Abstract
The invention relates to a cyclical time-based communication system, for the transmission of useful data (DATA) between users of the system, which comprises a databus and users connected thereto. The data transmission occurs within cyclical repeating timeframes, each with at least two timeslots. Each timeslot is provided for the transmission of a message (Ni). A message (Ni) comprises at least part of the useful data (DATA) and each message (Ni) is provided with a code (ID). The bandwidth available for data transmission may be better utilized, if the code (ID) is placed within the message (Ni) as a part thereof, each message (Ni) is additionally provided with time information concerning the timeslot which may be extracted from the code and at least one of the timeslots within the timeframes may be used for transmission of various messages in various cycles. In a preferred embodiment the information relating to the current cycle comprises an ordinal number for the cycle. In the simplest case the number has two values 0 and 1. Even and odd cycles can thus be differentiated. The ordinal number may be increased to differentiate more cycles from each other. The transmission method is preferably based on the FlexRay protocol.
