Title:
DISC BRAKE VIBRATION ESTIMATION METHOD AND DISC BRAKE VIBRATION ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/080261
Kind Code:
A3
Abstract:
A disc brake vibration estimation method includes a step of obtaining input physical amounts that are physical amounts about the disc rotor and the pad (step ST11), a step of estimating a vibration of the disc brake in an in-plane direction which is a circumferential direction of the disc rotor according to the obtained input physical amounts and a fluctuation in contact stiffness between the disc rotor and the pad (steps ST12 to 14), and a step of making a determination at least about squeal of the disc brake in the in-plane direction according to a displacement or a value derived from the displacement after a prescribed period from a start of estimation after the vibration of the disc brake is estimated (step ST15).
