38

11. The mobile terminal device according to any one of claims 8 to 10, wherein the terminal control unit does not transmit the existence notification information indicating existence of the mobile terminal device when the terminal control unit judges based on the recognition information that at least another mobile terminal device existing in a vicinity of the mobile terminal device is recognized by the in-vehicle device.
12. The mobile terminal device according to any one of claims 8 to 11, wherein the terminal control unit performs judgment on whether at least another mobile terminal device existing in a vicinity of the mobile terminal device is recognized by the in-vehicle device or not based on the recognition information in regard to the another mobile terminal device satisfying a predetermined condition regarding traveling directions or traveling speeds of the mobile terminal device and the another mobile terminal device and the terminal control unit does not perform the judgment in regard to the another mobile terminal device not satisfying the condition.
13. A recognition support system comprising:
an in-vehicle device installed in a vehicle including a detection unit for detecting an object; and
a mobile terminal device to perform communication with the in-vehicle device, wherein
the in-vehicle device includes:
a vehicle exterior communication unit to perform wireless communication;
an in-vehicle detection unit to detect a vehicle present location of the vehicle;
a vehicle interior communication unit to acquire detection information on the object from the detection unit; and

39

vehicle position information indicating the vehicle present location and the detection information on the object and make the vehicle exterior communication unit deliver the recognition information, and
the mobile terminal device includes:
a terminal communication unit to perform wireless communication;
a terminal present location detection unit to detect a terminal present location of the mobile terminal device; and
a terminal control unit to judge whether the in-vehicle device recognizes existence of a first object equipped with the mobile terminal device or not based on the terminal present location and the recognition information received by the terminal communication unit and make the terminal communication unit transmit existence notification information to the in-vehicle device when the terminal control unit judges that the in-vehicle device does not recognize the existence of the first object.
