A workshop on the AMASS automotive case studies was successfully held at Assystem Germany on January 30, 2018, in Berlin. Fourteen participants attended, from 7 different partners (Assystem, Malarden University, Alten, Austrian Institute of Technology, Ansys Medini, Virtual Vehicle, and Tecnalia Research and Innovation).

Three case studies were addressed: "DC-Drive Workbench", "Advanced driver assistance function with electric vehicle sub-system", and "Collaborative automated fleet of vehicles". The second and the third case studies are known as case study 2 and 3, respectively, within AMASS. They will be demonstrated by means of a Model Car (or a platoon of Model Cars), which is a demonstrator for the research and development of autonomous driving vehicles (ADV).

  • DC-Drive Case Study: A pre-study for the Model Car drive system. The DC workbench is used as a simple version of the electric powertrain from the Model Car. This workbench will be used for Hardware in the Loop (HiL) tests to verify the model predictions with real-world observations.
  • Case Study 2: Advanced Driver Assistance Function with electric vehicle sub-system. The focus of this case study is on building blocks for ADAS with electric vehicle sub-system. The collaboration within AMASS will support the collection of field data and system requirements. One of the main goals of this case study is the reuse of safety artefacts and the use of pre-qualified components.
  • Case Study 3: This Case Study handles with a typical example of a collaborative safety-critical system: a platoon of several vehicles. A fleet of autonomous model cars in the scale 1:8 (at the state four of them are physically available) drives and communicates together at runtime via Car2Car communication (based on peer-to-peer WiFi) to form a system-of-systems (SoS) in a controllable environment. This case will also deal with the contract-based safety engineering approach, fault injection simulations, and the usage of monitors in order to automate the safety analysis.

Among others, the following research intentions for the DC-Drive-Workbench and the model cars were expressed by different partners: creation of formalised requirements and contract-refinement, automation of safety analyses (fault injection, model simulation), contract-based safety engineering, assurance case patterns, reuse of safety argument fragments and of monitors, combined safety & security analyses for cars in platoon, assurance cases and patterns, and the automated generation of monitors and verification by simulation (offline and/or during runtime).

The partners agreed to keep in touch and to organise their research efforts together for the themes mentioned above.
