Claim:
A system for assisting fuel-efficient driving, comprising: a storage unit for storing a shift pattern map; a collection unit for collecting driving state information of a vehicle; a driving state calculation unit for calculating a current driving state and a target driving region based on the information from the collection unit and the shift pattern map, the target driving region including at least one of a fast upshift region, an upshift region, and a damper clutch ON region; and a display control unit for displaying the current driving state and the target driving region on a display in order for a driver to compare the current driving state and the target driving region based on at least acceleration or speed, wherein a red region in which a shift to a lower gear occurs because a current Throttle Position Sensor (TPS) value of the vehicle is higher than a current vehicle speed is displayed on the display in a color distinguishable from that of the target driving region.
