Control device and control method for dual clutch transmission

A control method for a dual clutch transmission that is provided with a clutch device including a first clutch and a second clutch between a drive source and a transmission mechanism and is configured to switch a torque transmission path from the transmission mechanism to a vehicle drive system into two lines, the control method comprising:

• performing a clutch switching control comprising, when a vehicle stops during performing of a creep control comprising bringing one of the first clutch and the second clutch into a half-clutch state and bringing the other of the first clutch and the second clutch into a disengaged state so as to transmit a predetermined torque from the drive source to the transmission mechanism via the clutch device, on the basis of a heat-generating state of the one clutch that is maintained in the half-clutch state from the stop of the vehicle, switching the one clutch from the half-clutch state to the disengaged state and switching the other clutch from the disengaged state to the half-clutch state.
