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 (built into sonar control unit) 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
- The around view monitor control unit transmits a sonar operating signal to the sonar control unit via AV communication to control the operations of the sonar indicator and sonar buzzer.
- When receiving a sonar operating signal from the around view monitor control unit, the sonar control unit transmits detection signals and detected distance signals to the around view monitor control unit via AV communication. The around view monitor control unit turns on the applicable sonar indicator.
- After receiving a sonar operation signal from the around view monitor control unit, the sonar control unit sounds its built-in buzzer according to detected distance signals received from each corner sensor.
- 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
| Warning item | Sensitivity level 1 (Faster warning) | Sensitivity level 2 (Default value) | Sensitivity level 3 (Slower warning) | Sensitivity level 4 (Slowest 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 sounds the built-in buzzer according to detected distance signals from each corner sensor.
- The buzzer cycle changes in 3 stages according to the detection distance.
