Abstract
When, after a yawing moment control starts in an anti-lock braking system the rear wheel on the low-.mu. road surface is locked and the speed of that wheel decreases below the threshold value VT1, the brake hydraulic pressure to the wheel on the low-.mu. road surface is decreased. At the same time, the brake hydraulic pressure to the rear wheel on the high-.mu. road surface is also decreased at reduced rate relative to the decrease on the low-.mu. wheel. As a result, a higher braking force acts on the wheel on the high-.mu. road surface than on the wheel on the low-.mu. road surface. When the speed of the wheel on the low-.mu. road surface decreases below the threshold value VT1 and when the speed of the wheel on the high-.mu. road surface decreases below the pressure-decrease restriction removal threshold value VT, the brake hydraulic pressure to the wheel on the high-.mu. road surface is decreased to be nearly equal to that to the wheel on the low-.mu. road surface to prevent the wheels on the high and .mu. road surfaces from being locked.
