Abstract

The Automotive OS is a software concept that all major carmakers currently pursue with the goal to align the software between all ECUs in the vehicle. However, concrete definitions of this concept are lacking, and each carmaker is following its own strategy. In this article we are providing a definition for the Automotive OS concept that focuses on the targeted abstraction level of the interfaces and the functional scope of this platform. We explain how the concept evolved from current vehicle software architectures and describe its relationship to modern E/E architectures like the zonal architecture, where the decoupling of the function from the underlying hardware is a key element. As this architecture contains central high-performance ECUs as well as traditional real-time ECUs located at the vehicle zones, we present which software is best suited for which purpose. Besides, we discuss how the Automotive OS approach affects the software lifecycle of its components and the interfaces and the challenges that still lie ahead.
