TESIS DYNAware Cooperation with IAV

09/26/2009 // Next Generation of the Thermodynamic Engine Simulation Software

TESIS DYNAware Cooperation with IAVTESIS DYNAware and IAV Automotive Engineering present the second generation of the thermodynamic real-time simulation software DYNA4 Engine Themos. The new version integrates the core competences of both companies: comprehensive experience from numerous customer projects as well as simulation know-how acquired over many years. For the development of engine control units (ECUs), DYNA4 Engine Themos fulfills not only the stipulations of hardware-in-the-loop (HIL) applications but as well the challenging requirements of function development. This regards mainly to the accurate representation of the entire engine process, so the models can be used in the early stages of control unit function calibration. The robust and fast-simulating engine models are part of the process driven simulation environment DYNA4 and thus allow the continuous application of DYNA4 Engine Themos from function development to HIL tests in real-time.

“We know from our experience in numerous engine and control unit engineering projects that function developers do not only depend on the correct behavior of controlled systems but a high precision representation of reality becomes more and more important. In the new DYNA4 Engine Themos we emphasized great importance to this aspect” Kurt Blumenröder, President and CEO at IAV, explains. “Furthermore, the reliability and stability of the simulation environment is a key factor for the financial and time-saving benefits of the simulation,” adds Dr. Cornelius Chucholowski, General Manager at TESIS DYNAware.

The thermodynamical model from IAV and TESIS DYNAware has proven itself over the years for the testing of electronic control units for modern diesel and spark ignition engines. The entire simulation process of combustion engines thereby obeys the laws of thermodynamics. High accuracy is one important requirement for testing and development of modern ECUs, e. g. through simulation of the crank angle resolved cylinder pressure. In DYNA4 Engine Themos a physical model of the combustion process and gas dynamics allows for effects of variable valve lift and timing, multiple injections, exhaust gas recirculation and boost pressure control as well as exhaust gas aftertreatment. All engine model versions are integrated in a simulation environment with driveline and driver models, so that typical driving cycles can be simulated realistically and then analyzed. For any application it is of great importance that DYNA4 Engine Themos is based on fast and robust model algorithms and also delivers reliable results – an extraordinary challenge in regard to the amount of detail and complexity of thermodynamic simulation models.

DYNA4 Engine Themos is not only used for the development and testing of ECUs, it is also suitable for the selection and optimization of engine components with the aim to reduce fuel consumption – or in combination with additional model components – for the simulation of hybrid vehicles. All models are fully implemented in Matlab/Simulink. The open and modular architecture makes it easy to incorporate one’s own model components and allows adaption of the software to satisfy customer requirements.

TESIS DYNAware

TESIS DYNAware is the independent expert team for vehicle simulation in real-time. For more than 15 years the automotive industry has been employing TESIS DYNAware’s simulation models for controller and component development.

DYNA4, the virtual vehicle for test drives in the laboratory, contains high precision modules for simulation of vehicle dynamics (veDYNA), traffic environment (veDYNA Traffic), engine dynamics (enDYNA), and brake hydraulics (RT BrakeHydraulics). DYNA4 supports the entire development process of controller and components from model-based design to software-in-the-loop applications (SIL) on the PC to hardware-in-the-loop tests (HIL). Additional consulting and customization by experienced simulation teams ensure optimum results even for specialized simulation tasks.

TESIS DYNAware is headquartered in Munich and is part of the TESIS group of companies.
