Abstract
An anti-lock braking control method for a vehicle for preventing locking of vehicle wheels, wherein brake hydraulic pressure is controlled in accordance with a wheel speed to be controlled in each brake control system or channel. The increase in the brake hydraulic pressure in one of the brake control channels is started when a predetermined condition is determined to be met in that control channel and after the predetermined condition is also determined to by met in another control channel. The predetermined condition is determined to be met for a control channel when the system speed Vs for that control channel becomes higher than a speed Vv-.DELTA.Vo, which corresponds to the estimated vehicle speed Vv lowered by a predetermined minute value .DELTA.Vo.
