Abstract
The invention relates to a method of diagnosing the state of wear of an actuator including at least one electric motor. The method comprises the following steps: recording a signal coming from the motor during activation and deactivation of the actuator, the signal including a first maximum during activation and a second maximum during deactivation; executing a windowing algorithm on the signal in order to obtain a standardized dataset including the first and second maximums; using at least one classification method for classifying into at least two classes in order to establish a score for the dataset in each of the classes of the classification method; and evaluating the state of wear of the actuator from the scores of the dataset.
