Embodiment Construction

[0024] figure 1 A control system 100 for controlling a transmission in a motor vehicle is shown. A gear stage of the transmission can be selected directly or indirectly by means of the monostable gear selector lever 105 . To this end, the selector lever 105 can be brought into various positions 110 . In the exemplary illustrated embodiment, the positions A1 , A2 , B1 and B2 are shown in the vertical direction in the shift gate on the right, which corresponds to the automatic gate of the automatic transmission. Likewise, position N, which corresponds to the neutral position of the selector lever, is also in the right-hand region. Due to its monostable mounting, the selector lever automatically returns to position N in order to assume its initial position corresponding to the position of the selector lever not actuated. parts. Through the shifting movement in the automatic slide, at least the gear stage D for forward driving, the gear stage N for the idling part of the transm...

Abstract

Setback for transmission selector lever. A resetting device for a selector lever of a transmission gear stage in a motor vehicle comprises an electric drive for displacing an engaging element to move the selector lever into a predetermined position, a device for determining the position of the engaging element A position sensor and an electrical actuation device for actuating the drive as a function of the position of the engagement element. In this case, the position sensor comprises a first coil mounted on the actuation device, and the magnetic flux element is mechanically coupled to the engaging element. The drive device is arranged relative to the control device in such a way that the flux element influences the inductance of the first coil as a function of the position of the engagement element.

Description

technical field [0001] The invention relates to a return device for a transmission selector lever in a motor vehicle. The invention relates in particular to the detection of the position of an element of a callback device. Background technique [0002] A motor vehicle includes a transmission with a plurality of gear stages. The operation of the transmission can be influenced by the driver of the motor vehicle by means of a selector lever. For example, a manual program can be selected, in which the driver has to explicitly trigger the gear change of the transmission via the gear selector. Alternatively, an automatic program can be selected, in which the control unit carries out the selection and engagement of the gear stages in the transmission. These programs can also be selected with the gear selector. In order to be able to start the engine at the beginning of driving, an automatic program must be preset. For this purpose, for example, the selector lever can be moved ...
