Heterogeneous Multi-core ECU for Future eCars

Introduction and Goals

Modern high-end cars contain ~100 distributed Electronic Control Units (ECUs) and ~4 Km long cables to carry out complex functionalities with distinct requirements. Typically, these functionalities can be classified in any-time (infotainment), soft real-time (displays) and hard real-time (break). The functionalities embedded in the cars are expected to grow resulting in more number of integrated ECUs and cables. Such distributed Information and Communication Technology (ICT) infrastructure results in ever increasing weight, cost and complexity of modern automobiles. The project aims to build a centralized ICT infrastructure for future Electric Cars (eCars) to drastically reduce number of ECUs and cables.

The research interest within this context centers around novel concepts for hardware, software, and hardware/software co-design for future inner/inter-car ICT infrastructure, including but not limited to MPSOC-based ECUs, distributed control and battery management systems, formal verification, and model-based programming paradigm. Even though the scientific activities include a high degree of fundamental research, it involves regular contacts with renowned German automobile manufacturers as well as their partners in China.

Involved Projects

  • BMBF 16N11936: Innovative Electronic Control Units (ECU) für Elektrofahrzeuge
  • BMBF 16N11933: Car2X Integration in Automotive Electric/Electronic-Architectures

Objective

The project intends to build heterogeneous high performance multi-core ECU which is able to execute several mixed critical applications which are distributed in state-of-the-art architectures. In the process, performance enhancing Commercial Off The Shelf (COTS) components, for example multi-cores, GPUs, FPGAs, SDRAMs etc will be investigated. Safe integration of mixed critical applications adhering to ISO 26262 is intended.

Expected Outcome

  • High performance embedded computing ECU, maximizing FLOPS/Watt
  • Unified programming model to program heterogeneity
  • Mixed-criticality system design flow for ISO certification

Cutting Edge Technology

  • Components from high performance architectures, for example multi-cores, GPGPUs, DDR2/3 memories, FPGAs will be integrated to deliver high computation power together with reliable operation.
