DYNA4

DYNA4 is an open simulation environment for the virtual test driving of 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, which can be used in early development stages (MIL, SIL), or can be executed on Hardware-in-the-Loop systems (HIL) when ECUs are available. The 3D environment of DYNA4 simulation with road infrastructure and traffic provides virtual test fields for assisted and automated driving to ensure environmental sensibility.
