Abstract

A bicycle electrical system diagnostic device is provided for a bicycle electrical system in which several electric devices are connected. The diagnostic device includes a connecting section and an electric device recognizing section. The connecting section is configured to be connected to and disconnected from the electrical system. The electric device recognizing section is configured to communicate with the electrical system and recognize any of the electric devices while the connecting section is electrically connected to anyone of the electric devices.

Claims

1. A bicycle electrical system diagnostic device for a bicycle electrical system in which a plurality of electric devices are connected, the diagnostic device comprising:

a connecting section configured to be connected to and disconnected from the electrical system; and

an electric device recognizing section configured to communicate with the electrical system and recognize any of the electric devices while the connecting section is electrically connected to anyone of the electric devices.

2. The bicycle electrical system diagnostic device as recited in claim 1, wherein

the connecting section is configured to be connected directly to any one of the electric devices or to be connected in between the electric devices.

3. The bicycle electrical system diagnostic device as recited in claim 1, further comprising

an indicating section configured to indicate an electric device recognized by the electric device recognizing section.

4. The bicycle electrical system diagnostic device as recited in claim 1, further comprising

a problem diagnosing section configured to diagnose if one of the electric devices recognized by the electric device recognizing section has failed.

5. The bicycle electrical system diagnostic device as recited in claim 4, wherein

the indicating section indicates a failed electric device upon the problem diagnosing section determining that a problem exists in one of the electric devices.

6. The bicycle electrical system diagnostic device as recited in claim 4, wherein

the problem diagnosing section determines if an electrical component contained in one of the electric devices has failed.

7. The bicycle electrical system diagnostic device as recited in claim 6, wherein

the indicating section indicates an electrical component that the problem diagnosing section has determined to have failed upon the problem diagnosing section determining that a problem exists in one of the electric devices.

8. The bicycle electrical system diagnostic device as recited in claim 4, wherein

the indicating section indicates a cause of problem upon the problem diagnosing section determining that a problem exists in one of the electric devices.

9. The bicycle electrical system diagnostic device as recited in claim 4, wherein

the indicating section indicates a repair technique corresponding to the problem upon the problem diagnosing section determining that a problem exists in one of the electric devices.

10. The bicycle electrical system diagnostic device as recited in claim 1, wherein

the connecting section is connected to the electrical system using a power line communication line of one of the electric devices of the electrical system.

11. The bicycle electrical system diagnostic device as recited in claim 10, wherein

the connecting section is configured to be connected to a power line communication terminal of one of the electric devices of the electrical system.

12. The bicycle electrical system diagnostic device as recited in claim 1, wherein

the electric device includes a communication cable.
