Abstract

Interface (4) entre un capteur (3) de vitesse de rotation d’une roue d’un véhicule routier et une première interface (11) d’un circuit (1) de freinage de service du véhicule et une seconde interface (21) d’un circuit (2) de freinage de stationnement du véhicule. Elle comporte un premier, respectivement second, commutateur (410, 420) entre une sortie d’alimentation (WSP1, WSP2) de la première, respectivement seconde, interface et une entrée d’alimentation (31) du capteur, et un troisième, respectivement quatrième, commutateur (430, 440) entre une sortie (32) du capteur et une entrée (WSS1, WSS2) de données de la première, respectivement seconde, interface. Les premier et deuxième commutateurs (410, 420) sont commandés en fonction d’un défaut d’alimentation de la première interface (11) et les troisième et quatrième commutateurs (430, 440) sont commandés en fonction d’un défaut de réception de données de la première interface (11).
