The invention provides a hybrid vehicle energy management method, device and equipment and a storage medium, and relates to the technical field of vehicles. According to the method, the vehicle power demand and the current battery capacity of the hybrid vehicle are obtained, and when the current battery capacity is larger than the battery capacity lower limit value and the vehicle power demand is larger than the engine operation power lower limit, the power distribution coefficient lambda of the hybrid vehicle in the hybrid operation mode is determined according to the power source system efficiency; the power distribution coefficient lambda is used for indicating power distribution of an engine and a battery, the hybrid vehicle is controlled to operate in a sub-mode corresponding to the power distribution coefficient lambda according to the power distribution coefficient lambda, and different lambda corresponds to different sub-modes. According to the hybrid vehicle energy management method provided by the invention, the overall system efficiency of the hybrid vehicle is improved, so that the fuel economy of the hybrid vehicle is optimal.

    本申请提供一种混动车辆能量管理方法、装置、设备及存储介质,涉及车辆技术领域。该方法通过获取混动车辆的车辆功率需求和当前电池电量,在当前电池电量大于电池电量下限值,并且车辆功率需求大于发动机运行功率下限时,根据动力源系统效率确定混动车辆在混动运行模式中的动力分配系数λ,动力分配系数λ用于指示发动机和电池的动力分配,根据动力分配系数λ控制混动车辆在动力分配系数λ对应的子模式上运行,其中,不同的λ对应不同的子模式,因此本申请提供的一种混动车辆能量管理方法通过提升混合动力汽车的总体系统效率,使得混合动力汽车的燃油经济性达到最佳。
