Abstract
A transmission ECU on a transmission side and reception ECUs on a reception side are connected through communication lines and junction connectors. A delay circuit is provided in each of the junction connectors on the side of the reception ECUs. One end of the delay circuit is connected to the communication line on the side of the transmission ECU and the other end of the same is connected to the communication line on the side of the reception ECU. The communication lines on the both ends of the delay circuit are grounded through termination resistors.
Claims5
A vehicle communication system, comprising:
- a transmission node for transmitting a signal;
- a plurality of reception nodes for receiving the signal;
- a first communication line having a first end connected to the transmission node and a second end connected to a branching means for branching the first communication line into a plurality of second communication lines, the second communication lines connected to the plurality of reception nodes;
- a delay circuit having a first end connected to the second end of the first communication line and a second end connected to the second communication lines;
- a first termination resistor connecting the first end of the delay circuit to ground;
- and
- a second termination resistor connecting the second end of the delay circuit to ground,
- wherein an impedance that mitigates oscillations in the signal received by the plurality of reception nodes caused by a transition in the signal transmitted by the transmission node is generated between the first termination resistor and the second termination resistor.
