Title:
BRAKING CONTROL DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/078228
Kind Code:
A1
Abstract:
This braking control device comprises: a first adjustment unit that adjusts a hydraulic pressure generated by a first electric motor to a first hydraulic pressure; a "master unit having a master chamber, a servo chamber, and a reaction force chamber"; a "regenerative coordination unit in which a gap between a master piston and an input piston inside an input cylinder is controlled through the first hydraulic pressure"; a first opening/closing valve provided in a first fluid passage that connects the input cylinder and the reaction force chamber; a second opening/closing valve provided in a second fluid passage that connects the reaction force chamber and a reservoir; a reaction force hydraulic pressure sensor that detects the reaction force hydraulic pressure of the reaction force chamber; an input hydraulic pressure sensor that detects the input hydraulic pressure of the input cylinder; and a controller that controls the first electric motor, the first opening/closing valve, and the second opening/closing valve. The controller determines, on the basis of the reaction force hydraulic pressure and the input hydraulic pressure, the suitability of the master unit, the regenerative coordination unit, the first opening/closing valve, and the second opening/closing valve.
