To improve reliability in various service forms for vehicles.SOLUTION: A communication device according to the present invention is a communication device mounted on a vehicle, which comprises: a detection unit which detects an output voltage value from a battery mounted on the vehicle; and a transmission unit which, when a reduction aspect of the output voltage value detected by the detection unit satisfies a reference, transmits a signal indicating the fact to an external device using power of a sub-battery mounted on the communication device. The case where the reduction aspect of the output voltage value satisfies the reference includes a case where an absolute value of the reduction amount of the output voltage value per unit time is larger than a reference value.SELECTED DRAWING: Figure 1

    【課題】車両についての多様なサービス形態における信頼性を向上させる。【解決手段】本発明に係る通信装置は、車両に搭載される通信装置であって、前記車両に搭載されるバッテリからの出力電圧値を検出する検出部と、前記検出部により検出された前記出力電圧値の低下態様が基準を満たした場合、そのことを示す信号を前記通信装置に搭載されるサブバッテリの電力を用いて外部装置に対して送信する送信部と、を備え、前記出力電圧値の低下態様が基準を満たした場合は、単位時間あたりの前記出力電圧値の低下量の絶対値が基準値より大きい場合を含む。【選択図】図1
