Braking force distribution control system
First Claim
1. A braking force distribution control system for controlling a braking force applied to a pair of rear wheels of an automotive vehicle in a certain relationship with a braking force applied to a pair of front wheels of said automotive vehicle, comprising:
- a pair of front wheel brake cylinders, each of which is operatively connected to a respective one of said front wheels for applying a braking force to the respective front wheel;
a pair of rear wheel brake cylinders, each of which is operatively connected to a respective one of said rear wheels for applying a braking force to the respective rear wheel;
a reservoir for storing brake fluid;
a master cylinder for pressurizing the brake fluid fed from said reservoir and supplying hydraulic braking pressure to said pair of front wheel brake cylinders in response to depression of a brake pedal;
an auxiliary power source communicated with said reservoir for pressurizing the brake fluid fed from said reservoir and discharging a power pressure;
dynamic hydraulic braking pressure regulating means communicated with said auxiliary power source for regulating said power pressure to a pressure regulated in a certain relationship with the hydraulic braking pressure discharged from said master cylinder in response to depression of said brake pedal;
pressure control valve means disposed in respective hydraulic circuits communicating said regulating means with said rear wheel brake cylinders for controlling the hydraulic braking pressure in said rear wheel brake cylinders; and
control means for actuating said valve means to control the hydraulic braking pressure in said rear wheel brake cylinders in a certain relationship with the hydraulic braking pressure in said front wheel brake cylinders.

Abstract
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.
