Todays premium class vehicles implement a variety of distributed applications cov- ering all areas of the vehicle, such as engine, chassis, body, comfort, as well as driver assistance functions. Most of these systems are interconnected via a com- mon network infrastructure, the so-called Electric and Electronic architecture (E/E- architecture) of the vehicle which includes not only the communication but also the power distribution, physical placement of components, and the mapping of function- ality on these components. This architecture includes different automotive commu- nication technologies and gateways to enable cross-network communication. Typical communication technologies to interconnect Electronic Control Units (ECUs) are Lo- cal Interconnect Network (LIN) [LIN10], Controller Area Network (CAN) [CAN91], FlexRay (FR) [Fle10], Media Oriented Systems Transport (MOST) [MOS10], and Low Voltage Differential Signaling (LVDS) [LVD95]. The general benefits of using a common E/E-architecture are among others the possibility of reusing sensor data for different applications, the optimization of the wiring harness (for example the avoidance of parallel cabling in the same installation spaces), the simple extensibility when adding new functions, and the support for having different expansion stages.
