Problems solved by technology

However, due to the lack of flexibility, such as accumulating travel data while the car is running and uploading it during charging, it is not possible to fully utilize a large amount of driving data, and it is also impossible to achieve a balance between communication cost reduction and processing information volume.

Abstract

A communications device for a vehicle, comprising: a vehicle travel data accumulation device (7) mounted in a vehicle (1) and which accumulates travel data for the vehicle (1); communications devices (8, 11) for mobile communications, that send some of the vehicle travel data accumulated in the vehicle travel data accumulation device (7) to an external server (10), and receive required information from the server (10) side; and communications devices (9, 12) for fixed communications, that send vehicle travel data accumulated in the vehicle travel data accumulation device (7) to the server (10), while the vehicle (1) is stopped. The communications devices (8, 11) for mobile communications send and receive the minimum required amount of information during vehicle (1) travel, and the communications devices (9, 12) for fixed communications send and receive a large amount of information while the vehicle (1) is stopped. This system configuration enables effective utilization of large amounts of travel data, as well as reduction of communications costs, and adequate processing information volumes.

Description

technical field [0001] The present invention relates to a vehicular communication device and a vehicular communication system that communicate necessary information between a vehicle and a data center, and particularly relates to a communication system that ensures an amount of information processing and communication costs by appropriately combining mobile communication and fixed communication Reduced vehicle communication devices and vehicle communication systems. Background technique [0002] As is well known, attempts are being made to distribute traffic information (including driving data of automobiles) detected by vehicles or road sensors at base stations such as information centers, edited / processed, and distributed as road traffic information. Furthermore, as such a system, for example, as described in Patent Document 1, a traffic information transmission system that alternately repeats the collection of traffic information and the transmission of the collected traf...
