Generator unit magnetic transitions passage correcting process for position sensor of motor vehicle, involves moving detector heads along preset direction so that heads detect transitions to obtain logic signals with switching faces

摘要

The process involves finding a position of two variation faces (Fv1, Fv2) to select a reference logic electrical signal (5). Detector heads (6) are moved along a preset direction, so that the heads detect magnetic transitions to obtain logic signals (S1, S2) with switching faces corresponding to the positions of the variation faces. The logic signals are combined to obtain a logic electrical signal (St) corresponding to the signal (5). An independent claim is also included for a position sensor including a generator unit with variable magnetic field.
