The invention provides a vehicle energy management method, a storage medium and a vehicle, and belongs to the technical field of vehicles. The method comprises the following steps: firstly, determining whether a vehicle meets a power fixed-point strategy activation condition based on state information of the vehicle; then, under the condition that the vehicle meets the power fixed-point strategy activation condition, the engine is controlled to operate at the initial engine rotating speed, the target fuel economic interval of the engine is determined based on the initial engine rotating speed, and then optimization calculation is conducted on the equivalent fuel consumption minimum strategy model based on the target fuel economic interval; determining a target engine working point; and finally, based on the target engine working point, the engine is controlled. Thus, by combining the power fixed-point strategy and the equivalent fuel consumption minimum strategy model, it can be guaranteed that the engine stably runs in the vehicle running process, the engine can be controlled to run at the target engine working point with the optimal efficiency, and then the fuel economy of the whole vehicle is effectively improved.
本申请提供了一种车辆能量管理方法、存储介质和车辆,属于车辆技术领域。本申请实施例首先基于车辆的状态信息,确定车辆是否满足功率定点策略激活条件;然后在车辆满足功率定点策略激活条件的情况下,控制发动机保持初始发动机转速运行,并基于初始发动机转速,确定发动机的目标燃油经济区间,进而基于目标燃油经济区间,对等效燃油消耗最小策略模型进行寻优计算,确定目标发动机工作点;最后基于目标发动机工作点,对发动机进行控制。如此,通过将功率定点策略和等效燃油消耗最小策略模型结合,不仅能够保证发动机在车辆行驶过程中稳定运行,还能控制发动机在效率最优的目标发动机工作点运行,进而有效提高整车的燃油经济性。
