About AVSandbox

We deliver exceptional tools at the cutting edge of vehicle simulation. With over 20 years of system simulation experience in the Motorsport sector, we know that no single challenge is the same. So, we apply adaptable, flexible, and solution-oriented approach, empowering our customers to achieve their technical and business objectives.

In 2009, we partnered with rFpro to provide integrations with our vehicle models for use in Driver-in-the-Loop simulators in motorsports. This partnership now covers the distribution of rFpro; Modelica libraries to interface vehicle models to rFrpo; and the development of sensor models to support the virtual testing of autonomous vehicles. We have been partners to Dassualt Systèmes for over a decade, offering the full suite of DYMOLA products alongside expert training and support.
