A wheel speed sensor mounted on a wheel bearing to detect a rotational speed of a wheel is provided. The wheel speed sensor according to an embodiment of the present disclosure may comprise: a housing having a sensing module provided therein; a first sensing module configured to detect a rotational speed of the wheel and to output a first detection signal to an outside; and a second sensing module configured to detect a rotational speed of the wheel independently of the first sensing module and to output a second detection signal to the outside. According to an embodiment of the present disclosure, the first sensing module may comprise a first sensing part configured to detect a rotational speed of the wheel, and the second sensing module may comprise a second sensing part configured to detect a rotational speed of the wheel.

Wheel speed sensor having multiple sensing units and wheel bearing comprising same

A wheel speed detection device according to one aspect of the present disclosure is installable on a wheel bearing which comprises an outer ring and an inner ring coupled to a rotating shaft and relatively rotated relative to the outer ring about the rotating shaft. The wheel speed detection device comprises a first target concentrically coupled to the rotating shaft, a second target disposed along an outer circumference of the inner ring, a cap coupled to the outer ring to cover the first target and the second target, a first sensor disposed in the cap and configured to detect a variation in magnetic field of the first target due to a rotation of the rotating shaft, and a second sensor disposed in the cap and configured to detect a variation in magnetic pole of the second target due to a rotation of the inner ring.

Device for detecting wheel speed

A sensor for measuring a rotation speed of a magnetic encoder includes a first magnetic detector detecting a magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a first electrical signal, a second magnetic detector detecting the magnetic field induced from the magnetic encoder and outputting a strength value of the magnetic field as a second electrical signal, a first output signal generator for generating and outputting first rotation data including information indicating a rotation speed of a wheel based on the first electrical signal, and a second output signal generator configured to generate second rotation data including information indicating a rotation speed of the wheel based on the second electrical signal. The information indicating the rotation speed in the second rotation data may have a higher resolution than the information indicating the rotation speed in the first rotation data.
