Abstract:
1. A vehicle communication system, comprising: a transmission node which starts a signal transmission when switching from an OFF state to an ON state; a reception node connected to the transmission node and receiving the signal transmitted through a plurality of communication lines; a junction connector electrically coupled to the plurality of transmission lines and branching the signal into multiple channels; a grounding means electrically coupled to the junction connector and providing a electrical path to ground; a diode in which a direction directed from a negative-side output terminal of the transmission node to a positive-side output terminal thereof becomes a forward direction, the diode being disposed between the positive-side output terminal and the negative-side output terminal; and a Zener diode in which a direction directed from the negative-side output terminal to the positive-side output terminal becomes a forward direction, a direction from the positive-side output terminal to the negative-side output terminal becomes a reverse direction, and a Zener voltage becomes a reverse voltage when the Zener diode conducts in the reverse direction, in addition to the diode, the Zener diode being disposed between the positive-side output terminal and the negative-side output terminal,
