DYNA4 - Function Development in Closed-Loop System Tests
DYNA4 is an open simulation environment for the virtual test driving of cars and commercial vehicles. The physical models include vehicle dynamics, powertrain, combustion engines, electric motors, sensors and traffic. Virtual test drives with DYNA4 facilitate safe and efficient function development and testing. Closed-loop simulations on the PC run faster than in real-time, e.g. for use in early development stages (MIL, SIL), or can be executed on Hardware-in-the-Loop systems (HIL) when ECUs are available. DYNA4’s 3D environment simulation with road infrastructure and traffic provides virtual test fields for assisted and automated driving wherever environment perception plays a key role.
Frontloading: testing and development of ECU functions in early stages
Safe testing in critical driving maneuvers, including near crash situations or vulnerable road users
Parameter variations for thousands of automated driving tests
Weather independence: reproducible environment conditions with rain, snow, fog, wind etc.
Direct comparison of configurations, variants etc.
Optimization of complex systems, e.g. operating strategies with many application parameters
Traceability of test runs through management and versioning of simulation input and output
