DEVICE FOR CONTROLLING POWER TRANSMISSION OF VEHICLE

This power transmission control device is applied to a hybrid vehicle which includes an internal combustion engine and a motor (MG) as power sources. The power transmission control device includes a manual transmission and a friction clutch. When a clutch enters a completely disengaged state (t2) as a result of operation of a clutch pedal by a driver in a state where MG torque is adjusted to regeneration torque acting in a direction for decelerating the vehicle, the magnitude of the regeneration torque is decreased to "minute value A which is greater than zero," and then maintained at the minute value A. Much energy generated as a result of regeneration can be stored in a battery (see the area shown by dots) as compared with the case where the regeneration torque is adjusted to zero immediately after the clutch enters the completely disengaged state. Accordingly, energy efficiency (fuel efficiency) is improved.
