CAMERA IMAGE OPERATION PRINCIPLE
Power is supplied to rear view camera from camera control unit and the rear view camera outputs the cam-
era image to camera control unit when selector lever is set to reverse position and the reverse signal on
camera control unit is input.
Camera control unit superimposes the guiding line and predicted course line to the image from rear view
camera and outputs to display unit. In this case, the reverse signal is also input to AV control unit. Therefore,
AV control unit recognizes the selector lever as in the reverse position. And then AV control unit switches the
image displayed by the communication signal between AV control unit and display unit with the camera
image.
AV control unit outputs camera image signal that is inputted from camera control unit to display unit.
Camera control unit controls the direction and distance of predicted course line according to the sensor sig-
nal from steering angle sensor.
AV control unit determines whether rear view camera is equipped or not, based on the presence of camera
connection recognition signal. It switches to rear view monitor image at the time of reverse signal input when
rear view camera is equipped.

PREDICTED COURSE LINE OPERATION PRINCIPLE
Detection Of Steering Rotation Direction
Camera control unit detects the rotation direction of steering according to the phase difference of two pairs of
pulse signals (sensor signal 1 and sensor signal 2) input from steering angle sensor.
Detection Of Steering Neutral Position
The sensor signal 3 input from steering angle sensor is generated at 1 pulse per 1 rotation of the steering
wheel. Camera control unit detects the steering neutral position from this pulse.
Correction Of Steering Neutral Position
Camera control unit corrects the steering neutral position during driving according to the vehicle speed signal
and sensor signal.

AV CONTROL UNIT Image on display is transmitted to rear view monitor image by serial communi-
cation between AV control unit and display unit.
AV control unit recognizes the presence of camera system with camera con-
nection recognition signal.
DISPLAY UNIT Camera image signal is input from AV control unit.
Rear view monitor image is changed by serial communication from AV control
unit.
CAMERA CONTROL UNIT Camera image signal is input from rear view camera. Camera image signal is
output to AV control unit.
Power supply is transmitted to rear view camera.
Superimposes the guiding line and predicted course line to the camera image
that outputs to AV control unit.
Inputs the sensor signal from steering angle sensor, and then controls the pre-
dicted course line.
Camera control unit is connected via AV communication.
REAR VIEW CAMERA The image of vehicle rear view is transmitted to camera control unit.
It receives power supply from camera control unit and operates.
STEERING ANGLE SENSORSteering signal necessary for predicted course line control is transmitted to cam-
era control unit.
