System Description

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 the 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.
• Camera control unit controls the direction and distance of the predicted course line according to the sensor
signal 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
it is equipped.
• Warning message under the rear view monitor display is described by AV control unit.

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 steering wheel rotation.
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 steering angle sensor signal.
