Information processing device, information processing method, and server

An information processing method of an information processing device comprising:

• a communication unit mounted on a moving object and communicates with the moving object and another moving object;
• a GPS receiver that detects a position of the moving object;
• a sensor comprising a camera and a light detection and ranging (LiDAR) system, wherein the sensor is configured to detect and identify a type of an object on or around a road as object data;
• and
• a controller that controls the communication performed by the communication unit, the method comprising:
• acquiring a first future position where the moving object travels in the future based on, at least in part, the position of the moving object;
• acquiring a second future position where the another moving object travels in the future;
• acquiring a first future route that the moving object will travel in the future and a second future route that the another moving object will travel in the future;
• acquiring a positional relationship between the moving object and the another moving object based on the first future route and the second future route;
• acquiring map information based on the first future route and the second future route;
• determining a presence and a type of a shielding object including a vehicle based on the positional relationship, map information, and object data;
• determining a corrected radio wave intensity between the moving object and the another moving object along the first future route and the second future route, wherein determining the corrected radio wave intensity comprises adjusting a radio intensity with a shielding attenuation factor based on the presence and the type of the shielding object;
• determining a data transmission/reception rate that the moving object will transmit to or receive from the another moving object;
• determining, based on the data transmission/reception rate, a minimum reception power;
• determining, by comparison of the corrected radio wave intensity to a threshold based on the minimum reception power, whether direct communication between the moving object and the another moving object is difficult in a section of the first and second future routes;
• and
• executing indirect communication at a timing corresponding to the section in response to a determination that direct communication is difficult in the section,
• wherein steps for executing indirect communication comprise:
• receiving access information for connection to a server,
• connecting to the server using the access information, wherein connecting to the server comprises receiving and transmitting a test signal from and to the server to confirm the connection, and
• transmitting or receiving data to or from the another moving object via the server.

A server for indirect communication between a moving object and another moving object via a fixed and non-moving communication device, the server being configured to:

• acquire a first future position where the moving object travels in the future based on, at least in part, a position of the moving object, wherein the position is detected with a GPS receiver of the moving object;
• acquire a second future position where the another moving object travels in the future;
• acquire a first future route that the moving object will travel in the future and a second future route that the another moving object will travel in the future;
• acquire data from a sensor comprising a camera and a light detection and ranging (LiDAR) system, wherein the sensor is configured to detect and identify a type of an object on or around a road as object data;
• acquire a positional relationship between the moving object and the another moving object based on the first future route and the second future route;
• acquire map information based on the first future route and the second future route;
• determine a presence and a type of a shielding object including a vehicle based on the positional relationship, map information, and object data;
• determine a corrected radio wave intensity between the moving object and the another moving object along the first future route and the second future route, wherein determining the corrected radio wave intensity comprises adjusting a radio intensity with a shielding attenuation factor based on the presence and the type of the shielding object;
• determine a data transmission/reception rate that the moving object will transmit to or receive from the another moving object;
• determine, based on the data transmission/reception rate, a minimum reception power;
• determine, by comparison of the corrected radio wave intensity to a threshold based on the minimum reception power, whether direct communication between the moving object and the another moving object is difficult in a section of the first and second future routes;
• and
• execute indirect communication at a timing corresponding to the section in response to a determination that direct communication is difficult in the section, wherein steps to execute indirect communication comprise:
• transmitting access information for connection to the server to one or more of the moving object and the another moving object,
• connecting, by a reception of the access information, to the moving object and the another moving object, wherein connecting to the moving object and the another moving object comprises transmitting and receiving a test signal to each of the moving object and the another moving object to confirm the connection, and
• transmitting data between the moving object and the another moving object.
