Abstract
A method for controlling a hydrodynamic retarder in a motor vehicle that can be mechanically disengaged via a disconnect clutch, whereby at least one of the rotational speed of a revolving bladed rotor and the speed of a motor vehicle is monitored and a disconnect clutch is engaged below at least one of a pre-specified rotational speed of the revolving bladed rotor and a pre-specified speed of the motor vehicle, regardless of a request made by a driver assist system or by operation of an input device by the operator of the motor vehicle to turn on the hydrodynamic retarder.
