ABSTRACT:
In detecting the time at which a rotating object passes a given angular position, a value range of an angular position sensor output signal which varies relatively rapidly with angular position acts as a trip threshold that, when exceeded, indicates the object has achieved the detected angular position. A relatively rapid change as a function of angular position is determined by reference to the functional dependence of the detection signal level on the angular position of the object. Assuming the sensor signal varies sinusoidally with the object's angular position, the ranges in which the level of the sensor output signal varies rapidly with angular position lie in the vicinity of the angular positions at which the sensor output signal crosses its own mean value, the threshold value being chosen near this mean value.
