Steering Angle Sensor: Description and Operation
STEERING WHEEL ANGLE SPEED SENSORDESCRIPTION
GENERAL DATA
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 MFS (Multi-Function Switch) under the steering wheel.
MEASURING PRINCIPLE
A non contact, analog angle sensor carrying out absolute measuring by the use of the Anisotropic-Magneto-Resistive effect (AMR). Measuring of the absolute angle by means of a toothed measuring gear with magnetic properties in combination with different ratios. Corresponding AMR elements that change their electrical resistance according to the magnetic field direction detect the angle position of the measuring gears. A micro-controller decodes the measured voltage signals after A/D converting with the help of a mathematical function. Output of the digital angle value and velocity via CAN-interface.
