Abstract
When a driver performs a steering operation with a small steering angle when a vehicle is stopped, a viscous clutch of a viscous heater is turned on after setting an idling rotational speed of an engine to a high value to prevent an engine stall. Further, when a driver performs the steering operation with a large steering angle when the vehicle is stopped, the viscous clutch is not turned on so that the viscous heater is not operated, thereby greatly reducing a driving load applied to the engine and a V-belt thereof.
