Abstract

Anti-skid braking procedure for vehicle brake circuits, where the brake circuit comprises a source of pressurized fluid, and brake actuators mounted on the vehicle wheels, characterized in that it comprises the following phases: checking at least one it rolls by means of a sensor to detect its angular speed; feed the information from the sensor to an electronic control unit to generate an output signal resulting from a previously established condition that represents a risk of wheel lock verified, operate a valve assembly connected to the valve via the output signal. a set of brake actuators, the valve assembly of which comprises, first, a first valve that controls the flow of fluid between the source of the pressurized fluid and a set of brake actuators of which at least one actuator it is mounted on the verified wheel, and secondly, means to reduce the pressure in the same brake actuators, the set of brake actuators being mounted on the wheels belonging to a vehicle axle, cutting off the supply to the set of actuators when a signal representative of a first risk of skidding from a verified wheel appears, until the brakes are released, and the pr Actuator slippage is reduced in successive steps, resulting in each step change detecting a subsequent risk of wheel slippage verified.
