1. A method, the method comprising:
- determining, using a sensor system, that wheels of a first axle of the vehicle are located on a roller dynamometer and that wheels of a second axle are not located on the roller dynamometer;
determining, using the sensor system, that a control element of a parking brake of the vehicle has been operated so that a first braking torque is demanded at the wheels of the first axle; and
responsive to the determination that the wheels of the first axle of the vehicle are located on the roller dynamometer and to the determination that the control element of the parking brake has been operated, actuating an actuator to automatically build up a second braking torque at at least one wheel brake of a wheel of the second axle.

Abstract
A method for securing a vehicle, whose wheels of one axle are on a dynamometer, against being unintentionally pushed out of the dynamometer during an inspection of the parking brake. In order to avoid endangerment of people who are in the surroundings of the vehicle, it is proposed to ascertain with the aid of a sensor system whether the vehicle is located on a dynamometer and, if this has been determined, to automatically generate a braking torque at a wheel brake of at least one wheel, which is located outside the dynamometer, after a control element of the parking brake has been operated.

6. A control unit of a vehicle, comprising:
-
a sensor system configured to determine that wheels of a first axle of the vehicle are located on a roller dynamometer and that wheels of a second axle are not located on the roller dynamometer, and to determine that a control element of a parking brake of the vehicle has been operated so that a first braking torque is demanded at the wheels of the first axle; and an actuator, responsive to the determination that the wheels of the first axle of the vehicle are located on the roller dynamometer and to the determination that the control element of the parking brake has been operated, configured to automatically build up a second braking torque at at least one wheel brake of a wheel of the second axle. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
