The invention provides a power-saving mode control method and device and an electric vehicle, and relates to the technical field of vehicle control, wherein the method comprises the steps: obtaining the state of a power-saving mode switch; and when the power-saving mode switch is in an on state, controlling the speed of the electric vehicle to be smaller than a preset speed, adjusting the currenttorque cloud picture to be a pre-stored torque cloud picture corresponding to the power-saving mode, setting the energy recovery level to be the highest level, and stopping diagnosing faults related to a controller which is powered off currently. According to the scheme, the driving range of the electric vehicle is increased, and it is ensured that the electric vehicle reaches a charging area before the electric quantity is exhausted.

    本发明提供一种省电模式控制方法、装置及电动汽车,涉及整车控制技术领域,所述方法包括:获取省电模式开关的状态;在所述省电模式开关为开启状态时,控制电动汽车的车速小于预设车速,调整当前扭矩云图为预先存储的与省电模式相对应的扭矩云图,设置能量回收的等级为最高等级,并停止诊断与当前断电的控制器相关的故障。本发明的方案提高了电动汽车的续驶里程,确保了电动汽车在电量耗尽之前到达充电区域。
