Information processing device, vehicle control unit, and road information distribution method
In a road information distribution system, a cloud server detects to road location where an abnormality is occurring based on vehicle location information of a plurality of vehicles or vehicle controlling amount of a plurality of vehicles, and transmits an abnormal road location to a vehicle before identifying a cause of the abnormality. The road information distribution system then notifies the abnormal road location to a driver of the vehicle when the vehicle approaches a predetermined distance from the abnormal road location.
1. An information processing device comprising:
a communication device that communicates with vehicles; and
one or more processors, wherein:
the communication device receives, from one of the vehicles, location information indicating a traveling location of a particular vehicle on a road,
the one or more processors detect an abnormal road location, which is a road location where an abnormality is occurring, based on location information of a plurality of the vehicles received by the communication device,
the one or more processors identify a cause of the abnormality when the abnormal road location is detected based on information from infrastructure facilities or recognition results of the surrounding environment transmitted by the vehicles that have passed the abnormal road location,
the one or more processors transmit, using the communication device, the abnormal road location to the particular vehicle before identifying the cause of the abnormality, and
the one or more processors transmit, using the communication device, the cause of the abnormality to the particular vehicle when the cause of the abnormality is identified after transmitting the abnormal road location to the particular vehicle.
2. The information processing device according to claim 1 , wherein
the one or more processors detect a location of the road as the abnormal road location where less than a predetermined number of vehicles have traveled within a predetermined time based on the location information transmitted from the plurality of vehicles.
3. The information processing device according to claim 1 , wherein
the one or more processors detect a location of the road as the abnormal road location where a controlling amount of the plurality of vehicles exceeds a predetermined threshold value.
4. The information processing device according to claim 3 , wherein
the controlling amount is at least one of deceleration of the particular vehicle, acceleration of the particular vehicle, and steering amount of the particular vehicle.
5. The information processing device of claim 1 , wherein
the one or more processors terminate the identification of the cause of the abnormality if the abnormality is resolved before the cause of the abnormality is identified.
6. A road information distribution method using a communication device, one or more processors, and a vehicle control unit comprising:
receiving, by the communication device, location information from a vehicle indicating a traveling location of the vehicle on a road;
detecting an abnormal road location, which is a location of a road where an abnormality is occurring, based on the received location information of a plurality of vehicles;
identifying a cause of the abnormality when the abnormal road location is detected based on information from infrastructure facilities or recognition results of the surrounding environment received from the plurality of vehicles that have passed the abnormal road location;
transmitting the detected abnormal road location to the vehicle before identifying a cause of the abnormality; and
notifying the abnormal road location to a driver of the vehicle when the vehicle approaches a predetermined distance from the abnormal road location.
