Abstract
A controller, control method, and control system for a motor vehicle gear-type transmission enable a friction transmission unit to be controlled to an optimum position according to a particular motor vehicle state or the like. A transmission control unit changes, via at least one parameter that indicates a state of the gear-type transmission or of the vehicle, a position or pressure load at which the pressure member is caused to stand by while the driving shaft of the vehicle is in a stopped state or during changeover of the mesh unit that connects to one of the gear pairs.
