Abstract
Official abstract text for this publication.
A brake apparatus includes: a fluid pressure control valve; a fluid pressure pump; a feedback control circuit correcting a control power corresponding to a feedback control target rotation number of a motor and feed the corrected control power to a motor; a feed forward control circuit configured to feed, to the motor, a control power corresponding to a feed-forward control target rotation number of the motor; and an abnormal control fluid pressure generation control device, if a rotation number detector is abnormal, rotating the electric motor with the rotation number higher than the feedback control target rotation number by a margin rotation number, increases the brake fluid passing through the fluid pressure control valve, and changes the control current to be supplied to the fluid pressure control valve so that the wheel cylinder fluid pressure is not changed.
First claim
Opening claim text (preview).
What is claimed is: 1. A brake apparatus for a vehicle comprising: a master cylinder configured to generate a master cylinder fluid pressure corresponding to a brake operation; a wheel brake device that is provided for each wheel and configured to apply a braking force to the wheels as a brake fluid is supplied from the master cylinder to wheel cylinders; a fluid pressure control valve connected between the master cylinder and the wheel cylinders; a fluid pressure pump havin…
