From Automotive to Autonomous: Time-Triggered Operating Systems

Abstract

This paper presents an approach for application of time-triggered paradigm to the domain of autonomous systems. Autonomous systems are intensively used in areas, or situations, which could be dangerous to humans or which are remote and hardly accessible. In the case when an autonomous system is safety critical and should react to the environmental changes running within a very limited time frame, we deal with the same kind of problems as automotive and avionic systems: timing properties and their analysis become a crucial part of the system development. To analyse timing properties and to show the fault-tolerance of the communication, a predictable timing of the system is needed.

ATWin: An Improved and Detailed Startup Model of TTP/C

“…The time-triggered architecture (TTA) [1][2][3] is a general design framework for CPS that offers higher reliability, determinism, and maintainability compared to traditional event-triggered architecture [4]. It has been extensively adopted in various embedded real-time industry domains, particularly in aerospace and automotive electronics [5][6][7][8]. TTP/C (Time-Triggered Protocol Class C) [6,[9][10][11][12], which is based on TTA, has become the primary communication protocol for automotive networks that cater to the requirements of the next generation of real-time systems [4].…”

Notably, TTP/C is the first fully time-triggered communication protocol standardized by the Society of Automotive Engineers (SAE).…”
