Abstract:
A control system for a sunroof assembly having a first pane, a second pane and a sunshade, the control system comprising:a first electric motor operable to move the first pane;a second electric motor operable to move the second pane;a third electric motor operable to move the sunshade;a central processing unit connected to the electric motors;a vehicle occupant accessible switch assembly having a first pane circuit, a second pane circuit, a pane venting circuit and a sunshade circuit;a first sensor operable to sense the position of the first pane; anda second sensor operable to sense the position of the second pane, each of the sensors being connected to the central processing unit and being operable to indicate at least one position of the pane to the central processing unit;the central processing unit operably causing the first electric motor to move the first pane to a tilted venting position if the switch assembly energizes the pane venting circuit;the central processing unit operably causing the panes to move independently from each other depending on the position of the switch assembly;the central processing unit operably causing the panes to move synchronously with each other depending on the position of the switch assembly;the central processing unit operably causing the third electric motor to move the sunshade if the switch assembly energizes the sunshade circuit;the central processing unit deenergizing the first electric motor if the first sensor indicates that the first pane is in a first predetermined position; andthe central processing unit deenergizing the second electric motor if the second sensor indicates that the second pane is in a second predetermined position.
