FIELD: methods of correction of angular error of absolute angular position sensor recording angular position of first shaft whose rotary motion is interrelated with rotation of second shaft.
SUBSTANCE: proposed method may be used for determination of angular position of internal combustion engine camshaft. Angular position sensor is just absolute angular position sensor. First angular position of second shaft is recorded during complete revolution of first shaft and angular position of first shaft is determined on basis of measurement. Then, respective output magnitude of absolute angular position sensor is compared with respective angular position of first shaft at retained misalignment obtained in the course of comparison. Then, each output magnitude of absolute angular position sensor is corrected for respective retained magnitude.
EFFECT: possibility of compensating angular error of absolute angular position sensor.
