Domain Controlled Architecture - A New Approach for Large Scale Software Integrated Automotive Systems

Abstract

Electric and electronic functionalities increase exponentially in every mobility domain. The automotive industry is confronted with a rising system complexity and several restricting requirements and standards (like AUTOSAR), in particular to design embedded software for electronic control units. To stand against rampant functionalities software units could be restructured according to their affiliation and should not be attached to a certain place. This can be effected by integration on single controllers. On the one hand the system wide amount of hardware controllers could such be limited. On the other hand the workload for integration CPUs will rise. To support this paradigm, multi-core systems can provide enough processing power in an efficient way. This paper shows a first approach to combine automotive functionality on such a single controller.

Visualizing and analysing data-driven shift from decentralized to centralized automotive E/E architectures

“…It helps OEMs to distribute the development to several suppliers and makes integration and verification easy. On one side, it provides the flexibility to replace the failed ECUs in the EE system, and on the other, increases the cost because of the large number of ECUs and their wiring harnesses (Reinhardt & Kucera, 2013). The network communication used in decentralized EEA is insufficient for handling large amounts of data from sensors like cameras.…”

“…These domain controllers are processing large amounts of data and are connected to highspeed communication such as Flat Panel Display (FPD-Link) or Gigabit Multimedia Serial Link (GMSL) and networks like Ethernet. These architectures consequently lead to a reduction in the number of ECUs, as well as the length and weight of wiring harnesses (Reinhardt & Kucera, 2013;Jiang, 2019).…”
