The invention provides a driving range estimation method and device and a vehicle, and the method comprises the steps: obtaining the real-time target energy consumption of the vehicle based on the vehicle speed and the current and voltage of a drive motor when an engine is started and the vehicle speed is greater than a preset vehicle speed; obtaining the residual fuel quantity, and calculating equivalent electric quantity according to the residual fuel quantity; and calculating the driving range based on the equivalent electric quantity and the target energy consumption. According to the technical scheme provided by the invention, the problem that the accuracy of the driving range calculation of the existing extended-range vehicle is relatively low is solved.

    本发明提供一种续驶里程估算方法、装置及车辆,其中,所述续驶里程估算方法包括:在发动机启动且车速大于预设车速时,基于车速、驱动电机的电流及电压获取车辆的实时目标能耗;获取剩余燃油量,并根据所述剩余燃油量计算等效电量;基于所述等效电量及所述目标能耗计算续驶里程。本发明提供的技术方案解决了现有的增程式车辆续驶里程计算的准确性较低的问题。
