Title:
圧力バランス化ＰＳＵピストンを有するブレーキ・バイ・ワイヤ・システム
Document Type and Number:
Japanese Patent JP7386928
Kind Code:
B2
Abstract:
An electro-hydraulic brake system includes a master cylinder (MC) fluidly coupled to an MC fluid passageway and configured to supply fluid into the MC fluid passageway in response to pressing force on a brake pedal. A pressure supply unit (PSU) includes an electric motor and a PSU piston disposed within a piston bore, the PSU piston is movable through the piston bore by the electric motor and divides the piston bore into a first chamber and a second chamber. A pedal feel emulator (PFE) includes a PFE piston movable through a PFE bore and separating an upper chamber from a lower chamber. Fluid is conveyed from the lower chamber of the PFE to the second chamber of the PSU in response to a compression of the PFE. The MC fluid passageway provides a fluid path from the master cylinder into the upper chamber of the PFE.
