Title:
BRAKE CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2019026013
Kind Code:
A
Abstract:
To provide a brake control device of a vehicle which can be improved in pressure regulation accuracy, in the brake control device of the vehicle having an accumulator.SOLUTION: A brake control device comprises: an accumulator for accumulating fluid pressure which is generated by a pressure accumulation electric pump; "an amplification unit having 'an amplification chamber which is constituted by including the accumulator, an amplification cylinder, and an amplification piston in which a valve body is formed, in which fluid pressure accumulated in the accumulator is regulated by the valve body, into which the regulated fluid pressure is introduced, and which regulates the fluid pressure of a wheel cylinder', and 'a pilot chamber located at a side opposite to the amplification chamber with respect to the amplification piston'"; "a pressure regulation unit which is constituted of a pressure regulation electric pump different from the pressure accumulation electric pump, and an electromagnetic valve, and regulates the fluid pressure of the pilot chamber by the pressure regulation electric pump and the electromagnetic valve"; a fluid pressure sensor for detecting the fluid pressure of the pilot chamber; and a controller for controlling the pressure regulation electric pump and the electromagnetic valve on the basis of a detection value of the fluid pressure sensor.SELECTED DRAWING: Figure 1
