Abstract
The present disclosure relates to a device for the optoelectronic detection of different positions of a selection lever for selecting different gear steps of a gearshift transmission, in particular a motor vehicle transmission. The detection device can be coupled to the selection lever, and comprises at least one light source for emitting light, and one light sensor for detecting the emitted light. The detection device is distinguished in that the light sensor is provided for detecting a light intensity, or a wavelength of the emitted light, respectively, filtered by means of a light filter that can be disposed in a light path between the at least one light source and the light sensor, and to transmit data regarding the detected light intensity, or wavelength, respectively, to an evaluation device. Predetermined light intensities, or predetermined filtered wavelengths, respectively, are assigned thereby to predetermined selection lever positions, which are selected form different positions of the selection lever.
