Abstract
The invention relates to a control device ( ) for an automatically and manually shiftable gearbox in a motor vehicle. The inventive control device comprises a selector lever ( ) for adjusting at least the forward position (D), neutral (N), reverse (R), parking position (P) and a position (M) for manual shifting. A first and a second tip switch ( ) can be actuated in the position (M) for manual shifting. Signals for manually shifting up or down with regard to the gear ratio are supplied to a control device ( ) for controlling the gearbox by means of position sensors ( ) and control lines ( ). Failure of the position sensors ( ) and/or the control lines ( ) that are allocated to said sensors can be detected. The control device is improved by configuring said control device ( ), with regard to shifting, in such a way that all the position sensors ( ) can be checked and the failure of a position sensor ( ) and/or a control line ( ) can be detected at least in the parking position (P) or reverse (R) position of the selector lever ( ).
