To provide a vehicle emergency notification device and a vehicle emergency notification system for determining whether or not an emergency notification should be made to a vehicle that is in a communication impossible state with a simple system.SOLUTION: A vehicle emergency notification device includes: a vehicle information acquisition unit that communicates with a plurality of vehicles and acquires vehicle information including at least position information indicating a driving position of the vehicle at predetermined time intervals for each vehicle; a communication disruption vehicle detection unit that detects a communication disruption vehicle with which the communication is lost with the vehicle information acquisition unit; a communication state determination unit that determines that the communication disruption vehicle is a communication disabled vehicle when the communication with the communication disruption vehicle is not restored within the predetermined time interval; an other vehicle count unit that counts other vehicles that are different from the communication disabled vehicle and whose position information acquired by the vehicle information acquisition unit from the other vehicle is the same as the position information of the communication disabled vehicle immediately before the communication is interrupted; and an emergency notification determination unit that determines that an emergency notification is required for the communication disabled vehicle when the counted value by the other vehicle count unit is smaller than a predetermined value.SELECTED DRAWING: Figure 1
【課題】簡易なシステムで、通信不能状態となった車両に対する緊急通報の要否を判定する。【解決手段】複数の車両との間で通信を行い、少なくとも車両の走行位置を示す位置情報を含む車両情報を、車両毎に所定の時間間隔で取得する車両情報取得部と、車両情報取得部との間の通信が途絶した通信途絶車両を検出する通信途絶車両検出部と、通信途絶車両との通信が所定時間が経過するまでの間に復帰しない場合に、通信途絶車両は通信不能車両であると判定する通信状態判定部と、通信不能車両と異なる他の車両であって、他の車両から車両情報取得部が取得した位置情報が、通信不能車両の通信途絶直前の位置情報と同一である他の車両を計数する他車両計数部と、他車両計数部による計数値が所定値よりも小さい場合に、通信不能車両について緊急通報を要すると判定する緊急通報判定部と、を備えた車両緊急通報装置を提供する。【選択図】図1
