The invention discloses a vehicle cooling system control method. According main points of the design concept of the invention, after a vehicle cooling machine is started, the water temperature and the heating requirement of a small cycle are detected, and a gearbox branch is triggered to be connected or disconnected according to a relation between the water temperature and a threshold value; and according to a heating requirement, a warm air water tank branch is triggered to be connected or disconnected. According to the invention, the control mode of a traditional cooling system is optimized and improved, and particularly, a gearbox and warm air branch circulation scheme during cold start is specifically designed, so the temperature rise of an engine can be accelerated to reduce the heat loss of the engine; and through fine control of the gearbox branch, the problem that the temperature rise of a gearbox is slow due to starting lag of a wax type thermostat is effectively solved, so the temperature rise performance of a traditional vehicle power assembly in a warm-up process is improved, and obvious contributions are made to vehicle oil saving and emission.

    本发明公开了一种车辆冷却系统控制方法,本发明的主要设计构思在于,在车辆冷机启动后检测小循环的水温及采暖需求,并根据水温与阈值的关系,触发变速箱支路导通或切断;以及,根据采暖需求,触发暖风水箱支路导通或切断。本发明对传统冷却系统的控制方式进行了优化改进,尤其是针对冷启动时的变速箱及暖风支路循环方案进行具体设计,从而可以加快发动机的温升以减少发动机的热损失;通过变速箱支路精细化控制,有效解决了蜡式节温器开启滞后所导致的变速箱温升慢的问题,从而改善传统车辆动力总成暖机过程的温升性能,对车辆节油和排放都作出了显著贡献。
