Abstract
An anti-pinch assembly is used for a closure panel movable between open and closed positions on a motor vehicle. A controller operably connected to the closure panel controls operation thereof. A position sensor connected to the controller indicates the position of the closure panel between the open and closed positions. A capacitive sensor mounted on the vehicle and connected to the controller provides an output signal to the controller indicative of the presence of a foreign object in the path of the closure panel. The controller varies the function of the capacitive sensor through a plurality of threshold levels as a function of the position of the closure panel as indicated by the position indicator. In a critical zone of travel with the closure panel nearing the closed position, the capacitive sensor can be utilized in either a contact mode or a non-contact mode or a combination of both.
