| AV control unit |
- It is the master unit of the MULTI AV system, and it is connected to each control unit by communication. It operates each system according to communication signals from the AV control unit.
- The AV control unit includes the audio, USB connection and vehicle status functions.
- It is connected to each control unit via CAN communication to obtain necessary information for the vehicle information function.
- It is receives a steering angle signal from the steering angle sensor via CAN communication and controls an expected course line during rear view monitor operation.
- It inputs the illumination signals that are required for the display dimming control.
- It inputs the signals for driving status recognition (vehicle speed, reverse and parking brake).
- TEL voice signal and voice guidance signal are input from TEL adapter unit.
- Camera image signal is received and transmitted to display unit.
|
| Display unit |
- Display image is controlled by the serial communication from AV control unit.
- It receives the power (signal VCC and inverter VCC) from the AV control unit and operates.
- RGB image signal is input from AV control unit (RGB image, RGB area and RGB synchronizing).
- Composite image signals are input from AV control unit.
- Synchronizing signal (HP, VP) is output to AV control unit.
|
| Active noise control unit |
- Generates an antiphase sound weakening interior engine booming noise, mixes the antiphase sound with a sound signal transmitted from the AV control unit, and transmits the mixed sound signal to each speaker.
- Input microphone signal from front/rear microphone (for active noise control system).
|
| Front door speaker |
- Outputs sound signal from active noise control unit.
- Outputs high, mid and low range sounds.
|
| Front door squawker |
- Outputs sound signal from active noise control unit.
- Outputs high and mid range sounds.
|
| Rear door speaker |
- Outputs sound signal from active noise control unit.
- Outputs high, mid and low range sounds.
|
| Front microphone (for active noise control system) |
Detects interior engine booming noise and transmits a sound signal picked up by the front microphone to the active noise control unit. |
| Rear microphone (for active noise control system) |
Detects interior engine booming noise and transmits a sound signal picked up by the rear microphone to the active noise control unit. |
| Multifunction switch |
- Operation panel is equipped with the centralized switch where audio and air conditioner, etc. operations are integrated.
- Connected with preset switch via cable, and operation signal is transmitted to AV control unit via AV communication.
- The disk ejection operating signal is performed by hardwire.
