A control apparatus for a drive-force transmitting apparatus that defines a first drive-force transmitting path that is to be established by engagements of a first frictional engagement device and a dog clutch and a second drive-force transmitting path in which a lower gear ratio is provided than in the first drive-force transmitting path. In a second running mode with the second drive-force transmitting path being established, the control apparatus places the dog clutch in a released state when a vehicle running speed is higher than a first speed value, and places the dog clutch in an engaged state when the running speed is not higher than the first speed value. Further, in the second running mode, the control apparatus inhibits the dog clutch from being switched to the released state when an accumulated heat quantity in a synchromesh mechanism of the dog clutch is larger than a first quantity value.
