ABSTRACT:
The invention relates to a system for time multiplex transmission of analogue and digital information between components in a vehicle. The system includes a synchronizing unit (1) and a plurality of transmission units (2A, 2B, . . . , 2H) connected to a bus (B) with at least three bus conductors (BC1, BC2, BC3, BC4) for power supply and transmission of signals between the units. The synchronizing unit and transmission units may assume either an active state or a standby state. In its active state the synchronizing unit sends timing signals on a second of the bus conductors (BC2) for synchronizing the transmission units, and for definition of a plurality of time slots on a first of the bus conductors (BC1). In its active state, each of the transmission units can send and/or receive information selectively in at least one time slot on the first bus conductor (BC1). The synchronizing unit does not send any time controlling signals in its standby state. In its standby state a transmission unit lacks the ability of selectively receiving information from the first bus conductor or selectively sending information in a given time slot on the first bus conductor. Different criteria for changing between active state and a standby state apply to different transmission units.
