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.

Method for controlling a hydrodynamic retarder that can be mechanically disengaged by a disconnect clutch

A hydrodynamic machine comprising a housing, arranged within said housing: at least one shaft; a toroidal working chamber that can be filled with a working medium, the toroidal working chamber including a first housing with a first bladed wheel and a second housing with a second bladed wheel; a step-up gear arranged with the first bladed wheel about a common rotational axis and mounted such that they can rotate independently of one another; and a coupling device operable to transfer torque between the step-up gear and the first bladed wheel.

Hydrodynamic machine

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.
