Méthode et système pour communiquer entre modules commandés à distance dans des véhicules

Verfahren und System zur Kommmunikation zwischen ferngesteuerten Modulen in Kraftfahrzeugen

Method and system for communication between remote-controlled modules in automotive vehicles

Abstract

A method and system for transferring pulse messages between remote-controlled modules (12) in an automotive vehicle includes a single wire bus (14) coupled to each of the modules (12) for transferring the pulse messages between each of the modules (12). A receiver circuit (20) associated with at least one of the modules (12) and coupled to the bus (14) provides a communication current to the bus (14). A transmitter circuit (16) associated with at least one of the modules (12) and also coupled to the bus (14) transmits the pulse messages utilising the communication current. The receiver circuit (20), thus, becomes active and accepts the pulse messages being transmitted by the transmitter circuit upon detecting the communication current being drawn from the receiver circuit.
