Title:
BRAKE CONTROL DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/044853
Kind Code:
A1
Abstract:
A control device 100 is provided with: a flow rate derivation part 143 for deriving a pressure-holding-valve flow rate on the basis of a WC pressure command value and a previous WC pressure command value; a differential pressure derivation part 144 for deriving a differential-pressure-valve differential pressure value so that the differential-pressure-valve differential pressure value increases with an increase in the difference obtained by subtracting the pressure-holding-valve flow rate from a pump-discharge flow rate; and a pressure-holding-valve processing part 145 for performing an aperture derivation process to derive a command aperture so that the command aperture decreases with an increase in the difference obtained by subtracting the WC pressure command value from the sum of an MC pressure value and the differential-pressure-valve differential pressure value, and driving a holding pressure valve 64 at the command aperture.
