Abstract

DC60 (06/09/55) To improve the abnormality of the crank pulse generator signal detection, which is a characteristic for the abnormality of the reluctor range accuracy, the reluctor 10 is arranged on the surrounding surface of the rotating object 8 such that the rotating yoke and the sensor 1 detect the reluctor 10 and output a pulse signal. The step cycle calculation part 66 calculates the cycle of the PLS pulse signal. The division 67 calibrates the cycle of the pulse signal using the calibration value. The calibration value is used to calculate the rotation variance of the rotating object 8. The calibration calculation part 61 outputs the actual measured value representing the selected reluctor range 10 based on the pulse signal interval corresponding to the previously selected reluctor 10. The reference storage section 63 outputs a reference value for the reluctor interval 10 based on the rotational speed of the rotating object 8. Division 64 calculates the ratio between the actual measured value and the reference value and calculates and outputs a calibration value using division 67.
