Abstract

A process for detecting degradation of a switching device including an electromagnetic actuator configured to unlock a control mechanism including an elastic member. The process includes: (i) commanding the electromagnetic actuator, (ii) measuring an electrical current circulating in the electromagnetic actuator, (iii) determining from the measured electrical current a reaction time of the electromagnetic actuator, (iv) determining from the measured electrical current a quantity representative of the current circulating in the electromagnetic actuator, (v) determining a parameter in the form of a polynomial of the determined reaction time and of the determined quantity representative of the current circulating in the electromagnetic actuator, (vi) iterating the steps (i) to (v) for a set of successive commands of the electromagnetic actuator so as to obtain a set of values of the predetermined parameter, (vii) determining a degradation of the electromagnetic actuator from the evolution of the values of the set in the course of the successive commands of the electromagnetic actuator.
