COMMUNICATION DEVICE, COMMUNICATION METHOD, Recording medium on which the communication program is recorded, AND VEHICLE

Abstract

The invention provides a communication device, a communication method, a recording medium on which the communication program is recorded, and a vehicle, which can quickly perform the upload of data from the vehicle to an information processing server while suppressing the increase in the data capacity for communication with a base station. A TCU includes: a wide-area communication section that performs wireless communication with a base station; a short-range communication section that performs wireless communication with an access point; a vehicle-to-vehicle communication section that performs wireless communication with a relay vehicle; and a communication control section that transmits upload data by using any one of the wide-area communication section, the short-range communication section, and the vehicle-to-vehicle communication section, wherein the communication control section transmits the upload data more preferentially by using the short-range communication section or the vehicle-to-vehicle communication section than by using the wide-area communication section when an upload deferment condition is met, and transmits the upload data more preferentially by using the wide-area communication section than by using the short-range communication section and the vehicle-to-vehicle communication section when the upload deferment condition is not met.

Description

technical field [0001] The present invention relates to a communication device, a communication method, a recording medium on which a program for communication is recorded, and a vehicle. Background technique [0002] Conventionally, a technique in which a device installed in a vehicle transmits data to a server is known. [0003] For example, Patent Document 1 discloses an in-vehicle terminal device having a cellular communication unit for communicating with a base station and a wireless LAN communication unit for communicating with an access point whose communication range is narrower than that of the base station. When the allowable time is long, the wireless LAN communication unit transmits data to the server, and when the data transmission allowable time is short, the cellular communication unit transmits data to the server. [0004] Also, for example, Patent Document 2 discloses an in-vehicle device that transmits data to a server via one or more devices provided in o...

AI Technical Summary

Problems solved by technology

[0007] However, as in Patent Document 1, in a configuration in which all data with a short transmission allowable time is transmitted via the base station, the data capacity for communication with the base station increases, and the cellular communication cost is higher than that of narrow-area communication such as wireless LAN. The cost of communication increases

In addition, as in Patent Document 2, when data is transmitted to the server via a device installed in another vehicle, when the number of devices in the vehicle to be passed increases, the data may not be transmitted to the server within the transmission allowable time.
