    摘要: When a gear position at a higher speed range than a "specific gear position at a lower speed range" (e.g., first speed) is determined (when the torsional vibration is difficult to occur), a clutch torque is controlled such that a clutch is in a totally engagement state (a revolution speed Ne of an output shaft of an engine = revolution speed Ni of an input shaft of a transmission). On the other hand, when the "specific gear position at the lower speed range" (e.g., first speed) is determined (when the torsional vibration is easy to occur), the clutch torque is controlled such that the clutch is in the semi-engagement state (Ne ― Ni = predetermined positive value A). In the semi-engagement state, a "damping action by a slip on the clutch" is acted on the torsional vibration, whereby the amplitude of the torsional vibration can be reduced.
