Abstract
In a power transmission device in which a first power transmission path is formed by engagement of a first clutch and a dog clutch and a second power transmission path is formed by engagement of a second clutch, the first clutch is released from a state where the first clutch and the dog clutch are engaged, and when a front-rear rotation speed difference of the dog clutch becomes equal to or greater than a predetermined value after the start of a clutch-to-clutch gear shift for engaging the second clutch, complete release control for releasing the first clutch to lower the torque capacity of the first clutch is performed.
