PURPOSE: To prevent an engaging chock and blow-up of an engine caused by as excess and deficiency of control current resulting from the fact that relation is not appropriate by using previously stored relation between the operation position of an automatic clutch and the load torque of a driving motor in such a case where the control current at the time of performing feedback control is determined so as to force the operation position of the clutch to follow a target position by a driving motor.
CONSTITUTION: When it is detected that the condition that the gear stage of a stepped transmission 16 is in a neutral condition and that car speed is not more than 5km/h is surely realized in a step ST11, a clutch 14 is operated from an engaging position to a releasing position and from the releasing position to the engaging position while successively increasing motor load torque as a parameter for learning to store the motor load torque when a driving motor 42 moved in a step ST14, thereby the map of the operation position of the clutch and the motor load torque is renewed.
