The invention provides an engine stop control method and device, a vehicle and a storage medium, and the method comprises the following steps: when the current driving mode of the vehicle is an idle speed hybrid power four-wheel drive mode, if it is detected that the preset condition of engine stop is met, performing torque reduction control on an engine to reduce the output torque of the engine; in the idling hybrid power four-wheel drive mode, the first clutch is in a sliding friction state, the second clutch is in a closed state, the engine is in an idling state, the rear drive motor is in a driving state, and the engine drives a front drive motor of the vehicle to rotate so that the front drive motor can charge a battery pack; when it is detected that the output torque of the engine is reduced to a first preset torque threshold value, an engine stop request is sent to an engine controller; and the first clutch is controlled to enter a disconnected state from the sliding friction state, and the second clutch is controlled to enter the disconnected state from the closed state. According to the method, the engine in the hybrid vehicle can be reasonably controlled to stop, so that the influence on the service life of the engine is avoided.

    本申请提供了一种发动机停机的控制方法、装置、车辆和存储介质,该方法包括:当车辆的当前驾驶模式为怠速混动四驱模式时,若检测到满足发动机停机的预设条件,则对发动机进行降扭控制以降低发动机的输出扭矩;在怠速混动四驱模式下,第一离合器处于滑磨状态,第二离合器处于闭合状态,发动机处于怠速状态,后驱电机处于驱动状态,发动机驱动车辆的前驱电机转动,以使前驱电机为电池包充电;在检测到发动机的输出扭矩降低至第一预设扭矩阈值时,向发动机控制器发送发动机停止请求;控制第一离合器从滑磨状态进入断开状态,并控制第二离合器从闭合状态进入断开状态。该方法能够合理的控制混动车辆中的发动机停机,以避免对于发动机寿命的影响。
