ABSTRACT:
The invention is directed to an arrangement for controlling a braking force applied to each of driven wheels and non-driven wheels depending upon a braking condition, with a hydraulic braking pressure supplied to each of wheel brake cylinders through an actuator. The actuator is controlled by the braking force controller into which output signals of wheel speed sensors are fed. The braking force controller is arranged to control the hydraulic braking pressure supplied to each of the wheel brake cylinders. When one driven wheel is under the anti-skid control, it is determined whether a difference speed between the driven wheels is greater than a predetermined value. If it is determined that the difference speed is greater than the predetermined value, the actuator is actuated to restrain the hydraulic braking pressure from being supplied to the wheel brake cylinder operatively connected to the other driven wheel, e.g., to hold the hydraulic braking pressure supplied to the wheel brake cylinder, or to reduce a rate of increase of the hydraulic braking pressure.
