The invention provides a control method, device and equipment of a vehicle heating system, a vehicle and a storage medium, and belongs to the technical field of vehicles. The method comprises the steps that the environment temperature, passenger compartment data, the upstream pressure of a first electronic expansion valve and the suction pressure of a second electronic expansion valve are obtained in real time; a heat pump, an internal heat exchanger, an external heat exchanger and an electromagnetic switch are started, a first electronic expansion valve is started according to the first initial opening degree, and a second electronic expansion valve is started according to the second initial opening degree; the first electronic expansion valve is automatically controlled according to the upstream pressure and the preset target upstream pressure, so that the opening degree of the first electronic expansion valve is automatically changed along with the change of the upstream pressure according to a first preset corresponding relation; and the second electronic expansion valve is automatically controlled according to the suction pressure and the preset target suction pressure, so that the opening degree of the second electronic expansion valve is automatically changed along with the change of the suction pressure according to a second preset corresponding relation. The cost of the whole vehicle can be reduced.
本申请提供一种车辆加热系统的控制方法、装置、设备、车辆及存储介质,属于车辆的技术领域。该方法包括:实时获取环境温度、乘员舱数据、第一电子膨胀阀的阀前压力和第二电子膨胀阀的吸气压力;启动热泵、内部换热器、外部换热器和电磁开关,并按第一初始开度启动第一电子膨胀阀,以及按第二初始开度启动第二电子膨胀阀;根据阀前压力和预设目标阀前压力对第一电子膨胀阀进行自动控制,使得第一电子膨胀阀的开度按第一预设对应关系随阀前压力的变化而自动改变;根据吸气压力与预设目标吸气压力对第二电子膨胀阀进行自动控制,使得第二电子膨胀阀的开度按第二预设对应关系随吸气压力的变化而自动改变。本申请能降低车辆的整车成本。
