The invention is suitable for the technical field of vehicle control, and particularly relates to an energy management method and system of a hybrid power vehicle and the vehicle. The method comprises the steps that when a preset long-distance mode is started, the real-time traveled distance and the real-time remaining pure electric mileage between the current position of a vehicle and a navigation destination are detected in real time, and when the real-time remaining pure electric mileage is smaller than the real-time traveled distance, if the vehicle is in a high-speed working condition, the vehicle is in the high-speed working condition. If yes, an engine is controlled to be started to drive the vehicle and enable the engine to work in the optimal efficiency interval, and a long-distance mode is configured for the vehicle, so that the hybrid engine is efficiently controlled by combining the actual pure electric mileage and the navigation mileage, and the fuel economy is improved; the fuel consumption increase caused by frequent starting and stopping of an engine due to the fact that the electric quantity is reduced to be near a balance electric quantity point when pure electric driving is preferentially used can be avoided.
本申请适用于车辆控制技术领域,尤其涉及一种混合动力车辆的能量管理方法、系统及车辆。该方法在启动预设的长途模式时,实时检测车辆的当前位置与导航目的地之间的实时行驶里程和实时剩余纯电里程,当所述实时剩余纯电里程小于所述实时行驶里程时,若所述车辆处于高速工况,则控制启动发动机驱动所述车辆并使能所述发动机工作在最佳效率区间,为车辆配置长途模式,从而结合实际纯电里程和导航里程对混动的发动机进行高效控制,从而提高燃油经济性,可以避免优先使用纯电驱动导致电量降低至平衡电量点附近,导致的发动机频繁的启停造成的油耗增加。
