veDYNA: Real-Time Simulation of Vehicle Dynamics

The applications of veDYNA range from conceptual vehicle development at the PC and component tests in virtual or physical test rigs right through to function development and testing of vehicle dynamics controllers in software-in-the-loop and hardware-in-the-loop environments. Different product levels and numerous model enhancements provide an optimum solution for every user.

veDYNA supports the development of vehicle control systems from model-based design on the PC to tests in software-in-the-loop (SiL) and hardware-in-the-loop (HiL) environments.

veDYNA is successfully used in a wide range of applications:

  • Component development and testing, e.g. of axle suspensions, tires or steering systems, in virtual and physical test rigs
  • Function development and testing of vehicle control systems, such as torque vectoring, active chassis elements and distance controllers
  • Stability and comfort investigations, e.g. for the comparison of different axle concepts in passenger cars, trucks or racing cars
  • Conceptual studies and optimizations, such as computationally extensive variant calculations and parameter estimation
  • Virtual test drives in the driving simulator
  • Integration tests in laboratory vehicles
  • Function development and testing of driver assistance systems


veDYNA is available in three product levels which are tailored for different fields of applications.

 

All veDYNA product levels contain the same high-precision vehicle model, which is equally suited for the simulation of passenger cars, all-wheel-drive sports vehicles and Formula 1 racing cars. For the configuration of realistic driving maneuvers, a flexible road model and a powerful driver model are provided. Many standard maneuvers, such as the ISO lane change and braking on µ-split, as well as test courses of different complexity are already preconfigured and included in the installation.

 

The implementation and evaluation of the virtual driving tests is supported by preconfigured Matlab procedures, whose characteristic parameters may be changed via graphical user interfaces and which are easily adapted to your demands. Visualization of the results is possible during the run-time of the simulation with the animation tool DYNAanimation or at the end of the simulation by 2D plots via the comfortable veDYNA Plot GUI.

 

  • veDYNA Standard: veDYNA Standard is the specialized tool for vehicle dynamics analyses on PC platforms and in real-time operation. The open model architecture in a Matlab/Simulink environment offers full modularity to extend the delivered vehicle models with your own component models and adapt them flexibly to your specific application. All vehicle components, specifically the axles and tires, can be parameterized in detail. For in-depth investigations of the axle elasto-kinematics and its impact on vehicle performance and comfort, a library with real-time-capable multi-body axle models is provided.
  • veDYNA Light: veDYNA Light offers intuitive access to the vehicle dynamics simulation with Matlab/Simulink. Individual enhancements of the vehicle model and real-time applications are also possible. The model parameterization is supported by easy-to-use graphical user interfaces, which require only reduced data for axles and tires compared to veDYNA Standard.
  • veDYNA Entry: veDYNA Entry is a preconfigured, generic vehicle dynamics model for fast simulation on PC platforms – especially for educational use. The assignment of model data is supported by easy-to-use graphical user interfaces as in veDYNA Light. Simulink is not required.
