Abstract

An instrument cluster arrangement adapted for mounting in a dashboard panel of a vehicle includes a display having a display surface providing a graphics area of the instrument cluster arrangement. The arrangement also includes a detector for monitoring a subject inside the vehicle, which is arranged to receive radiation providing information regarding the subject. The arrangement also includes a reflector arranged to redirect radiation from the subject toward the detector, where the detector and the reflector are both arranged in the instrument cluster arrangement, adjacent the display.

Claims

1. An instrument cluster arrangement adapted for mounting in a dashboard panel of a vehicle, the arrangement comprising:

a display having a display surface providing a graphics area of the instrument cluster arrangement;

a detector for monitoring a subject inside the vehicle, said detector being configured to receive radiation providing information regarding the subject; and

a reflector configured to redirect radiation from said subject towards said detector;

wherein the detector and the reflector are both configured to be arranged adjacent the display.

2. The instrument cluster arrangement in accordance with claim 1, the detector having an optical axis, and said detector configured to be arranged with said optical axis forming an angle with said display surface in the range −

10 to 30 degrees.

3. The instrument cluster arrangement in accordance with claim 2, wherein said detector is configured to be arranged with said optical axis being essentially parallel to said display surface.

4. The instrument cluster arrangement in accordance with claim 1, wherein said reflector is configured to be arranged between the detector and the display surface.

5. The instrument cluster arrangement in accordance with claim 1, wherein said display is configured to extend between an upper edge and a lower edge, and said reflector and said detector are configured to be arranged adjacent to the lower edge of the display.

6. The instrument cluster arrangement in accordance with claim 1, wherein said reflector is configured to be arranged so as to extend over a margin area of the display surface, said margin area constituting less than 10% of the total area of the display surface.

7. The instrument cluster arrangement in accordance with claim 1, wherein the reflector is configured to extend from a basal end configured to be arranged adjacent to said display area, and a free end opposite said basal end, said free end having an end surface forming an angle of approximately 90 degrees in relation to the display surface.

8. The instrument cluster arrangement in accordance with claim 1, wherein said reflector is transparent to visible light and reflective to said radiation, said reflector being a dichroic reflector.

9. The instrument cluster arrangement in accordance with claim 1, further comprising at least one radiation transmitter configured to be arranged adjacent said display, for transmitting radiation towards the subject.

10. The instrument cluster arrangement in accordance with claim 9, wherein said at least one radiation transmitter is configured to be arranged to transmit radiation in a direction towards the reflector, such that the reflector redirects the radiation towards the subject.

11. The instrument cluster arrangement in accordance with claim 1, wherein said instrument cluster is provided with an interface for transmitting signals and/or for providing voltage, wherein said interface is configured to be connected both to the display and to the detector.

12. The instrument cluster arrangement in accordance with claim 1, wherein said display forms a first unitary module, and said detector and reflector form a second unitary module, for mounting in a dashboard panel of a vehicle, said first and second unitary modules being connectable before mounting in said dashboard panel, so as to enable mounting of the instrument cluster arrangement in the dashboard as one assembled unit.

16. The instrument cluster arrangement in accordance with claim 1, the detector having an optical axis, and said detector configured to be arranged with said optical axis forming an angle with said display surface in the range −

10 to 15 degrees.

17. The instrument cluster arrangement in accordance with claim 1, the detector having an optical axis, and said detector configured to be arranged with said optical axis forming an angle with said display surface in the range −

10 to 10 degrees.

18. The instrument cluster arrangement in accordance with claim 1, wherein said reflector is configured to be arranged so as to extend over a margin area of the display surface, said margin area constituting less than 5% of the display surface.

19. The instrument cluster arrangement in accordance with claim 1, wherein said reflector is transparent to visible light and reflective to said radiation.

20. The instrument cluster arrangement in accordance with claim 1, further comprising two radiation transmitters configured to be arranged adjacent said display, for transmitting radiation towards the subject, the radiation transmitters configured to be arranged on opposite sides of the detector.

13. A vehicle comprising an instrument cluster arrangement mounted in a dashboard panel, the arrangement comprising:

a display having a display surface providing a graphics area of the instrument cluster arrangement;

a detector for monitoring a subject inside the vehicle, said detector arranged to receive radiation providing information regarding the subject; and

a reflector arranged to redirect radiation from said subject towards said detector;

wherein the detector and the reflector are both arranged adjacent the display.

14. A method for using an instrument cluster arrangement for a dashboard panel of a vehicle, the arrangement including a display having a display surface providing a graphics area of the instrument cluster arrangement, a detector for monitoring a subject inside the vehicle, said detector configured to be arranged to receive radiation providing information regarding the subject, and a reflector configured to be arranged to redirect radiation from said subject towards said detector, wherein the detector and the reflector are both configured to be arranged in said instrument cluster arrangement adjacent the display, the method comprising:

mounting said instrument cluster arrangement in the dashboard panel at a location such that radiation providing information regarding the subject in the vehicle may be directed from the subject to the reflector, and redirected by the reflector towards the detector.

15. The method of claim 14 further comprising configuring the instrument cluster arrangement for providing information regarding the subject to a subject-monitoring application, such as an eye-detection and/or head tracking application.
