Abstract
In one embodiment, when a switching clutch or a switching brake is engaged and thus a differential of a differential unit is limited, the gear ratio of a continuously variable transmission unit is adjusted. On the other hand, when the switching clutch and the switching brake are both released and thus the differential of the differential unit is not limited, an overall gear ratio obtained from the gear ratio of the differential unit and the gear ratio of the continuously variable transmission unit is adjusted.
