Abstract

The present disclosure includes automated vehicles having optimized driving profiles including optimized speed profiles for execution between obstacles in consideration of economy of operation, and methods thereof.

Claims

1. An automated vehicle comprising:

a motor vehicle, and

an automated vehicle control system configured to perform automated operation of the vehicle on public roadways,

wherein the automated vehicle control system determines a transition distance between a current vehicle stop position and a subsequent vehicle stop position, and determines and executes a desired speed profile between the current vehicle stop position and the subsequent vehicle stop position based on the determined transition distance.

2. The automated vehicle of claim 1, wherein the automated vehicle control system determines the transition distance, and determines and executes the desired speed profile, without user interaction.

3. The automated vehicle of claim 1, wherein the desired speed profile is based on an economy profile.

4. The automated vehicle of claim 3, wherein the economy profile includes a profile of at least one of fuel consumption and generation of exhaust products.

5. The automated vehicle of claim 1, wherein determining the transition distance is performed based on data received from at least one of an on-vehicle camera, an on-vehicle radar system, an on-vehicle lidar system, a GPS system, and a navigation system.

6. The automated vehicle of claim 1, wherein the desired speed profile includes both acceleration and deceleration data points.

7. An automated vehicle comprising:

a vehicle chassis adapted for driven motion via a propulsion system; and

a means for controlling automated operation of the vehicle, wherein the means for controlling automated operation determines a transition distance between a current vehicle stop position and a subsequent vehicle stop position, and determines and executes a desired speed profile between the current vehicle stop position and the subsequent vehicle stop position based on the determined transition distance.

8. The automated vehicle of claim 7, wherein the desired speed profile is based on an economy profile.

9. The automated vehicle of claim 8, wherein the economy profile includes a profile of at least one of fuel consumption and generation of exhaust products.

10. The automated vehicle of claim 7, wherein the means for controlling is configured to determine the transition distance based on data received from at least one of an on-vehicle camera, an on-vehicle radar system, an on-vehicle lidar system, a GPS system, and a navigation system.

11. The automated vehicle of claim 7, wherein the desired speed profile includes both acceleration and deceleration data points.

12. A method of operation an automated vehicle, the method comprising:

determining a transition distance between a current vehicle stop position and a subsequent vehicle stop position,

determining a desired speed profile between the current vehicle stop position and the subsequent vehicle stop position based on the determined transition distance, and

executing the desired speed profile.

13. The method of claim 12, wherein the desired speed profile is based on an economy profile.

14. The method of claim 13, wherein the economy profile includes a profile of at least one of fuel consumption and generation of exhaust products.

15. The method of claim 12, wherein determining the transition distance is performed based on data received from at least one of an on-vehicle camera, an on-vehicle radar system, an on-vehicle lidar system, a GPS system, and a navigation system.

16. The method of claim 12, wherein the desired speed profile includes both acceleration and deceleration data points.

17. A method of controlling automated operation of a motor vehicle, the method comprising:

determining a transition distance between a current vehicle stop position and a subsequent vehicle stop position; and

determining and executing a desired speed profile between the current vehicle stop position and the subsequent vehicle stop position based on the transition distance.

18. The method of claim 17, wherein the determination of the transition distance, and determination and execution of the desired speed profile is performed without user interaction.

19. The method of claim 17, wherein the desired speed profile is based on an economy profile.

20. The method of claim 19, wherein the economy profile includes a profile of at least one of fuel consumption and generation of exhaust products.

21. The method of claim 17, wherein determination of the transition distance is performed based on data received from at least one of an on-vehicle camera, an on-vehicle radar system, an on-vehicle lidar system, a GPS system, and a navigation system.

22. The method of claim 17, wherein the desired speed profile includes both acceleration and deceleration data points.
