Actual-rotational-difference absorption-torque calculation means 150 inputs a rate-of-change ΔNe of an engine speed during shifting to an actual rotational difference absorption torque-ΔNe table 160 so that an actual-rotational-difference absorption-torque average value during shifting is calculated. Engine-torque calculation means 180 inputs a throttle opening and an engine speed to engine-torque estimation-value map 190, and derives an engine torque during shifting. An actual clutch capacity is calculated from the sum of the actual-rotational-difference absorption-torque average value and the engine torque average value during shifting. From the ratio of the actual clutch capacity and a demanded clutch capacity, μ-correction-coefficient calculation means 130 calculates a μ correction coefficient. By using a control correction amount calculated on the basis of the μ correction coefficient, a transmission control unit 100 drive-controls a first clutch CL1 and a second clutch CL2. Thus, correction on the clutch capacity is performed during running.
