Abstract:
A method of electronically monitoring and controlling a process for adjusting movable parts, said movable parts including at least one of windows and sunroofs of a motor vehicle, to provide protection from pinching, said method comprising at least the following steps:a) supplying to a detection device at least one input variable and at least one output variable characteristic of the process for adjusting the movable parts; b) storing in the detection device a model describing the process for adjusting at least one of the movable parts in terms of process variables, wherein the model comprises a differential equation of the form mÂ·{umlaut over ({right arrow over (x)})}={right arrow over (F)}wherein m is mass; {umlaut over (x)} is acceleration of the at least one of the movable parts, and F is the sum of the forces acting thereon;c) optimizing the process variables of the model according to the at least one input variable and at least one output variable and storing values of the process variables in the detection device; d) continually evaluating current values of the process variables obtained by optimizing by means of a comparison of the current values with the values of the process variables stored in step c); e) calculating in the detection device a correcting quantity for the process for adjusting the at least one of the movable parts according to said comparison; and f) influencing said process for adjusting the at least one of the movable parts by feeding the correcting quantity into the process.
