Electronic closing system for use as e.g. door closing system for access authorization of passenger car, has transmitting channels for operating transmitter, where operating signals are transmitted to channels with different frequencies

摘要

The system (3) has a device (4) formed as a controlling device, and another device (5) formed as an electronic key of an identification sensor. Transmitting channels operate a transmitter, and electromagnetic signals (7) transmitted between the transmitter and a receiver are coded operating signals for authenticating the latter device such that change of a condition of the former device is activated after positive evaluation of the operating signals. The operating signals with data are transmitted to the transmitting channels with different transmission frequencies.
