Abstract
Method of operating an actuator (1) for maneuvering a movable element (52), comprising a motor of asynchronous type or of brushless type or comprising a motor associated with a differential brake, and comprising a partially irreversible reduction gear, which comprises a step of establishing a measurement of an operating parameter of the actuator and a step of using this measurement to determine whether the actuator is driving the movable element or whether the actuator is being driven by the movable element, and then a step of implementing first logic for determining an end of travel or an obstacle, or a step of implementing second logic for determining an end of travel or an obstacle, depending on whether the actuator drives the movable element or the actuator is driven by the movable element.
