STEERING ANGLE SENSOR

STEERING ANGLE SENSOR
Purpose, Function
-
The steering angle sensor detects the steering angle and sends it to the start stop unit as a steering angle (absolute steering angle) signal.
NOTE:
-
The steering angle sensor is installed to vehicles with the adaptive front lighting system (AFS).
Construction
-
The steering angle sensor is located on the clock spring.
-
Consists of a sensor unit in which a photo transistor and LED are positioned opposite each other, and a slit disc which moves together with the steering wheel.
Operation
-
As the disc moves with the steering wheel operation, the LED light received by the photo transistor varies due to the slits on the disc.
-
The photo transistor reads the variation of the light and outputs the steering angle (absolute steering angle) signal to the start stop unit.
Fail-safe
-
