vehicle on the battery pack is intelligently started, so that the MCU control torque value is immediately reduced when the battery pack is close to overpower, the purpose of effectively preventing the battery pack from overpower during running of the pure electric vehicle is achieved, and the service life of the battery pack is prolonged. And the service life and the safety of the battery pack are effectively improved.

    本发明属于车辆技术领域,公开了一种整车控制器控制方法、装置、设备及存储介质。本发明通过获取电池包管理系统发送的可用功率和实时功率;根据所述可用功率和所述实时功率进行差值计算,得到差值功率;根据所述差值功率和超功率条件确定当前行驶工况;在当前行驶工况为目标行驶工况时,根据扭矩削减策略对电机输出扭矩进行控制,以防止电池包超功率。通过同时对电池包可用功率信号和电池包实时功率信号的差值判断,智能开启整车对电池包的保护策略,从而达到在电池包接近超功率时,立即削减MCU控制扭矩值,实现了有效防止纯电动汽车行车时电池包出现超功率的目的,有效提升了电池包使用寿命及安全性。
