Abstract
An electronic control unit executes gradual reduction control when a friction clutch is to be maintained in a fully engaged state such that an input rotary member and an output rotary member rotate integrally. As a result, a motor current supplied to a motor is adjusted to a lower current value. Thus, an average current value of the motor current supplied to the motor when the friction clutch is to be maintained in the fully engaged state is appropriately reduced.
