Abstract

La stratégie de serrage d’un frein électromécanique dépend d’une pression hydraulique déjà existante, afin d’ajuster la composante mécanique de la force de serrage et d’éviter un serrage excessif du frein. La composante hydraulique (Fhyd) d’effort de serrage est estimée d’après une mesure de la pression, soustraite d’une force cible (FTar) pour donner la composante mécanique à instaurer (FTarNew), et le moteur électrique de commande de serrage du frein est arrêté à une valeur de seuil (I2) du courant qui l’alimente, en fonction de la valeur de cette composante mécanique à instaurer. Figure pour l’abrégé : Figure 7.
