System Operation Description
- Around view monitor control unit transmits the sonar operation signal via CAN communication to sonar control unit to control the operation of sonar indicator and sonar buzzer.
- Sonar control unit transmits the detection signal and detection distance signal via CAN communication to around view monitor control unit. Around view monitor control unit operates the applicable sonar indicator.
- When receiving a sonar operation signal from the around view monitor control unit, the sonar control unit converts the signal into a detection distance signal and transmits it to the AV control unit via CAN communication. When receiving the detection signal, the AV control unit activates the speakers via the BOSE speaker amp.
