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 comprising:

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 a user interface of the in-vehicle information terminal 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;

a transmission prevention unit configured to, when the read-out operation information is input through the user interface, prevent transmission of the abnormality information to the server; and

a prevention cancel unit configured to cancel the prevention of the transmission of the abnormality information when a vehicle comprising the abnormality detection device has run a predetermined running distance from a running distance when the transmission of the abnormality information is prevented by the transmission prevention unit.

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

a storage prevention unit configured to, when the read-out operation information is input through the user interface, 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, wherein when the read-out operation information is input through the user interface, 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, wherein the user interface is in the in-vehicle information terminal or a user interface of a navigation device.

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

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

6. The abnormality detection device according to claim 1, wherein 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. A method of detecting abnormality comprising:

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

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

detecting whether an operation input through a user interface of an in-vehicle information terminal is a predetermined operation inputting read-out operation information;

reading, when the read-out operation information is input through the user interface, the abnormality information stored in the storage unit; and

prohibiting, when the read-out operation information is input through the user interface, transmission of the abnormality information to the server by a transmission prevention unit; and

cancelling the prevention of the transmission of the abnormality information when a vehicle comprising the abnormality detection device has run a predetermined running distance from a running distance when the transmission of the abnormality information is prevented by the transmission prevention unit.

8. An abnormality information transmission system comprising:

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, wherein;

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 a user interface of the in-vehicle information terminal 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 user interface, prevent transmission of the abnormality information to the server; and

a prevention cancel unit configured to cancel the prevention of the transmission of the abnormality information when a vehicle comprising the abnormality detection device has run a predetermined running distance from a running distance when the transmission of the abnormality information is prevented by the transmission prevention unit.
