摘要

PROBLEM TO BE SOLVED: To provide an apparatus and a method for estimation the location of a travelling vehicle for accurately estimating the location of the travelling vehicle, without using a vehicle sensor. SOLUTION: The apparatus comprises a vehicle speed measuring means 1101 for measuring vehicle speed; a location measuring means 1101 for measuring the presence location of the vehicle; an output control means 1107 for integrating or compressing the vehicle speed and the presence location of the vehicle; a first communication means 1104 for transmitting/receiving information via a communication path 13; a map database 1201 for storing the location information; a second communication means 1203 for transmitting/receiving the information to/from the first communication means via the communication path 13; and a vehicle location correcting means 1204 for estimating and correcting the travelling location of the vehicle, based on the vehicle speed transmitted from the vehicle speed measuring means 1101 and on the location information from the map database 1201. Accordingly, the present location of the travelling vehicle can be estimated accurately. COPYRIGHT: (C)2004,JPO
