The invention discloses an idle speed control method of an engine, a storage medium and a vehicle. The method comprises the steps that the residual charge quantity of a power battery and the actual motor rotating speed of an engine of the hybrid vehicle under the idling working condition are obtained; in response to the fact that the residual charge quantity is smaller than the preset charge quantity and the actual motor rotating speed is smaller than the preset rotating speed, the power generation torque of a driving motor in the hybrid vehicle is reduced, and the feedforward torque of an engine is increased; determining the actual charging power of the power battery; and determining whether to control the engine to stop based on the actual charging power. The technical problem that the stability is low under engine idle speed control is solved.

    本发明公开了一种发动机的怠速控制方法、存储介质以及车辆。其中,该方法包括:获取混动车辆在怠速工况下动力电池的剩余电荷量和发动机的实际电机转速;响应于剩余电荷量小于预设电荷量且实际电机转速小于预设转速,降低混动车辆中驱动电机的发电扭矩,并提高发动机的前馈扭矩;确定动力电池的实际充电功率;基于实际充电功率,确定是否控制发动机停机。本发明解决了发动机怠速控制下稳定性较低的技术问题。
