ABSTRACT:
Methods are provided for detecting and alleviating the pinching of an object in a window of a vehicle having a drive unit motor controlling a window based upon current signals received from a control switch, security system remote control, or security system controller. The detection method includes determining a current threshold for the motor, determining time required to close the window, monitoring drive unit motor current draw during a window close operation, and determining if the current threshold is reached before window close time has elapsed. The alleviation method includes determining a current threshold, determining window close time, monitoring drive unit motor current draw during a window close operation, determining if current threshold has been reached before window close time has elapsed, and positioning the window so the drive unit motor current is less than the current threshold. The methods can be programmed into a window control module.
