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.

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.
