Description
Southwest Research Institute (SwRI) operates a fully autonomous electric vehicle known as the Shell Eco-Marathon Vehicle. This platform provides students with the opportunity to develop software, thus gaining hands-on experience in autonomous vehicle systems and advancing their careers. The vehicle competes against other fully autonomous vehicles, testing the performance and reliability of its software in real-world scenarios.
• However, improper handling during shipping damaged the previous speed encoder decoding method. A temporary fix was implemented, but it was limited — it provided accurate readings up to 3MPH but often falsely detected movement when the vehicle was stationary.
• Our project aims to develop a new, robust speed encoder decoding system capable of accurately measuring speeds up to 11.1m/s (24.9MPH). A test bench is needed for validation before installation. This system will be integrated with the vehicle’s state estimation system and securely mounted to ensure it does not interfere with any other vehicle operations.
