In a method for the commissioning of a door or window closer which comprises an energy accumulator, a damping device with an electric motor being operable as a generator and a transmission element, the leaf is opened and/or closed at least once in a teach-in process, the angular position of the motor shaft is detected during opening and/or closing, a functional relationship is determined between the angular position of the motor shaft and an angular position of the rotatable leaf at least over an area of the opening width of the leaf and the functional connection is automatically taken as a basis for a subsequent actuation of the electric motor for the damping of the closing movement of the leaf.

A method for allocating operating parameters to at least two local control units intended to control a door movement for a motor vehicle, wherein: a plurality of parameter records of operating parameters is stored in each local control unit; a plurality of values of a detection criterion is stored in each local control unit, said detection criterion being based on at least two values of an electric variable; for at least one local control unit, a value of the detection criterion is prepared using the electric variable; in each local control unit the detection criterion is queried; and, a parameter record is selected in accordance with the value of the detection criterion determined during the query, and the corresponding operating parameters are allocated to the local control unit.

The invention relates to a health status assessment method for a transport vehicle automatic or semi-automatic access device comprising at least one leaf suitable for being actuated by a kinematic chain including at least one motor supplied with electricity and having an associated angular position and/or rotation speed encoder and at least one switch. Said method includes steps, for at least one actuating cycle of the kinematic chain between a first and a second position among the open and closed positions and a second position, consisting of: during one said cycle, acquiring information relative to the kinematic chain comprising at least one piece of information representative of the electrical energy consumed by the motor, and/or position and/or speed information provided by said encoder and/or binary information indicating positions of switches, dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value per functional segment, establishing a health status diagnosis comprising a degradation detection as a function of at least part of said calculated descriptor values.
