The control unit 21 can provide the user with an alarm image or an alarm sound through the display unit 26 or the sound unit 27 upon receiving the ignition signal. In this case, in addition, the external server 30 can transmit accident information (accident information, vehicle information, driver information, and vehicle location information) to an agency or an insurance company control center capable of emergency rescue.

If the control unit 21 determines that the user has escaped from the vehicle after the vehicle accident by using the user acceleration value and the user attitude information, the second communication unit 24 receives the action point information from the server 30 can do.
