摘要： The present invention is directed to a braking control system for controlling a braking force applied to each wheel of a vehicle. A steep slope detector GD is provided for determining whether the vehicle is on a steep slope, when the rear end of the vehicle is located downward. The wheel speeds of rear wheels RR, RL are held to be zero by a stop holding device SH which is adapted to supply the hydraulic braking pressure discharged from an auxiliary pressure source AS to the rear wheel brake cylinders RR, RL, when the steep slope detector GD determines that the vehicle is on the steep hill, with the rear end of the vehicle located downward, and a braking operation sensor BD detects the depression of the brake pedal BP, with the rear end of the vehicle located downward, and when it is determined that the wheel speeds of front wheels FR, FL are zero and that the wheel speeds of the rear wheels RR, RL are not zero. And, the hydraulic braking pressure in the rear wheel brake cylinders Wrr, Wrl is decreased by a stop cancellation device RH in response to the operating conditions of the brake pedal BP, when the vehicle is moved after the wheel speeds of the rear wheels RR, RL became zero.
