Beschreibung
Zusammenfassung:	The invention relates to a fan clutch control technology, in particular to a control method for reducing suction noise of a fan clutch, which is realized through a vehicle-mounted control unit or additional computing equipment, and mainly comprises the steps of acquiring real-time rotating speed of an engine, computing driving rotating speed, acquiring real-time rotating speed and inflection point current of fan blades, and determining inflection point voltage. And the power supply voltage of the fan clutch is gradually increased to full-voltage power supply according to the parameters. The open-loop control strategy and the closed-loop control strategy are adopted, PID algorithm control based on the rotating speed and the rotating speed rate is included, the suction process of the fan clutch is smoothed, abrasion is reduced, noise is lowered, the energy efficiency and the driving comfort are improved, and meanwhile the service life of the fan clutch is prolonged. In addition, maintenance is simplified, the s
