Abstract
This device comprising a control member (2) actuatable by a user so as to govern the powering of the actuator, is characterized in that it comprises means (10) for estimating the movements of the control member (2), along a travel thereof between extreme positions of control of the actuator, and means (12, 13, 14, 15, 16) for analysing these movements so as to derive therefrom a cue for controlling means (17) for powering the actuator so as to supply the latter with a quantity of current corresponding to the movement of the control member, as determined by these means of analysis on the basis of a predetermined correspondence law (15) stored in the latter means and of means (16) for aggregating the successive movements of the actuator during its various controls, and updated after each new control of the actuator by these means of analysis, so as to slave the position of the actuator to the position of the control member.
