VEHICLE BRAKING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/198818
Kind Code:
A1
Abstract:
This brake control device is provided with: a simulator which imparts an operating force to an operating member; a master unit including a master chamber connected to a wheel cylinder, and a servo chamber which imparts a forward force to a master piston; a pressure regulating unit which introduces a regulating hydraulic pressure into the servo chamber; a regenerative coordination unit which includes an input piston linked to the operating member, and which has an input chamber connected to the simulator by way of a simulator fluid path; a first open/closed valve which is provided in the simulator fluid path and which has an open position providing communication between the input chamber and the simulator, and a closed position isolating the input chamber and the simulator; and a controller which controls the first open/closed valve. The controller determines "whether or not an operation is sudden" on the basis of an operation amount, and when the sudden operation is denied, drives the first open/closed valve to the open position, and when the sudden operation is affirmed, drives the first open/closed valve to the closed position.
