Automobile fuel consumption estimation system, route search systems, and operation guidance system

摘要

PROBLEM TO BE SOLVED: To estimate the tendency of fuel consumption of each driver highly accurately in consideration of individuality of the driver or the state of an automobile or a road, whereas the fuel consumption is changed according to the operation state of each driver such as the degree of economical driving, and thereby sweeping prediction thereof is difficult.;SOLUTION: This fuel consumption estimation system has a fuel cost information processing operation part 903 for acquiring information necessary for determining fuel cost following a driving history from a vehicle, and determining a fuel cost tendency characteristic of a driver individual of the vehicle based on the information; a storage part 224 for storing the fuel cost tendency characteristic; economical driving degree setting parts 900, 903 for inputting the degree of economical driving aimed by the driver or setting it through an estimation means; and a predicted fuel consumption operation part 910 for predicting the fuel consumption along a traveling scheduled route from at least the set degree of economical driving and the fuel cost tendency characteristic of the driver individual. The fuel cost tendency characteristic may be managed in each pattern of the driving state including at least one of vehicle state information and state information of a traveling route.;COPYRIGHT: (C)2009,JPO&INPIT
