First Claim
Patent Images
1. A system for assisting fuel-efficient driving, comprising:
- a collection unit for collecting driving state information of a vehicle;
a storage unit for storing a fuel consumption map over a variety of driving conditions, wherein the fuel consumption map classifies the driving conditions into several regions which represent various levels of fuel consumption efficiency; and
a calculation unit for calculating a current fuel consumption level and a target driving condition for achieving an optimal fuel consumption level of the vehicle, based on the information from the collection unit 10 and the fuel consumption map; and
a display control unit for graphically displaying the current fuel consumption level and the optimal fuel consumption level on a display such that a driver can compare the current fuel consumption level with the optimal fuel consumption level so as to pursue the target driving condition, wherein the several regions which represent various levels of fuel consumption efficiency are displayed on the display unit, each region variably increasing or decreasing width on a bar graph on the display depending on the current driving state of the vehicle.
