Abstract
The pressure increases of a hydraulic pressure control module for controlling the braking forces of wheels are decided on the basis of wheel speeds and a vehicle speed estimated from the maximum wheel speed. In this case, on condition that the incremental rate of the vehicle speed exceeds a predetermined threshold value, the vehicle speed exhibited before the incremental rate exceeds the threshold value is kept as an estimated vehicle speed, which is used for deciding the pressure increases. Thus, the pressure increases can be appropriately decided even in a situation where a motor vehicle passes through a very-low-.mu. road part or a drop in road level.
