ABSTRACT:
An antilock brake control for motor vehicles, wherein the actual wheel speed of each wheel of the vehicle is detected, and in dependency on the detected wheel speed, a reference vehicle speed is computed from which a reference wheel speed lower than the vehicle speed is determined, and wherein when the actual wheel speed decreases below the reference wheel speed as a result of braking operation, the braking hydraulic pressure acting on the wheel is decreased to allow the actual wheel speed to increase, and then the braking hydraulic pressure is reincreased when the actual wheel speed has recovered sufficiently. When a J-turn state of the vehicle is detected by lateral acceleration, the reference vehicle speed is changed to a lower value and a second reference wheel speed is determined on the basis of that lower value. The control of the braking operation is thus carried out in dependency on the second reference wheel speed shifted to a lower level, whereby the time when the braking hydraulic pressure is increased is advanced, and the time length during which the braking hydraulic pressure is decreased is shortened so that effective braking operation is carried out in the J-turn state.
