Abstract
This thesis focuses on the exploration of different schemes for the autonomous traversal of a connected corridor, and the vehicle development work done in Year 4 of the EcoCAR Mobility Challenge to enable the testing of one such scheme on Ponce De Leon Avenue in Atlanta, Georgia. Georgia Tech is one of 11 teams participating in the EcoCAR Mobility Challenge, a 4-year competition that is a part of the Advanced Vehicle Technology Competition (AVTC) series. In the fourth year of this competition, teams are challenged to refine an SAE Level II Autonomous feature (Adaptive Cruise Control), implement Vehicle-To-Everything (V2X) communication between the vehicle and connected intersections, and demonstrate a robust and reliable powertrain through extensive testing.
The effectiveness of three different schemes in autonomously traversing a Connected Corridor are explored using a cost function consisting of three costs: time taken to traverse the corridor, energy used, and driver comfort. Several key parameters will be varied to observe their impact on the three schemes’ effectiveness while a Simulink model and real-world testing will be used to validate the result of the schemes.
To perform real-world testing using the hybrid vehicle developed by the Georgia Tech EcoCAR team, a comprehensive vehicle development process was followed over the four years of this competition. The development and testing methodology of a supervisory controller for a hybrid vehicle is detailed in this thesis. Finally, the organization of vehicle testing activities in the final year of the EcoCAR Mobility Challenge will be described.
