First Claim
1. An operating control method of a motorized driving device of a closure or sun protection home automation installation, the closure or sun protection home automation installation including a concealing device including at least a screen, and a winding tube, the motorized driving device including at least an electromechanical actuator configured to enable winding and unwinding the screen on the winding tube, between a wound position and an unwound position, the electromechanical actuator including at least an electric motor, an output shaft connected to the winding tube of the concealing device, and an electronic control unit comprising at least a device for measuring an intensity value of an electric current passing through the electric motor, a memory storing a plurality of intensity threshold values, and a device for detecting obstacles and ends of travel during winding of the screen and during unwinding of the screen, said method comprising:
- a first measure step for measuring a first intensity value of the electric current passing through the electric motor via the measuring device;
a first determination step for determining a difference in intensity relative to the first measured intensity value, after a period of time has elapsed beginning from the moment at which the first intensity value is measured;
a selection step for selecting one of the intensity threshold values depending on the elapsed period of time, among a set of intensity threshold values stored in the memory;
a comparison step for comparing the determined difference in intensity to the selected intensity threshold value; and
a second determination step for determining the presence or absence of an obstacle or an end of travel by the detection device based on the result of the comparison step.

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).
