Braking force distribution control system

摘要

An arrangement for controlling the braking force applied to a rear wheel in a certain relationship with a braking force applied to a front wheel so as to provide an ideal braking force distribution includes an auxiliary power source for discharging a power pressure and a dynamic hydraulic braking pressure regulator for regulating the power pressure to a pressure regulated in a certain relationship with the hydraulic braking pressure discharged from a master cylinder. Pressure control valves are disposed in a hydraulic circuit which communicates the pressure regulator with a rear wheel cylinder. The control valves control the hydraulic pressure in the rear wheel cylinder in a certain relationship with the hydraulic pressure in the front wheel cylinder.
