Abstract: A steering wheel arrangement for a motor vehicle is provided. The steering wheel arrangement includes a steering wheel, a steering angle measuring arrangement for detecting the position of the steering wheel at a given moment, an electrical steering wheel heater, and a coil spring cassette that contains a ribbon cable through which flows an operating current of the steering wheel heater. The steering wheel arrangement further includes a current control device for the steering wheel heater. The current control device limits the operating current of the steering wheel heater depending on the detected position of the steering wheel.

Abstract: An operating arrangement for a vehicle includes a steering column retractable into and extendable out of a dashboard, a steering shaft that is retractable and extendable relative to the steering column, a steering wheel on an end of the steering shaft, and a steering column module arranged on the steering column between the steering wheel and the dashboard. The steering column module has a screen positioned behind the steering wheel. In a manual vehicle driving mode, the steering column is extended out of the dashboard to position the steering wheel and the steering column module away from the dashboard. In an automatic (or autonomous) vehicle mode, the steering column is retracted into the dashboard to position the steering column module against the dashboard and the steering shaft is retracted relative to the steering column to position the steering wheel adjacent the dashboard with the screen resting against the steering wheel.

Abstract: A system for detecting the absolute rotational angle of a shaft rotatable more than one revolution includes a drive wheel connected to the shaft to rotate therewith. The drive wheel includes measurement sectors adjacent to one another in a circumferential direction. First and second driven wheels are engaged to the drive wheel. First and second sensors monitor rotational positions of the driven wheels to thereby detect an absolute rotational angle of the shaft. A third sensor monitors a relative angular position of the shaft in relation to a detected one of the measurement sectors to thereby detect the relative angular position of the shaft within one revolution of the shaft. The detected absolute rotational angle of the shaft is refined with the detected relative angular position of the shaft to thereby generate the absolute rotational angle of the shaft with more precision.

Abstract: A steering column module includes a tubular jacket rotatably supporting a steering shaft, a switch module having a carrier including contact pressure surfaces, and a device for fastening the switch module to the tubular jacket. The device includes a clamp assembly between the tubular jacket and the switch module for exerting a clamping force on the tubular jacket. The clamp includes two half clamps each having two outwardly bent end flanges. The end flanges are axially movably accommodated in the carrier such that when the switch module is axially moved onto the tubular jacket the end flanges come into contact with axial end stops of the tubular jacket and the contact pressure surfaces of the carrier. The contact pressure surfaces exert forces on the end flanges as the switch module is axially moved onto the tubular jacket thus fastening the switch module to the tubular jacket with a clamping action.

Abstract: A steering wheel (13) for a motor vehicle includes a steering wheel module (1) supporting electrical/electronic subassemblies (18). The steering wheel module is inserted from a front side of the steering wheel into a center of the steering wheel in order to be attached to the steering wheel. A lower end of the steering wheel module forms a torsion module (8) of a torque detection device for a steering power-assist system. The torsion module is operable to receive and be attached to a steering spindle (14) of a steering column on the back side of the steering wheel in order to attach the steering wheel to the steering spindle when the steering wheel module is attached to the steering wheel.

Abstract: An electric shifting device for a vehicle includes a shift lever, a gate channel, and a detent device. The detent device has a spring-loaded pin and a detent contour cooperating therewith. The detent contour includes first and second paths and a connection path therebetween. The detent contour is movable relative to the channel between a first position in which the first path is aligned with the channel and a second position in which the second path is aligned with the channel. The lever is connected to the pin such that the lever is movable within the channel along the first path when the detent contour is in the first position and within the channel along the second path when the detent contour is in the second position and such that the lever is movable along the connection path between the paths when the detent contour moves between the positions.
