Embodiment Construction

[0027] Next, an embodiment of the present invention will be described. figure 1 The structure of the communication system of this embodiment is shown schematically. This communication system includes: a data center 2 connected to a wide area network 1 such as the Internet, a user terminal device 4 (corresponding to an example of a communication device) that can be connected to the wide area network 1 via a router 3 in the house, and a vehicle 5 on the car navigation device 6 (corresponding to an example of a communication device). The vehicle navigation device 6 can be connected to a communication base station 7 connected to the data center 2 via a plurality of roadside information transmitting and receiving devices 8 (for example, road beacons) installed along the road.

[0028] In addition, there are multiple sets of the vehicle 5 and the vehicle navigation device 6 . That is, the communication system of the present embodiment includes a plurality of vehicles 5 and a plura...

Abstract

The invention discloses a communication system and a data center, and the technique makes the selection rule of algorithm reflect road practical situations in a greater deal under the condition of selecting one among a plurality of route search methods, thereby providing high reliability. The data center (2) records a plurality of records, the records are formed by departing-arriving travel experiences of vehicles respectively corresponding to a plurality of user IDs, the data center (2) receives zones and user IDs sent from a user terminal (4), extracts records provided with departing and arriving destinations in the zone from user travel lists corresponding to the user IDs, sets each abstracted record as an object, in all records of all the user travel lists, determines a record route (shortest route) of the departing and arriving destinations of recorded objects traveling successively at the highest speed, calculates search parameters of the route search algorithm realizing the shortest route, and makes one of the calculated search parameters as an optimal parameter.

Description

technical field [0001] The present invention relates to communication systems and data centers. Background technique [0002] Conventionally, there is known a navigation device that selects a route search algorithm suitable for the area where the host vehicle is located from among a plurality of route search algorithms (see Patent Document 1). [0003] Patent Document 1: JP-2008-76363A [0004] However, according to this technique, areas are classified into categories such as tourist areas, emerging residential areas, and cultural and educational areas, and which algorithm is suitable for each of these types is fixedly set in advance. Therefore, the actual state of the road when actually traveling in such an area cannot be reflected. Contents of the invention [0005] The present invention was made in view of the above problems, and an object of the present invention is to realize a selection rule of a highly reliable route search method that can better reflect the actua...
