Abstract: In a vehicle power transmission device equipped with an automatic clutch, the gear-change for shifting up is effected suppressing a sudden increase in the engine rotational speed that results when the automatic clutch is disconnected, preventing deterioration in the drive feeling caused by the change of gear such as a shock due to the change of gear. At the time of changing the gear for shifting up, an engine controller (11) executes a pre-reduction control for decreasing the output of the engine 1 for a predetermined period of time prior to disconnecting the clutch (3). Since the engine output has been decreased, the rotational speed of the engine (1) does not suddenly rise despite the vehicle traveling load is removed as a result of disconnecting the clutch 3.

By this constitution, the direction of the driving force can be quickly reversed.

Abstract: Clutch disengagement shock resulting from the sudden release of torsional torque is prevented and ride-feeling at the time of changing gears or starting at a low-speed gear stage in an automatic clutch vehicle is improved. In a clutch control arrangement for controlling the engagement and disengagement of a friction-type clutch (1) by means of a clutch actuator (3) and a control unit (14), clutch disengagement speed is reduced when, at least, a gear-changing operation by a driver is detected, and the transmission (20) is in a low-speed gear stage. Even when the clutch is automatically disengaged at gear change, since disengagement speed is reduced if the current gear stage is a low-speed gear stage, the clutch (1) is not abruptly disengaged, enabling the prevention of clutch disengagement shock due to the sudden release of torsional torque.
