| 摘要 |
The present invention is directed to a front-rear braking force distribution control system for a vehicle. The system includes a wheel brake cylinders operatively associated with front and rear wheels of the vehicle, a pressure generator for pressurizing brake fluid in response to operation of a brake pedal to generate a hydraulic braking pressure and supply it to each of the wheel brake cylinders, and a pressure control device disposed between the pressure generator and the wheel brake cylinders for controlling the braking pressure in each of the wheel brake cylinders. A pressure sensor is provided for detecting the braking pressure generated by the pressure generator, and the detected braking pressure is compared with a predetermined threshold pressure. The braking force control device provides conditions for beginning the front-rear braking force distribution control, including at least a condition for beginning the front-rear braking force distribution control, when the detected braking pressure exceeds the predetermined threshold pressure, which may be set in accordance with a pressure increasing rate of the braking pressure.
