Apparatus, system and method for dynamic identification and key management for vehicle access
First Claim
1. A system for authorizing access to vehicle functions for a vehicle, comprising:
- a processor;
data storage, operatively coupled to the processor, the data storage configured to store fob data relating to a key fob linked to the vehicle, and device data comprising data relating to one or more devices linked to the key fob that are authorized to access the vehicle; and
communications circuitry, operatively coupled to the processor, the communications circuitry configured to receive an access request indicating that a new device is requesting access to the vehicle,wherein the processor is configured to transmit a challenge via the communications circuitry to one of the one or more devices that are authorized to access the vehicle and receive a response thereto,wherein the processor is configured to generate a secure fob key based on the response and transmit the secure fob key to the new device, wherein the secure fob key comprises limitation data for setting parameters on vehicle access,and wherein the processor is configured to authenticate the new device based at least in part on the secure fob key, wherein the new device is authorized to access the vehicle subject to the limitation data upon completion of the authentication.

Abstract
A system for providing dynamic access to a vehicle via a plurality of devices. A device and/or a server of an authentication network stored fob data relating to one or more key fobs linked to the vehicle, and device data that includes data relating to one or more devices that are authorized to access the vehicle. The vehicle receives an access request indicating that a new device is requesting access to the vehicle, whereupon a challenge may be transmitted to one or more of the authorized devices. The one or more devices may respond, granting access to vehicle functions. The vehicle and/or authentication network generate a secure fob key and access limitations based on the response and transmit the secure fob key to the new device. The new device may be authenticated to access vehicle functions subject to the limitation based at least in part on the fob key.

11. A method for authorizing access to a vehicle, comprising:
-
storing fob data in a data storage operatively coupled to a processor, wherein the fob data relates to a key fob linked to the vehicle; storing device data in the data storage, the device data comprising data relating to one or more devices linked to the key fob that are authorized to access the vehicle; receiving, via communications circuitry operatively coupled to the processor, an access request from the vehicle indicating that a new device is requesting access to the vehicle; transmitting a challenge via the communications circuitry to one of the one or more devices that are authorized to access the vehicle; receiving a response via the communications circuitry; generating, via the processor, a secure fob key based on the response and transmitting the secure fob key to the new device, wherein the secure fob key comprises limitation data for setting parameters for vehicle access; and authenticating the new device based at least in part on the fob key, wherein the new device is authorized to access the vehicle, subject to the limitation data, upon completion of the authentication. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A vehicle for authorizing access for vehicle functions for a new device, comprising:
-
a processor; data storage, operatively coupled to the processor, the data storage configured to store fob data relating to a key fob linked to the vehicle, and device data comprising data relating to one or more devices linked to the key fob that are authorized to access the vehicle; and communications circuitry, operatively coupled to the processor, the communications circuitry comprising antennas for detecting the presence of a user and configured to receive an access request from the new device requesting access to the vehicle, wherein the processor is configured to message the one or more devices that are authorized to access the vehicle, via an authorization network, that the access request from the new device has been made, wherein the communications circuitry is configured to receive a secure fob key for the new device based on a response to the message, the secure fob key comprising limitation data for setting parameters for vehicle access and wherein the processor is configured to authenticate the new device based at least in part on the secure fob key, wherein the new device is authorized to access a vehicle function subject to the limitation data upon completion of the authentication.
