US 9,870,665 B2 · Apparatus, system and method for vehicle access and function control utilizing a portable device

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.

Dependent claims

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 (i) fob data relating to a key fob linked to the vehicle, (ii) device data comprising data relating to one or more devices that are authorized to access the vehicle, and (iii) vehicle access and/or function control data;
and
communications circuitry, operatively coupled to the processor, the communications circuitry configured to communicate with a new device is requesting access to the vehicle,
wherein the processor is configured to generate a secure fob key based on the fob data and the device data,
and wherein the processor is configured to generate a vehicle function control file based on the vehicle access and/or function control data and the secure fob key, wherein the vehicle function control file is configured to authenticate the new device with the vehicle via the secure fob key and to at least one of (i) limit access of the new device to the vehicle, (ii) limit an operational function of the vehicle, and (iii) provide alerts for the vehicle based on the vehicle access and/or function control data.
