Abstract

Systems and methods for reducing latency in vehicle access requests are provided herein. An example method includes receiving a first vehicle access request from a user, determining a pre-authenticated status for the user based on authenticating the user in response to the first vehicle access request, determining a pre-authorized status for the user based on the determination of the pre-authenticated status, receiving a second first vehicle access request from the user, and granting access to the vehicle when the user has the pre-authenticated status. Access to the vehicle can be conditioned upon the pre-authorized status of the user.

First claim

What is claimed is:

1. A system, comprising:
an access point of a vehicle that is configured to receive a request from a user to unlock a vehicle door;
an authorization management module that is configured to:
receive the request from the access point of the vehicle;
manage a pre-authorization status for the user as authenticated by the vehicle, the pre-authorization status being predicated a pre-authenticated status of the user;
verify user permissions related to the access point; and
output an authorization acknowledgement that confirms requests for which the user has been pre-authorized, the authorization acknowledgement being transmitted to the access point; and
an authentication management module that is configured to manage the pre-authenticated status for the user, the pre-authenticated status being predicated on an initial authentication of the user, wherein the authentication management module also receives the authorization acknowledgement from the authorization management module.

2. The system according to claim 1 , wherein the authentication management module and the authorization management module cooperatively determine that the user has the pre-authorized status and the pre-authenticated status prior to receiving the request.

3. The system according to claim 1 , further comprising a communication module that is configured to:
determine the initial authentication of the user; and
transmit the initial authentication of the user to the authentication management module, as well as a location of an entry device used by the user, wherein the entry device is used to provide the request to unlock the vehicle door to the access point.

4. The system according to claim 3 , wherein the entry device comprises a mobile device or a key fob.

5. The system according to claim 3 , wherein the entry device comprises a door access panel.

6. The system according to claim 1 , wherein the authorization management module is configured to cancel the pre-authorized status of the user when a presence of the user is no longer detected.

7. The system according to claim 1 , wherein the authentication management module is configured to cancel the pre-authenticated status of the user after a period of time.

8. The system according to claim 1 , wherein the authentication management module transmits to the authorization management module a trip identifier, a channel that is indicative of the access point, and privilege of the user, the privilege being indicative of a role for the user.

9. The system according to claim 1 , further comprising a body control module that controls locking and unlocking of the vehicle door.

10. The system according to claim 9 , wherein the body control module causes unlocking of the vehicle door in response to the authorization acknowledgement.

11. A device, comprising:
a processor; and
a memory for storing instructions, the processor executing the instructions to:
receive a vehicle access request from a user via an access point of a vehicle;
determine that the user has a pre-authenticated status and a pre-authorized status, wherein the user has the pre-authenticated status when the user has been previously initially authenticated and the pre-authenticated status has been granted, further wherein the pre-authorized status is determined prior to receiving the vehicle access request; and
grant access to the vehicle when the user has a pre-authenticated status and pre-authorized status.

12. The device according to claim 11 , wherein the processor is configured to determine an initial authentication status of the user prior to receiving the vehicle access request.

13. The device according to claim 11 , wherein the pre-authorized status allows the user to lock or unlock a door, unlock a cargo door or lift gate, trigger a panic mode of the vehicle, open or close a sliding door, start an engine of the vehicle, or any combination thereof.

14. The device according to claim 11 , wherein the processor generates a trip identifier, a channel, and a privilege level for the user that is indicative of privileges associated with the pre-authorized status, the channel being indicative of the access point.

15. A method, comprising:
receiving a first vehicle access request from a user;
determining a pre-authenticated status for the user based on authenticating the user in response to the first vehicle access request;
determining a pre-authorized status for the user based on the determination of the pre-authenticated status;
receiving a second vehicle access request from the user; and
granting access to the vehicle when the user has the pre-authenticated status in response to the second vehicle access request, wherein access to the vehicle is conditioned upon the pre-authorized status of the user.

16. The method according to claim 15 , further comprising canceling the pre-authorized status of the user when a presence of the user is no longer detected.

17. The method according to claim 15 , further comprising canceling the pre-authenticated status of the user after a period of time.

18. The method according to claim 15 , wherein the pre-authorized status allows the user to lock or unlock a door, unlock a cargo door or lift gate, trigger a panic mode of the vehicle, open or close a sliding door, start an engine of the vehicle, or any combination thereof.

19. The method according to claim 15 , wherein the pre-authorized status is based on a privilege of the user.

20. The method according to claim 15 , further comprising determining when the first vehicle access request or the second vehicle access request is an approach-based request or a passive entry request.
