1. A method for carrying out a cleaning operation for at least one braking device of a braking system in a motor vehicle, comprising 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;
wherein the setpoint motor torque to be set is corrected by the drive motor of the motor vehicle with the aid of a longitudinal acceleration control, which sets the setpoint motor torque as a function of a deviation between a predefined setpoint longitudinal acceleration specification and an actual longitudinal acceleration specification, wherein the setpoint longitudinal acceleration specification specifies a longitudinal acceleration of the motor vehicle upon activation of the cleaning operation or is determined from an accelerator pedal position during the cleaning operation.
