Abstract

Provided is a vehicle information management system having a vehicle-mounted information terminal and a management center. The vehicle-mounted information terminal collects vehicle information including charge information indicating a charging status of a storage battery. The storage battery is mounted on a vehicle configured from an electric vehicle or a hybrid vehicle. The management center manages the vehicle information uploaded from the vehicle-mounted information terminal. The vehicle-mounted information terminal is configured so as to monitor a vehicle state. The vehicle-mounted information terminal uploads the vehicle information to the management center when the vehicle state is shifted to an upload state as a previously defined state on the basis of a monitoring result which is a result of the monitoring.

a change in a vehicle bus, which connects the vehicle-mounted information terminal and a control system of the vehicle to each other within the vehicle by a bus from an activated state to an inactivated state;

a change from an ignition-OFF state to an ignition-ON state;

a change in the accessory position from an OFF state to an ON state; and

a change in the vehicle bus from the inactivated state to the activated state.

4. The vehicle information management system according to claim 1, wherein the vehicle information includes information indicating at least one of:

a remaining charging time required for charging to be completed when the secondary battery is in a state of charging;

a connection state between a power supply plug that supplies power to the secondary battery and the secondary battery;

a deteriorated state of the secondary battery;

a possible vehicle travel distance correlated to the charging state of the secondary battery; and

a charging rate of the secondary battery.

5. The vehicle information management system according to claim 1, wherein

the vehicle-mounted information terminal has a function to add information indicating a delivery time to the vehicle information,

the vehicle-mounted information terminal is configured to upload the vehicle information to which the delivery time is added to the management center, and

the vehicle-mounted information terminal is configured, when an upload error occurs in the vehicle information to the management center, to re-upload the vehicle information that the upload error has occurred to the management center, and sets the delivery time added to the vehicle information upon an initial delivery as the delivery time to be added to the vehicle information to be re-uploaded.

6. The vehicle information management system according to claim 1, wherein

the vehicle information includes a plurality of items indicating the vehicle state,

a plurality of types of conditions are defined as conditions under which the vehicle information is to be uploaded,

one or more items indicating the vehicle state are associated with each of the defined conditions, and

the vehicle-mounted information terminal is configured, in response to shifting of the vehicle state to a corresponding condition, to upload information related to the one or more of items associated to the condition to the management center.

7. The vehicle information management system according to claim 1, wherein

the management center is configured to generate guide information for guiding a user of the vehicle with respect to the vehicle state based on the vehicle information uploaded from the vehicle-mounted information terminal, and

the management center is further configured to deliver the generated guide information to a user information terminal as an information terminal possessed by an owner of the vehicle.
