Vehicle Simulator Improvement and Correlation Project for OSU FormulaSAE

Name: Robert Paasch
Knowledge Required: Knowledge of C# or basic programming fundamentals
Understanding of vehicle dynamics
Motivation: Driver in loop simulation allows setup optimization. This tool can also be used to guide some design decisions and provide driver training for new drivers.
Description: A tool has been developed using C# and the vJoy library which emulates a Logitech G27 USB steering wheel. The emulator is able to successfully replay a data file, logged from the real car’s MoTeC data acquisition system, through the simulation. This enables a comparison between the simulation and the real car to be made, because they can both have the exact same driver inputs. Simple experiments have already been conducted using the tool to perform iterations on the simulation models and improve their accuracy relative to the real car. The next step for this project will be to develop a systematic approach/tool to perform parameter sweeps, and perhaps some code to accomplish this by modifying the simulation parameters automatically. By sweeping a variety of parameters and comparing the results of each simulation model with the real car, the accuracy of the model can be improved further.
Objectives: Produce simulator that can do parameter sweeps to identify optimum vehicle setup
Improve on simulator lap timing capabilities
Deliverables: Review the work that has been done up to this point
Communicate with previous students who have been working on this topic
Implement drivers in the project phase and consider their feedback
Run detailed and in depth correlation analysis and improve the simulator software
Other comments: Formula SAE (Society of Automotive Engineers) is an international collegiate design series with over 10 worldwide competitions held each year. More than 550 universities around the world design, engineer, manufacture, test, and then compete with a formula-style race car, making it the largest student engineering competition in the world.
OSU has competed in FSAE since 1987, and in 2010 began an international collaboration with the German university Duale Hochschule Baden-Württemberg Ravensburg (DHBW), creating Global Formula Racing (GFR). Students at the two schools work together to design and build both a combustion and an electric car which share chassis, suspension, and aerodynamic designs but have different powertrains. The combustion car competes in the US each year and then joins its electric sibling to participate in European competitions.
Since 2010, GFR has won more competitions than any other team in the world, not only due to good engineering design, but great documentation, international communication, and project management. A senior capstone project with SAE offers a unique experience at OSU where students are offered great resources, design freedom, and accountability, and get to work with a large, international team, similar to how global engineering organizations operate today.
