On the occasion of EclipseCon 2020, Fraunhofer FOKUS launches its simulation environment Eclipse MOSAIC. This solution is based on VSimRTI (Vehicle-2-X Simulation Runtime Infrastructure), which has been developed over the last 15 years in close cooperation with the DCAITI of the TU Berlin and has already been used by more than 600 partners to test mobility services and traffic scenarios. Eclipse MOSAIC is now partially available as open-source.

Whether dynamic lane assignment or traffic light phase assistant, new mobility services are designed to increase safety, efficiency, comfort, and facilitate environmentally friendly transport. The Eclipse MOSAIC simulation environment allows to explore how this can be achieved, before the services are tested in field trials on the road. Eclipse MOSAIC can also be used for testing driver assistance systems and to optimize the entire traffic.

Flexible coupling of simulators

Eclipse MOSAIC integrates, depending on the simulation scenario, different aspects like individual building blocks into a holistic system, e.g., traffic congestion, battery charging of electric cars, or communication between other road users and a central cloud. The level of detail for individual aspects is variable: from a rough mobility scenario for an entire city to detailed individual driving maneuvers.

The open-source version of Eclipse MOSAIC already includes several simulators, e.g., Eclipse SUMO for traffic and OMNeT++ and ns-3 for communication. Further simulators can be coupled, e.g., Fraunhofer FOKUS offers the simulator PHABMACS for the realistic modeling of autonomous vehicles.

In addition to the simulator coupling, Eclipse MOSAIC manages the following tasks:

  • Federation: Individual simulators are interchangeable within a scenario.
  • Interaction: Information from one simulator is also taken into account by others.
  • Time: All simulators run synchronously.

Additionally, Eclipse MOSAIC offers several tools for evaluation and visualization of the results, which are also included in the open-source package.

In the recently completed EU project INFRAMIX, Eclipse MOSAIC was used to test scenarios for the future road that allow mixed traffic between conventional and automated vehicles.

Fraunhofer FOKUS has been a strategic development member of the Eclipse Foundation since May of this year and works in close cooperation with the partners of the working groups OpenMobility and openADx (Open Source for Autonomous Driving).

Testing Remote-Operated Driving virtually with Eclipse MOSAIC

Remote-Operated Driving is the bridge technology from human towards fully automated driving. In situations outside the driving domain of a highly-automated vehicle, e.g. if data is missing, or the autonomous function is unsure to make a certain decision, remote-operation is the key.

Evaluating Cooperative LiDAR Data Fusion for VRU Safety with MOSAIC Extended

People traveling by bike, on foot or e-scooters are little protected in the event of a collision and therefore known as Vulnerable Road Users (VRUs). Modern sensor systems for automated driving such as LiDAR are able to detect VRUs, thus facilitate warnings and safety. Yet, in certain situations, local blind spots could occur. Data fusion from different vehicles could solve this issue - as it is shown in a simulation study using PHABMACS and MOSAIC Extended.
