Abstract

A method for parking an autonomous vehicle in a parking lot. The method comprises receiving primary data from a first source and receiving secondary data from a second source. The primary data may include information sufficient to identify a location for one or more of a plurality of parking spaces within the parking lot. The secondary data may include status identifier information for at least one of the plurality of parking spaces. The method includes using the primary data and the secondary data to identify at least one vacant parking space in the plurality of parking spaces, and occupying the at least one vacant parking space.

First claim

What is claimed is:

1. A computer-implemented method for parking an autonomous vehicle in a parking lot, the method comprising:
receiving, using one or more processors, primary data from a first source, the primary data including information sufficient to identify a location for a plurality of parking spaces within the parking lot;
receiving, using one or more processors, secondary data from a second source, the secondary data including status identifier information for at least one of the plurality of parking spaces, the status identifier information comprising both an occupancy status and a priority status;
using the primary data and the secondary data to identify, using one or more processors, at least one vacant parking space in the plurality of parking spaces and determining the autonomous vehicle is eligible to use a parking space having the priority status;
creating a trajectory to the at least one vacant parking space; and
parking the autonomous vehicle in the at least one vacant parking space.

2. The method according to claim 1 , comprising:
electing a selected vacant parking space from a plurality of vacant parking spaces identified using the primary data and the secondary data;
creating a trajectory to the selected vacant parking space.

3. The method according to claim 2 , comprising:
electing the selected vacant parking space based on a proximity of one or more of the plurality of vacant parking spaces to an existing planned path of the autonomous vehicle.

4. The method according to claim 1 , wherein the status identifier information comprises at least one of an occupancy status and a priority status for each of the plurality of parking spaces.

5. The method according to claim 1 , wherein the priority status comprises at least one of a handicap status, a reserved status, and a limited parking time status.

6. The method according to claim 1 , wherein the primary data comprises geographical map information indicating one or more parking space location within the parking lot.

7. The method according to claim 1 , wherein the primary data further comprises destination or points of interest information proximate to the plurality of parking spaces, and the step of using the primary data and secondary data to identify at least one vacant parking space comprises locating a vacant parking space in close proximity to a predetermined destination or point of interest.

8. The method according to claim 1 , further comprising communicating with at least one other vehicle within the parking lot.

9. The method according to claim 8 , wherein the at least one other vehicle is occupying one of the plurality of parking spaces.

10. The method according to claim 8 , wherein the at least one other vehicle is also searching for a vacant parking space.

11. The method according to claim 10 , further comprising:
coordinating entitlement to a vacant parking space with the at least one other vehicle.

12. The method according to claim 11 , wherein the entitlement is based on at least one of (a) priority arrival information, and (b) a status of an autonomous vehicle passenger.

13. The method according to claim 1 , further comprising:
using one or more sensors to communicate with vehicles occupying a parking space or moving vehicles within the parking lot; and
communicating with the second source to provide supplemental status identifier information for at least one of the plurality of parking spaces.

14. A computer-implemented method for coordinating parking between a plurality of autonomous vehicles in a parking lot, the method comprising:
determining, using one or more processors, a number and location of parking spaces within the parking lot;
receiving, using one or more processors, occupancy information for a plurality of the parking spaces;
coordinating, using one or more processors, an entitlement for at least one vacant parking space based on at least one of (a) priority arrival information, and (b) a status of an autonomous vehicle passenger; and
directing, using one or more processors, one of the plurality of autonomous vehicles to park in the at least one vacant parking space based on the entitlement.

15. The method according to claim 14 , further comprising:
receiving, using one or more processors, a priority status for at least one of the plurality of the parking spaces.

16. The method according to claim 15 , wherein the priority status comprises at least one of a handicap status, a reserved status, and a limited parking time status, and the step of coordinating the entitlement for at least one vacant parking space comprises determining, using one or more processors, whether one or more autonomous vehicle is eligible for a parking space having the priority status.

17. The method according to claim 16 , wherein the step of coordinating the entitlement for at least one vacant parking space comprises:
determining, using one or more processors, a time each autonomous vehicle arrived in the parking lot, and assigning each autonomous vehicle with a priority rank,
wherein the entitlement is based on a combination of the priority status of the parking space and the priority rank of the autonomous vehicle.

18. The method according to claim 14 , wherein the autonomous vehicles communicate directly with one another.

19. The method according to claim 14 , wherein the autonomous vehicles communicate with a remote server, and the step of coordinating the entitlement is performed using the remote server.
