VI-SportsCar

Integrated Simulation Environment

VI-SportsCar, the specialized simulation environment allows engineering teams to analyze a number of design alternatives of a virtual race car and its subsystems on a test rig or on a given race track. The vehicle is driven on a two or three dimensional track profile by a sophisticated driving program pushing it to its limit. A specialized and extremely fast quasi-static lap time prediction program is entirely linked to the model data base.

Product Benefits

  • Find a good initial setup before arriving at the test track;

  • Increase efficiency of your real world testing on the track and in the lab;

  • The system level approach helps to understand the vehicle performance by cross-correlating all individual components;

  • Open and extendable product architecture allows users to build models with entirely new designs;

  • Subsystem based architecture separates complex tasks and provides intuitive interface;

Simulation Examples

Validation is continuously performed in close collaboration with all our customers, and this helps improving the methods and the accuracy of the program prediction. One example is the validation of a GT car model running on the LeMans track.
