Abstract

A vision system for providing exterior rear view for a vehicle driver, includes: an image capturing device supported by a hingeable support frame for hinging the image capturing device around a central axis of the vision system for adjusting the view of the vision system.

Claims

1. Vision system (1) for providing exterior rear view for a vehicle driver, the system comprising;

an image capturing device (2) supported by a hingeable support frame (13) for hinging the image capturing device around a central axis (3) of the vision system for adjusting the view of the vision system,

a housing (6) for accommodating the image capturing device therein, the housing (6) comprising a first stationary housing part (5) and a second housing part (4) coupled with the first stationary housing part (5) for accommodating the image capturing device in the housing (6), and wherein the second housing part (4) comprises an entrance window (7) for allowing an image to be captured by the image capturing device, and wherein the second housing part (4) is moveable coupled with the first stationary housing part (5) for cleaning the entrance window (7) of the second housing part (4),

a cleaning device (8) coupled with the first stationary housing part and arranged for cleaning the entrance window,

a mechanical adjusting device (9) comprising a drive system (10) for adjusting the view of the vision system,

wherein the drive system is coupled with both the hingeable support frame for adjusting the angular position of the image capturing device, and with the second housing part for moving the entrance window with respect to the cleaning device.

2. Vision system according to claim 1, wherein the drive system is directly coupled with the second housing part.

3. Vision system according to claim 1, wherein the drive system is coupled with the hingeable support frame through a coupling device for uncoupling the drive system and the hingeable support frame when a desired field of view of the vision system is achieved.

4. Vision system according to claim 3, wherein the coupling device comprises a friction coupling system for uncoupling the drive system and the hingeable support frame when a support frame driving force exceeds a driving force threshold.

5. Vision system according to claim 3, comprising a cam system coupled with the hingeable support frame and the first stationary housing part the for imposing at least one angular position to the hingeable support frame for providing a desired field of view for the vision system.

6. Vision system according to claim 1, comprising a source of radiation for radiating the field of view, and wherein the entrance window comprises at least a first and a second entrance window section wherein the first entrance window section is suitable for use during daylight conditions and the second entrance window section is suitable for use in dim or darkness in conjunction with the source of radiation.

7. Vision system according to claim 6, comprising a control unit for controlling the position of the entrance window, wherein the image capturing device is operationally coupled with the control unit for providing a control signal from the image capturing signal to the control unit.

8. Vision system according to claim 7, wherein the source of radiation is operationally coupled with the control unit, and the source of radiation is arranged for allowing at least a part of emitted radiation to affect directly on the image capturing device through the entrance window.

9. Vision system according to claim 6, comprising a further image capturing device which is stationary arranged for providing a determined field of view.

10. Vision system according to claim 9, wherein the image capturing device and the further image capturing device are arranged such that the devices are aligned with the central axis.

11. Vision system according to claim 1, wherein the second housing part is gastight coupled with the first stationary housing part for filling the housing with gas, preferably for filling the housing with gas at an overpressure.

12. Vision system according to claim 1, wherein the second housing part (7) extends around the image capturing device (2, 12).

13. Vision system according to claim 1, wherein the second housing part (7) is provided with a curvature.

14. Vision system according to claim 1, wherein the second housing part extends circumferential around the image capturing device, and preferably the entrance window extends circumferential around the image capturing device.

15. Vision system according to claim 2, wherein the drive system is coupled with the hingeable support frame through a coupling device for uncoupling the drive system and the hingeable support frame when a desired field of view of the vision system is achieved.

16. Vision system according to claim 15, wherein the coupling device comprises a friction coupling system for uncoupling the drive system and the hingeable support frame when a support frame driving force exceeds a driving force threshold.

17. Vision system according to claim 15, comprising a cam system coupled with the hingeable support frame and the first stationary housing part the for imposing at least one angular position to the hingeable support frame for providing a desired field of view for the vision system.
