Method and system for selectively activating a vehicle near field communication module
First Claim
1. A method of selectively activating a vehicle near field communication (NFC) module, the method comprising the steps of:
- receiving a first mobile device battery signal indicating that a battery power level of a mobile device is at or below a threshold battery power level;
in response to receiving the first mobile device battery signal indicating that the battery power level of the mobile device is at or below the threshold battery power level, changing the vehicle NFC module to an active mode;
receiving a second mobile device battery signal indicating that the battery power level of the mobile device is above the threshold battery power level; and
in response to receiving the second battery signal indicating that the battery power level of the mobile device is above the threshold battery power level, changing the vehicle NFC module to a sleep mode.

Abstract
A method and system for selective activation of a vehicle near field communication (NFC) module. The vehicle NFC module may be part of a vehicle communication and access system capable of initiating various vehicle functions, such as unlocking one or more doors of the vehicle or starting a motor or engine of the vehicle. With the method and system, a user'"'"'s mobile device can be used in lieu of a key or a key fob. In situations where the battery power level of the user'"'"'s mobile device is low, such that Bluetooth or the generation of an active NFC signal is unavailable, the vehicle NFC module is maintained in an active mode. In the active mode, the vehicle NFC module can initiate a connection with a passive mobile NFC target. Otherwise, depending on the battery level of the user'"'"'s mobile device, the vehicle NFC module is maintained in a standard sleep mode to save power.

11. A method of selectively activating a vehicle near field communication (NFC) module, the method comprising the steps of:
-
pairing a mobile device with a vehicle communication and access system; wirelessly transmitting a first mobile device battery signal to a remote server, wherein the first mobile device battery signal indicates that a battery power level of the previously paired mobile device is at or below a threshold battery power level; in response to wirelessly transmitting the first mobile device battery signal to the remote server, sending an activation signal from the remote server to change the vehicle NFC module from a standard sleep mode to an active mode; and when the previously paired mobile device is within a range of the vehicle NFC module and the vehicle NFC module is in the active mode, sending an NFC signal from the vehicle NFC module to a mobile NFC module of the previously paired mobile device to activate the vehicle communication and access system. - View Dependent Claims (12, 13, 14, 15)

16. A vehicle communication and access system comprising:
-
a control unit having a processor and memory, wherein the memory is configured to store a recognizable code for a previously paired mobile device; and a vehicle near field communication (NFC) device coupled to the control unit, wherein the control unit is configured to receive a first mobile device battery signal, the first battery power signal indicating that a battery power level of the previously paired mobile device is at or below a threshold battery power level, and in response to receiving the first mobile device battery signal indicating that the battery power level of the previously paired mobile device is at or below the threshold battery power level, the control unit is configured to change the mode of the vehicle NFC module from sleep to active. - View Dependent Claims (17)
