Abstract:This research project aims to examine the eco-driving modeling capabilities of different traffic modeling tools available and to develop a driver-simulator-based eco-driving modeling tool to evaluate driver behavior and to reliably estimate or measure fuel consumption and emissions. The proposed driver-simulator eco-driving modeling tool consists of a driving simulator integrated with an advanced engine modeling software in a hardware-in-the-loop modeling environment. The high-fidelity driving simulator has the advantages of being able to accurately simulate multiple driving environments and provide real-time feedback to the driver. A simplified fuel efficiency model based on a generic brake-specific fuel consumption (BSFC) map for an inline 4-cylinder has been developed and tested. By using the engine RPM and engine torque variables provided by the NADS MiniSim with the generic BSFC model, power and approximate engine efficiency, fuel consumption, and fuel economy are estimated within the MIniSim simulation environment. Using Windows Presentation Foundation (WPF) an EcoDash is created. The developed EcoDash overlays on top of the existing MiniSim Dashboard that include a speedometer, a tachometer, and in the center of the speedometer cluster is an acceleration display.
