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

The invention relates to a reset device for a selector lever for a gear level of a transmission in a motor vehicle, said reset device comprising: an electrical drive device for operating an engaging element, in order to move the selector lever into a predetermined position; a position sensor for determining a position of the engaging element; and an electrical control device for controlling the drive device in accordance with the position of the engaging element. In addition, the position sensor comprises a first coil attached to the control device, and a magnetic flow element is mechanically coupled to the engaging element. The drive device is arranged in relation to the control device in such a way that the flow element influences the inductance of the first coil, in accordance with a position of the engaging 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 ...
