The invention provides a fan control method and system for a vehicle and the vehicle, and relates to the field of vehicle cooling. The method comprises the following steps that firstly, after the vehicle is powered on, the water temperature of each cooling loop in the vehicle and the temperature of each part in each cooling loop are acquired in real time; then when the water temperature of the cooling loops is higher than first preset temperature, first output needs, corresponding to each fan, of the water temperature of the cooling loops is found from a preset storage module, and when temperature of the parts is higher than second preset temperature, second output needs, corresponding to each fan, of the temperature of the parts is found from preset storage module ; and finally, the maximum value in all the first output needs and the second output needs is selected to control each fan, so that the cooling needs of all the cooling loops are met at the same time. The cooling needs of each cooling loop and each part in each cooling loop in the vehicle can be comprehensively considered, and the cooling needs of all the cooling loops can be met at the same time.
本发明提供了一种用于车辆的风扇控制方法、控制系统及车辆,涉及车辆冷却领域。本发明先在车辆上电后实时地获取车辆中每一冷却回路的水温和每一冷却回路中各个部件的温度;然后在冷却回路的水温高于第一预设温度时从预置存储模块中查找得到冷却回路的水温对应于每一风扇的第一输出需求以及在部件的温度高于第二预设温度时从预置存储模块中查找得到部件的温度对应于每一风扇的第二输出需求;最后选择所有第一输出需求和第二输出需求中的最大值对每一风扇进行控制,以同时满足所有冷却回路的冷却需求。本发明能够综合考虑到车辆中每一冷却回路和每一冷却回路中各个部件的冷却需求,可以同时满足所有冷却回路的冷却需求。
