Abstract

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.

Abstract

A hybrid vehicle is operated with a combustion engine, an electric machine and a gear unit. The vehicle has a first electrical system and a second electrical system as a vehicle electrical system. The first electrical system, which is operated at a higher voltage level than the second electrical system, operates the electric machine, an electrical energy storage device, an energy converter that transmits electrical power at least from the first electrical system into the second electrical system. An alternator is not used in the second electrical system. The first electrical system is a part of a transmission system that together with the components that are coupled to the transmission system is controlled by a transmission control unit. During power generation by the electric machine the energy supply of the second electrical system has a higher priority than a motor-mode support of the drive by the electric machine.

Abstract

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.
