Abstract

An abnormality detection device is disclosed that includes a storage unit configured to, when abnormality of an in-vehicle device is detected, store abnormality information of the abnormality; a transmission unit configured to transmit the abnormality information to a server; an in-vehicle information terminal configured to, when driving support information is provided to an occupant and read-out operation information is input through an operation section, read out the abnormality information stored in the storage unit; and a transmission prevention unit configured to, when the read-out operation information is input through the operation section, prevent transmission of the abnormality information to the server.

Claims

1. An abnormality detection device including characterized by:

a storage unit configured to, when abnormality of an in-vehicle device is detected, store abnormality information of the abnormality;

a transmission unit configured to transmit the abnormality information to a server;

an in-vehicle information terminal configured to provide driving support information to an occupant, detect whether an operation input through an operation section is a predetermined operation inputting read-out operation information and, when detecting the predetermined operation, read out the abnormality information stored in the storage unit; and

a transmission prevention unit configured to, when the read-out operation information is input through the operation section, prevent transmission of the abnormality information to the server.

2. The abnormality detection device according to claim 1, further characterized by:

a storage prevention unit configured to, when the read-out operation information is input through the operation section, prevent storage of the abnormality information, wherein

the transmission of the abnormality information is prevented by the transmission prevention unit.

3. The abnormality detection device according to claim 1, characterized in that:

when the read-out operation information is input through the operation section, a detection of abnormality of an in-vehicle device is prevented without preventing the transmission of the abnormality information by the transmission prevention unit.

4. The abnormality detection device according to claim 1, characterized in that:

the operation section is an in-vehicle information terminal or a user interface of a navigation device.

5. The abnormality detection device according to claim 1, further characterized by:

a display unit configured to display the abnormality information read out from the storage unit.

6. The abnormality detection device according to claim 1, characterized in that:

the abnormality information includes at least one of a diagnosis code indicating a content of the abnormality using a symbol, a number, or combination of a symbol and a number, detection information detected from the in-vehicle device when the abnormality is detected, and information whether an alarm lamp is turned ON.

7. An abnormality detection device characterized by:

a storage unit configured to, when abnormality of an in-vehicle device is detected, store abnormality information of the abnormality;

a transmission unit configured to transmit the abnormality information to a server; and

an in-vehicle information terminal configured to provide driving support information to an occupant, detect whether an operation input through an operation section is a predetermined operation inputting read-out operation information and, when detecting the predetermined operation, read out the abnormality information stored in the storage unit;

the abnormality detection device characterized in that;

when the read-out operation information is input through the operation section, the transmission unit transmits the abnormality information to the server, the abnormality information including information indicating that abnormality is not detected.

8. A method of detecting abnormality characterized by the steps of:

a storing step of when abnormality of an in-vehicle device is detected, storing abnormality information of the abnormality in a storage unit;

a transmitting step of transmitting the abnormality information to a server by a transmission unit;

a detecting step of detecting whether an operation input through an operation section is a predetermined operation inputting read-out operation information

a reading out step of, when the read-out operation information is input through the operation section, reading out the abnormality information stored in the storage unit; and

a prohibiting step of, when the read-out operation information is input through the operation section, preventing transmission of the abnormality information to the server by a transmission prevention unit.

9. An abnormality information transmission system including:

an abnormality detection device configured to detect abnormality of an in-vehicle device and transmit abnormality information of the abnormality; and

a server configured to receive the abnormality information of the abnormality detection device, the system characterized in that;

the abnormality detection device comprises

a storage unit configured to, when abnormality of an in-vehicle device is detected, store abnormality information of the abnormality;

a transmission unit configured to transmit the abnormality information to a server;

an in-vehicle information terminal configured to provide driving support information to an occupant, detect whether an operation input through an operation section is a predetermined operation inputting read-out operation information and, when detecting the predetermined operation, read out the abnormality information stored in the storage unit; and

a transmission prevention unit configured to, when the read-out operation information is input through the operation section, prevent transmission of the abnormality information to the server.

10. An abnormality information transmission system including:

an abnormality detection device configured to detect abnormality of an in-vehicle device and transmit abnormality information of the abnormality; and

a server configured to receive the abnormality information of the abnormality detection device, the system characterized in that

the abnormality detection device comprises;

a storage unit configured to, when abnormality of an in-vehicle device is detected, store abnormality information of the abnormality;

an in-vehicle information terminal configured to provide driving support information to an occupant, detect whether an operation input through an operation section is a predetermined operation inputting read-out operation information and, when detecting the predetermined operation, read out the abnormality information stored in the storage unit; and

a transmission unit configured to, when the read-out operation information is input through the operation section, transmit the abnormality information to the server, the abnormality information including flag information indicating that abnormality is not detected, and

the server refers to the flag information to select the abnormality information to be used for analysis of the abnormality.
