Patent ID: 8880240

Claim:
A system for providing continuous time communications between a mobile device and a vehicle using Near Field Communications (NFC), said system comprising: an interface module in the vehicle, including an NFC chip and a charging pad, where the interface module wirelessly charges the mobile device when the mobile device is placed on the interface module, and where the interface module is configured to manage continuous, two-way NFC communications between the mobile device and the vehicle by detecting the presence of the mobile device within NFC range of the interface module, determining if the mobile device is authorized to communicate with the vehicle, verifying that the mobile device is still in close proximity to the interface module by performing a Packet Delivery Ratio (PDR) test, and determining that the mobile device is capable of interoperation with the vehicle by issuing a performance challenge including a computing task to be completed by the mobile device, and the computing task is varied randomly as the performance challenge is periodically repeated; and at least one vehicle feature which is controllable by the mobile device via the interface module.
