The present invention addresses the problem of improving reliability in a plurality of service modes for a vehicle. A communication device according to the present invention is a communication device mounted on a vehicle, and is provided with: a detection unit that detects an output voltage value from a battery mounted on the vehicle; and a transmission unit that transmits a signal indicating a decrease in the output voltage value detected by the detection unit to an external device using power of a sub-battery mounted on the communication device when the decrease in the output voltage value detected by the detection unit satisfies a reference. The case where the reduction mode of the output voltage value satisfies a reference includes a case where an absolute value of a reduction amount of the output voltage value per unit time is greater than a reference value.

    本发明的课题在于提高关于车辆的多种服务方式中的可靠性。本发明所涉及的通信装置是搭载于车辆的通信装置,具备:检测部,其对来自搭载于所述车辆的电池的输出电压值进行检测;以及发送部,其在由所述检测部检测出的所述输出电压值的降低方式满足基准的情况下,将表示该情况的信号使用搭载于所述通信装置的副电池的电力发送给外部装置,所述输出电压值的降低方式满足了基准的情况包括每单位时间的所述输出电压值的降低量的绝对值大于基准值的情况。
