The invention relates to the technical field of vehicles, and provides a vehicle heating method and device, a vehicle control unit and a storage medium, and the method comprises the steps that in response to an instruction that a heat pump system of a vehicle enters a heating mode, control parameters of the heat pump system are obtained; according to the control parameters of the heat pump system, whether the heat pump system is in a small-load working condition is determined; under the small-load working condition, heat output by the heat pump system is larger than or equal to the heat requirement in the vehicle; in response to the fact that the heat pump system is in the small-load working condition, the rotating speed of a compressor of the heat pump system is determined according to the actual air outlet temperature of the heat pump system and the target air outlet temperature of the heat pump system; and controlling a compressor of the heat pump system by using the rotating speed. The accuracy and efficiency of vehicle heating can be improved.
