GEAR CHANGE LEVER DEVICE FOR A VEHICLE GEARING, EVALUATION DEVICE FOR A GEAR CHANGE LEVER DEVICE AND METHOD FOR ELECTRONIC ACTIVATION OF A VEHICLE DEVICE

摘要

A gear change lever device for a vehicle transmission with a holder, a gear change lever movably arranged on a holder and comprising a gripping surface, wherein the gear change lever can be moved to pre-determined positions (P, R, N, D), a sensor device, by which the current position of the gear change lever can be detected, an evaluation device coupled to the sensor device for the control of transmission, by means of which in cooperation with the sensor device a change in the gear change lever position can be recognized, and at least one touch sensor coupled to the evaluation device and arranged on the gear change lever in the area of the grip surface, by means of which a human touch of the grip surface can be detected and information about the touch state of the gripping surface can be sent to evaluation device.

主权项

1. A gear lever device for a vehicle transmission, the gear lever device comprising:
a holder, a gear lever movably mounted on the holder, the gear lever comprising a gripping surface, wherein the gear lever is moveable to predetermined gearshift positions; a sensor device for determining a current gear lever position; an evaluation device for controlling the transmission, the evaluation device coupled to the sensor device, wherein the sensor device and evaluation device are configured to detect changes in the gear lever position; and a touch sensor electronically coupled to the evaluation device and arranged on the gear lever in the region of the gripping surface, wherein the touch sensor is configured to detect a human touch on the gripping surface and send information about a touch state of the gripping surface to the evaluation device, wherein the evaluation device is configured to set and store a reference value for a sensitivity of the touch sensor on the basis of the information regarding the touch state when the gripping surface is touched, wherein the evaluation device is configured to subsequently set a sensitivity value on the basis of the information regarding the touch state with a further touching of the gripping surface, and wherein the evaluation device is configured to evaluate a comparison of the reference value and the sensitivity value in order to determine a necessity for sending an electronic control signal.
