Camera Assistance Sonar Function

• Sonar sensors are installed on rear bumper. When an obstacle is detected while Intelligent 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 Intelligent around view monitor is not displayed, Intelligent around view monitor screen is displayed automatically, and then notification is similar as while Intelligent around view monitor is displayed.
• Approaching distance between bumper and obstacle is displayed in 3 stages according to the color of the sonar indicator in display and blinking cycle of indicator.
• Warning by buzzer sound notifies distance to obstacle according to a 3-stage cycle.
• The sonar control unit output the buzzer sound.

System Operation Description 

• Sonar control unit receives shift position signal from transmission range switch and vehicle speed signal from combination meter via CAN communication, and controls ON/OFF of sonar system.
• Sonar control unit transmits detection signal and detection distance signal to Intelligent around view monitor via CAN communication, according to signal from corner sensor depending on conditions shown in the following table. Intelligent 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
  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 is displayed. Sonar OFF display is a function that displays frame in orange on the corners of vehicle icon on Birds-Eye view to notify user of sonar OFF status.
• Sonar control unit is equipped with diagnosis function. 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 to notified the user.

Obstacle Detection Distance 

• Sonar control unit changes output of sonar display and warning buzzers in 3 stages according to obstacle detection distance from corner sensors.
• Sonar control unit changes setting of obstacle detection distance in 4 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 AV control unit display.
• Around view monitor control unit changes display color and indicator blinking cycle according to detection distance.

Warning Buzzer Frequency 

• The warning buzzer cycle changes between 4 levels (for center) and 3 levels (for corner) according to the detection distance.
• The nearest sensor from the detected obstacle determines the buzzer cycle if multiple sensors detect an obstacle simultaneously.
