Abstract

A communication system for vehicles includes a camera disposed at a first vehicle and having a field of view exterior of the first vehicle. The camera captures image data. A first communication device disposed at the first vehicle wirelessly transmits image data captured by the camera. A second communication device disposed at a second vehicle receives the transmitted captured image data from the first communication device. At least one of (i) an image processor disposed at the second vehicle processes the received transmitted captured image data for a driver assistance system of the second vehicle and (ii) a display of the second vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the second vehicle.

Claims

1. A communication system for vehicles, said communication system comprising:

a camera disposed at a first vehicle and having a field of view exterior of the first vehicle, said camera capturing image data;

a first communication device disposed at the first vehicle, said first communication device wirelessly transmitting image data captured by said camera;

a second communication device disposed at a second vehicle, said second communication device receiving the transmitted captured image data from said first communication device; and

wherein at least one of (i) an image processor disposed at the second vehicle processes the received transmitted captured image data for a driver assistance system of the second vehicle and (ii) a display disposed at the second vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the second vehicle.

2. The communication system of claim 1, wherein said first and second communication devices comprise first and second dedicated short range communication devices.

3. The communication system of claim 2, wherein each of said first and second dedicated short range communication devices have a first channel dedicated for safety related communications and a second channel dedicated for communication of the captured image data.

4. The communication system of claim 1, wherein the first vehicle comprises a trailer and the second vehicle comprises a towing vehicle that is towing the trailer.

5. The communication system of claim 4, wherein the trailer includes a plurality of cameras, and wherein at least one of said cameras has a field of view interior of the trailer.

6. The communication system of claim 4, wherein an image processor of the towing vehicle processes the received transmitted captured image data to detect objects exterior of the trailer.

7. The communication system of claim 4, wherein a display of the towing vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the towing vehicle while the driver is driving the towing vehicle and towing the trailer.

8. The communication system of claim 1, wherein the first vehicle comprises a lead vehicle of a platoon of vehicles and wherein the second vehicle comprises at least one following vehicle of the platoon of vehicles that is following the lead vehicle.

9. The communication system of claim 8, wherein said camera comprises a forward viewing camera of the lead vehicle.

10. The communication system of claim 9, wherein an image processor of the following vehicle processes the received transmitted captured image data for a driver assistance system of the following vehicle.

11. The communication system of claim 10, wherein said image processor processes the received transmitted captured image data for lane marker detection at the road ahead of the lead vehicle.

12. The communication system of claim 9, wherein a display of the following vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the following vehicle.

13. The communication system of claim 9, wherein the second vehicle comprises a plurality of following vehicles following the lead vehicle, and wherein each of the following vehicles comprises a second communication device for receiving the transmitted captured image data from said first communication device.

14. The communication system of claim 1, wherein an image processor disposed at the second vehicle processes the received transmitted captured image data for a driver assistance system of the second vehicle.

15. The communication system of claim 1, wherein a display disposed at the second vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the second vehicle.

16. A communication system for vehicles, said communication system comprising:

A plurality of cameras disposed at a first vehicle, wherein some of said cameras have a field of view exterior of the first vehicle and at least one of said cameras has a field of view interior of the first vehicle, said cameras capturing image data;

a first communication device disposed at the first vehicle, said first communication device wirelessly transmitting image data captured by said cameras;

a second communication device disposed at a second vehicle, said second communication device receiving the transmitted captured image data from said first communication device;

wherein said first and second communication devices comprise first and second dedicated short range communication devices;

wherein the first vehicle comprises a trailer and the second vehicle comprises a towing vehicle that is towing the trailer; and

wherein at least one of (i) an image processor disposed at the second vehicle processes the received transmitted captured image data for a driver assistance system of the second vehicle and (ii) a display disposed at the second vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the second vehicle.

17. The communication system of claim 16, wherein each of said first and second dedicated short range communication devices have a first channel dedicated for safety related communications and a second channel dedicated for communication of the captured image data.

18. A communication system for vehicles, said communication system comprising:

a camera disposed at a first vehicle and having a field of view exterior of the first vehicle, said camera capturing image data;

a first communication device disposed at the first vehicle, said first communication device wirelessly transmitting image data captured by said camera;

a second communication device disposed at a second vehicle, said second communication device receiving the transmitted captured image data from said first communication device;

wherein said first and second communication devices comprise first and second dedicated short range communication devices;

wherein the first vehicle comprises a lead vehicle of a platoon of vehicles and wherein the second vehicle comprises at least one following vehicle of the platoon of vehicles that is following the lead vehicle;

wherein said camera comprises a forward viewing camera of the first vehicle; and

wherein an image processor of the second vehicle processes the received transmitted captured image data for a driver assistance system of the second vehicle, and wherein said image processor processes the received transmitted captured image data for lane marker detection at the road ahead of the first vehicle.

19. The communication system of claim 18, wherein each of said first and second dedicated short range communication devices have a first channel dedicated for safety related communications and a second channel dedicated for communication of the captured image data.

20. The communication system of claim 18, wherein a display of the second vehicle displays images derived from the received transmitted captured image data for viewing by a driver of the second vehicle.
