Abstract
A method and device for detecting an object caught in the path of a vehicle power window system includes an acoustic sensor for sensing acoustic signals associated with the window as the window closes. A control circuit having control logic compares the sensed acoustic signals with a predetermined noise threshold. If a difference is determined between the sensed signals and the predetermined noise threshold, an object caught in the path of the vehicle power window system is assumed to be present and the control circuit controls the motor accordingly to either stop or reverse direction.
