Abstract

A central locking system for a motor vehicle which has a number of actuators, each of which has a signal transmitter unit which sends data signals to a control unit as a function of current condition parameters of a monitored opening of the motor vehicle or as a function of externally input command signals, and the control unit generates control signals from these data signals, and final control elements of the central locking system, which bring about the locking and unlocking of the opening of the motor vehicle, are triggered by these control signals. According to the present invention, each actuator of the central locking system has a separate control unit to which the data signals of the signal transmitter unit of its actuator, as well as selected data signals of the signal transmitter units of the other actuators of the central locking system are sent.
