To suppress the missing of information acquisition at the reception side, when vehicle information is transmitted to the outside using a communication standard capable of long-range communication with low electric power.SOLUTION: A central GW 20A as an on-vehicle communication device includes: a speed acquisition unit 250 which is loaded on the vehicle to acquire a vehicle speed and which can communicate with the outside of the vehicle through a communication unit conforming to a communication standard enabling longer range communication than a short range radio communication standard with smaller power consumption than a mobile communication standard; a determination unit 254 which determines whether or not the communication unit can perform communication based on the acquired speed; and a communication control unit 256 which, when it is determined that communication by the communication unit is not possible, controls to store vehicle information with time information into a storage 204, whereas when it is determined that the communication is possible, controls the communication unit to transmit the vehicle information having the time information attached thereto stored in the storage 204, to an external device outside the vehicle.SELECTED DRAWING: Figure 3
【課題】低電力かつ長距離通信が可能な通信規格により車両の情報を外部に送信する場合において、受信側において情報の取得漏れを抑制する。【解決手段】車載通信装置としてのセントラルGW20Aは、車両に搭載され、かつ移動通信規格よりも電力消費量が低くかつ近距離無線通信規格よりも長距離の通信を可能とする通信規格の通信部を介して、車両の外部との通信を実行可能であって、前記車両の速度を取得する速度取得部250と、取得した前記速度に基づいて前記通信部の通信が可能か否かを判断する判断部254と、前記通信部の通信が不可能と判断された場合、ストレージ204に時刻情報と共に車両情報を記憶し、通信が可能と判断された場合、前記通信部がストレージ204に記憶されている前記時刻情報が付された前記車両情報を前記車両の外部の外部装置に送信するように制御する通信制御部256と、を備えている。【選択図】図3
