摘要:
A magnetic speed sensor may comprise a digital component configured to estimate a zero crossing event based on a plurality of sensor signal samples. The digital component may output, to a control unit, a speed signal that is based on the estimated zero crossing event.
摘要:
In various embodiments, a method may include: generating at least one time stamp based on detection of at least a first magnetic field event of at least one pole of a magnetic object during a first rotation; determining a model of the magnetic object based on the at least one time stamp, wherein the model describes a magnetic pattern caused by the first rotation of the magnetic object; generating at least one further time stamp based on detection of at least a second magnetic field event of the at the least one pole of the magnetic object during a second rotation; and updating the model based on the at least one further time stamp.
