The invention provides an endurance mileage prediction method and device and a vehicle, and the prediction method comprises the steps: calculating the motor torque of the vehicle at least according to the average resistance, calculating the motor rotating speed at least according to the average running speed of the vehicle, and calculating the endurance mileage of the vehicle at least according to the motor torque, the motor rotating speed and the power conversion efficiency; determining future driving energy consumption of the vehicle; the future average energy consumption of the vehicle is determined based on the future driving energy consumption, the historical driving energy consumption and the future average energy consumption of the accessories, and the future average energy consumption of the accessories is the average energy consumption of the accessories arranged on the vehicle; according to the method, the endurance mileage of the vehicle is predicted based on the residual energy of the power battery and the future average energy consumption, so that the predicted endurance mileage of the vehicle is relatively accurate, the anxiety problem that a user cannot accurately predict the endurance mileage of the vehicle when using a new energy vehicle is relieved, and the user experience is improved. Therefore, the problem that the endurance mileage of the new energy vehicle is difficult to predict accurately in the prior art is solved.

    本申请提供了一种续航里程的预测方法、预测装置与车辆,该预测方法包括:至少根据平均阻力,计算车辆的电机扭矩,以及至少根据车辆的平均行驶速度,计算电机转速,且至少根据电机扭矩、电机转速和功率转换效率,确定车辆的未来驱动能耗;基于未来驱动能耗、历史驱动能耗以及未来附件平均能耗,确定车辆的未来平均能耗,未来附件平均能耗为车辆上配备的附件的平均能耗;基于动力电池的剩余能量以及未来平均能耗,预测车辆的续航里程,这样保证了预测的车辆的续航里程较为准确,从而缓解了用户在使用新能源车辆,对车辆的续航里程预测不准确的焦虑问题,进而解决了现有技术难以较为准确地对新能源车辆的续航里程进行预测的问题。
