SYSTEMS AND METHODS FOR RAPID DETECTION OF ROTATION DIRECTION

摘要

Embodiments relate to sensor systems and methods for rapidly detecting a direction of rotation. In one embodiment, a sensor system is configured to identify positive and negative peaks of both speed and direction signals and to evaluate a sequential order of the peaks. A direction of rotation can be identified rapidly from the evaluation of the sequential order of peaks.

1. A method of detecting a direction of movement of a target comprising:
obtaining a first sensor signal related to movement of a target, the first sensor signal comprising a plurality of first signal maxima and first signal minima; obtaining a second sensor signal related to movement of the target, the second sensor signal comprising a plurality of second signal maxima and second signal minima; determining a sequence of occurrence of the first signal maxima, the first signal minima, the second signal maxima and the second signal minima; and determining a direction of movement of the target from the sequence of occurrence.
