Abstract: A method is provided for controlling an external control type fan clutch. The method controls the On/Off of an electromagnet-activated valve for an oil feed adjusting hole. The method uses a PID control on the basis of radiator cooling liquid temperature, fan speed, transmission oil temperature, vehicle speed, engine speed, compressor pressure of an air conditioner, and an On/Off signal of the air conditioner. Individual gains of the PID control are determined by a gain matrix containing the optimum fan speed demanded by the engine, the actual metered fan speed, and the engine speed. The PID control is made on the basis of the gains to that a control signal is outputted. The control method can improve mileage, raise the cooling efficiency of an air conditioner and suppress fan noise.

Abstract: An outside control type fan coupling apparatus has a double valve structure with plural oil supply adjustment holes. Temperature of engine coolant, acceleration of the engine, an air conditioner, vehicle speed and so on are parameters for controlling opening and closing valves of the oil supply adjustment holes.

Also, if engine rotation accelerates to more than a certain level, the fan coupling apparatus is turned Off, and fan noise due to coupling rotation is prevented. Further, if engine rotation is less than a constant rotational speed, the fan coupling apparatus is turned Off, Middle, and fan noise due to coupling rotation of the fan at the time of acceleration and fan noise due to coupling rotation at the time of startup of the engine are prevented.
