Embodiment Construction

[0026] In the following description of the figures, the same elements or functions are denoted by the same reference numerals.

[0027] figure 1 An exemplary and schematic illustration shows a shift-by-wire system 1 with a transmission control unit or TCU 2 of a transmission control unit of a motor vehicle and with an actuating module or selector lever module 3 .

[0028] The gearshift modules 3 are designed to detect, by means of the actuating elements of each gearshift module 3 , in particular the gearshift lever, and the sensor device 4 the driver's desire regarding the operating state of the transmission, ie the driver's desire regarding the position of the gearshift lever. . In order to detect the selector lever position, the sensor system 4 has a plurality of sensors or receivers 4c arranged in each of the sensor arrays 4a,b, a redundant sensor array 4b being arranged next to the sensor array 4a for fail-safe detection. For clear reasons, in figure 1 The gear lever is...

Abstract

A shift by wire system for a motor vehicle, having a transmission control device and an actuation assembly, operationally connected thereto via an electrical connection. The actuation assembly is designed to generate a signal relating to an intention of the driver, corresponding to a position of the gearshift lever, by means of a gearshift lever and at least one sensor. The actuation assembly also has a controller unit, by means of which data based on the signal is communicated to the transmission control device via the electrical connection. The transmission control device monitors, in a remote manner, the controller unit in the actuation assembly via the electrical connection. The electrical connection is both a communication line for the data based on the signal and for the remote monitoring.

Description

technical field [0001] The invention relates to a shift-by-wire system for a motor vehicle. Background technique [0002] In the prior art, a shift-by-wire system for a motor vehicle is sufficiently known, for example, from patent document DE 10 2005 008 383 A1, which describes a shift-by-wire system for use with such a shift-by-wire device. manipulation device. [0003] Systems of this type have an actuating module for interaction with the driver, for example a gear lever module, which is equipped for this purpose with a selector lever or selector lever. By means of the selector lever of the actuating unit and the associated sensor system, the driver's wishes regarding the operating state to be achieved by the transmission can be detected and transmitted to the transmission control unit. Systems of this type use a powerless, in particular purely electrical, method of transmission for the transmission, ie "by-wire". [0004] It is common in modern systems to connect the a...
