Abstract

Le procédé est mis en œuvre dans le contexte d’un moteur thermique ayant un bloc-moteur qui supporte mécaniquement le compresseur de climatisation (CP) et son embrayage (EE), ainsi qu’un capteur de vibration (CC) détectant des vibrations du bloc-moteur. Conformément à l’invention, le procédé comprend au moins un premier diagnostic d’enclenchement de l’embrayage et au moins un deuxième diagnostic d’enclenchement de l’embrayage effectués respectivement lorsque le moteur thermique est tournant et lorsque le moteur thermique est à l’arrêt, les premier et deuxième diagnostics d’enclenchement étant basés sur des détections d’impulsions vibratoires dans un signal de vibration (SV) délivré par le capteur de vibration qui sont représentatives d’un enclenchement de l’embrayage, et le deuxième diagnostic d’enclenchement étant effectué en confirmation d’un premier diagnostic d’enclenchement lors duquel aucun enclenchement de l’embrayage n’a été détecté.
