To provide a vehicular alarm system capable of realizing an alarm function even without a capability of detecting the movement of a user on the basis of the positional detection of a device having an electronic key function.SOLUTION: A vehicular alarm system includes a first device and a second device, both incorporated in a vehicle. The first device performs: authenticating the second device by first wireless communication processing with the second device; detecting an event where a state of the vehicle has changed in a given pattern in the case of succeeding in the authentication of the second device; and outputting a given alarm instruction when detecting an event of the first wireless communication processing being stopped. The second device performs: authenticating a portable terminal device by second wireless communication processing with the portable terminal device; executing the first wireless communication processing with the first device in the case of succeeding in authenticating the portable terminal device. Further, when detecting a given first state change in a state of the vehicle, the first device causes the second device to stop transmitting radio waves for the first wireless communication processing.SELECTED DRAWING: Figure 3

    【課題】電子キー機能を有する機器の位置検出に基づくユーザーの移動検出ができなくても警報機能を実現できる、車両用の警報システムを提供する。【解決手段】車両用の警報システムは、車両に搭載される第1の機器および第2の機器を備え、第1の機器は、第2の機器との間で第1の無線通信処理によって第2の機器の認証を行い、第2の機器の認証に成功している場合に、車両の状態が所定のパターンで変化したことを検出し、かつ、第1の無線通信処理が停止したことを検出すると、所定の警報指示を出力する。第2の機器は、携帯型端末装置との間で第2の無線通信処理によって携帯型端末装置を認証し、携帯型端末装置の認証に成功している場合に、第1の機器と第1の無線通信処理を実行し、第1の機器は、車両の状態の所定の第1の状態変化を検出すると、第2の機器に第1の無線通信処理のための電波の送信を停止させる。【選択図】図3
