Abstract

A vehicle-mounted device (10) which receives and outputs a radio wave containing at least direction information as information includes: detection means which detects the radio wave; and control means which compares the detection direction received from the direction detection means which detects the direction of the vehicle head to the direction information so as to judge whether the information is to be outputted. Thus, it is possible to provide a vehicle-mounted device which can provide only the information required by a user, a method for outputting the information, and an information providing system.

Claims

1. A vehicle-mounted device which receives a radio wave including information, the information including at least direction information, comprising:

a detection unit configured to detect the radio wave; and

a control unit configured to decide whether or not the information is to be outputted, by comparing a direction detected by a direction detection unit configured to detect a direction in which a vehicle head of a vehicle is oriented, with the direction information,

wherein the control unit outputs emergency disaster information regardless of the direction detected by the direction detection unit when the information includes the emergency disaster information.

2. The vehicle-mounted device according to claim 1, comprising the direction detection unit.

3. The vehicle-mounted device according to claim 1, wherein the direction detection unit comprises terrestrial magnetism detection unit configured to detect terrestrial magnetism.

4. The vehicle-mounted device according to claim 1, wherein the information includes at least one of emergency disaster information, safe driving support information, long sentence reading out information, and local information.

5. The vehicle-mounted device according to claim 1, wherein if the information is the emergency disaster information, the control unit necessarily decides to output the information.

6. An information output method, comprising the steps of:

detecting a radio wave including information, the information including at least direction information; and

deciding whether or not the information is to be outputted, by comparing a direction detected in a detection unit configured to detect a direction in which a vehicle head of a vehicle is oriented, with the direction information detected in the detection step,

wherein in the deciding step the emergency disaster information is outputted regardless of the direction detected by the detection unit when when the information includes the emergency disaster information.

7. An information providing system, comprising:

a direction detection unit configured to detect a direction in which a vehicle head of a vehicle is oriented, and outputting the direction as a detected direction;

a roadside apparatus for transmitting a radio wave including information, the information at least direction information related to a traveling direction of a road;

a vehicle-mounted device which includes detection unit configured to detect the radio wave, and control unit configured to decide whether or not the information is to be outputted, by comparing the detected direction with the direction information; and

a server apparatus for transmitting the information via the roadside apparatus,

wherein the control unit outputs emergency disaster information regardless of the direction detected by the direction detection unit when the information includes the emergency disaster information.
