VIRTUAL CAN NETWORKS OVER TTP--INTEGRATING LEGACY SYSTEMS WITHIN THE TIME-TRIGGERED ARCHITECTURE. IN: CAE METHODS FOR VEHICLE CRASHWORTHINESS AND OCCUPANT SAFETY, AND SAFETY-CRITICAL SYSTEMS

This paper describes how a time-triggered architecture, based on an underlying time-triggered communication protocol, can be employed to provide integration for a common backbone network to be used by all electronic vehicle control units. The concept of virtual networks over the time-triggered protocol (TTP) is first explained and discussed. The second part of the paper presents an implementation for a CAN emulation over TTP in some detail, and also outlines characteristics and concepts of this solution.
