Summary
This study investigates how different types of eco-driving support systems (EDSS) affect the proficiency of drivers' fuel-efficient driving skills. The authors distinguish between "direct" EDSS, which automatically intervenes in vehicle operation to improve fuel economy, and "indirect" EDSS, which provides feedback to encourage spontaneous driver effort. Motivated by the concern that direct systems may deprive drivers of the opportunity to master eco-driving techniques, the research evaluates these systems through the lens of "FUBEN-EKI" (Further Benefit of a Kind of Inconvenience), a design methodology suggesting that systems requiring active user effort can foster skill acquisition and subjective satisfaction. The researchers conducted a driving simulator experiment with 12 male participants divided into two groups. Group I used a direct EDSS featuring automatic fuel injection suppression, idle stop, and indicator lights. Group II used an indirect EDSS that displayed real-time fuel efficiency bars against customizable targets and allowed users to switch display modes. The experiment spanned three days, consisting of baseline driving, seven sessions with the respective EDSS, and a final post-intervention baseline session. Metrics included average fuel efficiency, coasting rate (indicating early accelerator release), accelerator smoothness, and subjective questionnaires regarding active effort and awareness. The results demonstrated that the indirect EDSS significantly improved driving proficiency, whereas the direct EDSS did not. In Group II, all participants improved their fuel efficiency in the final baseline session compared to the initial baseline, indicating skill retention. They also showed increased coasting rates and smoother accelerator operations, suggesting they had mastered specific eco-driving techniques. Subjectively, Group II participants reported higher levels of active effort and awareness of fuel efficiency. In contrast, Group I showed no statistically significant improvement in fuel efficiency or coasting rates between baseline sessions. While some individuals in Group I improved, others did not, and the group as a whole failed to demonstrate consistent skill acquisition. Accelerator operations in Group I tended to become more erratic during system use. The study concludes that indirect EDSS, by requiring drivers to actively interpret feedback and adjust their behavior, promotes the mastery of eco-driving skills and enhances motivation. This aligns with the FUBEN-EKI principle, where the "inconvenience" of manual effort leads to the "benefit" of skill proficiency and self-efficacy. Conversely, direct EDSS, while effective at improving fuel economy during use, fails to foster long-term skill development because it removes the need for driver intervention. The findings suggest that for systems aiming to educate drivers and create lasting behavioral change, indirect feedback mechanisms are superior to automatic control interventions.
