Abstract
In anti-lock brake control of motor vehicles wherein the control of braking hydraulic pressure for braking the wheels is accomplished by repeating a control pattern in which during braking the braking hydraulic pressure is reduced and then increased in response to variations of a control speed selected from a wheel, detection means for detecting a lateral acceleration of the vehicle body is provided. When detection means detects lateral acceleration while the vehicle is braked, thereby detecting J-turn braking, a higher one of the wheel speeds of the left and right rear wheels is selected, and a lower one of the wheel speeds of the two wheels connected to one diagonally disposed hydraulic line to which the rear wheel whose speed is selected belongs is selected as a control speed to be applied to the one hydraulic line, while the wheel speed of the front wheel connected to the other hydraulic line is selected as a control speed to be applied to the other hydraulic line, whereby the wheel speed information of the floating inner rear wheel is neglected and the wheel speed information of the outer front wheel is taken as a control speed.
