The invention provides a rotating speed control method and device for a vehicle-mounted silicone oil fan and a vehicle, and the method comprises the steps that a target first rotating speed and a target second rotating speed are obtained, the target first rotating speed is the first rotating speed at the current moment, the first rotating speed is the rotating speed of a transmitter, and the target second rotating speed is the second rotating speed at the current moment; the second rotating speed is the set rotating speed of the vehicle-mounted silicone oil fan; under the condition that the target first rotating speed is smaller than the first threshold value, the target second rotating speed is reduced to keep the first rotating speed deviation larger than the second threshold value, and the first rotating speed deviation is the difference value between the target first rotating speed and the target second rotating speed; and under the condition that the target first rotating speed is larger than or equal to the first threshold value, the target second rotating speed is controlled to be kept unchanged. The problem that in the prior art, when an engine is in an idling or low-speed state, a silicone oil fan is prone to full speed, and consequently fan rotating speed control delay is long is solved.

    本申请提供了一种车载硅油风扇的转速控制方法、转速控制装置和车辆,该方法包括:获取目标第一转速和目标第二转速,目标第一转速为当前时刻的第一转速,第一转速为发送机的转速,目标第二转速为当前时刻的第二转速,第二转速为车载硅油风扇的设定转速;在目标第一转速小于第一阈值的情况下,降低目标第二转速以保持第一转速偏差大于第二阈值,第一转速偏差为目标第一转速与目标第二转速的差值;在目标第一转速大于或等于第一阈值的情况下,控制目标第二转速保持不变。解决了现有技术中发动机怠速或低速状态下,硅油风扇容易全速导致进行风扇转速控制延迟较长的问题。
