The invention relates to the technical field of automobile engines, and discloses a fan rotating speed control method, a vehicle-mounted air conditioning system and a vehicle. The fan rotating speed control method comprises the steps of obtaining air conditioner air volume information; obtaining the optimal rotating speed information of a fan according to the air conditioner air volume information; and controlling the fan to operate according to the optimal rotating speed information of the fan. According to the fan rotating speed control method, after an air conditioner switch is turned on, the air conditioner air volume information is obtained firstly, then the optimal fan rotating speed information matching the fan air volume information is obtained, and then the fan is controlled to operate according to the obtained optimal fan rotating speed information. By means of the arrangement mode, the fan can operate at the optimal rotating speed, the time for the fan to be in the direct connection state is shortened, and therefore the performance of an engine is improved, and oil consumption is reduced.

    本发明涉及汽车发动机技术领域,公开了一种风扇转速控制方法、车载空调系统及车辆,该风扇转速控制方法包括:获得空调风量信息;根据空调风量信息得到风扇最优转速信息;根据风扇最优转速信息控制风扇运行。本发明提供的风扇转速控制方法,当空调开关开启后,先获得空调风量信息,然后获取与风扇风量信息匹配的风扇最优转速信息,接着控制风扇以获取到的风扇最优转速信息运行。这种设置方式,风扇能够以最优转速运行,降低了风扇处于直连状态的时间,从而提升发动机的性能,且降低了油耗。
