Abstract
A method of detecting blocking of a rotor of a motor driving an actuator member with movement in translation between a first abutment and a second abutment, the method comprising the steps of, during an angular movement of the rotor, estimating at least a position (X) of the actuator member relative to the two abutments, a travel direction of the actuator member relative to the two abutments, and also a travel speed (V) of the actuator member; and on the basis at least of the estimated position of the actuator member, of the estimated travel direction of the actuator member, and of the estimated travel speed of the actuator member, detecting blocking of the rotor.
