To provide an accident notification device capable of utilizing a small-sized backup battery.SOLUTION: A power source is normally supplied to an in-vehicle communication IC 11 and an out-vehicle communication IC 12 of TCU4 from a vehicle battery 6. When a collision accident to a degree at which an airbag installed in a vehicle 2 expands occurs, and when a power supply from the vehicle battery 6 is cut off, the power source is supplied to the in-vehicle communication IC 11 and the out-vehicle communication IC 12 from BUB13. A short-range radio communication function is stopped when supplying power to the in-vehicle communication IC 11 and the out-vehicle communication IC 12 from BUB13.SELECTED DRAWING: Figure 1

    【課題】小型のバックアップバッテリを採用することができる、事故通報装置を提供する。【解決手段】平常時は、車両バッテリ6からTCU4の車内通信IC11および車外通信IC12に電源が供給される。車両2に搭載されているエアバッグが展開する程度の衝突事故が発生し、車両バッテリ6からの電力供給が途絶えた場合、BUB13から車内通信IC11および車外通信IC12に電源が供給される。BUB13から車内通信IC11および車外通信IC12への電源供給時には、近距離無線通信機能が停止される。【選択図】図1
