Title:
HIGH RESOLUTION BEARING SENSOR AND IC CHIP FOR MULTIPOLE PAIR MAGNETIC PULSE RING
Document Type and Number:
WIPO Patent Application WO/2018/186556
Kind Code:
A1
Abstract:
A measurement sensor for measuring a rotational speed and direction of a magnetic encoder in a vehicle wheel may comprise: a first magnetic sensor configured to sense a magnetic field induced by the magnetic encoder and output a strength value of the magnetic field as a first electrical signal; a second magnetic sensor configured to sense the magnetic field induced by the magnetic encoder and output a strength value of the magnetic field as a second electrical signal; a first output signal generator for generating and outputting first rotational data including information indicating the rotational speed of the wheel on the basis of the first electrical signal; and a second output signal generator configured to generate second rotational data including information indicating the rotational speed of the wheel on the basis of the second electrical signal. The information indicating the rotational speed of the wheel in the second rotational data may have a higher resolution than the information indicating the rotational speed of the wheel in the first rotational data.
