Control circuit and method for power operated windows, sliding roofs or door locks in motor vehicles

摘要

To operate a specific component, e.g. raise a window, this is normally initiated by a manual switch (T1) and an electronic switch (S1b) in series (logic AND operation). The electronic switch is initiated through a microprocessor (MCU). In the event of a failure to the microprocessor and its associated input circuits an emergency control circuit (IC2b) initiates the electronic switch
