Patent Number: 
Section: claims

1. A vehicle operation data collection apparatus comprising:a memory configured to store operation data of a plurality of vehicles acquired from the plurality of vehicles; anda processor programmed toevaluate excess or deficiency of operation data of the plurality of vehicles stored in the memory for each of abnormality types, on the basis of accuracy information of classification obtained when classifying the abnormality types occurring in the plurality of vehicles by machine learning, using operation data of the plurality of vehicles stored in the memory;extract, from the plurality of vehicles, a vehicle suitable for acquiring data of an abnormality type evaluated as data deficiency from a database accumulating maintenance history information of the plurality of vehicles as a collection target vehicle; anddistribute a collection command instructing collection of operation data to the extracted collection target vehicle; andreceive the operation data from the extracted collection target vehicle. 2. A vehicle operation data collection system comprising:a memory configured to store operation data of a plurality of vehicles acquired from the plurality of vehicles; anda vehicle operation data collection apparatus which has a processor programmed to evaluate excess and deficiency of the operation data of the plurality of vehicles accumulated in the memory for each of abnormality types, on the basis of accuracy information of classification obtained when classifying the abnormality types occurring in the plurality of vehicles by machine learning, using the operation data of the plurality of vehicles accumulated in the memory, extract, from the plurality of vehicles, a vehicle suitable for acquiring data of an abnormality type evaluated as data deficiency from a database accumulating maintenance history information of the plurality of vehicles as a collection target vehicle, distribute an operation data collection command instructing collection of operation data to the extracted collection target vehicle, and receive the operation data from the extracted collection target vehicle; andthe plurality of vehicles which has a communication unit which communicates with the vehicle operation data collection apparatus, one or more sensors attached to one or more components constituting the plurality of vehicles, and an in-vehicle terminal which acquires sensor data from the sensor specified by the operation data collection command and collects the acquired sensor data as operation data of the plurality of vehicles when receiving the operation data collection command. 3. A vehicle operation data collection method which causes a computer connected communicably to a plurality of vehicles to execute the steps of:accumulating operation data of a plurality of vehicles acquired from the plurality of vehicles in a storage device;evaluating excess or deficiency of operation data of the plurality of vehicles accumulated in the storage device for each of abnormality types, on the basis of accuracy information of classification obtained when classifying the abnormality types occurring in the plurality of vehicles by machine learning, using operation data of the plurality of vehicles accumulated in the storage device;extracting, from the plurality of vehicles, a vehicle suitable for acquiring data of an abnormality type evaluated as data deficiency in the evaluating excess or deficiency of operation data of the plurality of vehicles from a database accumulating maintenance history information of the plurality of vehicles, as a collection target vehicle; anddistributing a collection command instructing collection of operation data to the extracted collection target vehicle; andreceiving the operation data from the extracted collection target vehicle.
