Steering Angle Sensor: Description and Operation
STEERING WHEEL ANGLE SPEED SENSORDESCRIPTION
The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses. The sensor is detached on the MPS(Multi-Function Switch) under the steering wheel.
OPERATION
The split of the steering angle sensor detects a steering angle of the steering wheel by a ON/OFF pulse caused by whether or not the LED lights go through the hole of the split, rotating as the steering wheel revolves.There are three LEDs, two(ST1, ST2) for detecting a steering direction, and the other for the neutral position.
The HECU calculates the steering angle by the pulse from the steering angle sensor.
