This paper describes the interdisciplinary architecture selection study conducted by Embry-Riddle Aeronautical University (ERAU) to determine the Plug-in Hybrid Electric Vehicle (PHEV) architecture for its entry into EcoCAR2: Plugging In To The Future. This study includes a fuel, component, and architecture comparison to determine the most viable strategy to convert the competition vehicle, a 2013 Chevrolet Malibu, into a strong PHEV. Performance, energy, emissions, and consumer acceptability goals were established and summarized in the Vehicle Technical Specifications (VTS). Drive cycle simulations were used to create vehicle and component requirements for achieving the VTS targets. Three candidate architectures were then evaluated and compared for energy consumption, well to wheel (WTW) emissions, WTW petroleum energy usage, performance, packaging, and consumer acceptability.

With a growing need for a more efficient consumer based automotive platform, Embry-Riddle Aeronautical University (ERAU) chose to redesign the 2013 Chevrolet Malibu as a Plug-in Hybrid Electric Vehicle(PHEV). A Series architecture was chosen for its low energy consumption and high consumer acceptability when compared to the Series/Parallel-through-the-road and the Pre-Transmission designs. A fuel selection process was also completed and B20 Biodiesel was selected as the primary fuel due to lower GHG (Greenhouse Gases) emissions and Embry-Riddle's ability to produce biodiesel onsite using the cafeteria's discarded vegetable oil.

The RemoteLink effort supports the U.S. Army's objective for developing and fielding next generation hybrid-electric combat vehicles. It is a distributed soldier-in-the-loop and hardware-in-the-loop environment with a 6-DOF motion base for operator realism, a full-scale combat hybrid electric power system, and an operational context provided by OneSAF. The driver/gunner crewstations rest on one of two 6-DOF motion bases at the U.S. Army TARDEC Simulation Laboratory (TSL). The hybrid power system is located 2,450 miles away at the TARDEC Power and Energy System Integration Laboratory (P&E SIL). The primary technical challenge in the RemoteLink is to operate both laboratories together in real time, coupled over the Internet, to generate a realistic power system duty cycle. A topology has been chosen such that the laboratories have real hardware interacting with simulated components at both locations to guarantee local closed loop stability.

In this paper, a distributed driver-in-the-loop and hardware-in-the-loop simulator is described with a driver on a motion simulator at the U.S. Army TARDEC Ground Vehicle Simulation Laboratory (GVSL). Realistic power system response is achieved by linking the driver in the GVSL with a full-sized hybrid electric power system located 2,450 miles away at the TARDEC Power and Energy Systems Integration Laboratory (P&E SIL), which is developed and maintained by Science Applications International Corporation (SAIC). The goal is to close the loop between the GVSL and P&E SIL over the Internet to provide a realistic driving experience in addition to realistic power system results. In order to preserve a valid and safe hardware-in-the-loop experiment, the states of the GVSL must track the states of the P&E SIL.

The power system for the Future Combat System's (FCS) family of manned ground vehicles will not only need to satisfy mobility requirements, but also need to provide continuous and pulsed power for weapons, armaments and other auxiliary loads. Investigating hybrid power technologies has been an active research area for the U.S. Army RDECOM's Tank Automotive Research, Development and Engineering Center (TARDEC) Power and Energy System Integration Laboratory (P&E SIL). The P&E SIL is located in Santa Clara, CA and is maintained by Science Applications International Corporation (SAIC). Current P&E SIL efforts include imposing realistic loads on notional combat vehicle subsystems in order to evaluate components, such as motors and batteries.
