Title (EN) CONTROL SYSTEM FOR A SENSOR ASSEMBLY
(FR) SYSTÈME DE COMMANDE POUR UN ENSEMBLE CAPTEUR
Abstract:
(EN) In described examples of a control system for cleaning and monitoring a sensor assembly (200) disposed externally on a vehicle, the system includes a contaminant detection/identification subsystem that measures a resonant frequency of the sensor assembly (200) to detect contaminants disposed on an exposed surface (216) of the sensor assembly (200). A cleaning subsystem includes cleaning modes that expel the contaminants from the exposed surface (216) of the sensor assembly (200). A temperature monitoring device monitors a temperature of an actuator (210) disposed in the sensor assembly (200), and a fault detection device detects faults in the sensor assembly (200).
(FR) Dans les exemples de l'invention d'un système de commande pour nettoyer et surveiller un ensemble capteur (200) disposé à l'extérieur d'un véhicule, le système comprend un sous-système de détection/identification de contaminants qui mesure une fréquence de résonance de l'ensemble capteur (200) pour détecter des contaminants disposés sur une surface exposée (216) de l'ensemble capteur (200). Un sous-système de nettoyage comprend des modes de nettoyage qui expulsent les contaminants de la surface exposée (216) de l'ensemble capteur (200). Un dispositif de surveillance de température surveille la température d'un actionneur (210) disposé dans l'ensemble capteur (200), et un dispositif de détection de défaillance détecte les défaillances de l'ensemble capteur (200).
