ABSTRACT:
Control apparatus is provided for an electromechanically operated closure panel such as used for sun roofs of automobiles and the like. The control apparatus includes a reversible electric motor drivingly connected to move the closure panel between a closed position and respective slidably retracted and pivoted open positions. In order to accommodate for the differences in relative movement between the electric motor and the closure panel during movement between the closed position and the tilted position, as compared to the movement between the closed position and the slidably retracted position, the invention provides a control mechanism for controlling the speed of the electric motor so as to reduce the same during tilting movement of the closure panel.
