The invention relates to a method for permitting adaptation of the clutch torque of a proportional clutch in parallel hybrid vehicles, wherein given certain peripheral conditions the method is triggered automatically by a control device and the internal combustion engine rotates but is not ignited (phantom start).

Adaptation of the clutch torque of a clutch of a parallel-hybrid drive train of a vehicle

In a method for leak testing in an automated electrohydraulic clutch system in a motor vehicle, in which an electromechanical actuator controls the clutch travel of a clutch via a hydraulic piping system, in order that a defective system is detected reliably and rapidly, the leak in the clutch system is detected using a pressure measurement in the electromechanical actuator and compared to a characteristic clutch curve.

Method and device for leak testing in an automated electrohydraulic clutch system in a motor vehicle

A clutch for coupling an internal combustion engine in a torque-transmitting fashion and decoupling an internal combustion engine is disclosed. The internal combustion engine has a partial drive train that includes an electric machine. The clutch includes at least one adjustable element with which in conjunction with coupling means can be opened counter to a closing force generated by closing means. Locking means interacts with the adjustable element and has an adjustable locking element. The locking means interacting with the adjustable element in such a way that the coupling means are held open without an opening force having to be applied for this purpose by an adjustment means, or in such a way that the opening force which has to be applied by the adjustment means to hold the coupling means open is reduced.

Clutch and hybrid drive with clutch

A drive device for a vehicle includes an electric machine and an axle which is drivable by the electric machine. A disengageable mechanical coupling is provided between the drivable axle and the electric machine. This coupling is designed as a jaw coupling.

Device and method for operating a drive having an electrically drivable axle

A motor vehicle having an internal combustion engine, a differential pressure sensor or two pressure sensors for detecting a pressure difference, which may be in an exhaust tract of the internal combustion engine, and an evaluation unit for evaluating the detected pressure difference. Moreover, the present invention relates to a method for operating a motor vehicle. A controlling arrangement is provided for controlling an automatic start-stop system or an ignition system of the motor vehicle as a function of the result of the evaluation of the detected pressure difference used to detect immersion or submersion of a tailpipe of the exhaust tract in water, sludge, or a similar liquid medium in order to prevent the internal combustion engine from shutting off when the tailpipe is immersed or submerged.

Method for operating a fording-capable motor vehicle, and fording-capable motor vehicle

The invention relates to a device and to a method for controlling a coupling system having a coupling provided with a hydraulic actuation system, which includes an adjustable coupling part for connecting and separating a power transmission path between a coupling input side and a coupling output side, a hydraulic connection that connects the actuation unit to an electrohydraulic actuator that is arranged outside the coupling, and a control unit for controlling the actuator. The hydraulic connection forms a hydraulic system together with hydraulic components of the actuation unit and the actuator. According to the invention, a mechanical stop that delimits the adjustment of the coupling part on the actuation unit is formed. A pressure sensor monitors the pressure in the hydraulic system or a control signal of the actuator. The pressure sensor detects an installation of the coupling part on the stop based on occurring characteristic alterations of the pressure in the hydraulic connection or the control signal and controls the electrohydraulic actuator in accordance therewith and/or produces a diagnosis signal.
