The invention discloses a vehicle thermal management system control method, a vehicle thermal management system and a vehicle, the method is applied to the vehicle thermal management system, and the vehicle thermal management system comprises an air source heat pump heating loop, a battery heating branch and a communication branch used for communicating the air source heat pump heating loop with the battery heating branch. The control method comprises the steps that whether the vehicle heat management system is switched to an air source heat pump heating working mode corresponding to an air source heat pump heating loop or not is judged; and if yes, the communication branch is opened, so that the refrigerant in the battery heating branch is conveyed into the air source heat pump heating loop. According to the technical scheme, the battery heating branch is used for supplementing the refrigerant for the air source heat pump heating loop, so that the problem that the refrigerant of the air source heat pump heating loop is insufficient is solved, the heating effect of a passenger compartment is guaranteed, and due to the fact that an additional refrigerant supplementing device does not need to be arranged, the heating efficiency is improved. The heating cost of a passenger compartment and the complexity of a vehicle heat management system can be reduced.
本发明公开了一种车辆热管理系统控制方法、车辆热管理系统及车辆,方法应用于车辆热管理系统中,车辆热管理系统包括空气源热泵采暖回路、电池加热支路、用于连通空气源热泵采暖回路及电池加热支路的连通支路,控制方法包括:判断车辆热管理系统是否切至空气源热泵采暖回路对应的空气源热泵采暖工作模式;若是,则开启连通支路,以将电池加热支路中的冷媒输送至空气源热泵采暖回路中。本发明公开的技术方案,利用电池加热支路为空气源热泵采暖回路补充冷媒,以解决空气源热泵采暖回路冷媒不足的问题,保证乘员舱采暖效果,且由于并不需要设置额外的补冷媒装置,因此,可降低乘员舱采暖成本以及车辆热管理系统的复杂度。
