Abstract

A method for operating a motor vehicle, for which it is monitored whether a communication failure is present between a transmission control instrument of an automatic transmission of the motor vehicle, a selector lever control instrument of the automatic transmission, and/or a parking brake control instrument of an electronic parking brake of the motor vehicle, and/or whether, on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of a selector lever itself for selection of drive stages of the automatic transmission, a parking position of the automatic transmission cannot be engaged.

First claim

1 - 10 . (canceled)

11 . A method for operating a motor vehicle, comprising:
monitoring whether a communication failure is present between a transmission control instrument of an automatic transmission of the motor vehicle, a selector lever control instrument of the automatic transmission, and/or a parking brake control instrument of an electronic parking brake of the motor vehicle; and/or monitoring whether, on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of a selector lever itself for selection of drive stages of the automatic transmission, a parking position of the automatic transmission cannot be engaged; operation of the transmission control instrument, of the parking brake control instrument and of a display control instrument of a display device of the motor vehicle depending on the monitored control instruments between which a communication failure has been detected, and/or whether the parking position cannot be engaged on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of the selector lever itself.

12 . The method according to claim 11 , wherein the display control instrument actuates the display device for display of a warning message, by which it is signaled that the driver should engage the parking position in the automatic transmission if it is detected that a communication failure is present in the parking brake control instrument.

13 . The method according to claim 11 , wherein the display control instrument actuates the display device for display of a warning message, by which it is signaled that the driver should engage the electronic parking brake if it is detected that a communication failure is present in the transmission control instrument and/or in the selector lever control instrument.

14 . The method according to claim 11 , wherein the display control instrument actuates the display device for display of a warning message, by which it is signaled that the driver should take safety measures differing from an actuation of the electronic parking brake and from an actuation of the automatic transmission if it is detected that a communication failure is present in the parking brake control instrument and in the transmission control instrument.

15 . The method according to claim 11 , wherein the display control instrument actuates the display device for display of a warning message, by which it is signaled that the driver should park the motor vehicle if it is detected that a communication failure is present for at least one of the monitored control instruments.

16 . The method according to claim 12 , wherein the display control instrument actuates the display device for display of the warning message only when it has been detected that an ignition of the motor vehicle has been deactivated.

17 . The method according to claim 11 , wherein the transmission control instrument automatically engages the parking position of the automatic transmission once an ignition of the motor vehicle is deactivated and if it has been detected that a communication failure of the selector lever control instrument and/or of the parking brake control instrument is present.

18 . The method according to claim 11 , wherein the parking brake control instrument automatically activates the parking brake once an ignition of the motor vehicle is deactivated and if it has been detected that a communication failure of the transmission control instrument is present.

19 . A monitoring apparatus for operating a motor vehicle, configured to:
monitor whether a communication failure is present between a transmission control instrument of an automatic transmission of the motor vehicle, a selector lever control instrument of the automatic transmission, and/or a parking brake control instrument of an electronic parking brake of the motor vehicle; and/or monitor whether, on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of a selector lever itself for selection of drive stages of the automatic transmission, a parking position of the automatic transmission cannot be engaged; the transmission control instrument, the parking control instrument, and a display control instrument of a display device of the motor vehicle are to operated depending on the monitored control instruments between which a communication failure has been detected, and/or whether the parking position cannot be engaged on account of a malfunction of the automatic transmission itself and/or on account of a malfunction of the selector lever itself.
