Title:
BRAKE CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2022040694
Kind Code:
A
Abstract:
To provide a brake control device in which bottoming of a piston can be avoided when a rapid wear of a friction member is generated.SOLUTION: A brake control device is equipped with "a pressure adjusting unit that moves a pressure adjusting piston with an electric motor and adjusts a braking fluid pressure in a wheel cylinder," "a displacement sensor that detects displacement corresponding amount corresponding to the displacement of the pressure adjusting piston," and "a controller that controls the electric motor on the basis of the displacement corresponding amount". The controller moves the pressure adjusting piston in first direction when boosting is instructed to increase the braking fluid pressure, does not move the pressure adjusting piston when holding is instructed to hold the braking fluid pressure, and moves the pressure adjusting piston in a second direction when decompression is instructed to decrease the braking fluid pressure. The controller moves the pressure adjusting piston in the second direction if the displacement corresponding amount becomes a predetermined displacement or more during one braking operation that is a period from the starting of energization to the electric motor to the finishing of energization, at least either one of when the boosting is instructed or when the holding is instructed.SELECTED DRAWING: Figure 5
