Motor speed-based anti-pinch control apparatus and method with rough road condition detection and compensation

A powered panel control apparatus and method using an electric motor with a rotatable armature. The control generates time periods for a predetermined amount of angular rotation of the motor armature during one complete rotation. An average time period is computed over a predetermined number of time...

Zusammenfassung:	A powered panel control apparatus and method using an electric motor with a rotatable armature. The control generates time periods for a predetermined amount of angular rotation of the motor armature during one complete 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. A threshold for normal noise variations is adjusted upon detection of a rough road condition to compensate for the effect of rough road conditions on the powered panel control apparatus.
