DYNA4 Vehicle and Environment for Virtual Test Driving
Open Simulation Environment for Virtual Test Driving of Cars and Commercial Vehicles
DYNA4 vehicle and environment simulation runs many times faster than real-time on the PC or can be run on Hardware-in-the-Loop systems (HiL). The simulation models for vehicle dynamics, powertrain, combustion engines and traffic are used for function development and ECU tests in virtual driving tests.
DYNA4 is driven by industry standards and connects to your tool chain via flexible interfaces. The Simulink-based modeling with DYNA4 guarantees the re-use of your components or Funcitonal Mockup Units (FMUs) and thus allows efficient Rapid Prototyping. The 3D animated world with road infrastructure and traffic provides a realistic environment for virtual testing of your ADAS sensors, as cameras, lidar, radar and ultrasonic.

- You can easily add advanced DYNA4 simulation models (more information on DYNA4 Packages)
DYNA4 Framework

- Clear management of models, data, simulation scenarios and results
- Transparency, traceability and reproducibility of simulation projects
- Open model structure in Matlab/Simulink
- Seamless integration of your simulation models in the DYNA4 GUI
- Integrated test automation and parameter variation
- Adaptations to your workflows with configuration of views, Eclipse plugins, HTML user interfaces
