Title (EN) CRANKSHAFT, TRANSMISSION OR CAMSHAFT SENSOR, DIAGNOSIS SYSTEM AND METHOD IMPLEMENTING SUCH A SENSOR
(FR) CAPTEUR DE VILEBREQUIN, DE TRANSMISSION OU D'ARBRE À CAMES, SYSTÈME ET PROCÉDÉ DE DIAGNOSTIC METTANT EN ŒUVRE UN TEL CAPTEUR
Abstract:
(EN) The invention relates to a crankshaft, transmission or camshaft sensor (10) for a motor vehicle, intended for being connected to an engine control unit (30) by a cable (20). The sensor comprises a processing module (17) and a voltage-modifying circuit (18) configured to generate an output signal via an output port (12) of the sensor (10) allowing a diagnosis module (36) of the engine control unit (30) to detect and identify faults of the sensor (10) or the cable (20). In particular, the processing module (17) is configured to provide on its output port (172), when the toothed target (14) is immobile, a predetermined pattern representing the fact that the toothed target (14) is immobile, this predetermined pattern corresponding to a status change of the output port (172) of the processing module (17) with a predetermined time and repeated periodically. The invention likewise relates to a diagnosis system (1) comprising such a sensor (10), a cable (20) and an engine control unit (30). The invention also relates to a diagnosis method (50) implemented by said diagnosis system (1).
(FR) L'invention concerne un capteur (10) de vilebrequin, de transmission ou d'arbre à cames pour véhicule automobile, destiné à être relié à une unité (30) de contrôle moteur par un câble (20). Le capteur comporte un module (17) de traitement et un circuit modificateur de tension (18) configurés pour générer un signal de sortie sur un port (12) de sortie du capteur (10) permettant à un module 36 de diagnostic de l'unité (30) de contrôle moteur de détecter et d'identifier des défaillances du capteur (10) ou du câble (20). Notamment, le module (17) de traitement est configuré pour fournir sur son port (172) de sortie, lorsque la cible (14) dentée est immobile, un motif prédéterminé représentatif du fait que la cible (14) dentée est immobile, ce motif prédéterminé correspondant à un changement d'état du port (172) de sortie du module (17) de traitement d'une durée prédéterminée et répété périodiquement. L'invention concerne également un système (1) de diagnostic comportant un tel capteur (10), un câble (20) et une unité (30) de contrôle moteur. L'invention concerne aussi un procédé (50) de diagnostic mis en oeuvre par ledit système (1) de diagnostic.
