DYNA4 Vehicle and Environment Simulation

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 in mutiple real-time on the PC or 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.
