Beschreibung
Zusammenfassung:	A method for preventing a vehicular door or window panel from pinching an obstruction extending through an aperture of the vehicle by measuring a capacitance of a field extending through the aperture using a capacitive sensor as a motor drives the panel between the open and closed positions, correlating the measured capacitance to panel position to create closing data, comparing the closing data to a reference map to create a compare value, and detecting an object in a path of the panel as it moves toward the closed position when the compare value exceeds a threshold value. The threshold value is dependent on the relative wetness of the sensor, which is determined by comparing the capacitance of the sensor at predetermined panel positions against a calibration wetness profile.
