It becomes possible to make a notification (call to a predetermined emergency call control center).

  Further, the information regarding the position information of the vehicle and the reference clock obtained by the first antenna element 11 and the first processing unit 31 is not limited to a device (information output device 120) that outputs position information such as a car navigation system. It may be in a form used to control another device 170 connected via.

  For example, based on the position information of the vehicle, it is detected that the driver is traveling uphill, and the number of rotations of the engine (the other device 170) is increased to prevent the speed from falling too much. Control to increase the number of revolutions of the engine (the other device 170) so as not to increase the speed too much, based on the time information based on the position information of the vehicle and the reference clock, sunrise time or sunset A mode is conceivable in which lighting control of headlights and small lights (other devices 170) is performed by calculating time.
