PROBLEM TO BE SOLVED: To reduce or prevent the damage of a clutch when a creep process is effected, in a control device for a transmission system in the drive train of a vehicle. SOLUTION: A control unit controls a creep process when, in a transmission, a gear is not engaged, a brake is not operated, a load lever is not operated, and an engine is during running. During engagement of a clutch, torque transmitted by a clutch is controlled from a first value MK1 to a section value MKriech like creep torque. In this case, a vehicle is progressed in a creeping state. The value of creep torque MKriech is selected depending upon a clutch temperature.
