Abstract
A wire harness configured to connect communication between a first communication unit and a second communication unit includes: a transmission line provided between the first communication unit and the second communication unit, and configured to transmit a signal from at least one of the first communication unit and the second communication unit; and a filter unit provided at a predetermined position of the transmission line, and having a predetermined characteristic.
Claims14
A wire harness configured to connect communication between a first communication unit and a second communication unit, the wire harness comprising:
- a transmission line provided between the first communication unit and the second communication unit, and configured to transmit a signal from at least one of the first communication unit and the second communication unit;
- and
- a filter unit provided at a predetermined position of the transmission line, and having a predetermined characteristic.
A harness identification system comprising:
- a wire harness;
- and
- an identification device configured to identify whether the wire harness is legitimate, wherein
- the wire harness includes:
- a transmission line configured to transmit a signal;
- and
- a filter unit provided at a predetermined position of the transmission line, and having a predetermined characteristic,
- the identification device includes:
- a signal transmission unit configured to transmit an identification signal to the transmission line;
- a signal reception unit configured to receive a reflection waveform of the identification signal;
- and
- an identification unit configured to identify authenticity of the wire harness, based on whether a signal generated by the filter unit and having the predetermined characteristic is included in the received reflection waveform.
An in-vehicle device configured to be mounted in a vehicle, the in-vehicle device comprising:
- a connector to which a wire harness is connected;
- a substrate on which an electronic component is mounted;
- a transmission line configured to transmit a signal between the electronic component and the wire harness;
- and
- a filter unit provided at a predetermined position of the transmission line, and having a predetermined characteristic.
