With Rear View Monitor

STEERING ANGLE SENSOR SIGNAL CIRCUIT


WITH REAR VIEW MONITOR : Description

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