摘要： A method for controlling a separating clutch in a power train of a vehicle having a drive motor and a retarder. The clutch is arranged such that a rotor of the retarder is switched into a drive connection with the motor and/or power train via the clutch and a working chamber of the retarder can be filled with an operating medium to build up a braking power such that braking torque is exerted by the retarder onto the power train and/or motor. A control system switches the clutch into a closed or an open position. The switching of the clutch into the closed position occurs depending on an input signal to the controller, and the clutch is switched back into the open position depending on essentially no medium being present in the working chamber of the retarder and that predetermined limits of an operating and/or environmental parameter are not exceeded.

摘要： 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.

摘要： A drive train has a hydrodynamic retarder including a rotating bladed rotor and bladed stator, forming a working chamber for hydrodynamic transmission of power from rotor to stator, a power input feeding drive power to the retarder, and a synchronized separating clutch connected between power input and rotor. The clutch has two clutch halves, friction elements contacting each other and mechanical blocking elements. The friction elements equalize rotational speed between clutch halves, and the blocking elements form-lockingly connect the clutch halves. The clutch has an actuator displaceable along a displacement travel, over a first distance bringing the friction elements into mutual contact, and a second distance adjoining the first distance to synchronize the friction elements and rotational speed for locking with the blocking elements. At least one displacement sensor directly or indirectly detects displacement travel by the actuator and/or position of the actuator on the displacement travel.

摘要： A cooling circuit for a motor vehicle having a cooling medium pump that circulates a cooling medium in the cooling circuit having a hydrodynamic retarder. The cooling circuit further includes a main circuit in which the cooling medium pump and a drive motor of the motor vehicle, as well as a heat exchanger are positioned. A secondary branch of the cooling circuit includes a feed that branches off from the main circuit at a branch-off point and ends in the hydrodynamic retarder, and a return which proceeds from the hydrodynamic retarder and ends at a junction location in the main circuit. The return ends upstream of the branch-off location of the feed as viewed in a flow direction of the cooling medium in the main circuit, however on the same side of the cooling medium pump or at the branch-off location of the feed in the main circuit.

摘要： The invention concerns a method for controlling a vehicle drive train with a hydrodynamic retarder which can be engaged and disengaged mechanically via a coupling, whereas the retarder comprises a working chamber formed between two bladed wheels, which is filled with a working fluid for generating a braking torque after detecting a retarder switch-on signal and is emptied of the working medium after detecting a retarder switch-off signal to turn off the braking torque, and the retarder is driven in braking mode by means of a drive shaft via the closed coupling to constitute a hydrodynamic circuit of the working fluid in the working chamber.The invention is characterised in that the speed of the vehicle and/or the rotational speed of the drive shaft is detected or calculated and the coupling is closed above a preset limit speed and/or above a preset limit rotation speed independent of the detection of a retarder switch-on signal to drive the retarder.
