Effect of Driving Behavior and Vehicle Characteristics on Energy Consumption of Road Vehicles Running on Alternative Energy Sources

Abstract

Road vehicles using gasoline, a gasoline-electric hybrid, diesel, methane, hydrogen, and a hydrogen-electric hybrid were investigated for differences in energy consumption as a function of driving behavior and vehicle characteristics. The results show that driving behavior has a large impact on energy consumption of vehicles in real traffic. Forceful acceleration events were linked with increased energy consumption, while moderate acceleration and steady average speed were linked with energy consumption benefits. In vehicles with regenerative braking, the frequency of forceful braking events is linked with a statistically significant lesser energy consumption as energy is generated for the vehicle during those events. The tested hydrogen-and methane-powered vehicles were found to have the overall best results regarding energy consumption.

Driving Sustainably – The Influence of IoT-based Eco-Feedback on Driving Behavior

“…On the other side, deceleration, driving speed between 50 and 90 km/h, moderate engine speed at gears 2 and 3 as well as low engine speed at gears 4 and 5 decrease fuel consumption. These results are also consistent with the results of [16]. The driven distance, hard acceleration, and a higher average speed increase fuel consumption per kilometer driven.…”

“…The driven distance, hard acceleration, and a higher average speed increase fuel consumption per kilometer driven. Moreover, results show a higher fuel consumption for hard deceleration and if one considers the number of stops and the idle time during a trip separately [16].…”

“…Feedback must have an effect on one's driving behavior that leads to a decrease in fuel consumption [7,16]. However, little has been done to understand the effect of eco-feedback on driving behavior.…”

“…A reduction in GHG may be achieved rather quickly via changes in the behavior of drivers [2]. Among others, [7] and [16] outline that, in addition to car characteristics, ecodriving behaviorssuch as the maintenance of steady speedreduce fuel consumption. Thus, a change in driving behavior has the potential to decrease fuel consumption and GHG emissions to increase the sustainability of road travel.…”

“…Various research projects demonstrated a reduction of fuel consumption on average between 1% and 7% when providing ecofeedback to the driver [e.g., 3,6,25,27]. This means that eco-feedback must have an effect on driving behavior as driving behavior has a direct impact on fuel consumption [7,16]. Some studies already considered how separate driving variables change throughout the application of eco-feedback.…”
