A method for compensating roadway changes in a transmission control system of an automatic vehicle transmission, according to which each change in the roadway is recognized and compensated. Also disclosed is a transmission control system of an automatic vehicle transmission, particularly for carrying out the inventive method, comprising at least one device for detecting and compensating changes in the roadway.

Transmission control system and method for compensating plant changes in a transmission control system of an automatic vehicle transmission

Specific shift positions of an electrically actuated vehicle transmission, such as first to fifth, neutral and reverse gears, are detected by monitoring one or more characteristic electrical variables, e.g., actuator currents, during a shift movement of the transmission and by correlating increased or decreased levels of current with the arrival at or passage through the specific shift positions.

Method of operating a vehicle transmission

A motor vehicle transmission is shiftable in a track pattern with a selector track and shift tracks. A shifter element moves along the tracks when the transmission is shifted from one gear ratio to another. The shifts are directed by a control device sending command signals to an actuator device which, in turn, applies an actuating force to the transmission. A main position-detecting device detects the position of the shifter element relative to the selector track and shift tracks, and a redundant position-detecting device performs an additional, redundant determination of the shifter-element position.
