Abstract
A system for controlling actuating members in the doors of motor vehicles has at least one electromotive actuating drive and at least one actuating element (switch, button) in the door of the motor vehicle, as well as a control unit located in the vehicle itself. The system employs only a two-wire connection between control unit and actuating drive. The control unit, in addition to an ordinary pole-reversing and evaluation circuit, furthermore contains a source of alternating voltage as well as means for connecting the alternating voltage and a decoder. At least two passive components (resistor, capacitor, coil) of different size are provided to be connected by the actuating element in parallel with the actuating drive into the two-wire connection.
