The invention discloses a new energy vehicle endurance mileage estimation method, device and equipment and a medium. The method comprises the following steps: acquiring residual available energy, real-time load and real-time vehicle speed of a whole vehicle in a current state; based on the vehicle running mode, the vehicle running speed and the vehicle load, the incidence relation between the whole vehicle load and the vehicle driving energy consumption is built; according to the incidence relation between the whole vehicle load and the vehicle driving energy, the required driving energy consumption of the vehicle at the real-time load and the real-time vehicle speed is determined; and determining the endurance mileage of the vehicle according to the magnitude relationship between the remaining available energy and the required driving energy consumption. The technical problem that in the prior art, the endurance mileage estimation accuracy is low due to the fact that the difference between the endurance mileage and the running time and the actual value is large due to the large load change difference of the whole commercial vehicle is solved.

    本发明公开了一种新能源车辆续航里程预估方法、装置、设备和介质,方法包括:获取当前状态下整车的剩余可使用能量、实时载重和实时车速;基于车辆运行模式、车辆行驶速度和车辆载重,构建整车载重与车辆驱动能耗之间的关联关系;根据所述整车载重与车辆驱动能之间的关联关系,确定车辆处于所述实时载重和所述实时车速时的所需驱动能耗;根据所述剩余可使用能量、所述所需驱动能耗之间的大小关系,确定车辆的续航里程。本发明解决了现有技术中商用车整车载重变化差异大导致续航里程与行驶时间与实际差别较大,从而导致续航里程估算准确率低的技术问题。
