The invention relates to the technical field of electronic appliances, and provides a mode switching method and device of a hybrid power system, a vehicle and a storage medium. The method comprises the steps of periodically obtaining current state information of a vehicle; according to the current state information, system power losses of the vehicle in different driving modes are determined; comparing the system power loss of the different driving modes, and outputting the driving mode corresponding to the minimum value of the system power loss; and according to a preset switching strategy, the vehicle is controlled to be switched to a driving mode corresponding to the minimum value of the system power loss. By means of the mode switching method, the energy consumption of the whole vehicle can be reduced, and it is ensured that the system efficiency is always in the optimal state.

    本公开涉及电子电器技术领域,提供了一种混合动力系统的模式切换方法、装置、车辆及存储介质。所述方法包括周期性地获取车辆的当前状态信息;根据所述当前状态信息,分别确定所述车辆在不同驱动模式下的系统功率损失;比较所述不同驱动模式的系统功率损失,并输出系统功率损失最小值对应的驱动模式;根据预设切换策略,控制所述车辆切换至所述系统功率损失最小值对应的驱动模式。采用本公开的模式切换方法,能够降低整车能耗,确保系统效率始终处于最优状态。
