A cet effet, un système antipatinage (3, 7) électrique est agencé dans le circuit du courant de freinage (8), ledit système antipatinage étant raccordé, par une entrée de commande électrique (E2), à des sorties électriques (A1, A2) d'un régulateur antipatinage (1) habituellement utilisé pour des freins à actionnement pneumatique destinées à l'actionnement d'une soupape d'aération et d'évacuation de l'air. En outre, le système antipatinage présente une entrée de commande électrique (E5) supplémentaire pour la réception d'un signal électrique de freinage rapide (SB). Le système antipatinage (3, 7) est muni en outre d'une sortie de commande électrique (A3) pour un élément de commutation dans le circuit du courant de freinage (8). L'invention concerne également un système antipatinage pour un frein électrique et un procédé permettant de faire fonctionner un frein à commande électrique.
