The new generation of drive-by-wire systems currently under development has demanding requirements on the electronic architecture. Functions such as brake-by-wire or steer-by-wire require continued operation even in the presence of component failures. The electronic architecture must therefore provide fault-tolerance and real-time response. This in turn requires the operating system and the communication layer to be predictable, dependable and composable. It is well known that these properties are best supported by a time-triggered approach. OSEKtime is a new working group within the OSEK/VDX initiative, which is presently defining a specification for a time-triggered operating system and a fault-tolerant communication layer. The operating system and the communication layer are based on applicable interfaces of the OSEK/VDX standard. This paper describes the basic concepts of these two service layers and the electronic architecture.
