PURPOSE: A vehicle body warning system for outputting the warning sound through the inner speakers of a vehicle using a vehicle communication is provided to offer the warning sound having a clean tone quality and enough sound pressure by generating the warning sound through the speaker of a vehicle not a buzzer. CONSTITUTION: A vehicle body warning system comprises a body control module(10), an audio module(20) and a speaker(30). The body control module receives a car state signal, a power signal and a rear sensor signal and determines the warning about all kinds of the states of a vehicle. The body control module transmits the warning signal through the vehicle inner communications protocol. The audio module receives the warning signal transmitted from the body control module. According to the priority, the audio module synthesizes the warning signal and audio signal. The audio module proceeds a D/A conversion and an amplification about the audio signal in which the sound equalizing effect unit is synthesized. The speaker reproduces the audio signal outputted from the audio module and offers the audio sound and the alarm to operator. |
