Information processing device and information processing method
View Patent ↗An information processing device includes a communication unit and a controller. The communication unit performs data communication with another vehicle present in a periphery of a host vehicle. The controller controls the data communication performed by the communication unit. The communication unit has a normal mode, and a directivity mode in which directivity of wireless communication is controlled to a greater extent than in the normal mode so that data communication can be performed with another vehicle at a position at which data communication cannot be performed in the normal mode. The controller receives server data from a server that includes information pertaining to the other vehicle present at the position at which data communication cannot be performed in the normal mode. The controller controls the directivity of the wireless communication of the communication unit based on the information pertaining to the other vehicle from the server.
1 . An information processing device comprising:
a communication unit configured to be mounted on a first moving body and to perform data communication with a second moving body present around the first moving body and with a server that distributes prescribed server data; and
a controller configured to control the data communication performed by the communication unit,
the communication unit having a normal mode and a directivity mode in which directivity of wireless communication can be controlled to a greater extent than in the normal mode to make possible the data communication with the second moving body being present at a position at which the data communication is impossible to perform in the normal mode,
the controller being configured to
receives server data from the server that includes information pertaining to the second moving body present at the position at which the data communication is impossible to perform in the normal mode, the information relating to the second moving body includes current position information pertaining to the second moving body, and
control the directivity of the wireless communication performed by the communication unit based on the information pertaining to the second moving body that is included in the server data.
2 . The information processing device according to claim 1 , wherein
the controller is configured to
specify the second moving body that could cross a path of the first moving body as a designated moving body based on the information relating to the second moving body that is included in the server data, and
control the directivity of the wireless communication performed by the communication unit based on information pertaining to the designated moving body.
3 . The information processing device according to claim 2 , wherein
the information relating to the second moving body further includes speed information pertaining to the second moving body, and
the controller is configured to specify the designated moving body based on the current position information and the speed information pertaining to the second moving body and current position information and speed information pertaining to the first moving body.
4 . The information processing device according to claim 3 , wherein
the controller is configured to determine a priority order for the second moving body that could cross the path of the first moving body based on the current position information and the speed information pertaining to the second moving body and the current position information and the speed information pertaining to the first moving body, and then specify the designated moving body based on the priority order.
5 . The information processing device according to claim 3 , wherein
the communication unit is configured to perform the data communication with a roadside unit disposed in a periphery of a road on which the first moving body is traveling; and
the controller is configured to control the directivity of the wireless communication performed by the communication unit so as to be oriented toward the roadside unit, which transmits distribution data that includes information pertaining to the designated moving body.
6 . The information processing device according to claim 2 , wherein
the designated moving body is
a second moving body having a route that passes through an intersection included in a route on which the first moving body will travel in the future, or
a second moving body having a route for traveling in a passing lane on a road on which the first moving body is traveling.
7 . The information processing device according to claim 2 , wherein
the controller is configured to control the directivity of the wireless communication performed by the communication unit based on the position information pertaining to the designated moving body.
8 . The information processing device according to claim 7 , wherein
the controller is configured to control the directivity of the wireless communication performed by the communication unit so as to be oriented toward the designated moving body.
9 . The information processing device according to claim 2 , wherein
the controller is configured to
determine whether or not the first moving body is passing, and
perform a process to specify the designated moving body upon determining that the first moving body is passing.
10 . The information processing device according to claim 1 , wherein
the communication unit is configured to
form a beam at every bearing in the normal mode, and
form a beam having directivity in the directivity mode; and
the controller is configured to control the directivity of the beam when controlling the directivity of the wireless communication performed by the communication unit.
11 . An information processing method for an information processing device comprising a communication unit configured to be mounted on a first moving body and performs data communication with a second moving body around the first moving body and with a server that distributes prescribed server data, and a controller configured to control the data communication performed by the communication unit, the communication unit having a normal mode and a directivity mode in which directivity of wireless communication can be controlled to a greater extent than in the normal mode to make possible the data communication with the second moving body being present at a position at which data communication is impossible to perform in the normal mode,
the information processing method comprising:
receiving server data from the server that includes information pertaining to the second moving body present at which the data communication is impossible to perform in the normal mode, the information relating to the second moving body includes current position information pertaining to the second moving body, and
controlling the directivity of the wireless communication performed by the communication unit based on the information pertaining to the second moving body that is included in the server data.
