Summary
This report addresses the need for effective tools to train drivers in eco-driving techniques, which are designed to reduce fuel consumption and vehicle emissions. While eco-driving offers environmental, economic, and safety benefits, the authors note a lack of public understanding and a scarcity of reliable training tools. Existing commercial applications often rely on macroscopic fuel consumption models that lack calibration and validation. Consequently, the research aims to examine the eco-driving modeling capabilities of various traffic simulation tools and to develop a high-fidelity, driver-simulator-based modeling environment capable of reliably estimating fuel consumption and emissions while providing real-time feedback to drivers. The study employs a two-part methodology. First, it reviews existing sources of vehicle emissions data, including emission inventories and factors, and evaluates the modeling capabilities of microscopic, mesoscopic, and macroscopic simulation tools. The authors analyze how these tools represent vehicle kinetics and kinematics, specifically examining models such as VISSIM, CORSIM, and the Comprehensive Modal Emissions Model (CMEM). Second, the researchers develop a new hardware-in-the-loop modeling environment. This tool integrates the NADS MiniSim driving simulator with advanced engine modeling software (GT-Suite) via a validated SimLink interface. A simplified fuel efficiency model, based on a generic brake-specific fuel consumption (BSFC) map for an inline 4-cylinder engine, was developed. This model utilizes engine RPM and torque variables from the simulator to estimate power, engine efficiency, fuel consumption, and fuel economy. Additionally, an "EcoDash" interface was created using Windows Presentation Foundation to overlay real-time acceleration and efficiency data onto the simulator’s dashboard. The findings from the literature review highlight the strengths and limitations of current simulation tools. Microscopic models like VISSIM and CORSIM can calculate emissions based on instantaneous vehicle speeds and accelerations, though CORSIM’s emission data is noted as potentially outdated. CMEM provides a deterministic physical power-demand approach but requires external traffic data. The primary technical finding is the successful development and validation of the integrated driver-simulator tool. The system accurately simulates multiple driving environments and uses the BSFC model to provide immediate, quantitative feedback on driving behavior. The EcoDash successfully displays critical metrics, including speed, tachometer readings, and acceleration, allowing drivers to visualize the impact of their actions on fuel efficiency. The significance of this work lies in providing a validated, high-fidelity platform for eco-driving education and research. By integrating realistic driving simulation with accurate engine modeling, the tool addresses the gap in existing training resources that often rely on generalized or uncalibrated models. This environment allows for the precise evaluation of driver behavior and the reliable measurement of fuel consumption and emissions, supporting broader transportation initiatives aimed at sustainability and cost-effectiveness. The study concludes that such hardware-in-the-loop systems are essential for advancing eco-driving practices and improving the operational benefits of fuel-efficient driving techniques.
