Abstract

The GPS-based vehicle alert and control system and method provides added fuel efficiency and safety for a global positioning system (GPS) equipped vehicle, such as an automobile, truck, airplane, boat or the like. In operation, the system receives a GPS signal to generate a set of vehicle position coordinates, which indicate the present location of the vehicle. A set of map data for a region about the vehicle position coordinates is then generated. Utilizing a constantly updated position of the vehicle, the system calculates a velocity of the vehicle and a projected path of the vehicle. At least one position in the projected path of the vehicle in which a change in the velocity of the vehicle is recommended is identified. The system generates an alert signal to the operator of the vehicle, which may be an auditory alarm or a visual alarm displayed on a display, including instructional information.

Claims

1. A GPS-based vehicle alert and control method, comprising the steps of:

receiving a GPS signal to generate a set of vehicle position coordinates;

generating a set of map data for a region about the vehicle position coordinates;

calculating a velocity of the vehicle and a projected path of the vehicle;

identifying at least one position in the projected path of the vehicle in which a change in the velocity of the vehicle is recommended; and

generating an alert signal to an operator of the vehicle.

2. The GPS-based vehicle alert and control method as recited in claim 1, further comprising the step of generating a visual map display using the set of map data.

3. The GPS-based vehicle alert and control method as recited in claim 2, further comprising the step of visually displaying on the visual map display the at least one position in the path of the vehicle requiring the change in the velocity of the vehicle, relative to the vehicle.

4. The GPS-based vehicle alert and control method as recited in claim 3, further comprising the step of providing navigational instructions to the operator of the vehicle.

5. The GPS-based vehicle alert and control method as recited in claim 4, further comprising the step of calculating a desired change in the velocity of the vehicle.

6. The GPS-based vehicle alert and control method as recited in claim 5, further comprising the step of selectively generating vehicle control signals for automatically changing the velocity of the vehicle.

7. The GPS-based vehicle alert and control method as recited in claim 6, further comprising the step of receiving a set of external condition data, the calculation of the desired change in the velocity of the vehicle being based upon a present velocity of the vehicle, the at least one position in the path of the vehicle requiring the change in the velocity of the vehicle relative to the vehicle, and the set of external condition data.

8. The GPS-based vehicle alert and control method as recited in claim 7, wherein the step of receiving external condition data includes receiving environmental-based data.

9. The GPS-based vehicle alert and control method as recited in claim 7, wherein the step of receiving external condition data includes receiving traffic-based data.

10. A GPS-based vehicle alert and control method, comprising the steps of:

receiving a GPS signal to generate a set of vehicle position coordinates;

generating a set of map data for a region about the vehicle position coordinates;

calculating a velocity of the vehicle and a projected path of the vehicle;

identifying at least one position in the projected path of the vehicle in which a change in the velocity of the vehicle is recommended;

calculating a desired change in the velocity of the vehicle; and

selectively generating vehicle control signals for automatically changing the velocity of the vehicle.

11. The GPS-based vehicle alert and control method as recited in claim 10, further comprising the step of generating an alert signal to an operator of the vehicle.

12. The GPS-based vehicle alert and control method as recited in claim 11, further comprising the step of generating a visual map display using the set of map data.

13. The GPS-based vehicle alert and control method as recited in claim 12, further comprising the step of visually displaying on the visual map display the at least one position in the path of the vehicle in which the change in the velocity of the vehicle is recommended, relative to the vehicle.

14. The GPS-based vehicle alert and control method as recited in claim 13, further comprising the step of providing navigational instructions to the operator of the vehicle.

15. The GPS-based vehicle alert and control method as recited in claim 14, further comprising the step of receiving a set of external condition data, the calculation of the desired change in the velocity of the vehicle being based upon a present velocity of the vehicle, the at least one position in the path of the vehicle in which the change in the velocity of the vehicle is recommended relative to the vehicle, and the set of external condition data.

16. The GPS-based vehicle alert and control method as recited in claim 15, wherein the step of receiving external condition data includes receiving environmental-based data.

17. The GPS-based vehicle alert and control method as recited in claim 15, wherein the step of receiving external condition data includes receiving traffic-based data.

18. A GPS-based vehicle alert and control system, comprising:

means for receiving a GPS signal to generate a set of vehicle position coordinates;

means for generating a set of map data for a region about the vehicle position coordinates;

means for calculating a velocity of the vehicle a path of the vehicle;

means for identifying at least one position in the projected path of the vehicle in which a change in the velocity of the vehicle is recommended; and

means for generating an alert signal to an operator of the vehicle.

19. The GPS-based vehicle alert and control system as recited in claim 18, further comprising means for generating a visual map display using the set of map data and visually displaying on the visual map display the at least one position in the path of the vehicle requiring the change in the velocity of the vehicle, relative to the vehicle.

20. The GPS-based vehicle alert and control system as recited in claim 19, further comprising:

means for calculating a desired change in the velocity of the vehicle; and

means for selectively generating vehicle control signals for automatically changing the velocity of the vehicle.
