Problems solved by technology

However, these electromagnetic position sensors have the disadvantage that only a very low resolution can be obtained due to unstable magnetic field transitions
However, this leads to increased ambiguity of the positional information carried by the encoded rays, e.g. due to beam divergence

Embodiment Construction

[0030] from figure 1 A gearshift lever mechanism 1 according to an embodiment is seen, wherein the gearshift lever 2 is pivotally supported about a shift axis 3 on a bracket 4 which is fixedly mounted in a vehicle 5 including a vehicle transmission 6 . The shift lever 2 can be pivoted about the shift axis 3 into predetermined shift lever positions P, R, N and D. The bracket 4 is provided with a shift lever position detection device 7 , by means of which the current shift lever position of the shift lever 2 can be detected. The selector lever position detection device 7 has a sensor system 8 and is electrically connected to an evaluation device 9 , which in turn is electrically connected to a transmission controller 10 of the transmission 6 . Furthermore, a locking mechanism is provided which comprises a locking rail 11 arranged on the carrier 4 and a locking element 12 arranged on the selector lever 2 , which is tensioned relative to the locking rail 11 by means of a locking ...

Abstract

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.

Description

technical field [0001] The invention relates to a selector lever mechanism for operating a vehicle transmission with a carrier, a selector lever mounted movably on the carrier and adjustable into a predetermined selector lever position, and an optical selector lever position detection The device, the shift lever position detection device has a carrier, a plurality of optical sensors arranged on the carrier, an optical redirection element, at least one self-illuminating light source arranged on the carrier, by means of which the light can be redirected The element is sent to the sensor and has an encoding element arranged in the beam path of the light and equipped with an optical encoding, which can be moved into a predetermined encoding position by moving the selector lever. Background technique [0002] In order to detect the position of the selector lever, electromagnetic position sensors are often used. However, these electromagnetic position sensors have the disadvantag...
