CAMERA IMAGE SIGNAL CIRCUIT (REAR VIEW CAMERA TO CAMERA
CONTROL UNIT)

Description

INFOID:0000000001558879

• Camera control unit outputs camera ON signal to rear view camera and inputs rear view camera image sig-

nal from rear view camera when the reverse signal is input.  

• The camera control unit that inputs the camera image signal transmits the camera image signal to the dis-

play unit.

STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT

STEERING ANGLE SENSOR SIGNAL 1, 2 CIRCUIT

Description

INFOID:0000000001558889

• Steering angle sensor signal 1, 2 detects the turning direction and quantity of the steering and transmits it to

the camera control unit.

• Steering angle sensor signal 3 detects the neutral position of the steering and transmits it to the camera con-

trol unit.

• Camera control unit performs the correction of neutral position with sensor signal 1, 2, 3 and vehicle speed

signal.
