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.

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

A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a select or finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.

Hill holder device for a motor vehicle

A method of regulating the position of a clutch actuator in a vehicle employs the concept of adapting the servo-loop parameters of a position controller of the clutch to different operating conditions of the vehicle, as well as the concept of applying and continuously adapting a bias current of the actuator motor in order to avoid or minimize the incidence of a hunting or after-regulation behavior of the control loop and to thereby minimize the energy consumption of the actuator motor.
