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 (Mutil-Function Switch) under the steering wheel.
MEASURING PRINCIPLE
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 byte pulse from the steering angle sensor.
