FUELabc Map

FUELabc Map addresses a fundamental challenge in vehicle operation: fuel efficiency is strongly influenced by driving behavior, particularly the relationship between vehicle speed, gear selection, and road conditions. While modern vehicles provide information such as speed, engine RPM, instantaneous mileage, and distance-to-empty, these indicators are largely based on recent driving history and do not proactively guide drivers toward optimal driving choices.

Conventional mileage displays calculate fuel efficiency over very short time intervals and present values only for the current driving speed. As a result, drivers must manually experiment by driving at multiple speeds to understand how mileage varies—an approach that is time-consuming, inconsistent, and often misleading due to the non-linear relationship between speed and fuel consumption. Similarly, distance-to-empty values fluctuate significantly when driving behavior changes, which can confuse drivers rather than help them make informed decisions.

FUELabc overcomes these limitations by providing expected fuel efficiency and distance-to-empty values at different constant speeds, even without requiring the driver to test each speed manually. By displaying mileage corresponding to various speeds, the system enables users to select the most fuel-efficient and optimal speed for their journey. In addition, FUELabc estimates fuel trip cost across alternate routes based on vehicle make and model, and informs users about fuel prices along the route, accounting for location-wise fuel price variations to support better route and cost planning.
