Patent ID: 7654374

Claim:
An automated transmission controller, comprising: a friction clutch; a dog-clutch-type transmission having a plurality of first gears on which engaging projections are formed and a plurality of second gears on which engaging concaves engaging with the engaging projections are formed, the engaging projections of the first gears engaging with the corresponding engaging concaves of the second gears to effect a change in gear ratios in the dog-clutch-type transmission; an automated transmission unit having an electrically powered actuator configured to conduct connection and disconnection of the friction clutch, the automated transmission unit also being configured to conduct gear ratio changes of the dog-clutch-type transmission; a control unit configured to control the operation of the actuator; a gear position sensor configured to detect the gear position of the dog-clutch-type transmission; wherein the control unit is configured to perform gear change assist control under which, at the time of shift change, the clutch position of the friction clutch is shifted to the connection side at a first connection speed and a second connection speed, wherein the first connection speed is lower than the second connection speed, the control unit being configured to shift the clutch position toward the connection side, at the second speed, between a second clutch position where the friction clutch is in a completely disconnected condition and a reference clutch position which is located on the disconnection side from a first clutch position where the half-clutch condition ends, the control unit also being configured to shift the clutch position toward the connection side at the first speed during a period from the time when the clutch position reaches the reference clutch position until the time when engagement condition between the engaging projections and the engaging concaves is detected by the gear position sensor; and wherein the control unit is configured to shift the position of the friction clutch to the disconnection side after when the engagement condition is detected.
