System and method for detecting the surrounding environment of a motor vehicle using as adjustable infrared night vision system
View Patent ↗In a night vision system with which an image recording unit records the image of the surroundings of a motor vehicle, the recorded image is displayed by means of a display, wherein the position of the image recording device ( 2 ) is changed according to the driving situation.
1. A night vision system comprising:
an image recording unit recording the image of the surroundings of a motor vehicle;
a display showing the recorded image; and
a pivot for adjusting the vertical position of the image recording device, wherein the vertical position of the image recording device depends at least in part on a forward speed of the vehicle, such that the image recording device is pivoted upwardly when the forward speed of the vehicle increases and pivoted downwardly, so as to record an image outside a lower boundary of a forward field of vision of the motor vehicle driver through a from windshield of the motor vehicle, when the forward speed of the vehicle decreases, and
a processor programmed to:
receive information regarding a road on which the vehicle is travelling,
determine, based on the received information regarding the road, a typical speed of travel associated with the road, and
wherein the vertical position of the image recording device further depends at least in part on the determined typical speed of travel associated with the road on which the vehicle is travelling.
2. The night vision system according to claim 1 , wherein a horizontal position of the image recording device is changed.
3. The night vision system according to claim 1 , wherein a horizontal position of the image recording device is changed as a function of the road profile.
4. The night vision system according to claim 1 , wherein the image recording device is embodied as an infrared camera.
5. The night vision system according to claim 4 , wherein an infrared lighting device is present.
6. The night vision system according to claim 1 , wherein the image recording device is embodied as a radar.
7. The night vision system according to claim 1 , wherein the display is embodied as a head-up display.
8. A method of providing night vision in a vehicle, the method comprising the steps of:
recording an image of the surroundings of a motor vehicle by an image recording device,
displaying the recorded image by means of a display, and
controlling a vertical position of the image recording device based at least in part on a forward speed of the vehicle, such that the image recording device is pivoted upwardly when the forward speed of the vehicle increases and pivoted downwardly, so as to record an image outside a lower boundary of a forward field of vision of a motor vehicle driver through a front windshield of the motor vehicle, when the forward speed of the vehicle decreases,
receiving information regarding a road on which the vehicle is travelling,
determining, based on the received information regarding the road, a typical speed of travel associated with the road, and
wherein the vertical position of the image recording device further depends at least in part on the determined typical speed of travel associated with the road on which the vehicle is travelling.
9. The method according to claim 8 , wherein a horizontal position of the image recording device is changed.
10. The method according to claim 8 , wherein a horizontal position of the image recording device is changed as a function of the road profile.
11. The method according to claim 8 , wherein the image recording device is embodied as an infrared camera.
12. The method according to claim 11 , wherein an infrared lighting device is present.
13. The method according to claim 8 , wherein the image recording device is embodied as a radar.
14. The method according to claim 8 , wherein the display is embodied as a head-up display.
15. The night vision system according to claim 1 , wherein receiving information regarding the road on which the vehicle is travelling comprises recording images of the road by the image recording unit.
16. The night vision system according to claim 1 , wherein receiving information regarding the road on which the vehicle is travelling comprises receiving road-related information from a navigation system coupled to the night vision system.
