Camera Assistance Sonar Function
- Install the corner sensor on the front bumper and rear bumper. It detects the obstacles around the vehicle when the around view monitor is displayed. It warns of the approach to the obstacles with the buzzer and indicator in the display linked with the around view monitor system.
- It displays the distance between the bumper and obstacle with the color of sonar indicator in the display and the blinking cycle of indicator in 3 stages.
- The buzzer warns of the distance to the obstacles with the cycle in 3 stages.
System Operation Description
- Around view monitor control unit transmits the sonar operation signal via AV communication to sonar control unit to control the operation of sonar indicator and sonar buzzer.
- Sonar control unit that receives the sonar operation signal from around view monitor control unit transmits the detection signal and detection distance signal according to the signal from corner sensor via AV 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 a signal transmitted from the corner sensor into a detection distance signal and transmits it to the AV control unit via AV communication. When receiving the detection signal, the AV control unit activates each speaker via BOSE amp.
- Sonar control unit has the diagnosis function. It can detect the corner sensor malfunction or sensor harness open circuit. It transmits the diagnosis results to around view monitor control unit and always displays the sonar indicator in red to inform the user.
Obstacle Detection Distance
- Sonar control unit changes the outputs of the sonar indicator and warning buzzer in 3 stages according to the obstacle detection distance from the corner sensor.
- The sonar control unit can change the setting of obstacle detection distance in 4 stages.
DETECTION DISTANCE SPECIFICATION
| Warning item | Sensitivity level 1 (Fastest warning) | Sensitivity level 2 (Faster warning) | Sensitivity level 3 (Default value) | Sensitivity level 4 (Slower warning) |
|---|---|---|---|---|
| First stage warning | 70 - 80 cm (27.5 - 31.4 in) | 60 - 70 cm (23.6 - 27.5 in) | 50 - 60 cm (19.6 - 23.6 in) | 40 - 50 cm (15.7 - 19.6 in) |
| Second stage warning | 50 - 70 cm (19.6 - 27.5 in) | 40 - 60 cm (15.7 - 23.6 in) | 30 - 50 cm (11.8 - 19.6 in) | 30 - 40 cm (11.8 - 15.7 in) |
| Third stage warning | Less than 50 cm (19.6 in) | Less than 40 cm (15.7 in) | Less than 30 cm (11.8 in) | Less than 30 cm (11.8 in) |
Sonar Indicator Display
- Around view monitor control unit that receives the detection signal and detection distance signal from sonar control unit displays the sonar indicator on display.
- Around view monitor control unit changes the color or blinking cycle of the indicator according to the detection distance.
Sonar Buzzer Operation
- Each sonar sensor transmits a sensor signal to the sonar control unit when detecting an obstacle.
- The sonar control unit converts a signal received from each sonar sensor into distance and transmits detection distance signal to the AV control unit via AV communication.
- The AV control unit transmits a buzzer signal to the BOSE amp. corresponding to each sonar sensor based on the received signal.
- When receiving a buzzer signal, the BOSE amp. transmits the buzzer signal to the each speaker. When each speaker receives a buzzer signal, a buzzer sounds.
- When the front corner sensor detects an obstacle, a buzzer is heard from the speakers on the front side.
- When the rear corner sensor detects an obstacle, a buzzer is heard from the speakers on the rear side.
- It changes the buzzer cycle in 3 stages according to the detection distance.
