Description

Vehicle heating method and device, vehicle and storage medium Technical Field The invention relates to the technical field of automatic control, in particular to a heat supply method and device for a vehicle, the vehicle and a storage medium. Background In a traditional internal combustion engine vehicle, cabin heating is realized by a warm air water tank after the temperature of engine cooling liquid rises, and the heat source of the cabin heating is completely derived from the waste heat of an engine body. Under low temperature environment, the effective working temperature can be reached only after the engine is started in a cold mode, so that the warm air system can not provide comfortable temperature in time, and the experience of passengers is seriously reduced. Especially in winter or alpine regions, there is a strong demand for rapid cabin temperature rise by users, and it is expected that effective hot air can be obtained within seconds after the vehicle is started, so as to improve riding comfort and safety. However, the current mainstream automobile heating systems all adopt a single heat source and a passive heat conduction mode, and the warm air output and the engine warming process are deeply coupled, so that the independent control and energy transfer of the heat source cannot be realized. In the prior art, although the scheme of utilizing the exhaust waste heat for auxiliary heating exists, the scheme is still limited by inherent defects of delayed thermal response and non-storable energy, namely, the exhaust temperature is low in the initial stage of cold start, the heat output is insufficient, a heat storage unit is lacked in a system, and the surplus waste heat cannot be collected and stored for later use in the heating process of an engine, so that the heat energy utilization rate is low and the heating persistence is poor. Therefore, the prior art cannot meet the core requirement of 'instant heating' in the cold start stage, and has a significant problem of thermal response delay.
