Vector adds open source pre-configured Euro NCAP tests
Vector Informatik in Germany has added a series of pre-configured simulation tests for the Euro NCAP safety regulations to its DYN4 tool.
Release 9 of Vector DYNA4 includes preconfigured virtual test drive scenarios for braking and collision tests in Euro NCAP 2023, including automated evaluation.
The NCAP test manoeuvres are completely implemented in the ASAM standard OpenSCENARIO XML and can be executed directly in the DYNA4 simulator. Vector also makes them available free of charge as open-source downloads on Github.
The release also simplifies the use of ASAM OSI, making it easier to connect external sensors or ADAS driving functions.

Euro NCAP autonomous emergency braking (AEB) and forward collion warning (FCW) tests can only be carried out at great effort on a real test site. To prepare these tests, DYNA4 R9 offers automated, simulation-based test drives in accordance with the NCAP test protocol 2023.
These have been fully implemented using the ASAM standards OpenDRIVE and OpenSCENARIO XML 1.3 and includes both VRU (Vulnerable Road Users) collision scenarios with pedestrians and cyclists as well as C2C (Car-to-Car) collision scenarios with vehicles.
Vector makes this set of standard-compliant OpenSCENARIO XML files available free of charge on Github at https://vctr.it/ncap-github. DYNA4 also includes an automated KPI computation of the virtual test drive results with reporting based on the NCAP assessment schema. Thanks to the flexible function integration in DYNA4 as Simulink model, C-Code, FMU, AUTOSAR code and the real ECU, tests are supported throughout the entire development process.
In addition, DYNA4 R9 offers much easier use of the ASAM OSI standard, which defines standardized interfaces for communication between different models. The use of OSI makes it straightforward to integrate exported DYNA4 models in co-simulation environments, for example with external sensor models or automated driving functions.
The consistent implementation of OSI Sensor Model Packaging (OSMP) in DYNA4 R9 means when exporting DYNA4 models as functional mock ups (FMUs), externally routed OSI signals are automatically exposed in compliance with the standard.
OSI signals are also suitable for recording simulation results. DYNA4 embeds the binary OSI data in the ASAM MDF format and, with the current release R9, offers user-friendly options for analysis after the simulation. The content can be displayed graphically with just a few mouse clicks, while the new Python MDF wrapper allows programmatic evaluation of the OSI messages.
