The invention discloses a range-extended vehicle energy management method and device. The range-extended vehicle energy management method comprises the steps that vehicle total energy needed by a driving road section, battery energy provided by a vehicle battery and a first starting threshold value of a range extender are obtained; according to the battery energy and a first opening threshold value, the pure electricity endurance mileage provided by the vehicle battery under the condition that the range extender is not triggered is determined; and based on the pure electric endurance mileage and the total energy of the vehicle, a first starting threshold value of the range extender is adjusted, and therefore the problems that in the prior art, when the SOC is too low, the range extender is started, vehicle power is insufficient, and NVH is reduced are solved.

    本发明公开了一种增程式车辆能量管理方法及装置,包括:获取行驶路段所需的车辆总能量、车辆电池所提供的电池能量和增程器的第一开启阈值;根据所述电池能量与第一开启阈值确定在不触发所述增程器的情况下,所述车辆电池所提供的纯电续航里程;基于所述纯电续航里程和所述车辆总能量,调整所述增程器的第一开启阈值,从而解决了现有技术中SOC过低时启动增程器带来的车辆动力不足、NVH降低的问题。
