Patent ID: 8216110

Claim:
A shifting control system comprising: a first gear shift stage group including a plurality of gear shift stages; a second gear shift stage group including a plurality of gear shift stages; a first clutch operatively coupled to the first gear shift stage group to selectively transmit power from an engine to a wheel; a second clutch operatively coupled to the second gear shift stage group to selectively transmit power from the engine to the wheel; a clutch release detection section configured to detect a release-side clutch which corresponds to one of the first and second clutches that is in a released state; a pre-shift controller arranged to operate a meshing mechanism of one of the first and second gear shift stage groups, which is to be connected to the engine by the release-side clutch, so as to undergo pre-shifting when the other of the first and second clutches is engaged as an engage-side clutch; a clutch oil level detection section configured to determine whether an oil level in the release-side clutch is equal to or greater than a preset oil level; and a pre-shift inhibiting section configured to inhibit pre-shifting while the oil level in the release-side clutch is equal to or greater than a preset oil level.
