Abstract
The mobile element is a vehicle window pane, panel, movable seat or similar, conveniently guided, and driven by a DC electric motor with a permanent magnet, and the method comprises a step of detecting an entrapment or collision situation of the mobile element by means of a first fuzzy logic algorithm, which inputs are the mobile element's position and the increments that may occur in the intensity of the current demanded by said motor, which is evaluated from the relative increase of the current intensity at one turn of the motor and after one next, subsequent turn of the motor. A second fuzzy logic algorithm is used to control the mobile element's velocity, in close loop.
