Abstract (en)
The method involves controlling a power supply of actuator (2) by a diagnostic device (3) and a power supply of the coil by a control device. An electric characteristic of an electric signal supplying the actuator is monitored at level of the diagnostic device. Diagnostic of the actuator is deducted using the result of the monitoring step. Temporal analysis of variations of the electric characteristic of the signal is performed. Control units (32, 36) of power supply of the actuator are activated. A control unit of power supply of the coil is activated. Independent claims are also included for the following: (1) a diagnostic device of the power supply of a coil of an actuator (2) a computer program comprising computer program code unit to perform a method for diagnosing an actuator when the program is executed on a computer.
Abstract (fr)
Le procédé de diagnostic d'un actionneur (2 ; 2') comprenant une bobine (211, 212) et un dispositif (22 ; 22') de commande d'alimentation de la bobine, comprenant les étapes suivantes : - Commande d'une alimentation de l'actionneur grâce à un dispositif (3) de diagnostic, - Commande d'une alimentation de la bobine grâce au dispositif de commande, - Surveillance, au niveau du dispositif de diagnostic, d'une caractéristique électrique d'un signal électrique, notamment du signal électrique alimentant l'actionneur, et - Déduction d'un diagnostic de l'actionneur en utilisant un résultat de l'étape de surveillance. Le dispositif et l'actionneur mettent en oeuvre le procédé.
