VEHICLE INFORMATION STORAGE APPARATUS
First Claim
1. A vehicle information storage apparatus comprising:
- a status information acquiring unit acquiring a dataset of status information items of a vehicle;
a controlling unit determining information data to be used for investigating a cause of a malfunction based on the dataset of status information items acquired by the status information acquiring unit and storing the determined information data in a prescribed storage medium; and
a range table storage unit storing a range table describing a range of the information data to be used for investigating a cause of a malfunction, the range being determined based on when the malfunction started and the information data being determined from the dataset of status information items acquired by the status information acquiring unit, whereinthe controlling unit determines a time point at which the malfunction started in the vehicle, the time point being a predetermined time period before a time point when the dataset of status information items acquired by the status information acquiring unit have been within a predetermined range for a predetermined period of time and further determines the information data to be used for investigating the cause of the malfunction from among the dataset of status information items acquired by the status information acquiring unit based on the determined time point when the malfunction started and data of the range table.
