Camera Assistance Sonar Function
- Corner/center sensors are installed on front bumper and rear bumper. When an obstacle is detected while around view monitor is displayed, a sonar indicator display and buzzer sound notify the driver of the proximity of an obstacle. When an obstacle is detected while around view monitor is not displayed, around view monitor screen is displayed automatically, and then notification is similarly as per the display and buzzer sound.
- The warning buzzer output frequency changes among 4 levels (for rear center) or 3 levels (for front center and corner) according to the detection distance.
SYSTEM OPERATION DESCRIPTION
- Sonar control unit receives shift position signal from TCM and vehicle speed signal from ABS actuator control unit via CAN communication, and controls ON/OFF of sonar system.
- Sonar control unit transmits detection signal and detection distance signal to around view monitor via CAN communication, according to signal from corner/center sensor depending on conditions as shown in the following table. Around view monitor displays the applicable sonar indicator.
Sonar system operation condition Sonar operation Shift position Vehicle speed Obstacle Sonar indicator Buzzer R position Less than 10 km/h (6 MPH) Yes Detection status is displayed Yes D position Less than 10 km/h (6 MPH) Yes Detection status is displayed Yes P or N position Less than 10 km/h (6 MPH) Yes Detection status is displayed* None - 10 km/h (6 MPH) or more Yes Not displayed None * : Only when camera image is displayed.
- When sonar is OFF in "Settings", sonar OFF display is displayed. Sonar OFF display is a function that displays frame in orange on the 4 corners of vehicle icon on Birds-Eye view to notify user of sonar OFF status. When sonar is switched to OFF by "Settings", sonar OFF display is only displayed for rear side of vehicle icon
- Sonar control unit is equipped with diagnosis function. Corner/center sensor malfunction and sensor harness open circuit can be detected. Malfunction status is transmitted to around view monitor control unit. Sonar OFF status is displayed and notified to the user.
OBSTACLE DETECTION DISTANCE
- Sonar control unit switches output of sonar indicator in 3 stages according to obstacle detection distance from corner/center sensor.
- Sonar control unit switches output of sonar buzzer in 4 stages (for rear center) or 3 stages (for front center and corner) according to obstacle detection distance from corner/center sensor.
- Sonar control unit can change setting of obstacle detection distance in 4 stages.
- Sonar control unit can change setting of buzzer volume in 3 stages.

SONAR INDICATOR DISPLAY
- When around view monitor control unit receives detection signal and detection distance signal from sonar control unit, the around view monitor control unit displays the sonar indicator on front display.
- Around view monitor control unit changes display color and indicator blinking cycle according to detection distance.
Sonar indicator display color and blinking cycle
SONAR BUZZER OPERATION
- Sonar control unit receives detection signal from corner/center sensor and sounds buzzer.
- Sonar tone depends on detection position. (Front is approximately 1, 600 Hz and rear is approximately 2, 500 Hz.)
- Sonar buzzer cycle is changed in 4 stages according to the detection distance.
