The invention provides a vehicle heat management method and device. The method comprises the steps that the working mode of a vehicle air conditioning system is recognized; determining a mode dead zone and a valve control scheme based on the working mode; the valve control scheme is adjusted based on the mode dead zone, and a heat management control scheme is obtained; and controlling the vehicle air conditioning system to work based on the thermal management control scheme. Therefore, according to the method and the device, the redundant refrigerant can be stored in the dead zone, so that the effects of reducing the cost and balancing the refrigerant charge quantity in different modes are achieved, the charge quantity compatibility problem of the air conditioning system in different modes is solved, and the refrigerating and heating performance of the system is optimized.

    本申请提供一种车辆热管理方法及装置,该方法包括:识别车辆空调系统的工作模式;基于工作模式,确定模式死区和阀门控制方案;基于模式死区对阀门控制方案进行调整,得到热管理控制方案;基于热管理控制方案控制车辆空调系统进行工作。可见,该方法及装置能够利用死区储存多余的冷媒,从而实现降低成本、平衡不同模式冷媒充注量的效果,进而解决空调系统不同模式的充注量兼容问题,使得系统制冷制热性能得到优化。
