    Abstract: A brake control system has a proportioning valve for controlling distribution of fluid pressure to at least rear wheel cylinders with respect to the fluid pressure built-up in a master cylinder. The split point of the proportioning valve is variable depending upon load distribution between front and rear wheels and overall load applied on the vehicle. In order to perform braking pressure distribution control, a controller is provided for setting set pressure for the proportioning valve, which set pressure defining the split point of the proportioning valve. The controller is connected to load sensors monitoring load condition at front part and rear part of the vehicle. The controller received front part load indicative signal and a rear part load indicative signal from the load sensors to derive load distribution and overall load on the vehicle, and whereby derives the set pressure of the proportioning valve. When the actual braking pressure is maintained lower than the set pressure, the controller maintains a proportioning valve device inactive to distribute hydraulic braking pressure built-up by a master cylinder to respective wheel cylinders so that the braking pressure in the wheel cylinders increases at a rate substantially corresponding to increasing rate of the fluid pressure in the master cylinder. On the other hand, when the actual braking pressure becomes equal to or higher than the set pressure, the controller makes the proportioning valve active to distribute the braking pressure to the wheel cylinders so that the braking pressure in the wheel cylinder increases at a controlled rate relative to the pressure increasing in the master cylinder.

    Abstract: An electronic brake control system, according to the present invention, has a controller. The controller employs a memory which stores a table or map representing split point values relative to vertical displacement between the sprung mass and the unsprung mass of the vehicle. The split point data stored in the memory are determined in accordance with the unique spring characteristics of the specific vehicle to which the brake control system is applied. The controller derives a reference pressure corresponding to the split point and compares the reference pressure with an actual hydraulic braking pressure. When the actual braking pressure is lower than the reference pressure, the controller holds a proportioning valve device inactive so as to distribute hydraulic braking pressure built up in a master cylinder among individual wheel cylinders so that the braking pressure in the wheel cylinders increases at a rate matching the rate of increase of the fluid pressure in the master cylinder. On the other hand, when the actual braking pressure is equal to or greater than the reference pressure, the controller activates the proportioning valve so as to distribute the braking pressure to the wheel cylinders such that the braking pressure in the wheel cylinder increases at a controlled rate related to the rate of pressure increase in the master cylinder.
