Abstract

A monitoring device for monitoring a display device, displaying target values. The values being predetermined by a target value specification device. The monitoring device has an image acquisition device, an analysis device, and a comparison device. The image acquisition device generates a recording of said display. The analysis device generates an analysis of said the recording. The comparison device compares the analysis and the target value. A signal can be generated if the analysis and the target value are different.

Claims

1. A monitoring device configured to monitor a display that displays desired values that are prescribed by a desired value stipulation device, comprising:

an image acquisition device configured to generate a recording of an information content of the display;

an evaluation device configured to generate an evaluation value of the recording;

a comparison device configured to compare the evaluation value and the desired value;

a generator configured to generate a signal at least when the evaluation value and the desired value are different;

a mirror arranged in the beam path between the display and the image acquisition device; and

a printed circuit board on which the display and the image acquisition device are arranged.

2. The monitoring device as claimed in claim 1, further comprising a further mirror arranged in the beam path between the display and the image acquisition device.

3. The monitoring device as claimed in claim 1, wherein the display is arranged in a combination instrument of a motor vehicle.

4. The monitoring device as claimed in claim 3, wherein the desired value stipulation device prescribes a gear position of a motor vehicle to be displayed.

5. The monitoring device as claimed in claim 1, wherein the monitoring device is designed to monitor a plurality of desired values to be displayed.

6. The monitoring device as claimed in claim 1, wherein at least one of the display and a device that supplies the desired values is blocked based at least in part on the signal.

7. The monitoring device as claimed in claim 1, wherein the desired value stipulation device prescribes a gear position of a motor vehicle to be displayed.

8. A monitoring device configured to monitor a display that displays desired values that are prescribed by a desired value stipulation device, comprising:

an image acquisition device configured to generate a recording of an information content of the display;

an evaluation device configured to generate an evaluation value of the recording;

a comparison device configured to compare the evaluation value and the desired value;

a generator configured to generate a signal at least when the evaluation value and the desired value are different;

a mirror arranged in a beam path between the display and the image acquisition device, wherein the mirror is semi-transparent; and

a printed circuit board on which the display and the image acquisition device are arranged.

9. The monitoring device as claimed in claim 8, further comprising a further mirror arranged in the beam path between the display and the image acquisition device.
