Around View Monitor Function

This system is equipped with wide-angle high-resolution 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.
The sonar indicator is displayed on display (superimposed on the camera image) in combination with the camera assistance sonar system to warm of the approach of an obstacle.
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 and sonar indicator 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" and then it displays the sonar indicator on the "Birds-Eye view", "Front-Side view" "Rear wide view".
AV control unit renders the "Change View" switch, view icon, warning message on display.

Operation Description

Around view monitor operates by pressing the "CAMERA" switch of multifunction switch and shifting the selector switch 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 and rear wide view (rear only) 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.
ON/OFF setting of sonar indicator display on the Front-Side view screen can be performed.
In the Birds-Eye view, the invisible area is displayed on the image to specify the boundary of the 4 cameras. The invisible area is displayed in yellow in the Birds-Eye view after turning the ignition switch ON.
The sonar (both of buzzer and indicator) operates only when the camera screen is displayed.

NOTE: The first, second, and third camera image displayed when switched to the camera image display depends on the settings of "Camera View Priority".

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.
AV control unit is connected to the steering angle sensor and receives the steering angle signal via CAN communication. AV control unit is transmits steering angle signal to around view monitor control unit via AV communication.
Around view monitor control unit controls the direction and distance of the predictive course line according to the sensor signal from steering angle sensor.

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. The rear wide view function allows the display of an image with a 180° horizontal angle.
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 (except when using the rear wide view function).
The predictive course line is not displayed at the steering neutral position.
AV control unit is connected to the steering angle sensor and receives the steering angle signal via CAN communication. AV control unit is transmits steering angle signal to around view monitor control unit via AV communication.
Around view monitor control unit controls the direction and distance of predictive course line according to the sensor signal from steering angle sensor.

FRONT-SIDE VIEW

The front-side view image is from the side camera RH.
In Front-Side view, display the vehicle distance guiding line and vehicle width guiding line.
The infrared LED illumination is installed on the door mirror RH to illuminate around the front wheels.

BIRDS-EYE VIEW

The image from the 4 cameras is cut out and converted into the overhead view, and the surroundings of the vehicle is displayed in birds-eye view.
In Birds-Eye view, the invisible area is displayed on the image to specify the boundary of the 4 cameras.
The invisible area is displayed in yellow in the Birds-Eye view after turning the ignition switch ON as an information for the user. (OFF setting can be performed)

Camera Image Operation Principle

If the information writing to around view monitor control unit and the information from the camera are not matched, 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 from AV control unit via AV communication by pressing the "CAMERA" switch of multifunction 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, sonar indicator, and outputs them to the display unit.
