The invention provides an engine idle speed control method of a hybrid vehicle, a storage medium and the vehicle, and belongs to the technical field of vehicle control. According to the embodiment of the invention, a trigger mode of an idle speed working condition of an engine is recognized, a corresponding target proportional-integral control strategy can be matched based on the trigger mode of the idle speed working condition of the engine, and the control accuracy of the engine is improved. Based on the target proportional-integral control strategy, the proportional-integral adjusting torque of the motor is determined, and the idle speed control requirements of the engine under various idle speed working conditions can be effectively met; meanwhile, on the basis of proportional-integral adjustment, torque compensation of the motor can be achieved in combination with the current rotating speed difference of the engine, then the first motor execution torque of the motor is determined on the basis of proportional-integral adjustment torque and compensation torque, the motor is controlled to output torque according to the first motor execution torque, and the rapid response characteristic of the motor is used for adjusting the torque. And the idle speed of the engine can be quickly and stably controlled.
