Abstract

An apparatus and system for alerting a driver within an automotive vehicle is provided. An alerting device is disposed within the vehicle, which is configured to alert a driver. A controller is operable to activate the alerting device to produce an alert. A hazard detecting device is configured to detect a hazard. The controller is configured to activate the alerting device to produce the alert if the hazard detecting device detects a hazard. The alert is produced a predetermined reaction time period before a desired driver response. The controller is configured to determine a driver response time. The driver response time includes the time from the alert to an actual driver response. The controller is configured to alter the predetermined reaction time period based on the driver response time. A method for assisting a driver of a vehicle and a non-transitory machine-readable medium that provides instructions are also provided.

Claims

1. An apparatus for alerting a driver within an automotive vehicle, the apparatus comprising:

an alerting device disposed within the vehicle, the alerting device being configured to alert a driver;

a hazard detecting device communicatively coupled to the controller, the hazard detecting device being configured to detect a hazard,

wherein the controller is configured to activate the alerting device to produce the alert if the hazard detecting device detects a hazard, the alert being produced a predetermined reaction time period before a desired driver response, the controller configured to determine at least one driver response time, the driver response time including the time from the alert to an actual driver response, the controller being configured to alter the predetermined reaction time period based on the at least one driver response time.

2. The apparatus of claim 1, wherein the at least one driver response time includes a plurality of driver response times, wherein the controller is configured to calculate an average response time from the plurality of driver response times, the controller being configured to alter the predetermined reaction time period based on the average response time.

3. The apparatus of claim 2, wherein the controller is configured to increase the predetermined reaction time period if the average response time is longer than a desired response time.

4. The apparatus of claim 1, wherein the alerting device comprises at least one light.

5. The apparatus of claim 4, wherein the at least one light includes a plurality of lights linearly arranged substantially around an interior perimeter of the vehicle.

6. The apparatus of claim 5, the controller being configured to illuminate at least one of the plurality of lights corresponding to a location of the hazard detected by the hazard detecting device.

7. The apparatus of claim 6, wherein the apparatus 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.

8. The apparatus of claim 1, wherein the alerting device comprises at least one audio speaker, wherein the alert is an audio alert, the audio speaker being configured to produce the audio alert.

9. The apparatus of claim 1, wherein the alert is produced in at least one of the following locations:

a head up display visible to the driver on a windshield of the vehicle;

an instrument cluster located adjacent to a steering wheel;

a center area of a front instrument panel; and

trim lighting within the vehicle.

10. A driver assistance system for alerting a driver within an automotive vehicle, the driver assistance system comprising:

an alerting system disposed within the vehicle, the alerting system being configured to alert a driver;

a controller controllably coupled to the alerting system, the controller being operable to activate the alerting system to produce an alert; and

a hazard detection system communicatively coupled to the controller, the hazard detection system being configured to detect a hazard,

wherein the controller is configured to activate the alerting system to produce the alert if the hazard detection system detects a hazard, the alert being produced a predetermined reaction time period before a desired driver response, the controller configured to determine at least one driver response time, the driver response time including the time from the alert to an actual driver response, the controller being configured to alter the predetermined reaction time period based on the at least one driver response time.

11. The driver assistance system of claim 10, wherein the at least one driver response time includes a plurality of driver response times, wherein the controller is configured to calculate an average response time from the plurality of driver response times, the controller being configured to alter the predetermined reaction time period based on the average response time.

12. The driver assistance system of claim 11, wherein the controller is configured to increase the predetermined reaction time period if the average response time is longer than a desired response time.

13. The driver assistance system of claim 10, wherein the alerting system comprises at least one light.

14. The driver assistance system of claim 10, wherein the alerting system includes a plurality of lights linearly arranged substantially around an interior perimeter of the vehicle.

15. The driver assistance system of claim 14, the controller being configured to illuminate at least one of the plurality of lights corresponding to a location of the hazard detected by the hazard detection system.

16. The driver assistance system of claim 10, wherein the alerting system comprises at least one audio speaker, wherein the alert is an audio alert, the audio speaker being configured to produce the audio alert.

17. The driver assistance system of claim 10, wherein the alert is produced in at least one of the following locations:

a head up display visible to the driver on a windshield of the vehicle;

an instrument cluster located adjacent to a steering wheel;

a center area of a front instrument panel; and

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

identifying a hazard using a hazard detection system;

producing an alert if a hazard is identified by the hazard detection system, including producing the alert a predetermined reaction time period before a desired driver response;

determining a driver response time, the driver response time including the time from the alert to an actual driver response; and

altering the predetermined reaction time period if the driver response time determined is outside of a predetermined range.

19. The method of claim 18, wherein the driver response time is a first driver response time, the method further including determining at least one additional driver response time, the method further including calculating an average response time based on the first driver response time and the at least one additional driver response time, the step of altering the predetermined reaction time period including altering the predetermined reaction time period if the average response time is outside of a predetermined range.

20. The method of claim 19, wherein the step of altering the predetermined reaction time period includes increasing the predetermined reaction time period if the average response time is longer than the predetermined range.

21. The method of claim 18, wherein the step of producing an alert includes illuminating at least one light of a plurality of lights linearly arranged substantially around an interior perimeter of the vehicle, thereby indicating a location of the hazard to the 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.

22. The method of claim 21, wherein the step of producing the alert by illuminating at least one light comprises illuminating a plurality of lights sequentially thereby directing the driver'"'"'s attention toward the location of the hazard.
