DYNA4 Vehicle and Environment Simulation

DYNA4 Engine: Real-Time Simulation of Combustion Engines

The DYNA4 Engine Package provides physical models with realistic engine behavior, covering the whole range of engines powered by gasoline, diesel, and alternative fuels. Model your series-production engine, special high rev motorsports, heavy-duty or marine engine and use the model for

  • The conceptual design phase of engine development
  • Model-based controller design
  • ECU software and hardware tests in HIL systems
  • ECU pre-calibration

DYNA4 Engine 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

  • Analysis of design concepts for gasoline, diesel, and alternative fuels passenger car engines, high-speed race engines, heavy duty engines and marine engines
  • Design and control of supercharging, variable valve actuation, HCCI, and EGR
  • Test and development of controllers for exhaust aftertreatment
  • Hardware-in-the-loop tests for engine controllers with cylinder pressure sensing
  • Feasibility studies and evaluation of engine design

Simulation models in DYNA4 Engine

  • Thermodynamic models of the gas dynamics and the combustion process
  • Ready-to-use example models models for all common types of internal combustion engines and configurations
  • Pre-configured example models including example data
  • Preprocessing tool for the fast calculation of high-quality model parameters from standard data
  • Modular engine components repository
  • Ready-to-use scripts and tables for typical driving maneuvers, e.g. driving cycles.

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).

DYNA4 Model Repository

The DYNA4 Model Repository provides a clearly laid out user environment to administer and parameterize your own simulation models as well as the TESIS model library included

  • Assemble your virtual vehicles for test drives on the PC or HIL
  • Integrate your own simulation models seamlessly into DYNA4 and take advantage of all framework functions
  • The Model Repository is furnished with a base model library
  • You can easily add advanced DYNA4 simulation models (more information on DYNA4 Packages)

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
