Embodiment Construction

[0094] figure 1 An exemplary form of data transmission processing according to a data transmission protocol is shown, in which a message is transmitted from a first communication unit to a second communication unit by a first data transmission mode "master transmission" and a message is transmitted by a second data transmission mode "slave "Device transfer" transfers the message from the second communication unit to the first communication unit. In this case, the messages each comprise a plurality of data packets DATA#n, whose senders may be different, ie master or slave.

[0095]First, the first communication device or master unit sends a synchronization packet FrameSync (FrameSync), which is used to synchronize the communication with the second communication unit or at least the first slave unit or other bus users and initiates the communication process. This is followed by an identification packet ID, which is used to identify a destination by a user identification SID (sl...

Abstract

An electronic communication system including at least first and a second communication units (master, slave) which are connected to one another by means of at least one first data line, wherein the communication system has a data transmission protocol which is designed such that at least one defined communication process comprises the transmission of a synchronization packet (frame sync) and / or of an identification packet (ID) and / or a command packet (CMD) and / or of an address packet (ADDR) from the first communication unit (master) to at least the second communication unit (slave) via at least the first data line.

Description

technical field [0001] The invention relates to an electronic communication system according to the preamble of claim 1 , a method for data transmission between at least one first communication unit and at least one second communication unit, and the use of the communication system in a motor vehicle. Background technique [0002] In the field of serial bus systems, for example, the prior art proposes data transmission protocols for which the flexibility is strictly limited when optimized for their application. Contents of the invention [0003] The object of the present invention is to propose a communication system and method for data transmission which allow a relatively flexible communication between at least one first communication unit and at least one second communication unit. [0004] The invention achieves this object by an electronic communication system according to claim 1 and a method according to claim 7 . [0005] Preferably, the data transmission protocol...
