A device for locking an operation element of an automatic transmission of a vehicle may comprise a rotationally mounted locking comb including a locking contour configured to be coupled with an operation element. The device may further comprise a locking element, where the locking element is configured to be arranged in a first position outside the locking contour to release the locking comb for a rotational movement to allow a shifting movement of the operation element. The locking element may be configured to be arranged in a second position in the locking contour to fix the locking comb for locking the operation element. The device may further comprise a rotationally mounted set ring with a control contour for guiding the locking element between the first position and the second position.

A device for shifting an operation element of an automatic transmission of a vehicle in a parking position includes a rotationally mounted locking comb directly coupled with the operation element, with a stop member, a locking pin which is designed in a first position to fix the locking comb and in a second position to release the locking comb for a rotational movement, and a rotationally mounted set collar with a switching cam and a catch, wherein the switching cam is formed at a rotational movement of the set collar to move the locking pin from the first position to the second position, and the catch is formed at the rotational movement of the set collar to entrain the stop member to turn the locking comb so far that the operation element is shifted to the parking position.

A selector lever arrangement for operating a transmission in a motor vehicle with a mounting fixture, a selector lever which is mounted at the fixture in such a way that it can be moved into the designated selector lever positions and an optical detection device for the selector lever position, which includes a carrier, several optical sensors which are arranged on the carrier, an optical deflector, at least one self-luminous light source that is arranged on the carrier, by means of which light can be directed onto the sensors via the deflectors, and a coding element equipped with an optical coding that is arranged within the optical path, which can be shifted into the designated coding positions by means of moving the selector lever, whereby the coding element is intended to be allocated between the sensors and the deflector that is made in form of a light guiding element, which is arranged at the carrier.

A position detection device having a first electrode pair, an electrically conductive body that forms an electrical resistor which is electrically connected to the electrodes of the first electrode pair and extends in a first direction (y), between them, and with a measurement electrode which is in electrically conductive contact with the surface of a measurement area of the body located between the electrodes of the first electrode pair and can move relative thereto. The body is electrically connected to the electrodes of a second electrode pair and extends between them in a second direction (x) such that the measurement area is located between the electrodes of the second electrode pair.

Position detection device

A method of diagnosing an electronic display device () having a screen () and a graphics memory () in which image data (), of an image displayed or to be displayed on the screen (), are one of stored or changed. A measured value () characterizes a current consumption or the change in current consumption of the screen () or display device () while a reference value () characterizes the current consumption or the change in current consumption of the screen () or display device () on the basis of the image data () or the change in image data (). The method compares the reference value () to the measured value () to determine any malfunction or error in the electronic display device ().
