Abstract
A system and method are provided for determining location information of a vehicle keyfob relative to an object. The system and method may include communicating with a primary device (e.g., a smartphone) having primary device authentication information with respect to the object, and receiving parameter information, such as keyfob authentication information, from the primary device.
Claims20
A keyfob operable to communicate with an object, said keyfob comprising:
- an antenna system configured to communicate wirelessly with the object, wherein said keyfob and the object are configurable to communicate wirelessly via a primary communication link;
- a controller operably coupled to said antenna system, said controller configured to receive one or more parameters from a remote device via a secondary communication link with the remote device, wherein the one or more parameters pertain to authentication with respect to the object;
- and
- said controller configured to direct the antenna system to transmit communications to the object via said primary communication link, said controller operable to authenticate with respect to the object based on the one or more parameters received from the remote device via the secondary link, whereby the object is operable to determine a location of said keyfob based on said communications from said keyfob.
1 more element
A method of facilitating operation of an object, said method comprising:
- communicating wirelessly with the object via a primary communication link between the object and a remote device,
- communicating wirelessly with a keyfob separate from the remote device;
- storing one or more parameters pertaining to the object;
- transmitting one or more parameters from the remote device to the keyfob, wherein the one or more parameters pertain to authentication with respect to the object;
- determining a location of the keyfob with respect to the object;
- authenticating the key fob with respect to the object based on the one or more parameters received from the remote device;
- and
- authorizing at least one of an object status and an object event based on the one or more parameters provided to the keyfob.
