Abstract:
Embodiments relate to predictive output switching threshold determination systems and methods for sensors, for example magnetic field sensors. In embodiments, at least one individual switching threshold is determined predictively, rather than reactively, for each tooth or pole of a ferromagnetic tooth or pole wheel, respectively. For example, in one embodiment, the number of teeth or poles is programmed, and an optimal threshold for each tooth or pole is determined during a rotation of the wheel. The determined optimal threshold for each tooth is then used for that tooth in at least one subsequent rotation of the wheel, with calibration optionally taking place in future subsequent rotations. Thus, in embodiments, thresholds are predictive for each individual tooth or pole rather than reactive to an adjacent tooth or pole.
