Abstract
Obstacle detection for a moving element activated by a motor is disclosed. The obstacle detection may comprise a controller to: move the element at a substantially constant speed; determine an actual torque value to move the element at the constant speed; determine a torque parameter based on the actual torque value; comparing the torque parameter with a threshold value; and determining the presence of an obstacle if the torque parameter is above the torque parameter threshold; wherein the torque parameter is determined based on a set of historical torque values and the actual torque value.
