Abstract:
1. A method of reducing at least one of a contact speed and a transmitting torque between power transmission members, when a slack between the power transmission members in a power transmission path from a drive source to a wheel is apparently gone upon an acceleration or deceleration of the drive source or the wheel, the method comprising the steps of: detecting an information relating to a rotational speed of an input shaft of a controlled section in the power transmission path, the controlled section being defined as to be reduced in the at least one of the contact speed and the transmitting torque; calculating a relative rotational position between the input shaft and an output shaft of the controlled section based on the detected information relating to the rotational speed of the input shaft; and accelerating or decelerating at least one of the input shaft and the output shaft so as to reduce the at least one of the contact speed and the transmitting torque between the power transmission members based on the calculated relative rotational position.
