Method for controlling the luminance of a lighting device for a display element and display device for vehicles containing the display element

摘要

The method involves detecting a movement condition of a vehicle by detection of acceleration values of the vehicle by using X, Y-acceleration sensors, and calculating speed of the vehicle from the detected acceleration values. Brightness of an illumination device for a display element is controlled by a control device (12) based on the movement condition and/or a position of the vehicle, where the brightness is reduced when the vehicle is moved. A display device is connected with a control device of the vehicle by an interface. An independent claim is also included for a display device for a vehicle comprising a sensor device.
