Vehicle-use data backup system and on-vehicle terminal apparatus comprised in the system
First Claim
1. A vehicle-use data backup system for backing up and storing vehicle-use data used by an on-vehicle terminal apparatus in a backup center which handles data communication with the vehicle, said system comprising:
- an on-vehicle storage means provided on said on-vehicle terminal apparatus which stores custom data unique to the vehicle along with other standard data as said vehicle-use data; and
a backup storage means which is provided on said backup center which individually stores said vehicle-use data of each vehicle; and
said backup storage means stores said custom data and also stores identification codes identifying the standard data.

Abstract
An information center backs up the vehicle-use data of an on-vehicle terminal apparatus. The vehicle-use data used by the on-vehicle terminal apparatus is classified into standard data or custom data. The standard data is used in the same manner by numerous vehicles, while custom data is unique to each vehicle. The custom data is sent unchanged to the information center but, for the standard data, identification codes are sent rather than the raw standard data. This data is backed up and stored in the information center, where they remain available for retrieval should the data on the vehicle side be damaged. Because the volume of backup data is reduced, the communication time can be shortened and the required backup memory capacity in the information center can be reduced.
