摘要： The rotation detection device includes: an encoder having to-be-detected patterns cyclically arranged in the circumferential direction; and a sensor configured to detect the to-be-detected patterns to generate pulses. The device further includes a reference pattern storage unit, a phase difference detection unit, and an error correction unit. The reference pattern storage unit measures pitch errors in the to-be-detected patterns prior to operation and stores the pitch errors as a reference pattern Pref. The phase difference detection unit determines a pitch error pattern Pm corresponding to one rotation of the to-be-detected patterns from rotation signals representing a plurality of rotations detected during operation, and performs comparison with a reference pattern Pref to determine a relative phase difference φ. Based on the phase difference φ obtained by the phase difference detection unit, the error correction unit corrects errors included in the rotation signals detected by the sensor.

摘要： A sensor-equipped wheel support bearing assembly is provided which performs high-accuracy load estimation without providing with another sensor, even in a state where a ground contact load on a wheel supported by the bearing is very low as compared to other wheels. The assembly includes: a plurality of sensor units (20) detecting a load on a wheel support bearing segment (100); sensor signal calculator (31) processing sensor signals (S) from the units; and load calculation processor (32) calculating a load on a road surface contact point on a wheel, based on the processed information. The processor (32) determines whether a target wheel is in a predetermined low load state, based on information of a detected load on a wheel other than the target wheel; and switches a load calculation scheme in accordance with a result of the determination to calculate a load on the wheel.
