The invention relates to a cab heating system, a control method thereof and a vehicle heat management system. The cab heating system comprises a cab heating assembly, a heat exchange assembly, a temperature sensor and a control unit. The heat exchange assembly comprises a first branch and a first valve, the first branch is connected to a cooling liquid outlet and a cooling liquid inlet of the fuel cell heat management system, the first valve controls on-off of the first branch, and the heat exchanger is connected into the first branch and the cab heating loop. The control unit controls the heating element and the first valve according to the liquid temperature value, detected by the temperature sensor, of the cooling liquid. When the cab heating system is in the first state, the first valve is opened, the cooling liquid in the first branch and the heat exchange medium in the cab heating loop are subjected to heat exchange through the heat exchanger, heat of the cooling liquid is used for supplying heat to a cab, the heating element stops heating at the moment, and the working time of the heating element is shortened; the heating energy consumption of the cab is reduced.

    本申请涉及一种驾驶室采暖系统及其控制方法、车辆热管理系统,其中驾驶室采暖系统包括驾驶室采暖组件、换热组件、温度传感器和控制单元。换热组件包括第一支路及第一阀门,第一支路连接于燃料电池热管理系统的冷却液出口和冷却液进口,并由第一阀门控制通断,换热器接入第一支路和驾驶室采暖回路。控制单元根据温度传感器检测的冷却液的液温值控制加热元件和第一阀门。当驾驶室采暖系统处于第一状态时,第一阀门开启,通过换热器使第一支路中的冷却液和驾驶室采暖回路中的换热介质进行热交换,利用冷却液的热量为驾驶室供暖,且此时加热元件停止加热,使加热元件的工作时间减少,驾驶室的采暖能耗降低。
