The embodiment of the invention discloses a driving range estimation method and device and an extended range vehicle. The driving range estimation method comprises the steps that the accumulated fuelinjection quantity of the vehicle is obtained under the condition that the duration after the vehicle is started is longer than the preset duration, and the remaining fuel quantity is calculated according to the accumulated fuel injection quantity; a current driving mode of the vehicle is obtained, and driving fuel consumption is obtained according to the driving mode; and the driving range is calculated according to the remaining fuel quantity and the driving fuel consumption. According to the technical scheme, the problems that deviation exists between the fuel quantity percentage and the real fuel quantity of an existing vehicle, and the calculation accuracy of the vehicle driving range is low are solved.

    本公开的实施例公开了一种续驶里程估算方法、装置及增程式车辆,其中,所述续驶里程估算方法包括:在车辆启动之后的时长大于预设时长的情况下,获取车辆的累计喷油量,并根据所述累计喷油量计算剩余燃油量;获取所述车辆的当前驱动模式,根据所述驱动模式获取驱动油耗;根据所述剩余燃油量及所述驱动油耗计算续驶里程。本发明提供的技术方案解决了现有车辆的油量百分比与真实燃油量存在偏差、车辆续驶里程计算的准确性较低的问题。
