Abstract
A method for operationally controlling a motor-driven device for driving a home automated closure or sun-shading apparatus includes at least the following steps: —measuring (E21), via a measuring device, a first value of the strength of an electrical current passing through an electric motor; —determining (E24) a difference in strength relative to the first measured strength value after a period of time starting from the moment that the first strength value is measured has elapsed; —selecting (E25) one of the first threshold strength values on the basis of the elapsed time period; —comparing (E26) the difference in strength determined relative to the selected threshold strength value; and —determining (E27) the presence or absence of an obstacle or end of travel on the basis of the result of the comparison step (E26).
