Around View Monitor Function

This system is equipped with wide-angle cameras on the front and rear of the vehicle and on both right and left door mirrors. The images from front view, rear view, front-side view (RH side), and birds-eye view that shows the view from the top of the vehicle are displayed to monitor the vehicle surroundings.
Around view monitor control unit cuts out and expands the image received from each camera to create each view.
In front view and rear view, the vehicle width, distance lines and predictive course lines are superimposed and displayed. In front-side view, the vehicle distance guiding line and vehicle width guiding line are displayed.
The Birds-Eye view converts the images from 4 cameras into the overhead view and displays the status of the vehicle on display. The vehicle icon that are displayed on the Birds-Eye view display are rendered by around view monitor control unit.

Around View Monitor Screen

Around view monitor combines and displays the travel direction view and "Birds-Eye view", "Front-Side view".

Operation Description

Around view monitor operates by pressing the "CAMERA" switch or shifting the selector lever to the reverse position.
When the selector lever is in any position other than the reverse position, the screen is switched to the around view monitor by pressing the "CAMERA" switch.
The screen is switched to the around view monitor by shifting the selector lever to the reverse position.
In the around view monitor, Birds-Eye view, Front-side view can be switched by pressing the "CAMERA" switch.
The around view monitor is cancelled 3 minutes after pressing the "CAMERA" switch, and then the screen returns to the screen before displaying the around view monitor when selector lever is in a position other than the reverse position.
In the Birds-Eye view, the invisible area is displayed to show the border of 4 camera images. In addition, red fixed lines are displayed in 4 corners of the vehicle icon. After turning the ignition switch ON, the invisible area is highlighted with yellow and red fixed lines are blink only once.

FRONT VIEW

The front view image is from the front camera.
When the selector lever is in any position other than the reverse position, the front view is displayed by pressing the "CAMERA" switch. It improves the visibility of obstacles in front of the vehicle and helps driving by the images displayed from Birds-Eye view and Front-Side view.
Display the vehicle width guiding line and vehicle distance guiding line in front view and display 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 is exceeding 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 steering angle sensor via CAN communication, and controls the direction and distance of the predictive course line.
ON/OFF setting of predictive course line can be performed by CONSULT

REAR VIEW

The rear view image is from the rear camera.
When the selector lever is in the reverse position, the rear view is displayed. Backing and parking are improved by the images from Birds-Eye view and Front-Side view.
Display the vehicle width guiding line and vehicle distance guiding line in Rear view and display the predictive course line according to the steering angle.
The predictive course line is not displayed at the steering neutral position.
Around view monitor control unit receives the steering angle signal from steering angle sensor via CAN communication, and controls the direction and distance of the predictive course line.
ON/OFF setting of predictive course line can be performed by CONSULT

Camera Image Operation Principle

If the camera image calibration is incomplete, the applicable camera position is indicated as an error on the Birds-Eye view display. (Calibration operation is necessary when replacing each camera or when replacing around view monitor control unit.)
Around view monitor control unit receives the camera switch signal via CAN communication from AV control unit by pressing the "CAMERA" switch.
Around view monitor control unit that receives the camera switch signal supplies the power to each camera and inputs the camera image from each camera.
When the selector lever is in the reverse position, around view monitor control unit receives the reverse signal, supplies the power to each camera, and inputs the camera image from each camera.
Around view monitor control unit that receives the camera image signal from each camera cuts out the required screen for each view, superimposes the camera image, vehicle icon, guiding lines, and outputs them to the AV control unit.

Precautions for Vehicle Width Guide Line and Predictive Course Line Display on The Rear View Monitor Display Side distance guide lines and predictive course line on the display may be different from actual lines depending on vehicle conditions and road conditions.

PRECAUTIONS FOR ROAD CONDITIONS

Since guide lines and predictive course line are drawn based on the road, a different distance may be displayed if a protruding block is present nearby.

PRECAUTIONS FOR BLOCK

Since guide lines and predictive course line are drawn based on the road, a different distance may be displayed if a protruding block is present nearby.
