The Embry-Riddle Aeronautical University (ERAU) EcoEagles are participating in the EcoCar: The NeXt Challenge competition. The competition is a three-year collegiate event where 16 teams from North America compete to build a more efficient and better performing GM production vehicle. The three year collegiate competition is sponsored by the Department of Energy (DOE), General Motors (GM), and Argonne National Labs (ANL). The advanced vehicle technology competition has a history, and has been organized and ran for the past 20 years. The competition challenges collegiate minds to reduce the environmental impact of a Chevrolet EcoCAR by minimizing fuel consumption and reducing emissions while retaining the vehicle’s performance, safety, and consumer appeal. The main focus of the competition is to use real world vehicle development strategies and processes that would meet GM’s standard practices and safety protocols. All of the sponsors of the competition provide teams with engineering tools, equipment needed to create a realistic vehicle, and project design support to the teams throughout the competition. The ERAU team, the EcoEagles, has successfully devised a Plug-In Hybrid Electric Vehicle (PHEV) propulsion system that meets those requirements. The electrification of the powertrain and the use of biodiesel fuel are central themes in the EcoEagles’ strategy for improving fuel economy and tailpipe emissions. The team selected an electric range of approximately 25 miles based on the average commuter driving less than 33 miles per day [1]; meaning that most of the vehicle operation will be conducted using either fully electric or electric-assisted propulsion. The vehicle design consideration was accomplished by implementing a 1.3L GM Turbo Diesel coupled with a 2-Mode electrically variable transmission (EVT) and an A123 Lithium-Ion Iron-Phosphate 330V 12.8kWhr battery pack. The EcoEagles design will reduce petroleum energy consumption by 78%, improve fuel economy by 66%, and reduce well-to-wheel greenhouse gas (WTWGHG) emissions by 30%. The paper will focus on the 99% production readiness. The paper will also discuss and include vehicle test data supporting the energy efficiency, emissions, and performance / utility capabilities of the vehicle as determined by the first two years of vehicle development. The vehicle architecture and background information will also be presented to help the reader understand why the given architecture was chosen and how it might compare to the Chevrolet EcoCAR. Performance predictions made from simulations will be contrasted against those from the Hardware-in-the-Loop (HIL) development. Finally, on-road testing will also be compared with the same predictions with the goal of showing why the model-based, HIL enhanced, and vehicle technical specifications (VTS) did or did not agree.

Vehicle Development Process

The Hybrid Electric Vehicle Team of Virginia Tech (HEVT) is participating in the 2009–2011 EcoCAR: The NeXt Challenge Advanced Vehicle Technology Competition series organized by Argonne National Lab (ANL), and sponsored by General Motors Corporation (GM) and the U.S. Department of Energy (DOE). The goal of EcoCAR is for student engineers to take a GM-donated crossover SUV and re-engineer it to reduce greenhouse gas emissions and petroleum energy use, while maintaining performance, safety and consumer appeal. Following GM’s Vehicle Development Process (VDP), HEVT established team goals that meet or exceed the competition requirements for EcoCAR in the design of a plug-in range-extended hybrid electric vehicle. HEVT is split up into three subteams to complete the competition and meet the requirements of the vehicle development process. The Mechanical subteam is tasked with modifying and refining the Year 1 component specifications and designs for packaging in the vehicle. The Electrical subteam is tasked with implementing a safe high voltage system on the vehicle including the design and development of a Lithium Iron Phosphate (LiFePO4) energy storage subsystem (ESS) donated by A123 Systems. The Controls subteam is tasked with modeling the Vehicle Technical Specifications (VTS) so that the subteams can make intelligent design decisions. The Controls subteam also used a controller Hardware-In-the-Loop (HIL) simulation setup running a real-time vehicle model against the controller hardware to test the HEVT-designed Hybrid Vehicle Supervisory Controller (HVSC). The result of this design process is an Extended-Range Electric Vehicle (E-REV) that uses grid electric energy and E85 fuel for propulsion. The vehicle design is predicted to achieve an SAE J1711 utility factor-corrected fuel consumption of 2.9 l(ge)/100 km (82 mpgge) with an estimated all-electric range of 69 km (43 miles). Using corn-based E85 fuel in North America for the 2015 timeframe and an average North American electricity mix, the well-to-wheels petroleum energy use and greenhouse gas emissions are reduced by 90% and 30% respectively when compared to the stock vehicle: a 4-cylinder, gasoline-fueled Vue XE.

In this paper, the advantage of hybrid electric vehicle (HEV) equipped with dual clutch transmission (DCT) was presented. Five HEV simulation models equipped with DCT were built on the basis of AVL CRUISE software. According to different power-train configurations, different control strategies were built by MATLAB/SIMULINK. The advantage and disadvantage of each power-train configurations was analyzed through simulation. The results supplied the foundation for the next step vehicle development.
