  Subproject 6: Automotive
The OSEKtime OS is a standard for a time-triggered operating system designed as a run-time environment for highly dependable real-time software in automotive electronic control units.
It consists of a real-time preemptive dispatcher and a fault-tolerant communication layer as described.
Proof that the execution semantics of AFTM and OSEKtime are equivalent.

Osektime: a Dependable Real-Time, Fault-Tolerant Operating System and Communication Layer as An Enabling Technology for By-Wire Applications
It is well known that these properties are best supported by a time-triggered approach.
A consortium consisting of German and French car manufacturers and suppliers, which aims at becoming a working group within the OSEK/VDX initiative, the OSEKtime consortium, is currently defining a specification for a time-triggered operating system and a fault-tolerant communication layer.

 TTTech - Time-Triggered Technology
TTP-OS provides time-triggered pre-emptive task scheduling and is compatible with OSEKtime.
Other application tasks can use a local timer, which is provided by TTP-OS and synchronized with the global time.
TTP-OS is based on the OSEKtime working group specifications for the OSEK/VDX operating system.

 TTA-Group - The Cross-Industry Consortium for Time-Triggered Systems
The contents of a slot (its size, position, and the packing of signals inside data frames) are defined by a separate middleware layer (OSEKtime FT-COM).
No, asynchronous access is possible using the non-blocking write protocol.
Typically, a separate middleware layer (OSEKtime FT-COM) performs the interfacing to the CNI, thus removing the need for the application software to do any direct CNI access.

  OSEKTime
The OSEKtime operating system serves as a basis for application programs which are independent of each other, and provides their environment on a processor.
The are two types of entities: interrupt services routines managed by the operating system and time triggered tasks.
The main concept is that the OSEKTime OS assigns its idle time to the OSEK OS.

 Open Source FlexRay Communication: Time Triggered OS and FlexRay Communication Middleware
As for OSEKtime, time triggered control is realized by OSEKtime itself and non time triggered control is realized by OSEK/VDX OS that should run during the idol time of OSEKtime.
Under OSEKtime environment, the existing application that run on OSEK OS must port from OSEK OS API to OSEKtime API in order to adapt limited environment on which non time triggered control can run only during idol time of time triggered one.
Under the OSEKtime environment non time triggered function, even if it is interrupt request, was interrupted by FlexRay communication function served by time triggered control.

 Synchronous: Distributed
We now have made available a tool-chain which can automatically generate distributed code for a multi-periodic Lustre program on a multi-processor architecture.
The processors are assumed to run the OSEKtime operating system, use non-preemptive scheduling, and communicate via the TTP protocol.
The activities of this project continue in the follow-up IST project Rise.

 Exploiting Mobile Agents for Structured Distributed Software-Implemented Fault Injection   (Site not responding. Last check: 2007-10-31)
In recent work, we have introduced the concept of using mobile agents for distributed SWIFI in time-driven real-time systems.
This paper presents a prototypical implementation of the agent platform for the OSEKtime real-time operating system and the FlexRay communication system.
It is further shown, how to implement fault injection experiments by means of mobile agents in a structured manner following a classification of faults in terms of domain, persistence, and perception.

 Control Static
OSEKtime - OSEK, an acronym for Offene Systeme und deren Schnittstellen für die Elektronik in Kraftfahrzeugen (German: "Open Systems and their interfaces for the Electronics in Motor vehicles"), is a small, static operating system for microcontrollers, mainly used in automotive engine control units.
Power electronics - Power electronics is the technology associated with the efficient conversion, control and conditioning of electric power by static means from its available input form into the desired electrical output form.
The role in DC/AC Electronics, Fifth Edition," is usually are described by combining the interaction of the other.

The study in this area is very important because software becoming more and more complex and the formalization of standarts (FlexRay, OSEKtime FTCom, OSEKtime), theoretical base for the integration of formal methods into development process as well some case studies on real-time system are needed.
Based on this formalization we develope an approach towards modeling and pervasively verifying industrial-strength systems, AutoFocus Task Model (AFTM).

The application runs on a system of several electronic control units (ECUs).
The local application programs of the ECUs run on top of a simple real time operating system kernel like described in the OSEKTime standard.
ECUs are connected via a FlexRay-like communication bus.
