A Decentralized Time- and Energy-Optimal Control Framework for Connected Automated Vehicles: From Simulation to Field Test 2020-01-0579

The implementation of connected and automated vehicle (CAV) technologies enables a novel computational framework for real-time control aimed at optimizing energy consumption with associated benefits. In this paper, we implement an optimal control framework, developed previously, in an Audi A3 etron plug-in hybrid electric vehicle and demonstrate that we can improve the vehicle's efficiency and travel time in a corridor including an on-ramp merging, a speed reduction zone and a roundabout. Our exposition includes the development, integration, implementation and validation of the proposed framework in 1) simulation environment, 2) hardware-in-the-loop testing, 3) connectivity enabled virtual reality based bench-test, and 4) field test in Mcity. We show that, by adopting such inexpensive, yet effective process, we can efficiently integrate and test the controller framework, ensure proper connectivity and data transmission between different modules of the system, and reduce uncertainty. We evaluate the performance and effectiveness of the control framework and observe significant improvement in terms of energy and travel time compared to the baseline scenario.
