Title:
VEHICLE-WHEEL BEARING DEVICE WITH SENSOR
Document Type and Number:
WIPO Patent Application WO/2014/002820
Kind Code:
A1
Abstract:
A vehicle-wheel bearing device with a sensor according to the present invention has a vehicle-wheel bearing (100) equipped with a plurality of sensors (20) for detecting a load applied thereto, and is provided with a signal processing means (31) for generating a signal vector by processing an output signal from the sensors, and a load-calculation processing means (32) for calculating the load applied to a vehicle wheel on the basis of the signal vector. The load-calculation processing means (32) has: a coefficient-conversion processing unit (33) for calculating an actual-load-estimation coefficient (MC), which is the load-estimation coefficient during actual attachment to a vehicle, on the basis of a standard-load-estimation coefficient (MB), which is the standard load estimation coefficient of a prescribed bearing (100); and a load calculation unit (34) for calculating the load applied to the wheel on the basis of the signal vector and the actual-load-estimation coefficient (MC) calculated by the coefficient-conversion processing unit (33).
