Abstract: The present approach relates to a release device (105) for a vehicle (100) for detecting at least one position of a drive unit (106) in, or in the vicinity of, a slide unit (108). The release device (105) comprises at least the drive unit (106), the slide unit (108), and a sensor system (109). The drive unit (106) is or can be located at least partially in the slide unit (108) of the release device (105) in a first position, in order to lock or engage a parking lock (110) of the vehicle (100), and at least partially removed form the slide unit (108) in a second position, in order to release or disengage the parking lock (110). The slide unit (108) is configured to at least partially receive the drive unit (106) in at least the first position of the drive unit (106).

Abstract: The present approach relates to an unlocking device (105) for unlocking a park lock (110) of a vehicle (100). The unlocking device (105) comprises at least an eccentric apparatus (115), a slide unit (120) and an actuation apparatus (125). The eccentric apparatus (115) is designed to hold the slide unit (120) in a locking position in which the park lock (110) is locked or engaged in a first position in which the eccentric apparatus (115) is accommodated at least partly in the slide unit (120), and in a second position, to enable a transfer of the slide unit (120) into an unlocking position, in which the park lock (110) is unlocked or disengaged.

Abstract: The invention relates to a rotary switch (1) for a motor vehicle that has a rotational position detection device, wherein the rotational position detection device has at least a first light-based transmitter/receiver pair (5a), a second light-based transmitter/receiver pair (5b), and a light screening element (15), wherein the light-based transmitter/receiver pairs (5a, b) each have a light transmitter and a light receiver located opposite the light transmitter, such that a light transmission path (27) is formed between each transmitter and receiver, wherein the light screening element (15) determines the transmission properties of the respective light transmission paths (15) based on the rotational positions (D, N, R) of the rotary switch (1), wherein the transmitter/receiver pairs (5a, b) are configured such that a first spacing (d1) extending between a midpoint of the first light transmission path (27a) of the first pair (5a) and a rotational axis (9) of the rotary switch (1) differs from a second spacing

Abstract: An actuating device for selecting a gear of a shift-by-wire gearshift transmission may include a housing, a selection lever movable along at least one shift gate between at least a driving position and a parking lock position, a mechanical transfer element for transferring the movement of the selection lever to the gearshift transmission for actuating the parking lock, and a coupling system arranged between the selection lever and the transfer element, where the coupling system includes a slider element embodied to move in accordance with the movement of the selection lever. The actuating device may include an optical sensor arrangement arranged within the housing and including at least one transmitter/receiver pair having a transmitter and a receiver.
