Abstract:
The invention relates to a method for carrying out a cleaning operation for at least one braking device of a braking system in a motor vehicle, said method having the following steps:
setting a braking pressure by components of the braking device in accordance with a predefined braking pressure curve, wherein the braking pressure curve, during the cleaning operation, specifies braking pressures that vary over time for the braking device,
correcting a setpoint motor torque that is to be provided by a drive motor of the motor vehicle and that is dependent on a braking effect brought about by the set braking pressure,
the predefined braking pressure curve being selected such that a longitudinal deceleration of the motor vehicle, which is brought about by the predefined braking pressure curve, can be compensated for by a corresponding additional motor torque.
