1. A method for braking a vehicle including a hydraulic vehicle brake and an electromechanical braking device having an electric brake motor configured to adjust a brake piston against a brake disc, the method comprising:
- detecting that an automated driving procedure is being performed, the automated driving procedure being a procedure during which the vehicle one of (i) parks in a parking space and (ii) exits a parking space without the vehicle being actuated by a driver, the automated driving procedure including at least one braking procedure performed by the hydraulic vehicle brake;
in response to detecting that the automated driving procedure is being performed, generating an increased supply voltage that is greater than a vehicle electrical network voltage; and
in response to a failure of the hydraulic vehicle brake, driving the electric brake motor of the electromechanical braking device with the increased supply voltage to perform the at least one braking procedure of the automated driving procedure.
