    Abstract: The system includes sensors (w) which provide signals indicative of the rate of rotation of at least one monitored wheel of the motor vehicle and electrically-controlled fluid actuators (4-9) for increasing and reducing the braking pressure applied to the braking elements of the vehicle. An electronic processing and control unit (30) connected to the sensors(W) and is arranged to pilot the actuators (4-9) in conditions of incipient locking of the wheels so as to bring about one or more cycles of anti-lock braking. In each of these cycles, the unit (10) causes in succession:
    a controlled reduction of the braking pressure when the at least one monitored wheel is in a condition of incipient locking,
    the holding of the pressure at a constant value until the acceleration of the monitored wheel exceeds a minimum positive threshold, and
    the increase of the braking pressure again. During the stage in which the braking pressure is increased again in each cycle after the first, the electronic unit (10) causes in particular:
    an initial pressure increase of an amount calculated on the basis of the total increase in the previous cycle and the durations of the last and penultimate periods of controlled reduction of the braking pressure, and
    a subsequent, slower increase in the braking pressure.
