Beschreibung
Zusammenfassung:	A control device for a linear actuator comprises a motor coupled to a device for converting a rotational movement into a translational movement configured to move a translationally mobile part. The actuator comprises at least one mechanical stop placed on a fixed part of the actuator, the group of at least one mechanical stop being configured to act as an obstacle to the relative helicoidal movement of a stud of the translationally mobile part when the stud reaches at least one predetermined position, contact of the stud with a stop generating a torque. The control device comprises a control module connected to at least one strain gauge configured to generate a signal indicative of the detected torque, the control module being configured to compare the amplitude of the signal generated by the group of at least one strain gauge against at least one predetermined value.
