Abstract

A camera for a vehicle is described. The camera has at least one optoelectronic image converter, a camera housing in whose interior the image converter is accommodated, a camera optical element, which is accommodated in an optical mounting reference surface of the camera housing and is provided for imaging a primary detection area on the image converter, and a camera position reference surface for positioning the camera in relation to a vehicle window. At least one receiving surface for at least one light-guiding device e.g., one or a plurality of mirrors, is formed on the camera housing for deflecting light from at least one additional detection area to the camera optical element. The optical mounting reference surface, camera position reference surface, and receiving surface are preferably formed on a single housing component, e.g., an upper shell.

Claims

1. A camera for a vehicle, comprising:

an optoelectronic image converter;

a camera housing, in whose interior the image converter is accommodated;

a camera optical element accommodated in an optical mounting reference surface of the camera housing, the camera optical element provided for imaging a primary detection area on the image converter, and a camera position reference surface for positioning the camera in relation to a vehicle window; and

at least one receiving surface formed on the camera housing to which at least one light-guiding device is attached for deflecting light from at least one additional detection area to the camera optical element.

2. The camera as recited in claim 1, wherein the optical mounting reference surface, the camera position reference surface, and the at least one receiving surface are formed on a single housing component of the camera housing.

3. The camera as recited in claim 2, wherein the camera housing has an upper shell and a lower shell, and the optical mounting reference surface, the camera position reference surface, and the at least one receiving surface are formed on the upper shell.

4. The camera as recited in claim 2 wherein the housing component is one of an injection molded plastic part, a compression-molded plastic part, or a die cast metal part.

5. The camera as recited in claim 1, wherein the at least one light-guiding device is one of cemented onto or snapped into the at least one receiving surface.

6. The camera as recited in claim 1, wherein a first secondary detection area extends substantially upward for a blurred imaging of a surrounding area of a vehicle for ascertaining an ambient brightness when the camera is used in the vehicle.

7. The camera as recited in claim 1, wherein a second secondary detection area is directed to a surface area of the vehicle window for imaging the surface area on the image converter when the camera is used in the vehicle.

8. The camera as recited in claim 1, wherein the light-guiding devices include at least two cooperating mirrors to form a secondary optical element for deflecting at least one secondary detection area to the camera optical element.

9. The camera as recited in claim 8, wherein the secondary optical element includes at least one folding mirror designed as a planar mirror and one imaging mirror designed as a concave mirror.

10. The camera as recited in claim 8, wherein the camera has two secondary optical elements having two mirrors each and one secondary detection area each, a first mirror of each secondary optical element being situated in the primary detection area of the camera optical element, and a second mirror of each secondary optical element being situated on a rear upper area of the camera housing in each case.

11. The camera as recited in claim 10, wherein the two first mirrors are situated in a left lower area and right lower area of the primary detection area and the two second mirrors are situated interspaced to the left and right of the camera optical element and behind the camera optical element.

12. The camera as recited in one of the preceding claim 1, wherein on the camera housing, a plurality of camera position reference surfaces are interspaced from one another for snap-in accommodation in a camera mount.

13. A system, comprising:

a camera housing in whose interior the image converter is accommodated;

a camera optical element accommodated in an optical mounting reference surface of the camera housing, the camera optical element provided for imaging a primary detection area on the image converter, and a camera position reference surface for positioning the camera in relation to a vehicle window;

at least one receiving surface formed on the camera housing to which at least one light-guiding device is attached for deflecting light from at least one additional detection area to the camera optical element; and

a camera mount fastened to the vehicle window, the camera mount accommodating the camera on the camera position reference surfaces.
