Abstract

Régulation de la pression de freinage par mesure de la vitesse périphérique d'au moins deux roues d'un véhicule, le cas échéant par détermination de vitesses de référence correspondant aux vitesses périphériques en fonction de la vitesse du véhicule, puis formation à partir du maximum des vitesses de référence d'une vitesse de reférence d'ensemble pour les canaux de régulation affectés aux circuits de frein de roue. Le circuit délivrant la vitesse de référence, la vitesse de la roue motrice ou le signal de vitesse de l'essieu non moteur est déconnecté pendant la marche sans régulation, puis reconnecté lors de l'apparition d'un signal de régulation du glissement de la roue motrice et/ou après un temps prédétermine.Regulation of the braking pressure by measuring the peripheral speed of at least two wheels of a vehicle, where appropriate by determining reference speeds corresponding to the peripheral speeds as a function of the speed of the vehicle, then training from the maximum reference speeds of an overall reference speed for the regulation channels assigned to the wheel brake circuits. The circuit delivering the reference speed, the driving wheel speed or the non-driving axle speed signal is disconnected during unregulated running, then reconnected when a signal to regulate the slipping of the gear appears. drive wheel and / or after a predetermined time.
