Abstract

A display system for use in a vehicle is disclosed including an imager configured to capture images corresponding to a field of view rearward of the vehicle. The imager is in communication with a processing unit configured to receive data representative of the captured images from the imager. A display is in communication with the processing unit which is configured to display images based on the data representative of the captured images received by the processing unit. The processing unit is configured to receive vehicle operating data from the vehicle and data corresponding to a detection of an object in proximity of the vehicle. In response to the vehicle operating data and the object detected, the processing unit is configured to control the field of view of the at least one imager.

Claims

1. A display system for use in a vehicle, comprising:

an imager configured to capture images corresponding to a captured field of view rearward of the vehicle;

a processing unit in communication with the imager, the processing unit configured to receive data representative of the captured images;

a display in communication with the processing unit, the display configured to display images based on the data representative of the captured images received by the processing unit; and

wherein the processing unit is configured to;

detect a curve direction of a road depicted in the data representative of the captured images with a curve detection algorithm; and

adjust a position of a selected portion of the captured field of view based on the curve direction.

2. The display system according to claim 1, wherein the processing unit is configured to:

receive vehicle directional data from a sensor of the vehicle;

process the directional data to identify an operating direction of the vehicle; and

control the field of view of the images displayed on the display in response to the directional data.

3. The display system according to claim 2, further comprising:

a direction detector configured to identify the operating direction, wherein the direction detector comprises a steering angle detector configured to measure the operating direction of the vehicle.

4. The display system according to claim 2, wherein the direction detector comprises a yaw rate sensor configured to measure the operating direction of the vehicle.

5. The display system according to claim 2, wherein the processing unit is further configured to:

pan the imager adjusting a display angle of the captured field of view in response to the operating direction of the vehicle.

6. The display system according to claim 1, wherein the captured field of view comprises a displayed field of view focusing on the selected portion of the captured field of view.

7. The display system according to claim 6, wherein the processing unit is further configured to:

pan a position of the displayed field of view in the captured field of view based on an operating direction of the vehicle.

8. The display system according to claim 6, wherein the processing unit is further configured to:

control the display to display the displayed field of view such that the extents of the displayed field of view extend to a perimeter of the display.

9. The display system according to claim 6, wherein the processing unit is further configured to:

control the display to display the displayed field of view as a zoomed portion of the captured field of view.

10. A system for presenting a rearward view from a vehicle, comprising:

an imager configured to capture images comprising an optic field of view rearward of the vehicle;

a processing unit in communication with the imager, the processing unit configured to receive data representative of the captured images;

a display in communication with the processing unit, the display configured to display images based on the data representative of the captured images received by the processing unit in a displayed field of view; and

wherein the processing unit is configured to;

receive vehicle directional data from a sensor of the vehicle;

process the directional data to identify a steering direction of the vehicle;

dynamically alter the displayed field of view of the data representative of the captured images based on the steering direction of the vehicles;

detect an object within a distance range of the vehicle based on the data representative of the captured images; and

expand the displayed field in response to the detection of the object within the distance range.

11. The system according to claim 10, wherein the sensor comprises a steering sensor configured to detect a steering angle of the vehicle.

12. The system according to claim 11, wherein the processing unit is further configured to:

pan the imager adjusting a display angle of the captured field of view in response to the steering angle of the vehicle.

13. The display system according to claim 11, wherein the processing unit is further configured to:

adjust a position of the displayed field of view within the captured field of view in response to the steering angle of the vehicle.

14. The display system according to claim 11, wherein the processing unit is further configured to:

pan a position of the displayed field of view in the captured field of view commensurate to a magnitude and direction of the steering angle of the vehicle.

15. The system according to claim 10, wherein the processor is further operable to change an extent of the displayed field of view from a first field of view to a second field of view in response to the vehicle exceeding a speed threshold communicated in vehicle operating data.

16. The system according to claim 15, wherein the second field of view comprises zoomed extents focusing on a smaller portion of the optic field of view.

17. A method of controlling a display system of a vehicle, the method comprising a display processing unit, the steps of:

receiving and analyzing image data from an imager of a scene rearward of a vehicle;

detecting an operating direction of the vehicle, wherein the operating direction is detected based on a steering angle of the vehicle;

displaying the image data on a display;

dynamically altering the displayed image data by changing a portion of the field of view of the image data displayed based on the steering angle of the vehicle; and

detecting a curve direction of a road depicted in the image data with a curve detection algorithm and adjusting a position of the portion of the field of view in the curve direction.
