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.

A method of detecting degradation of a real tire of a wheel includes the steps of: acquiring at least one first three-dimensional object representative of the shape of the real tire by using an electronic appliance including at least one three-dimensional sensor, the first three-dimensional object being made up of a set of capture points; determining the position of the center point of the real tire from the set of capture points; registering the first three-dimensional object to obtain a second three-dimensional object; transforming the second three-dimensional object in order to obtain one or more two-dimensional objects; and analyzing the two-dimensional object(s) in order to detect degradation of the real tire.
