Racetrack testing is time- and resource-demanding. Most teams apply it only in later stages where the real-world car is required. To ensure the real-world car can maneuver various racing situations, a scheme similar to the one of UPM Racing, allows for testing edge cases and simulation system failure systematically.
Just One Prototype
Like F1 and America's Cup teams, there aren't many prototypes or light vehicles available due to the enormous production and service costs. Formula Student teams also strive a season-long to appear reach-ready with their single racecar at an event and be competitive. It is just not worth it to employ your only prototype for tests that can be done in simulation.
Instrumentation and Test Automation
Digital twin simulation leveraging Speedgoat hardware, the ecosystem of Simulink and its toolboxes allows for establishing two lean testing workflows. You can design apps with App Designer to tune parameters and monitor signals from real-time applications. This allows even non-Simulink users to carry out testing tasks. Simulink Test™ provides tools for automating executing routine, simulation-based tests of models, generated code, and simulated or physical hardware.
