VEHICLE INFORMATION MANAGEMENT SYSTEM
First Claim
1. A vehicle information management system that manages diagnostic data that indicates a vehicle state, the vehicle information management system comprising:
- a plurality of parameter detectors each arranged to detect a parameter related to the vehicle state;
an abnormality specifying unit programmed to specify a type of an abnormality generated in the vehicle based on the parameters detected by the plurality of parameter detectors;
a diagnostic data producing unit programmed to produce the diagnostic data based on the parameters detected by the plurality of parameter detectors when the type of the abnormality is specified by the abnormality specifying unit;
a storage including a storage region arranged to store abnormality data including the diagnostic data, type information that indicates the type of the abnormality, and occurrence number information that indicates a number of occurrences of an abnormality specified by the type information; and
an updating unit programmed to change the occurrence number information to latest information and to overwrite and save new diagnostic data in the storage region when the type of the abnormality is specified by the abnormality specifying unit and the new diagnostic data is produced, if the abnormality data of the same type as the specified type is already stored in the storage region.

Abstract
In a vehicle information management system, a storage includes a storage region arranged to store abnormality data that includes diagnostic data, type information indicating a type of an abnormality, and occurrence number information that indicates the number of occurrences of each abnormality specified by the type information. When the type of an abnormality is specified by an abnormality specifying unit and a new diagnostic data is produced and if the abnormality data of the same type as the specified type is already stored in the storage region in the storage, an updating unit changes the occurrence number information to the latest information and overwrites and saves the diagnostic data in the storage region already stored with the abnormality data of the same type as the specified type.

10. A vehicle information management method for managing diagnostic data that indicates a vehicle state, the method comprising the steps of:
-
detecting a parameter related to the vehicle state; producing the diagnostic data based on the detected parameter; specifying a type of an abnormality generated in the vehicle based on the diagnostic data; and changing occurrence number information to latest information and then overwriting and saving a new diagnostic data in a storage region when the new diagnostic data is produced and abnormality data of the same type as the specified type is already stored in the storage region.
