A reset device for a gearshift lever for a gear step of a transmission in a motor vehicle comprises an electric drive device for controlling an operating element, in order to move the gearshift lever into a predetermined position, a position sensor for determining a position of the operating element, and an electric activation device for activating the drive device, depending on the position of the operating element. The position sensor comprises a first coil thereby, which is attached to the activation device, and a magnetic flux element is mechanically coupled to the operating element. The drive device is disposed in relation to the activation device, such that the flux element influences the inductivity of the first coil, depending on a position of the operating element.
A reset device (115) for a gearshift lever (105) for a gear step of a transmission in a motor vehicle, wherein the reset device (115) comprises:
The reset device (115) according to one of the preceding claims, wherein the flux element (140) comprises a section having a magnetically soft material, in order to amplify a magnetic flux of the magnetic field provided by the first coil (135), when the section is brought into proximity with the first coil (135).
The reset device (115) according to one of the preceding claims, wherein the flux element (140) comprises a section having an electrically conductive material, in order to reduce a magnetic flux of the magnetic field provided by the first coil (135), when the section is brought into proximity with the first coil (135).
