Abstract

A vehicle-to-vehicle communication system providing a spatiotemporal look ahead and method thereof is provided. A trailing vehicle having a look ahead capability can communicate with a preceding vehicle. The preceding vehicle can measure a distance to a leading vehicle and provide that information through vehicle-to-vehicle communications to the trailing vehicle. The trailing vehicle can then display an augmented reality indicator above the vehicle through its head-up display indicating how far the leading vehicle is in front of the preceding vehicle. An icon representing the leading vehicle can be displayed within the augmented reality indicator representing the leading vehicle. Braking actions by the leading vehicle can be communicated to the trailing vehicle through the augmented reality indicator.

Claims

1. A method for representing an area in front of a vehicle on a trailing vehicle comprising:

connecting with the vehicle through vehicle-to-vehicle communications;

displaying an augmented reality indicator representing the area in front of the vehicle, wherein the augmented reality indicator is presented above the vehicle on the trailing vehicle and simulates a three-dimensional perspective of a road ahead of the preceding vehicle; and

displaying spatiotemporal information within the augmented reality indicator of a leading vehicle identified by the vehicle and communicated to the trailing vehicle through the vehicle-to-vehicle communications.

2. The method of claim 1, wherein connecting with the vehicle through the vehicle-to-vehicle communications comprises detecting the vehicle in front of the trailing vehicle.

3. The method of claim 1, wherein connecting with the vehicle through the vehicle-to-vehicle communications comprises opening the vehicle-to-vehicle communications with the vehicle in front of the trailing vehicle.

4. The method of claim 3, wherein connecting with the vehicle through the vehicle-to-vehicle communications comprises detecting the vehicle in front of the trailing vehicle through a camera.

5. The method of claim 1, wherein displaying the augmented reality indicator representing the area in front of the vehicle comprises showing an area unobstructed by the vehicle.

6. The method of claim 1, wherein displaying the spatiotemporal information within the augmented reality indicator of the leading vehicle identified by the vehicle and communicated to the trailing vehicle through the vehicle-to-vehicle communications comprises showing an indicator representing a distance between the preceding vehicle and the leading vehicle.

7. A look ahead system comprising:

a head-up display;

at least one processor; and

a memory operatively coupled to the processor, the memory storing program instructions that when executed by the processor, causes the processor to;

identify a vehicle;

receive information regarding a leading vehicle from the vehicle;

display an augmented reality indicator on the head-up display above the vehicle showing an area in front of the vehicle and an icon for the leading vehicle.

8. The look ahead system of claim 7, wherein the head-up display shows volumetric images.

9. The look ahead system of claim 7, wherein the augmented reality indicator is trapezoidal displaying information unobstructed by the vehicle.

10. The look ahead system of claim 7, wherein the information regarding the leading vehicle is positioned within the augmented reality indicator and changes positions dependent on a distance between the vehicle and the leading vehicle.

11. The look ahead system of claim 7, wherein the memory storing program instructions, when executed by the processor, causes the processor to display brake lights on the icon for the leading vehicle when brakes are applied by the leading vehicle.

12. The look ahead system of claim 7, wherein the memory storing program instructions, when executed by the processor, causes the processor to display a plurality of icons representing multiple vehicles.

13. The look ahead system of claim 7, wherein the augmented reality indicator on the head-up display is transparent.

14. A vehicle comprising:

a wireless communication module receiving information regarding an area in front of a preceding vehicle; and

a head-up display depicting an augmented reality indicator above the preceding vehicle and showing the information regarding the area in front of the preceding vehicle.

15. The vehicle of claim 14, wherein the information regarding the area in front of the preceding vehicle shows distances between the preceding vehicle and a leading vehicle.

16. The vehicle of claim 14, wherein the augmented reality indicator is transparent.

17. The vehicle of claim 14, wherein the augmented reality indicator is trapezoidal.

18. The vehicle of claim 14, wherein the augmented reality indicator shows a view unobstructed by the preceding vehicle.

19. The vehicle of claim 14, wherein the augmented reality indicators shows a plurality of vehicle icons.

20. The vehicle of claim 17, wherein the trapezoidal augmented reality indicator simulates a three-dimensional perspective of a road ahead of the preceding vehicle.
