The method further includes activating a parking mode of the parking brake automatically when the defined fault is detected. The automated parking brake is operable in different operating modes, a first operating mode corresponding to a drive mode and a second operating mode corresponding to the parking mode. ## Claims ### Claim 1 A method for operating a brake system with an automated parking brake for a motor vehicle, comprising: detecting a defined fault; and activating a parking mode of the automated parking brake automatically when the defined fault is detected, wherein the automated parking brake is operable in different operating modes, a first operating mode corresponding to a drive mode and a second operating mode corresponding to the parking mode. ### Claim 2 (depends on 1) The method according to claim 1, further comprising: detecting a parking situation; and activating the parking mode when the parking situation is detected. ### Claim 3 (depends on 2) The method according to claim 2, further comprising: detecting the parking situation when a defined speed criterion is satisfied. ### Claim 4 (depends on 2) The method according to claim 2, further comprising: detecting the parking situation based on a position of the motor vehicle. ### Claim 5 (depends on 1) The method according to claim 1, further comprising: detecting an automated parking process; activating the parking mode when the automated parking process is detected. ### Claim 6 (depends on 3) The method according to claim 3, further comprising: deactivating the parking mode when the defined speed criterion is no longer satisfied. ### Claim 7 (depends on 1) The method according to claim 1, further comprising: not activating the drive mode of the parking brake automatically when the defined fault is detected. ### Claim 8 (depends on 1) The method according to claim 1, further comprising: operating the parking brake in the different operating modes using an electronic circuit. ### Claim 9 (depends on 8) The method according to claim 8, further comprising: switching off the electronic circuit such that in the parking mode a switching signal input for actuating the parking brake is released and/or in the drive mode actuation of the parking brake is prevented. ### Claim 10 (depends on 1) The method according to claim 1, further comprising: executing the method only when there is an intact brake system. ### Claim 11 An electronic circuit device configured to operate an automated parking brake in different operating modes, a first operating mode corresponding to a drive mode and a second operating mode corresponding to a parking mode, the electronic circuit device comprising: a microcontroller configured to implement a method including: permitting actuation of the parking brake to be released in the parking mode; permitting the actuation of the parking brake to be prevented in the drive mode; and bringing about automated application of the parking brake when a defined fault is detected in the parking mode. ### Claim 12 (depends on 1) The method according to claim 1, wherein an apparatus is configured to execute the method. ### Claim 13 (depends on 3) The method according to claim 3, further comprising: detecting the parking situation when a speed of the motor vehicle is lower than a defined speed threshold. ### Claim 14 (depends on 4) The method according to claim 4, further comprising: detecting the parking situation based on a comparison of a GPS data of the motor vehicle and a map data. ### Claim 15 (depends on 14) The method according to claim 14, further comprising: detecting the parking situation based on a comparison of the GPS data of the motor vehicle and the map data for a car park and/or for a piece of private land and/or for a multistory car park and/or an underground car park. ### Claim 16 (depends on 6) The method according to claim 6, further comprising: deactivating the parking mode when a speed of the motor vehicle is higher than a defined speed threshold.
