Abstract
L’invention concerne un procédé de détection d’une panne d’un actionneur (4) de frein parking électrique, comprenant les étapes : mesure d’une valeur opérationnelle de l’actionneur ; pour au moins un paramètre de fonctionnement, calcul d’un intervalle de tolérance en fonction de la valeur opérationnelle mesurée ; pour chaque paramètre de fonctionnement, comparaison d’une valeur fonctionnelle dudit paramètre de fonctionnement à l’intervalle de tolérance ; et génération d’une alerte si ladite valeur fonctionnelle est en dehors dudit intervalle de tolérance. L’invention concerne en outre un dispositif de détection d’une panne d’un actionneur (4) de frein parking électrique et un véhicule comprenant un tel actionneur et tel dispositif de détection. Figure 1.The invention relates to a method for detecting a failure of an electric parking brake actuator (4), comprising the steps: measuring an operational value of the actuator; for at least one operating parameter, calculation of a tolerance interval based on the measured operational value; for each operating parameter, comparing a functional value of said operating parameter to the tolerance interval; and generating an alert if said functional value is outside said tolerance interval. The invention further relates to a device for detecting a failure of an electric parking brake actuator (4) and a vehicle comprising such an actuator and such detection device. Figure 1.
