Method and device for controlling gear ratio change in a transmission contained in the drive train of a motor vehicle with gears that can be shifted under power

Patent number: 7510506

Abstract: In a parallel manual transmission, an upshifting under power is executed based upon preset operating conditions, for example with a fully depressed accelerator pedal, without an electronically controlled, load-reducing ignition retard. When shifting to a higher gear, the engine output is used for increasing the speed of the engine and for the propulsion of the vehicle, based upon the operating condition of the drive train.
