To provide an emergency report system and on-vehicle device, capable of coping with accident having occurred at a place disabling communication.SOLUTION: The emergency report system includes an on-vehicle device 1 installed on a vehicle and a server 2 communicatable with the on-vehicle device. The on-vehicle device includes: a position identification section 111 for identifying a vehicle position where a vehicle is; an on-vehicle communication section communicatable with the server; an on-vehicle storage section 15 for storing an electric wave map showing a radio communicatable region; a non-communication identification section 112 for identifying a non-communicatable track which is a track where a vehicle runs and where radio communication is impossible; a stand-by time calculation section 113 for calculating stand-by time that is longer than time required for a vehicle to complete running on the non-communicatable track; a pre-call transmission section 115 for transmitting, to the server, a pre-call including stand-by time before the vehicle enters the non-communication track on the basis of a vehicle position; and a cancellation transmission section 116 for transmitting, to the server, a cancellation notification of cancelling a pre-call when a vehicle completes running on the non-communicatable track.SELECTED DRAWING: Figure 2
【課題】通信不能な場所での事故発生に対応できる緊急通報システム及び車載装置を提供する。【解決手段】緊急通報システムは、車両に搭載される車載装置1、および車載装置と通信可能なサーバ2を含む。車載装置は、車両の位置である車両位置を特定する位置特定部111と、サーバとの無線通信が可能な車載通信部と、無線通信が可能な地域を示す電波地図を格納する車載記憶部15と、車両が走行する走行路であって無線通信が不可能な走行路である無通信走行路を特定する無通信特定部112と、車両による無通信走行路の走行に要する時間よりも長い時間である待機時間を算出する待機時間算出部113と、車両位置に基づき、車両が無通信走行路に進入する前に、待機時間を含むプレコールをサーバへ送信するプレコール送信部115と、車両が無通信走行路を走破すると、プレコールを取り消す取り消し通知をサーバへ送信する取り消し送信部116とを備える。【選択図】図2
