Abstract

The present invention features a method of calculating a path that minimizes fuel consumption and costs thereof. In preferred embodiments, the method includes forming a driving speed profile by predicting a change in driving speed and forming a path that minimizes fuel consumption and costs thereof by applying a fuel consumption cost modeling method using the driving speed profile and traffic information or the like.

Description

technical field [0001] The present invention generally relates to a method of calculating a route of a vehicle. More particularly, the invention relates to a method of calculating a vehicle route that minimizes fuel consumption and its costs. Background technique [0002] Generally, existing navigation devices store map data internally, calculate the shortest distance between a starting point and a destination, and issue instructions leading to the destination. [0003] However, this method of finding a route does not take into account information about current traffic conditions, so that even if the distance shown on the map is short, it may take longer than other routes depending on traffic conditions. [0004] In such a navigation device, a vehicle navigation guidance system calculates a route to guide the vehicle to a driver's intended destination, and provides driving instructions to the driver in consideration of the vehicle's current position and driving direction, s...
