The invention belongs to the field of automobiles, and particularly relates to a degassing method and a vehicle thermal management system. The invention provides a degassing method for a vehicle thermal management system, the vehicle thermal management system comprises an auxiliary water tank, a first circulation loop and a second circulation loop, the first circulation loop is communicated with the auxiliary water tank, and the second circulation loop is arranged to be selectively communicated with or disconnected from the first circulation loop. The degassing method comprises the steps that it is determined that the vehicle thermal management system is in a degassing mode, and a first circulation loop and a second circulation loop are controlled to be disconnected; a heat exchange medium in the auxiliary water tank is controlled to pass through a first circulation loop for first-stage exhaust; after it is determined that first-stage exhaust is completed, the first circulation loop and the second circulation loop are controlled to communicate; and the heat exchange medium in the auxiliary water tank is controlled to pass through the second circulation loop for second-stage exhaust. Through a two-stage exhaust mode, the exhaust difficulty is reduced, the exhaust effect is guaranteed, and normal work of the vehicle thermal management system is guaranteed.

    本发明属于汽车领域,尤其是涉及一种除气方法及车辆热管理系统。本发明第一方面提供了一种用于车辆热管理系统的除气方法,车辆热管理系统包括副水箱、第一循环回路及第二循环回路,第一循环回路连通副水箱,第二循环回路被设置成和第一循环回路可选择性地连通或断开。除气方法包括:确定车辆热管理系统在除气模式下,控制第一循环回路和第二循环回路断开;控制副水箱中的热交换介质经由第一循环回路,以进行第一阶段排气;确定第一阶段排气完成后,控制第一循环回路和第二循环回路连通;控制副水箱中的热交换介质通过第二循环回路,以进行第二阶段排气。通过两阶段排气的方式,降低排气难度,保证排气效果,保证车辆热管理系统正常工作。
