Electrohydraulic braking system with remote booster

摘要

A brake system (10) comprising: a master cylinder (20) including a primary (24) and a secondary (26) chamber and a reservoir (26); an accumulator (40), a pump (42) having first inlet port connected to a reservoir (26) of the master cylinder (20) and the second outlet port (b) connected to the accumulator (40), a motor (50) for selectively driving the pump as a function of system pressure, a pressure boost mechanism (60) connected to the accumulator (40) and the primary and secondary chambers of the master cylinder for generating a boosted pressure at a fixed multiple of the pressure in either the primary or secondary master cylinder chambers.
