Embodiment Construction

[0020] Before turning to the drawings, which illustrate the exemplary embodiments in detail, it is to be understood that the disclosure is not to be limited to the details or methodology set forth in the description or shown in the drawings. It is also to be understood that the terminology is for the purpose of description only and should not be regarded as limiting.

[0021] Referring generally to the drawings, there is shown a system and method for powering only a vehicle telephone module using battery backup power in the event that power from a vehicle's main electrical system is unavailable. Advantageously, a battery backup system for a vehicle phone module can be small, low voltage or relatively inexpensive. Advantageously, a battery backup system for a vehicle telephone module may allow transmission (e.g., automated emergency calls, data messages, text messages, etc.) issue.

[0022] now refer to figure 1 , the vehicle 100 includes a number of subsystems for user conv...

Abstract

A battery backup system for use with vehicle telematics electronics includes a phone module configured for operation by the vehicle telematics electronics. The system further includes a battery module configured to provide power to the phone module and a circuit configured to determine that backup power is needed. The circuit causes the battery module to provide the backup power to the phone module for completing a transmission via the phone module. The battery module can provide the backup power to the phone module without providing operating power to the vehicle telematics electronics.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to US non-provisional application number 12 / 965,729, filed December 10, 2010. The foregoing US non-provisional applications are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates generally to the field of vehicle telematics. The present disclosure more particularly relates to battery backup systems and methods for vehicle telephone systems. Background technique [0004] Some vehicles include phones that can make emergency calls in the event of a collision or other emergency. The electronics for such phones are traditionally powered by the vehicle's main electrical system (eg, the vehicle's main 14 volt battery and alternator, 12 volt battery, etc.). If a collision or other emergency event cuts power between the vehicle's main electrical system and the phone electronics, conventional telematics systems may not be abl...
