Analysis of the Influence of Driving Style on Energy Consumption of a Hybrid Vehicle in High-Altitude Environments During Standardized Driving Cycles

This article analyzes the influence of driving maneuvers on a hybrid vehicle's energy consumption and emission rates. Employing data collected through OBD II and GPS technologies, route variables are meticulously documented following the EURO 6 standard, primarily for assessing pollutant levels within a Real Driving Emissions (RDE) cycle, facilitated by the use of a Portable Emissions Measurement System (PEMS). Throughout the study, we identify key variables that exhibit the strongest correlation with fuel consumption, including Longitudinal acceleration (Ax), Torque, Accelerator pedal open position (APS), and engine speed (RPM). These variables enable us to discern the Internal Combustion Engine's (ICE) operational conditions and devise a model that accurately estimates the rate of fuel consumption change concerning vehicle acceleration. Furthermore, we classify driving modes as ecological, RDE, or aggressive based on the State of Charge (SOC) of the vehicle. Our findings reveal that the type of driving conducted on the road and city altitude directly influence fuel consumption and emission factors (CO₂, CO, HC, and NO_x). Notably, we observe a remarkable 31.36% reduction in fuel consumption during ecological driving compared to aggressive driving.
