Patent ID: 7440840

Claim:
An ecological driving system in a vehicle, the ecological driving system comprising: state detecting means for detecting states including a first state and a second state of the vehicle; computing means for computing (i) first data on a fuel consumption in the first state and (ii) second data on a fuel consumption in the second state; and reporting means for reporting the first data and the second data, mutually distinctively, wherein the state detecting means uses a vehicle speed, an acceleration, and an opening of an accelerator as criteria to detect states including: an idling state, including the first state and the second state, where an engine of the vehicle idles; a void acceleration state where the accelerator is opened with the vehicle speed not increased; a sudden acceleration state where the vehicle accelerates suddenly: a normal driving state where the vehicle drives normally; and a constant-speed driving state where the vehicle drives at a constant speed: and wherein the computing means computes, with respect to a fuel consumption, data in the idling state, data in the void acceleration state, data in the sudden acceleration state, data in the normal driving state, and data in the constant- speed driving state, and the reporting means reports the five computed data, mutually distinctively.
