Traffic models in Autosar
Hello,

I'm looking for some specifications in Autosar, to find some info on the traffic models. I mean some data of the type of traffic to be transmitted via Autosar communication stack (e.g. FlexRay Tp / CAN Tp / Lin Tp), that shall contain specification on the Period, data length, freshness constraints, and so on

I mean, what really goes on above the Autosar COM module, in the RTE, Application Layer. How the data comming from applications is structured and scheduled, what type of data could this be...

Thank You

P.S.: Oliver, I really hope to get your help, as usual :D

Hi Alexandru,

I hope you don't mind if someone else that Oliver is answering you! :)

The information you are looking for are located in the SystemTemplate (http://www.autosar.org/download/R4.0/AUTOSAR_TPS_SystemTempl...)

In chapter "5 - Communication", you will find all relevant information to describe you Communication Matrix in terms of structure (Frames, Pdus and Signals), and "behavior" (FrameTrigerring, PDUTrigering and SignalTriggering). Specialzed version are then derived for CAN/LIN and FlexRay specific protocol.
Once you have your communication matrix, whether you build it from scrtach or migrated a legacy one (which is often the case), you are able to map the data exchanged above the RTE (for all relevant inter-ECU communication) to the Signal that are available in your communication Matrix. This process is described in chapter "4.2 - Data Mapping".

I hope this will help you move forward.

Cheers,
Pascal
