DESCRIPTION

GENERAL DATA

The steering angle speed sensor detects the angle of the steering wheel in order to which direction a user chooses.

MEASUREING 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.

STEERING ANGLE SENSOR (SAS) calibration

1. PURPOSE OF calibration

A. On vehicle control, an ESP analyzes the intention of the driver.
B. An ESP recognizes a steering angle which a driver rotates through the steering angle sensor.
