Abstract

Examples of techniques for overlaying on an in-vehicle display road objects associated with potential hazards are disclosed. In one example implementation, a method may include: responsive to detecting a presence of a detected vehicle in proximity to the local vehicle, determining, by a processing device, a position of the detected vehicle, a speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; determining, by the processing device, whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle, overlaying, by the processing device, a warning indicium on the in-vehicle display.

First claim

What is claimed is:

1. A computer-implemented method for overlaying, on an in-vehicle display, road objects associated with potential hazards to a local vehicle, the method comprising:
detecting, by a processing device, a presence of a detected vehicle in proximity to the local vehicle based on a dedicated short range communication transmitted by the detected vehicle and received at the local vehicle;
responsive to detecting the presence of the detected vehicle in proximity to the local vehicle, determining, by the processing device, a position of the detected vehicle, a speed of the detected vehicle, and a time to the local vehicle of the detected vehicle;
determining, by the processing device, whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and
responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle, overlaying, by the processing device, an indicium on the in-vehicle display, wherein the in-vehicle display is a full display mirror that displays images in a first mode and is a mirror in a second mode, wherein the full display mirror displays an image captured by a camera associated with the vehicle when the full display mirror is in the first mode, wherein the image is an image external to the vehicle, and wherein the indicium is overlaid on the image captured by the camera and displayed on the in-vehicle display.

2. The computer-implemented method of claim 1 , wherein the indicium on the in-vehicle display is indicative of the potential hazard to the vehicle.

3. The computer-implemented method of claim 1 , wherein the indicium is one of a box overlaid around the detected vehicle, an arrow along a path of the detected vehicle, or a warning message.

4. The computer-implemented method of claim 1 , further comprising generating an audible signal to alert a driver of the local vehicle when the indicium is overlaid on the in-vehicle display.

5. The computer-implemented method of claim 1 , wherein the potential hazard is one of the detected vehicle being in a blind spot of the local vehicle, the detected vehicle rapidly approaching the local vehicle in an adjacent lane of the local vehicle, or the detected vehicle rapidly approaching the local vehicle in a shared lane of the local vehicle.

6. A system for overlaying on an in-vehicle display road objects associated with potential hazards to a local vehicle, the system comprising:
an in-vehicle display configured to display an image;
a positioning engine configured to
determine a position of the detected vehicle, a speed of the detected vehicle, and a time to the local vehicle of the detected vehicle responsive to detecting a presence of a detected vehicle in proximity to the local vehicle, and
determine whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and

an overlay engine configured to overlay an indicium on the in-vehicle display responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle,
wherein the indicium is selected from a plurality of indicia based at least in part on a severity of the potential hazard to the local vehicle, wherein the in-vehicle display is a full display mirror that displays images in a first mode and is a mirror in a second mode, wherein the full display mirror displays an image captured by a camera associated with the vehicle when the full display mirror is in the first mode, wherein the image is an image external to the vehicle, and wherein the indicium is overlaid on the image captured by the camera and displayed on the in-vehicle display.

7. The system of claim 6 , wherein the indicium on the in-vehicle display indicative of the potential hazard to the vehicle.

8. The system of claim 6 , wherein the indicium is one of a box overlaid around the detected vehicle, an arrow along a path of the detected vehicle, or a warning message.

9. The system of claim 6 , wherein the overlay engine is further configured to generate an audible signal to alert a driver of the local vehicle when the indicium is overlaid on the in-vehicle display.

10. The system of claim 6 , wherein the potential hazard is one of the detected vehicle being in a blind spot of the local vehicle, the detected vehicle rapidly approaching the local vehicle in an adjacent lane of the local vehicle, or the detected vehicle rapidly approaching the local vehicle in a shared lane of the local vehicle.

11. The system of claim 6 , wherein the detected vehicle is detected based on a signal received from a proximity sensor of the local vehicle.

12. The system of claim 6 , wherein the detected vehicle is detected based on a dedicated short range communication received from the detected vehicle.

13. A computer program product for overlaying on an in-vehicle display road objects associated with potential hazards to a local vehicle, the computer program product comprising:
a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by a processing device to cause the processing device to perform a method comprising:
detecting, by the processing device, a presence of a detected vehicle in proximity to the local vehicle based on a dedicated short range communication transmitted by the detected vehicle and received at the local vehicle;
responsive to detecting the presence of the detected vehicle in proximity to the local vehicle, parsing, by the processing device, the DSRC to extract a position of the detected vehicle and a speed of the detected vehicle;
determining, by the processing device, a time to the local vehicle of the detected vehicle based at least in part on the position of the detected vehicle and the speed of the detected vehicle;
determining, by the processing device, whether the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle based on the position of the detected vehicle, the speed of the detected vehicle, and a time to the local vehicle of the detected vehicle; and
responsive to determining that the detected vehicle, in proximity to the local vehicle, represents a potential hazard to the local vehicle, overlaying, by the processing device, an indicium on the in-vehicle display, wherein the in-vehicle display is a full display mirror that displays images in a first mode and is a mirror in a second mode, wherein the full display mirror displays an image captured by a camera associated with the vehicle when the full display mirror is in the first mode, wherein the image is an image external to the vehicle, and wherein the indicium is overlaid on the image captured by the camera and displayed on the in-vehicle display.

14. The computer program product of claim 13 , wherein the indicium on the in-vehicle display indicative of the potential hazard to the vehicle.

15. The computer program product of claim 13 , wherein the indicium is one of a box overlaid around the detected vehicle, an arrow along a path of the detected vehicle, or a warning message.

16. The computer program product of claim 13 , wherein the
