Single Buffered Angular Speed Measurement Method for Self-Calibration of Magnetoresistive Sensors

Automotive angle sensors with magnetoresistive (MR) technology are used for: steering angle, motor commutation, rotor and pedal positions, automotive wipers, brakes and air routing in ventilation systems. Self-calibration of MR sensors is performed by linear and harmonic compensation based on the angular speed of shafts measured by single buffered method.
