Abstract

When repair/replacement information is acquired by a repair/replacement information acquisition device, feature quantities of vehicle state information acquired by an vehicle state information acquisition device are detected, and a content of repair or parts replacement is estimated using the detected feature quantities of the vehicle state information, and supervised training data. If the result of the estimation accords with the repair/replacement information acquired by the repair/replacement information acquisition device, a storage device is controlled so that the combination of the detected feature quantities of the vehicle state information and the repair/replacement information acquired by the repair/replacement information acquisition device is added to the supervised training data.

Claims

1. A system for managing vehicle repair/replacement information comprising:

a repair/replacement information acquisition device that acquires repair/replacement information that represents a content of repair or parts replacement that has been actually performed to remove an abnormality of a vehicle;

a vehicle state information acquisition device that acquires vehicle state information at an occurrence of abnormality of the vehicle, said vehicle state information representing a state of the vehicle;

a storage device that stores the acquired vehicle state information and the acquired repair/replacement information as a plurality of units of supervised training data in each of which the vehicle state information and the repair/replacement information are associated; and

an information processing device that detects a feature of the vehicle state information of each unit of supervised training data stored in the storage device, and that retains a unit of supervised training data if the content of repair or parts replacement described by the repair/replacement information contained in the unit of supervised training data accords with the content of repair or replacement described by the repair/replacement information contained in another unit of supervised training data stored whose detected feature is most closely correlated to the detected feature of the unit, and does not use a unit of supervised training data if the content of repair or parts replacement described by the repair/replacement information contained in the unit of supervised training data does not accord with the content of repair or replacement described by the repair/replacement information contained in another unit of supervised training data stored whose detected feature is most closely correlated to the detected feature of the unit.

2. The system for managing repair/replacement information according to claim 1, wherein

the vehicle state information is time-series data that has a plurality of items, and the information processing device detects, as the feature of the vehicle state information, a changed-item pattern occurring at a time point of change of the vehicle state information acquired by the vehicle state information acquisition device.

3. The system for managing repair/replacement information according to claim 1, wherein

the information processing device performs, at a predetermined timing, a process of deleting each piece of data which is contained in the supervised training data stored in the storage device, and whose correlation with other pieces of data is low.

4. The system for managing repair/replacement information according to claim 1, further comprising

an information providing device that provides information for a user, wherein when the vehicle state information acquisition device acquires the vehicle state information, the information processing device performs a function of detecting the feature of the vehicle state information acquired by the vehicle state information acquisition device, and estimating the content of repair or parts replacement by using the detected feature of the vehicle state information, and the supervised training data, and controlling the information providing device so as to provide the user with a result of estimation of the content of repair or parts replacement.

5. A device for managing vehicle repair/replacement information, comprising:

a storage device that stores vehicle state information and repair/replacement information as a plurality of units of supervised training data in each of which the vehicle state information and the repair/replacement information are associated; and

an information processing device that detects a feature of the vehicle state information of each unit of supervised training data stored in the storage device, and that retains a unit of supervised training data if a content of repair or parts replacement described by the repair/replacement information contained in the unit of supervised training data accords with the content of repair or replacement described by the repair/replacement information contained in another unit of supervised training data stored whose detected feature is most closely correlated to the detected feature of the unit, and does not use a unit of supervised training data if the content of repair or parts replacement described by the repair/replacement information contained in the unit of supervised training data does not accord with the content of repair or replacement described by the repair/replacement information contained in another unit of supervised training data stored whose detected feature is most closely correlated to the detected feature of the unit.

6. A method of processing a plurality of units of supervised training data which are stored in a storage device and in each of which vehicle state information and repair/replacement information are associated, comprising:

detecting a feature of the vehicle state information of each unit of supervised training data;

determining, with regard to each unit of supervised training data, whether or not a content of repair or parts replacement described by the repair/replacement information contained in the unit of supervised training data accords with the content of repair or replacement described by the repair/replacement information contained in another one of the units stored whose detected feature is most closely correlated to the detected feature of the unit; and

retaining the unit of supervised training data if the content of repair or replacement described in the unit accords with the content of repair or replacement described in the another one of the units, and not using the unit of supervised training data if the content of repair or replacement described in the unit does not accord with the content of repair or replacement described in the another one of the stored units.

7. A system for managing vehicle abnormality cause information comprising:

an abnormality cause information acquisition device that acquires abnormality cause information, said abnormality cause information showing a cause of an abnormality of a vehicle;

a vehicle state information acquisition device that acquires vehicle state information at an occurrence of abnormality of the vehicle, said vehicle state information representing a state of the vehicle;
