Session: Powertrain Adaptation for Connectivity and Automation
Title: Energy Savings Impact of Eco-Driving Control Based on Powertrain Characteristics in Connected and Automated Vehicles: On-Track Demonstrations
Location: Room 140A
Time: 11:00 – 11:30am
Code PFL150
Paper Number: 2024-01-2606
Argonne POC Jongryeol Jeong
Short Abstract - This research investigates the energy savings achieved through eco-driving controls in connected and automated vehicles (CAVs), with a specific focus on the influence of powertrain characteristics. Energy savings of up to 6% without connectivity and up to 22% with V2I connectivity are demonstrated with the conventional vehicle. A comparison is performed between the ICE vehicle and an EV to analyze the energy-saving impacts of eco-driving controls across different powertrain characteristics. This study emphasizes the significance of correlating powertrain design with controls and eco-driving strategies during the development of CAVs.
