Title:
経路探索装置
Document Type and Number:
Japanese Patent JP5475805
Kind Code:
B2
Abstract:
A route searching device according to an embodiment of the invention includes an estimated fuel consumption amount computing unit that computes an estimated fuel consumption amount of each interval constituting plural routes from a departure point to a destination and an optimum route selecting unit that selects a route in which a total of the estimated fuel consumption amount from the departure point to the destination is minimized. The estimated fuel consumption amount computing unit includes a unit for computing fuel consumption amount in cruise condition that computes fuel consumption amount in cruise condition for each interval by multiplying a distance of the interval and a fuel consumption rate determined according to an average vehicle speed a unit for computing fuel consumption amount in fluctuating vehicle speed that computes a fuel consumption amount in fluctuating vehicle speed for each interval in each road category by multiplying the distance of the interval and the a fuel consumption rate, the fuel consumption rate being determined from an average vehicle speed and the road category of the interval and a unit for computing fuel consumption amount in gradient road that computes a fuel consumption amount in gradient road for each interval by multiplying the distance of the interval and a fuel consumption rate determined according to a road average gradient. The estimated fuel consumption amount is obtained by adding the fuel consumption amount in cruise condition, the fuel consumption amount in gradient road, and the fuel consumption amount in fluctuating vehicle speed.
