A control method for an actuator comprising: - a control module receiving a control electric signal and converting this control electric signal into a set-point value for an electric motor; - said electric motor driving a pump according to said set-point value received from said control module; - said pump generating a hydraulic power allowing to move a hydraulic jack; - said hydraulic jack comprising two chambers (9,10) adapted to be supplied by said pump and generating the effort of the actuator, said chambers (9,10) being separated by a piston connected to a stem; and - at least one pressure relief valve for limiting the effort generated by said actuator, said pressure relief valve being automatically opened so as to implement its limitation function when the difference of pressure between the two chambers (9,10) reaches a predetermined value, wherein, automatically, a monitoring is implemented, so as to be able to detect an opening of said pressure relief valve, and upon the detection of an opening of said pressure relief valve, automatically: - an auxiliary set-point value is calculated, allowing, when it is applied to the electric motor, to limit the speed of the latter to a predetermined maximum speed being defined so as to prevent an overheat of the actuator able to damage it; and - said auxiliary set-point value is applied to said electric motor instead of said set-point value, characterized in that automatically and repeatedly: - it is determined whether the control electric signal being received has the effect of generating an increasing difference of pressure or a decreasing difference of pressure in the hydraulic jack; and - if appropriate, the application of said auxiliary set-point value is inhibited, when said control electric signal being received has the effect of generating a decreasing difference of pressure in absolute value. - a control module receiving a control electric signal and converting this control electric signal into a set-point value for an electric motor; - said electric motor driving a pump according to said set-point value received from said control module; - said pump generating a hydraulic power allowing to move a hydraulic jack; - said hydraulic jack comprising two chambers (9,10) adapted to be supplied by said pump and generating the effort of the actuator, said chambers (9,10) being separated by a piston connected to a stem; and - at least one pressure relief valve for limiting the effort generated by said actuator, said pressure relief valve being automatically opened so as to implement its limitation function when the difference of pressure between the two chambers (9,10) reaches a predetermined value, - an auxiliary set-point value is calculated, allowing, when it is applied to the electric motor, to limit the speed of the latter to a predetermined maximum speed being defined so as to prevent an overheat of the actuator able to damage it; and - said auxiliary set-point value is applied to said electric motor instead of said set-point value, characterized in that automatically and repeatedly: - it is determined whether the control electric signal being received has the effect of generating an increasing difference of pressure or a decreasing difference of pressure in the hydraulic jack; and - if appropriate, the application of said auxiliary set-point value is inhibited, when said control electric signal being received has the effect of generating a decreasing difference of pressure in absolute value. - it is determined whether the control electric signal being received has the effect of generating an increasing difference of pressure or a decreasing difference of pressure in the hydraulic jack; and - if appropriate, the application of said auxiliary set-point value is inhibited, when said control electric signal being received has the effect of generating a decreasing difference of pressure in absolute value.
