    Abstract: A window regulator system for a window coupled to a door and movable between fully open and closed positions and a short drop position and method of operation are disclosed. The system includes rails with window regulator lifter plate assemblies being moveable along the rails by cables. A motor winds the cables to move the window. An electronic control unit detects operation of at least one of a door handle and a latch of the door to identify a short drop request corresponding to the door shut or opened. The electronic control unit ensures that no freeplay exists in the window regulator system to provide accurate movement of the window and controls the motor to selectively raise the window to the fully closed position in response to the door being shut and temporarily lower the window to the short drop position in response to identifying the short drop request.

    Abstract: A power closure system for a vehicle and corresponding method of operation are provided. The system includes a door and a power actuator for moving the door between closed and open positions. The power actuator is adapted to output a holding force to hold the door at a hold position between the closed position and the open position. In addition, the power actuator is configured to output the holding force such that a force applied to the door by a user to overcome the holding force is substantially the same to move the door in either one of an opening direction and a closing direction.

    Abstract: A power closure member actuation system for a vehicle having a plurality of doors and corresponding method of operation are provided. The system includes at least one power actuator associated with and configured to move one of the plurality of doors. The system also includes an inclination sensor configured to detect an initial inclination of the one of the plurality of doors at a predetermined position of one of the plurality of doors and a current inclination of the one of the plurality of doors at a current position of one of the plurality of doors. The at least one power actuator is operated based on the current position of the one of the plurality of doors determined using the initial inclination detected at the predetermined position and the current inclination detected at the current position.

    Abstract: A control system for controlling a mechanically commutated direct current electric motor and corresponding method of operation are provided. The control system includes a motor current sensing circuit for sensing a motor current comprising a plurality of ripples due to commutation of the motor and outputting a motor current signal. The control system also includes a controller including a finite state machine unit and is configured to detect the plurality of ripples in the motor current and to determine whether each of the plurality of ripples is a valid ripple using the finite state machine unit. The controller is also configured to count the plurality of ripples determined to be valid using the finite state machine unit and to determine at least one of a motor rotational position and a motor speed of the motor based on a quantity of the plurality of ripples determined to be valid.
