Abstract:
A shift-by-wire control unit is provided that includes, but is not limited to a sensor for detecting the position of a shift lever, which is movable on a path between a neutral position and at least one shift position, a control circuit, and an actuator for driving a selector fork in accordance with a movement of the shift lever detected by the control unit. The control circuit is set up to predefine a setpoint position of the actuator for each detected position of the shift lever, the rate of change of the setpoint position as a function of the shift lever position being higher in a first area of the path adjacent to the neutral position than in a second area of the path, which is at a greater distance from the neutral position than the first area.
