Abstract
According to the present invention, when an air-conditioning clutch of a compressor is set on, even if an improvement of a heating capacity by a viscous heater is required, a viscous clutch is turned off not to transmit a rotational driving force of an engine to a rotor of the viscous heater, and further the rotational driving force of the engine is transmitted to the compressor. In this way, a torque applied to the engine E and the V-belt can be reduced, so that a fuel consumption ratio of the engine lowers and a fuel economical performance improves. Further, because an operation of the compressor is intermitted, it is possible to remove a fog of a front windshield, so that a safety of the vehicle travelling can be prevented from being deteriorated.
