Abstract:
An in-vehicle emergency call apparatus takes in positioning data from a GPS receiver instead of from a navigation system. If the positioning data from the GPS receiver changes when the input of the ignition signal is off, the in-vehicle emergency call apparatus determines that the ignition signal breaks down, and failure of the ignition signal is reported to the user.
