Abstract
A controller for a door system and an associated method of operation for actuating a door. The controller may be electrically coupled with a motor, an outer door switch and an inner door switch. The controller, activates a motor assist and may maintain a desirable current supply to the motor assist. Determining a relative position of the door and determining whether movement of the door is obstructed is performed. The controller actuates the door to an appropriate position and determines whether door operation exceeds a maximum time threshold. The controller may be configured to deactivate the motor assist once the door reaches an appropriate position or the door operation exceeds the maximum time threshold.
