| description | PROBLEM TO BE SOLVED: To provide a vehicle-wheel bearing device with sensors, even in a traveling state in which a vehicle speed is changing, capable of: obtaining the number of sensor output signals to be appropriately processed; reducing rolling element passing components contained in an estimated load value; and improving load estimation accuracy.SOLUTION: A vehicle-wheel bearing 100 comprises: sensors 20 for detecting load applied thereto; signal processing means 31 for processing an output signal S from the sensors to generate a signal vector; and load calculation processing means 32 for calculating load applied to a vehicle wheel on the basis of the signal vector. The signal processing means 31 includes: a sensor signal calculating unit 33 for calculating the signal vector on the basis of the sensor output signal S; and a rolling element cycle detecting unit 34 for detecting a cycle of a vibrational component Sdif, caused by traveling of a rotating element, and contained in the output signal S from each of the sensors. The sensor signal calculating unit 33 changes a calculation processing parameter n, used for calculation processing, according to the cycle detected by the rolling element cycle detecting unit 34. |
