Zusammenfassung:	A powered panel control apparatus and method is used with an electric motor having a rotatable armature. The control detects and generates time periods between the rotation of the armature over a predetermined constant amount of angular rotation. An average time period is computed over a predetermined number of time periods and compared with a threshold time period to determine if an obstacle is present in the path of movement of the panel. Transient counts are accumulated for increasing average time periods over a number of time period samples to detect an obstacle. Endzone ramp compensation adjusts a threshold for the initial entry of the panel into a seal.
