SYSTEM FOR DETERMINING THE FORWARD SPEED OF AT LEAST ONE VEHICLE

Described is a system for determining the forward speed of at least one vehicle, comprising control means, each associated with at least one axle, and a communication means for transmitting signals or values between the control means. At measurement instants successive in time, each control means generates a corresponding sliding signal of the respective at least one axle. At a sharing instant, each control means transmits the respective sliding signal, and in the no-sliding condition, the value of a quantity related to the rotation of the respective axle or its own estimated forward speed of the vehicle to the other control means. When all the sliding signals indicate a sliding condition, one of said control means controls first braking means associated with one of the axles, so as to reduce a braking force applied to said axle.
