Abstract
An audio, video, and navigation (AVN) system includes a battery voltage detection circuit configured to detect an output voltage of a main battery; an e-call power controller configured to output power of a back-up battery (BUB) based on a result of detecting the output voltage; and a central controller configured to receive the power of the BUB and to generate an accident occurrence message when an airbag inflation signal is received.
