Screen Configuration

OPERATION DESCRIPTION

Around view monitor screen transition

• Around view monitor is displayed when “CAMERA” switch is pressed, shift position is reverse, or when an obstacle is detected by the sonar system.

• Birds-Eye view, Front-side view, and front/rear wide view can be switched using the “CAMERA” switch.

• When the shift position is in any position other than reverse, around view monitor is cancelled:

  • approximately 3 minutes after “CAMERA” switch has been pressed.

  • when Nissan Ariya vehicle speed is approximately 6 MPH (10 km/h) or more (without OFF-ROAD mode or with OFF-ROAD mode, OFF-ROAD mode not selected).

  • when Nissan Ariya vehicle speed is approximately 12 MPH (20 km/h) or more (with OFF-ROAD mode, OFF-ROAD mode selected).

• Setting of Moving Object Detection (MOD) and sonar can be switched ON/OFF using the combination meter.

• In Birds-Eye view, an enhanced boundary is displayed on the image indicating the invisible area and clearly indicating the boundary of the 4 cameras. The invisible area is displayed in yellow when Birds-Eye view is displayed.

Front View

• When the selector lever is in any position other than reverse position, the front view is displayed by pressing the “CAMERA” switch. The front wide view function allows the display of an image with an approximately 180° horizontal angle.

• Nissan Ariya Vehicle width guiding line and vehicle distance guiding line in front view displays the predictive course line according to the steering angle.

• If the steering angle is within approximately 90 degrees, the predictive course lines on the left/right side are displayed. If the steering angle exceeds approximately 90 degrees, only the predictive course line on the outside (in the opposite side of steering direction) is displayed.

• Around view monitor control unit receives the steering angle signal from ABS actuator and electric unit (control unit) via CAN communication.

• Around view monitor control unit controls the direction of the predictive course line according to the steering sensor angle signal.

Front view guide lines

Rear View

• Moving Object Detection (MOD) is a function that notifies the driver of the presence of moving objects in the area around the Nissan Ariya vehicle. MOD detects moving objects using the camera image, illuminates the frame of view in yellow whenever the “MOD” icon is displayed in green, and sounds a buzzer.

• MOD detects moving objects while camera image is displayed on AV control unit.

• Around view monitor control unit performs the following process when moving objects are detected.

  • Superimposes yellow frame line on camera image signal and outputs them to AV control unit by LVDS.

  • Transmits MOD beep sound output request signal to combination meter via CAN communication.

• Around view monitor control unit detects moving objects from camera image according to an image recognition method called optical flow.

• MOD does not detect a background as a moving object when the Nissan Ariya vehicle moves (when whole screen moves), but detects a moving object when an actual moving object is displayed on screen.

• MOD can be set to permanent OFF using the Settings mode on the information display of the combination meter.

• Color of “MOD” icon indicates whether or not MOD is operative. “MOD” icon is displayed as shown in the following table. when MOD is operative, “MOD” icon is displayed in green. when MOD is not operative, “MOD” icon is displayed in gray. MOD icon is not displayed when MOD is OFF in “Settings”.

  View		Shift position
  		P or N position	D position	R position

  Rear wide view		—	—	Green
  Front wide view		Gray	Green	—

  ×: Icon is not displayed.

  —: View is not displayed in each shift position (P or N position, D position and R position).

• MOD illuminates frame of view in yellow and sounds buzzer, when any of the conditions in the following table are satisfied.

  Operation Condition		View where MOD is operative
