OSEK, an acronym for Offene Systeme und deren Schnittstellen für die Elektronik in Kraftfahrzeugen (eng., "Open Systems and their interfaces for the Electronics in Motor vehicles"), is a small, static operating system for microcontrollers, mainly used in automotiveengine control units. In computing, an operating system (OS) is the system software responsible for the direct control and management of hardware and basic system operations. ... A microcontroller is a computer-on-a-chip optimised to control devices. ... Car redirects here. ...

OSEKtime specifies a standard for time-triggered real-time operating systems.
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.
