DYNA4 Vehicle and Environment Simulation

Virtual Test Driving with Precise Vehicle Dynamics

DYNA4 Car Professional is the comprehensive vehicle dynamics simulation software for virtual test drives. The simulation environment can be used throughout all development phases: from conceptual function design on the desktop computer (MIL, SIL) to operating tests in real time with hardware-in-the-loop systems (HIL).

    Application examples of vehicle dynamics and drivetrain development

    • Design, testing, calibration and verification of vehicle control systems, e.g. ABS, ESP, 4WD control systems, active front steering, in SIL and HIL setups
    • Model-based rapid controller prototyping
    • Handling and ride comfort studies
    • Parameter studies and optimization of vehicle components, e.g. drivetrain concepts, steering system and axle suspension
    • Investigation of driving stability for passenger cars up to medium-sized commercial vehicles
    • Development and testing of mechanical components in virtual and physical test rigs
    • Pre-calibration of control devices on the hardware-in-the-loop simulator
    • Virtual test drives and animation in the driving simulator

    DYNA4 Concept

    The DYNA4 modular simulation environment consists of two main parts: an open demand-oriented Model Repository and a flexible, process-oriented tool environment (DYNA4 Framework).

    Model Repository in DYNA4 Car Professional

    • DYNA4 Car Professional contains detailed and proven models for vehicle dynamics
    • Tabled kinematic axles and MBS axles
    • Tire model TMeasy with simple parameterization, also other tire models as FTire, Pajeka etc. can be used Adaptation of the models and the framework to your needs
    • Virtual test rigs for tires and axles with process for automated parameterization
    • Driving on OpenDRIVE road network without conversion
    • Pre-configured examples, e.g. ISO maneuer for easy start in virtual test driving

    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
    • Rapid overview and automatic comparison of simulation results for different vehicle variants
    • Standard interfaces e.g. for ROS, ASAM, ADTF etc.
    • 3D Animation of your vehicle simulations with DYNAanimation
    • Software runs platform independent on PCs and on all common real-time platforms
