Abstract
Effects caused by unevenness among drive power sources and transmission torque changing apparatus and aging effects in a vehicle transmission are controlled without using sensors. A power train control unit releases engine torque through an assist clutch to release at least a part of gear train transmission torque to shift a meshing clutch toward a release position. During the gear release, a load is applied in a direction in which the meshing clutch is shifted toward the release position, before the transmission torque of the gear train is completely released, and the meshing clutch is shifted to the release position when at least a part of the transmission torque of the gear trains is released.
