Title:
ROTATION SPEED ESTIMATION DEVICE AND VIBRATION SUPPRESSION DEVICE
Document Type and Number:
Japanese Patent JP2008296702
Kind Code:
A
Abstract:
To enhance accuracy when the rotation speed of a wheel is estimated.
The rotation speed estimation device 31 is the one for presuming the rotation speed of the wheel 2 provided on a vehicle 1. The rotation speed estimation device 31 presumes the rotation speed of the wheel 2 based on a drive system model for modeling the drive system of the vehicle 1. Further, inertia of the vehicle 1 used when the rotation speed of the wheel 2 is estimated is corrected according to slip of the wheel 2. In this case, the inertia of the vehicle 1 is corrected by a ratio of rotation acceleration of the wheel 2 estimated on the condition that the wheel 2 is gripped and rotation acceleration of the wheel 2 obtained in the state that the wheel 2 is slipped.
