Title: COMMUNICATION SYSTEM, VEHICLE-MOUNTED APPARATUS, AND RECORDING MEDIUM RECORDING PROGRAM
Abstract: A vehicle-mounted apparatus that is capable of wireless connection with a roadside device is provided. The roadside device is on, above, or below a road. The vehicle-mounted apparatus is on a vehicle and acquires position information broadcast from the roadside device by wireless communication. The position information is about a position of the roadside device. The vehicle-mounted apparatus decides whether individual wireless connection is performed between the roadside device and the vehicle-mounted apparatus based on roadside device information. The roadside device information includes the position information about the position of the roadside device. Connection or disconnection of individual wireless connection is performed between the vehicle-mounted apparatus and the roadside device based on the decision. Periphery information of the roadside device is acquired from the roadside device during the individual wireless connection in response to the individual wireless connection being connected.

the first operations further include:
number: 3
text: The communication system according to Claim 1, wherein
the second operations further include:
acquiring information of a planned traveling route of the vehicle, and
the individual wireless connection is decided to be performed between the roadside device and the vehicle-mounted apparatus in a case where the planned traveling route is related with the roadside device information.
number: 4
text: The communication system according to Claim 1, further comprising:
number: 5
text: The communication system according to Claim 1, wherein the position information about the position of the roadside device is two-dimensional information.
number: 6
text: The communication system according to Claim 1, wherein the position information about the position of the roadside device is three-dimensional information.
number: 7
text: The communication system according to Claim 1, wherein the sensor is a Global Positioning Sensor that acquires the position information about the position of the roadside device.
number: 8
text: The communication system according to Claim 1, wherein
the sensor is a distance measurement sensor, and
the position information about the position of the roadside device is acquired by measuring a distance between the roadside device and a surrounding object, and by correlating the measured distance and the surrounding object with the map information.
number: 9
text: The communication system according to Claim 1, wherein
the sensor is a camera, and
the position information about the position of the roadside device is acquired by estimating a distance and a direction between the roadside device and a surrounding object, which are acquired via the camera, and by correlating the estimated distance and the direction with the map information.
number: 10
text: The communication system according to Claim 1, wherein the periphery information identifies an obstacle, specifies whether the obstacle is a moving body, and specifies a kind of the moving body.
number: 11
text: The communication system according to Claim 1, wherein
the periphery information identifies an obstacle,
the roadside device estimates a position of the obstacle and collates the position of the obstacle with the map information of the roadside device, and
when the estimated position of the obstacle matches a position of a non-moving object in the map information, the periphery information specifies the obstacle as the non-moving object.
number: 12
text: The communication system according to Claim 1, wherein
the periphery information identifies an obstacle,
the roadside device estimates a position of the obstacle and collates the position of the obstacle with the map information of the roadside device, and
when the estimated position of the obstacle does not match a position of a non-moving object in the map information, the periphery information specifies the obstacle as a temporarily placed object.
number: 13
text: The communication system according to Claim 1, wherein
the second operations further include:
acquiring information of a planned traveling route of the vehicle,
the roadside device information includes the position information about the position of the roadside device and range information about a detection range of the roadside device, and
the individual wireless connection is decided to be connected or disconnected based on whether the detection range includes the planned traveling route.
number: 14
text: The communication system according to Claim 1, wherein
the second operations further include:
acquiring information of a planned traveling route of the vehicle, and
the individual wireless connection is decided to be connected or disconnected based on whether the planned traveling route is more than a distance from the position of the roadside device at which the individual wireless connection becomes unstable.
number: 15
text: The communication system according to Claim 1, wherein
the second operations further include:
acquiring information of a planned traveling route of the vehicle,
the roadside device information includes the position information about the position of the roadside device and scanning information about a scanning radius of the roadside device, and
the individual wireless connection is decided to be connected or disconnected based on whether the scanning radius includes the planned traveling route.
number: 16
text: A vehicle-mounted apparatus that is capable of wireless connection with a roadside device which is on, above, or below a road, the vehicle-mounted apparatus being on a vehicle, the vehicle-mounted apparatus comprising:
number: 17
