Title:
VEHICLE BRAKE FLUID PRESSURE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/075032
Kind Code:
A1
Abstract:
A brake fluid pressure control device (U), wherein an electronic control device (200) comprises: a change amount calculation unit (220) for calculating an amount of change in wheel speed over time; a change amount determination unit (230) for determining whether the amount of change has a positive or negative sign; and an anti-lock brake control unit (260). During ongoing execution of a first decompression control, in which a braking force acting on a wheel brake is further reduced in a state where the braking force acting on the wheel brake has been reduced in an anti-lock brake control, if the amount of change is determined to be a positive value by the change amount determination unit (230), then the anti-lock brake control unit (260) stops the first decompression control. This configuration makes it possible to improve the feeling of braking.
