Abstract: This work describes the development and the application of a computer-based vehicle simulator. Such real-time simulation software is currently used in our Department as a tool for optimizing the design of a racing car, namely a single-seat vehicle for the SAE-ATA formula. Being based on our custom multibody library Chrono::Engine, the vehicle simulator exploits a recent formulation founded on vector-measure differential inclusions and cone-complementarity problems (CCP)
