摘要： A method for determining the angular position of a shaft of a motor vehicle. The method includes calculating the mean angular resolution; calculating the time at which the cosine signal passes through zero; using the time at which the sine signal passes through zero and the mean angular resolution; determining the measured angle at the calculated time at which the cosine signal passes through zero; calculating the amplitude of the second harmonic of the measured angle signa;, calculating a second-harmonic error from the calculated amplitude of the second harmonic; and calculating a compensated angle representing the corrected angular position of the shaft from the real-time measured angle and from the calculated second-harmonic error.
