Abstract

An in-vehicle display device includes (a) a display unit provided on a surface of an instrument panel of a vehicle, opposed to a windshield of the vehicle, and configured to indicate a plurality of information dots V in a row or in a rectangular array on the windshield such that the necessary information dots are selectably displayed from among the plurality of the information dots and superposed upon a real image viewed through the windshield, (b) a target information acquisition unit that obtains target information of which a driver of the vehicle is to be notified, and (c) a display control unit that controls the display unit and makes the display unit indicate the predetermined information dots V that correspond to the target information that has been obtained by the target information acquisition unit.

Claims

1. An in-vehicle display device comprising:

a display unit that is provided on a surface of an instrument panel of a vehicle, opposed to a windshield of the vehicle, and configured to selectably indicate a plurality of information dots in a row or in a rectangular array on the windshield such that the plurality of information dots are superposed on a real image in a traveling direction of the vehicle;

a target information acquisition unit configured to obtain target information that a driver of the vehicle is to be informed of; and

a display control unit that controls the display unit and makes the display unit indicate the information dot that corresponds to the target information obtained by the target information acquisition unit.

2. The in-vehicle display device as set forth in claim 1, wherein the display unit includes a plurality of point light sources arranged in a row or in a rectangular array over a range wider than a range of vision of the driver during driving, each point light source being configured to indicate one of the information dots, and the display control unit makes the point light sources indicate the information dot that corresponds to the target information unit.

3. The in-vehicle display device as set forth in claim 1 further comprising an obstacle detecting unit that detects an obstacle in the traveling direction of the vehicle, wherein the target information acquisition unit obtains the target information indicative of a position of the obstacle detected by the obstacle detecting unit, and the display control unit makes the display unit selectably indicate the information dot from among the plurality of information dots in accordance with the target information obtained by the target information acquisition unit such that the selected information dot is indicated near the obstacle or superposed on the obstacle on the windshield of the vehicle.

4. The in-vehicle display device as set forth in claim 2 further comprising an obstacle detecting unit that detects an obstacle in the traveling direction of the vehicle, wherein the target information acquisition unit obtains the target information indicative of a position of the obstacle detected by the obstacle detecting unit, and the display control unit makes the display unit selectably indicate the information dot from among the plurality of information dots in accordance with the target information obtained by the target information acquisition unit such that the selected information dot is indicated near the obstacle or superposed on the obstacle on the windshield of the vehicle.

5. The in-vehicle display device as set forth in claim 1 further comprising an area-setting-information storage unit that stores area setting information used to enable or disable presentation of the information dot in a predetermined area of the windshield, wherein the display control unit specifies a display area in which the information dot is to be indicated and makes the display unit indicate the information dot in the specified display area in accordance with the area setting information stored in the area-setting-information storage unit.

6. The in-vehicle display device as set forth in claim 2 further comprising an area-setting-information storage unit that stores area setting information used to enable or disable presentation of the information dot in a predetermined area of the windshield, wherein the display control unit specifies a display area in which the information dot is to be indicated and makes the display unit indicate the information dot in the specified display area in accordance with the area setting information stored in the area-setting-information storage unit.

7. The in-vehicle display device as set forth in claim 3 further comprising an area-setting-information storage unit that stores area setting information used to enable or disable presentation of the information dot in a predetermined area of the windshield, wherein the display control unit specifies a display area in which the information dot is to be indicated and makes the display unit indicate the information dot in the specified display area in accordance with the area setting information stored in the area-setting-information storage unit.

8. The in-vehicle display device as set forth in claim 4 further comprising an area-setting-information storage unit that stores area setting information used to enable or disable presentation of the information dot in a predetermined area of the windshield, wherein the display control unit specifies a display area in which the information dot is to be indicated and makes the display unit indicate the information dot in the specified display area in accordance with the area setting information stored in the area-setting-information storage unit.
