Verfahren und Vorrichtung zur Erfassung eines Einklemmzustands bei einem Öffnungs/Schließelement

摘要

An entrapment detecting device for an opening/closing member includes a controller which memorizes a driving condition of a driving unit corresponding to load applied to the opening/closing member as a reference load data when a predetermined condition is satisfied during the movement of the opening/closing member for closing. The controller further calculates a driving data representing the driving condition during the movement of the opening/closing member for closing after memorizing the reference load data, and an abnormality detecting data generated by eliminating the load during the predetermined condition being satisfied from the driving data based upon the driving data and the reference load data, and the controller judges an entrapment based upon the abnormality detecting data.
