The invention discloses a thermal management system control method, a thermal management system, a vehicle and a storage medium, and belongs to the technical field of vehicles. According to the thermal management system control method, the thermal management system, the vehicle and the storage medium, when the thermal management system is controlled to switch the working mode, the target state of each part of the refrigerant circulation unit is determined firstly, and then the control priority of each part of the refrigerant circulation unit is determined according to the determined target state; the starting priorities of the control valve group and the expansion valve are both higher than the starting priority of the compressor, in the same refrigerant circulation loop, the closing priorities of the control valve group and the expansion valve are the lowest, and then all the parts are controlled to be switched to the determined target state according to the control priorities, so that the situation that the compressor is started firstly, and then the compressor is stopped is avoided. The high pressure of the refrigerant circulation loop is too high due to the fact that the control valve set is opened again, and the situation that the low pressure of the refrigerant circulation loop is too low due to the fact that the compressor is opened firstly and then the expansion valve is opened can be avoided.

    本发明公开了一种热管理系统控制方法、热管理系统、车辆及存储介质,属于车辆技术领域。本发明的热管理系统控制方法、热管理系统、车辆及存储介质,在控制热管理系统切换工作模式时,先确定制冷剂循环单元的各个零部件的目标状态,再根据所确定的目标状态,确定制冷剂循环单元的各个零部件的控制优先级,并使控制阀组和膨胀阀的启动优先级均高于压缩机的启动优先级,且在同一制冷剂循环回路中,控制阀组和膨胀阀的关闭优先级最低,再根据控制优先级,控制各个零部件切换至所确定的目标状态,可避免先开启压缩机,再开启控制阀组而导致制冷剂循环回路的高压压力过高,并可避免先开启压缩机,再开启膨胀阀而导致制冷剂循环回路的低压压力过低。
