ABSTRACT:
The invention relates to a device for the centrallized control of the opening points of a motor vehicle, in which the opening points have electrical actuators, including two locking states, and comprising at least one electric motor, and some opening points have a mechanically controlled device with a lock key sending commands to a central control unit which also receives commands coming particularly from the ignition key and/or from a remote-control set and from an anti-attack button. The device according to the invention is characterized in that the central control unit is connected to each of the opening points by a single line (8) with three conductors (31, 32, 33) which will be used sometimes for power transfer and sometimes for information transfer, in that in each opening point the actuator is connected permanently between the three conductors of the said line (8), and in that the central control unit selectively applies to each of the said conductors (31, 32, 33) the voltages necessary for the execution of a sequence.
