Abstract
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.
Claims20
A magnetic speed sensor, comprising:
- a digital component configured to:
- estimate a zero crossing event based on a plurality of sensor signal samples;
- and
- output, to a control unit, a speed signal that is based on the estimated zero crossing event.
1 more element
A system, comprising:
- a sensor module configured to:
- estimate a zero crossing event based on a group of sensor signal samples,
- the group of sensor signal samples including a sensor signal sample with a value above a signal threshold, and a sensor signal sample with a value below the signal threshold;
- and
- provide, to a control unit, a speed signal that is based on the estimated zero crossing event.
2 more elements
A method comprising:
- identifying, by a digital component of a magnetic sensor, a zero crossing event based on a plurality of sensor signal samples;
- and
- outputting, by the digital component of the magnetic sensor, a signal that is based on the identified zero crossing event.
