In an antilock brake control for motor vehicles wherein a condition of locking of the wheels during braking is detected from the wheel speeds, and a control pattern of decreasing and reincreasing of the braking hydraulic pressure is repeated for carrying out effective braking operation, at least a phenomenon occurring in the vehicle in J-turn state is detected, and when the phenomenon exceeds a predetermined value, the antilock brake control is shifted from the normal mode to a J-turn mode in which different conditions are used. To detect the J-turn state, the difference in wheel speed between the right and left wheels is detected. Alternatively, lateral acceleration of the vehicle is also detected. Another alternative is a combination of the steering angle, the coefficient of friction between the wheels and the road surface, and the vehicle speed.
In an antilock brake control method for motor vehicles, comprising the steps of:
