Patent ID: 7507182

Claim:
A controller for a motor vehicle gear-type transmission which comprising: a friction transmission mechanism which transmits power by adjusting a pressure member that applies a pressure to a friction surface; an input shaft which rotates by receiving the torque transmitted from the friction transmission mechanism; an output shaft which outputs torque to a driving shaft of a motor vehicle; a plurality of gear pairs each rotating between the input shaft and the output shaft; a plurality of mesh mechanisms each establishing a required change gear position by connecting any one of the plural gear pairs to the input shaft or the output shaft; and an actuator which adjusts the position or pressure load of the pressure member; wherein the controller includes a control apparatus that is configured to change, by using at least one parameter indicating a state of the gear-type transmission or of the vehicle, a position at which the pressure member is caused to stand by while the driving shaft is in a stopped state or during changeover of any one of the mesh mechanisms that connects to any one of the gear pairs; wherein the change is carried out prior to a driver's operation of start or acceleration; and wherein the stand by is within an open state in which the friction transmission mechanism does not transmit the power.
