Abstract

A vehicle-mountable system is provided for monitoring road surface defects. The system may include a detector to detect a surface defect in a road surface along which a vehicle is traveling. A positioning system may determine an instant location of the vehicle, and a repository may store a location of the surface defect with reference to the instant location. A controller unit may receive and compare the instant location with the location of the surface defect to identify an imminent surface defect encounter. The controller unit may also identify guidance instructions to minimize an effect of the imminent surface defect encounter. Finally, an interface may relay the guidance instructions to the vehicle.

Claims

1. A vehicle-mountable system for monitoring road surface defects, the system comprising:

a detector for detecting a surface defect in a road surface along which a vehicle is traveling;

a positioning system for determining an instant location of the vehicle;

a repository for storing a location of the surface defect with reference to the instant location;

a controller unit to receive and compare an instant location of the vehicle with the location of the surface defect to identify an imminent surface defect encounter, wherein the controller unit further determines guidance instructions to minimize an effect of the imminent surface defect encounter; and

an interface to relay the guidance instructions to the vehicle.

2. The system of claim 1, wherein the positioning system comprises a satellite-based positioning system.

3. The system of claim 1, wherein the interface further controls vehicle seatbelt tension as a function of the guidance instructions.

4. The system of claim 1, wherein the interface further controls vehicle suspension parameters as a function of the guidance instructions.

5. The system of claim 1, wherein the interface further generates signals intelligible to a driver of the vehicle.

6. The system of claim 5, wherein the signals intelligible to a driver of the vehicle comprise at least one of steering instructions and speed instructions.

7. The system of claim 1, wherein the detector further comprises a shock sensor for detecting and measuring an intensity of bumps on the road surface during vehicle travel.

8. The system of claim 7, wherein the repository further stores information relating to an intensity of a detected bump.

9. A method for monitoring road surface defects, the method comprising:

detecting a surface defect in a road surface along which a vehicle is traveling;

determining an instant location of the vehicle; and

storing the location of the detected surface defect with reference to the instant location.

10. The method of claim 9, further comprising:

monitoring an instant location of the vehicle;

comparing the instant location with the stored location of the detected surface defect to identify an imminent surface defect encounter;

identifying guidance instructions to minimize an effect of the imminent surface defect encounter; and

relaying the guidance instructions to the vehicle.

11. The method of claim 9, wherein determining the instant location comprises utilizing a satellite-based positioning system to determine the instant location.

12. The method of claim 10, wherein relaying the guidance instructions further comprises controlling vehicle seatbelt tension as a function of the guidance instructions.

13. The method of claim 10, wherein relaying the guidance instructions further comprises controlling vehicle suspension parameters as a function of the guidance instructions.

14. The method of claim 10, wherein relaying the guidance instructions further comprises generating signals intelligible to a driver of the vehicle.

15. The method of claim 14, wherein the signals intelligible to a driver of the vehicle comprise at least one of steering instructions and speed instructions.

16. A computer program product for monitoring road surface defects, the computer program product comprising:

a computer-usable medium having computer-usable program code embodied therein, the computer-usable program code comprising;
