Abstract:
1. A method for preventing a closure panel for an aperture of a motor vehicle from pinching an object extending through the aperture when the closure panel is moved between an open position and a closed position, the method comprising: measuring a capacitance of a capacitive sensor proximate the aperture as the closure panel is moved between the open and closed positions; identifying a position of the closure panel using a position sensor as the closure panel is moved between the open and closed positions; correlating the measured capacitance to the position identified to create closing data for the position; comparing the closing data for the position to a reference map for the position to create a compare value; detecting the object in the aperture as the closure panel moves through the position toward the closed position when the compare value exceeds a threshold value dependent on a relative wetness of the capacitive sensor; and preventing the closure panel from continuing to move toward the closed position upon detection of the object.
