Abstract: System for braking a vehicle comprising an anti-skid device receiving speed data from a detector coupled to a non-braked wheel, wherein the system comprises a correction device comprising on the one hand first apparatus adapted to tramsmit to the anti-skid device the speed data each time that the variations of these data in time are lower than a deceleration threshold representative of the aquaplaning of the non-braked wheel, and, on the other hand, second apparatus adapted, each time that the variations of the velocity data are greater than the threshold, to transmit to the anti-skid device an estimated decreasing speed datum. The invention is more particularly applied to the braking of aircraft.
