SYSTEM AND METHOD FOR CONTROLLING ANTI-PINCH POWERED WINDOWS

摘要

A system and method for an anti-pinch powered window system includes a window and a mechanical drive mechanism for raising and lowering the window. An electric motor drives the mechanical drive mechanism responsive to a command. A microcontroller unit generates the command responsive to a measured load current of the electric motor. A command to change direction of the window is generated responsive to a determination that the measured load current has exceeded a variable threshold level indicating that the window has stopped due to an obstruction. The variable threshold level is determined by the load current data stored within a memory.
