Zusammenfassung:	A method for monitoring the quality of a communication channel supported by a sliding contact, the method comprising the following steps: controlling (401) the application of a continuous electrical signal onto one of the elements of the sliding contact, receiving (402) a plurality of values (V(n)) of electrical signals measured on the other of the elements of the sliding contact, estimating (408) from said plurality of measured values, a variance parameter value, comparing (409) the variance parameter value with a threshold (THR) and, on the basis of the result of the comparison, generating a signal (CHANNEL_OK, CHANNEL_NOK) representative of the quality of the communication channel. Un procédé de surveillance de la qualité d'un canal de communication supporté par un contact glissant, le procédé comprenant: commander (401) l'application d'un signal électrique continu à l'un des éléments du contact glissant, recevoir (402) une pluralité de valeurs (V(n)) de signaux électriques mesurées sur l'autre des éléments du contact glissant, estimer (408) à partir de ladite pluralité de valeurs mesurées une valeur de paramètre de variance, comparer (409) la valeur de paramètre de variance à un seuil (THR), et en fonction du résultat de la comparaison, générer un signal (CHANNEL_OK, CHANNEL_NOK) représentatif de la qualité du canal de communication.
