ABSTRACT:
An antiskid brake system for an automotive vehicle is provided which is designed to accumulate a wheel slippage parameter indicating a slippage condition of each wheel for given program cycles and regulate the brake pressure acting on each wheel based on the accumulated wheel slippage parameters. This improves the instability of antiskid brake control due to a small variation in tire-road adhesive .mu., irregularities of a road surface, turning of the vehicle, or a difference in diameter between tires. The antiskid brake system is alternatively designed to determine a slippage condition of one of wheels of a vehicle equipped with a rotation restraint mechanism such as an limited slip differential not only based on a slippage ratio of the one of the wheel, but also based on a slippage ratio of the other of the wheels. This permits a braking force acting on each of the wheels to be regulated precisely.
