A method for controlling a hydrodynamic retarder in a motor vehicle that can be mechanically disengaged via a disconnect clutch, comprising a drive motor whose power output is controlled via an actuator such as a foot pedal or a lever; whereby in an overrun operation the acceleration of the motor vehicle is collected or detected and compared with a pre-specified acceleration value; and whereby in the non-braking mode the disconnect clutch is engaged, regardless of an initiation of a braking mode by an operator of the motor vehicle or a driver assist system and the working chamber is maintained drained when the acceleration exceeds an acceleration limit.
