Method for automatic calibration and associated actuation device and seat

A method for automatic calibration of an actuation device of at least one element to be actuated of a structure, the actuation device comprising a calculation unit and at least one actuator configured to actuate at least one corresponding element to be actuated, wherein the method comprises the steps of:

• controlling, by the calculation unit, a movement of each actuator to place each element to be actuated of the structure in a predetermined reference position;
• for each actuator:
• operating the movement of the actuator in a first direction;
• comparing a value of a characteristic variable associated with the actuator with a predetermined first reference value;
• if the value of the characteristic variable exceeds the first reference value, operating the movement of the actuator in a second direction opposite to the first direction;
• comparing the value of the characteristic variable associated with the actuator with a predetermined second reference value;
• if the value of the characteristic variable exceeds the second reference value, saving a position occupied by the actuator as the position of a first mechanical stop of the actuator.

An actuation device including a calculation unit configured to:

• control a movement of each actuator among at least one actuator, each actuator being configured to actuate at least one corresponding element to be actuated of a structure, to place each element to be actuated in a predetermined reference position;
• for each actuator:
• operate the movement of the actuator in a first direction;
• compare a value of a characteristic variable associated with the actuator with a predetermined first reference value;
• if the value of the characteristic variable exceeds the first reference value, operate the movement of the actuator in a second direction opposite to the first direction;
• compare the value of the characteristic variable associated with the actuator with a predetermined second reference value;
• if the value of the characteristic variable exceeds the second reference value, save a position occupied by the actuator as the position of a first mechanical stop of the actuator.
