Patent ID: 7605554

Claim:
A method for detecting the pinching of an object in a window of a vehicle having a drive unit motor that opens and closes the window based upon current signals received from a window control switch, a security system remote control, or a security system controller, comprising the steps of: a) determining a current threshold for the drive unit motor; b) determining the time required to close the window by determining the position of the window and determining the time required to close the window based on the position of the window, wherein the position of the window is determined by designating a fully closed window position as a reference time value; determining the time required for the window to travel from the fully closed position to a fully open position; adding the time required for the window to travel from the fully closed position to a fully open position to the reference time value; determining the time required for the window to travel from a fully open position to a fully closed position; and subtracting the time required for the window to travel from the fully open position to the fully closed position from the reference time value, creating a resulting reference time value wherein the value of the resulting reference time value will determine the position of the window; c) monitoring the drive unit motor current draw during a window close operation; d) determining that the current threshold has been reached before the time required to close the window has elapsed.
