ACTUATOR OPERATION DIAGNOSTICS METHOD

摘要

The invention proposes a method for diagnosing the operation of an actuator comprising an element designed to be moved between extreme positions, involving the steps wherein a position sensor acquires values of the position (P1) of the element of the actuator during a times period (T1) following transmission of a movement instruction aimed at positioning this element in one of said extreme positions, and of calculating the discrepancy (E1) between each acquired position value and a reference position value (PREF) associated with said extreme position. According to the invention, steps of determining the number (NINF) of discrepancy values that are below a threshold value and/or the number of discrepancy values that are above said threshold value and making the diagnosis regarding the operation of the actuator on the basis of said number.
