Title:
BRAKING CONTROL DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2023018223
Kind Code:
A
Abstract:
To provide a braking control device capable of quickly and reliably determining bottoming of a master piston.SOLUTION: A braking control device includes: a master cylinder having a master chamber partitioned by a mater piston; and a first pressure adjustment unit having a servo chamber positioned on opposite the master chamber relative to the master piston and generating a master pressure in the master chamber by supplying servo pressure to the servo chamber. The first pressure adjustment unit acquires the master pressure and the servo pressure and determines bottoming of the master piston based on comparison of the master pressure and the servo pressure. For example, the first pressure adjustment unit performs the comparison based on a pressure receiving area of the servo chamber and a pressure receiving area of the master chamber. In a configuration with the pressure receiving area of the servo chamber and the pressure receiving area of the master chamber being equal, the first pressure adjustment unit determines that bottoming has occurred when a difference between the servo pressure and the master pressure is equal to or more than a prescribed pressure.SELECTED DRAWING: Figure 6
