Abstract

A method for autonomously navigating a subject vehicle from among a plurality of vehicles in an environment includes determining whether the subject vehicle is to be moved from a first post-production location to a second post-production location within the environment based on transportation scheduling data associated with the subject vehicle. The method includes executing a navigation routine in response to the transportation scheduling data indicating the subject vehicle is to be moved. The navigation routine includes obtaining location data associated with the plurality of vehicles, identifying a vehicle path for the subject vehicle based on the location data of the plurality of vehicles, the first post-production location, the second post-production location, or a combination thereof, and instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location.

First claim

What is claimed is:

1. A method for autonomously navigating a subject vehicle from among a plurality of vehicles in an environment, the method comprising:
determining whether the subject vehicle is to be moved from a first post-production location to a second post-production location within the environment based on transportation scheduling data associated with the subject vehicle, wherein the transportation scheduling data associates the subject vehicle with a departure time from the environment, a departure location from the environment, and a default vehicle path to the second post-production location; and
executing a navigation routine in response to the transportation scheduling data indicating the subject vehicle is to be moved, wherein the navigation routine includes:
obtaining image data associated with the plurality of vehicles;
determining an image-based location of each of the plurality of vehicles based on a difference between the image data and one or more reference images that are tagged with predetermined location information;
identifying a vehicle path for the subject vehicle based on the image-based location of the plurality of vehicles, the default vehicle path to the second post-production location, the first post-production location, and the second post-production location; and
instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location.

2. The method of claim 1 further comprising:
capturing image data of the environment from one or more imaging sensors disposed within the environment; and
determining whether an object is present between the first post-production location and the second post-production location based on the image data,
wherein identifying the vehicle path for the subject vehicle is further based on a location of the object in response to the object being present between the first post-production location and the second post-production location.

3. The method of claim 2 , wherein the one or more imaging sensors are disposed on at least one of the plurality of vehicles.

4. The method of claim 1 , wherein instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location further comprises transmitting the vehicle path to the subject vehicle to have the subject vehicle autonomously travel to the second post-production location.

5. The method of claim 1 , wherein instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location further comprises remotely controlling an operation of the subject vehicle.

6. The method of claim 1 , wherein identifying the vehicle path based on the second post-production location further comprises:
selecting a parking space from a plurality of parking spaces at the second post-production location based on an availability of the plurality of parking spaces and the departure time associated with the subject vehicle; and
defining the vehicle path from the first post-production location to the selected parking space.

7. A method for autonomously navigating a subject vehicle from among a plurality of vehicles in an environment, the method comprising:
determining whether the subject vehicle is to be moved from a first post-production location to a second post-production location within the environment at a departure time from the environment based on transportation scheduling data associated with the subject vehicle, wherein the transportation scheduling data associates the subject vehicle with the departure time, a departure location from the environment, and a default vehicle path to the second post-production location, and wherein the second post-production location includes a plurality of parking spaces;
obtaining image data from one or more imaging sensors disposed within the environment and location data associated with the plurality of vehicles;
selecting a parking space from among the plurality of parking spaces based on the image data;
determining an image-based location of each of the plurality of vehicles based on a difference between the image data and one or more reference images that are tagged with predetermined location information;
defining a vehicle path based on the parking space, the image-based location, and the default vehicle path to the second post-production location; and
at the departure time for the subject vehicle, instructing the subject vehicle to autonomously travel along the vehicle path.

8. The method of claim 7 further comprising determining whether an object is present between the first post-production location and the second post-production location based on the image data, wherein identifying the vehicle path for the subject vehicle is further based on a location of the object in response to the object being present between the first post-production location and the second post-production location.

9. The method of claim 7 , wherein the one or more imaging sensors are disposed on infrastructure elements within the environment.

10. The method of claim 7 , wherein instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location further comprises transmitting the vehicle path to the subject vehicle to have the subject vehicle autonomously travel to the second post-production location.

11. The method of claim 7 , wherein instructing the subject vehicle to autonomously travel along the vehicle path to the second post-production location further comprises remotely controlling an operation of the subject vehicle.

12. The method of claim 7 , wherein identifying the vehicle path based on the second post-production location further comprises:
selecting the parking space based on an availability of the plurality of parking spaces and the departure time.

13. A system for autonomously navigating a subject vehicle from among a plurality of vehicles in an environment, the system comprising:
one or more image sensors disposed within the environment;
a controller communicably coupled to the one or more image sensors and the plurality of vehicles, wherein the controller is configured to execute a navigation routine at a departure time, wherein during the navigation routine, the controller is configured to:
determine whether the subject vehicle is to be moved from a first post-production location to a second post-production location within the environment at the departure time from the environment based on transportation scheduling data associated with the subject vehicle, wherein the transportation scheduling data associates the subject vehicle with the departure time, a departure location from the environment, and a default vehicle path to the second post-production location, and wherein the second post-production location includes a plurality of parking spaces;
obtain image data from the one or more imaging sensors;
determine an image-based location of each of the plurality of vehicles based on a difference between the image data and one or more reference images that are tagged with predetermined location information;
select a parking space from among the plurality of parking spaces based on the image data;
define a vehicle path based on the parking space, the image-based location, and the default vehicle path to the second post-production location; and
instruct the subject vehicle to autonomously travel along the vehicle path to the post-production location at the departure time.

14. The system of claim 13 , wherein the controller is configured to:
select the parking space based on an availability of the plurality of parking
