1. A method for informing fuel efficient driving comprising:
collecting, by a controller, vehicle context data that includes fuel consumption per second; calculating, by the controller, a fuel efficiency influencing factor that includes a driving time after starting an engine based on the vehicle context data; storing, by the controller, the fuel efficiency influencing factor in a database; analyzing, by the controller, a driving propensity based on the data stored in the database and producing fuel efficiency analysis data that includes a fuel efficient driving index; and displaying, by the controller, a fuel efficiency analysis result based on the fuel efficiency analysis data, wherein the fuel efficiency influencing factor further includes at least one of an idling time, a preheating time, a rapid acceleration time, a rapid deceleration time, and a driving distance after starting the engine, the driving time after starting the engine is divided into n pieces based on the fuel consumption per second, when the driving time after starting the engine is divided into a first time, a second time, and a third time based on the fuel consumption per second, the fuel efficiency analysis data further includes a first time ratio, a second time ratio, and a third time ratio, and the fuel efficient driving index is calculated based on the first time, the second time, the third time, the idling time, and indexation reference coefficients which are set differently based on the first time, the second time, and the third time. |
