Abstract

Ce dispositif comprend des moyens d'émission d'un signal de vitesse de roues, un commutateur de décélération en réponse à une variation de vitesse de roue supérieure à un seuil de décélération, un intégrateur engendrant un signal de profondeur de cycle, un moyen de commande de desserrage des freins pendant durée du signal de commande et pendant que le signal de profondeur de cycle est supérieure à une valeur de référence, l'intégrateur comprenant des moyens sensibles au signal de vitesse et engendrant un signal d'accélération de roue, des moyens émettant un signal de décélération maximale pendant le serrage du frein et des moyens d'intégration de la somme du signal d'accélération et du signal de référence de décélération pour former le signal de profondeur de cycle, le dispositif comprenant en outre des moyens sensibles à un nouveau serrage des freins et portant le signal de profondeur de cycle à une valeur qu'il aurait atteinte si le signal de référence était continuellement ajouté au signal d'accélération.This device comprises means for transmitting a wheel speed signal, a deceleration switch in response to a variation in wheel speed greater than a deceleration threshold, an integrator generating a cycle depth signal, a means of brake release control for the duration of the control signal and while the cycle depth signal is greater than a reference value, the integrator comprising means responsive to the speed signal and generating a wheel acceleration signal, means emitting a maximum deceleration signal while the brake is being applied and means for integrating the sum of the acceleration signal and the deceleration reference signal to form the cycle depth signal, the device further comprising sensitive means when the brakes are applied again and bringing the cycle depth signal to a value that it would have reached if the reference signal were continuously added to the acceleration signal.
