Information transmission control device, server, and information transmission control system

An information transmission control device comprising:

• a transceiver to receive current lane segment information including specific information of a lane segment of a lane for a vehicle to travel along and a distance thereof from a head position of the lane segment;
• and
• a controller to control transmission of probe data by setting a second transmission start position, on the basis of a transmission interval distance showing a transmission interval represented in terms of travel distance for transmitting probe data from the vehicle to a server and on the basis of an offset corresponding to a distance for changing a first transmission start position being a position to start transmitting the probe data to the server, the transmission interval distance and the offset being set using the current lane segment information and history information about probe data transmission from the vehicle to the server,
• wherein the history information about a plurality of vehicles is stored in a storage of the server, and
• wherein the controller transmits the current lane segment information to the server, receives from the server the transmission interval distance and the offset which are set using the current lane segment information and the history information stored in the server, and sets the second transmission start position.

A server comprising:

• communication circuitry to transmit information to and receive information from a vehicle;
• a storage to store probe data transmitted from the vehicle in association with a lane segment at which the probe data is transmitted, and to store history information about probe data transmission;
• setting circuitry which uses current lane segment information including specific information of a lane segment of a lane for the vehicle to travel along and a distance thereof from a head position of the lane segment and uses history information about the vehicle's having transmitted probe data to the server, to set a transmission interval distance showing the probe-data's transmission interval represented in terms of travel distance and an offset corresponding to a distance for changing a first transmission start position being a position to start transmitting probe data to the server, and then transmit the transmission interval distance and the offset to the vehicle;
• and
• a controller to make the storage store, in association with the current lane segment information, the probe data transmitted from the vehicle at a second transmission start position set on the basis of the transmission interval distance and the offset.

An information transmission control system comprising:

• setting circuitry which uses the current lane segment information and the history, information, to set a transmission interval distance showing the probe data's transmission interval represented in terms of travel distance, and an offset corresponding to a distance for changing a first transmission start position being a position to start transmitting probe data to a server;
• and
• a controller to control transmission of the probe data to the server after setting a second transmission start, position using the set transmission interval distance and the set offset.
