Abstract

A driver assistance system for a vehicle includes a plurality of lights linearly arranged substantially around an interior perimeter of the vehicle. A controller is controllably coupled to the plurality of lights, such that the controller is operable to control the plurality of lights. A hazard detection system is communicatively coupled to the controller. The controller includes a non-transitory computer readable medium storing instructions for causing the controller to illuminate at least one of the plurality of lights corresponding to a location of a hazard detected by the hazard detection system.

Claims

1. A driver assistance system for a vehicle comprising:

a plurality of lights linearly arranged around a majority of an interior perimeter of the vehicle;

a controller controllably coupled to the plurality of lights, such that the controller is operable to control the plurality of lights;

a hazard detection system communicatively coupled to the controller;

the controller including a non-transitory computer readable medium storing instructions for causing the controller to illuminate at least one of the plurality of lights corresponding to a location of a hazard detected by the hazard detection system; and

the non-transitory computer readable medium further including instructions for causing the controller to determine a worst case scenario position of a driver'"'"'s gaze based on the location of the identified hazard in response to the direction of the driver'"'"'s gaze being unknown, and for causing the controller to initiate a warning in a position farthest from the hazard.

2. The driver assistance system of claim 1, wherein the plurality of lights comprises a plurality of adjacent rows of lights.

3. The driver assistance system of claim 1, wherein each light in the plurality of lights is an LED light.

4. The driver assistance system of claim 1, further comprising a driver analyzer mounted in an interior of the vehicle and operable to detect a direction of a driver'"'"'s gaze, wherein the driver analyzer is communicatively coupled to the controller such that images detected by the driver analyzer are transmitted to the controller.

5. The driver assistance system of claim 4, wherein the driver analyzer is a camera.

6. The driver assistance system of claim 1, wherein the controller further comprises an infotainment system and wherein the plurality of lights are configured to display at least one of text and symbolic information received from the infotainment system.

7. The driver assistance system of claim 1, wherein the plurality of lights linearly arranged around the majority of the interior perimeter of the vehicle are a ring of lights that circumscribes the interior of the vehicle.

8. The driver assistance system of claim 7, wherein the ring of lights comprises at least one break.

9. A method for assisting a driver of a vehicle comprising the steps of:

identifying a hazard using a hazard detection system;

determining a worst case position of a driver'"'"'s gaze based on a location of the identified hazard in response to the direction of the driver'"'"'s gaze being unknown; and

illuminating at least one light of a plurality of lights linearly arranged around a majority of an interior perimeter of the vehicle in response to identifying the hazard, thereby indicating a location of the hazard to a driver, wherein the plurality of lights linearly arranged substantially around the interior perimeter of the vehicle at least substantially circumscribes the interior of the car.

10. The method of claim 9, wherein the step of illuminating at least one light comprises illuminating a plurality of lights sequentially thereby directing the driver'"'"'s attention toward the location of the hazard.

11. The method of claim 9, wherein a first illuminated light in the plurality of lights is a light located at a worst case scenario gaze position, and wherein

a final illuminated light in the plurality of lights is a light located in a position corresponding to the identified hazard zone.

12. The method of claim 9, further comprising the steps of identifying a direction of the driver'"'"'s gaze using a driver analyzer.

13. The method of claim 12, wherein the step of illuminating at least one light comprises illuminating a plurality of lights sequentially, thereby directing the driver'"'"'s attention toward the location of the hazard, and wherein the sequential illumination of lights begins with a light positioned in the driver'"'"'s gaze and ends with illumination of a light in a location corresponding to the location of the hazard.
