Vehicle-mounted system and wire harness
View Patent ↗A seat control system includes: a motor unit mounted on a vehicle; a switch unit; a control ECU for controlling these units; a power source box for supplying a power source to the units; a main power source line connected between the units and the control ECU and provided for supplying a power source from a power source box; and a signal line connected between the units and the control ECU. The seat control system further includes: another power source box separate from a power source box for supplying a power source to the units; and a redundant power source line connected between the power source box and the units and provided for supplying a power source from the power source box. The redundant power source line is not connected to the control ECU.
1. A vehicle-mounted system comprising:
an electronic unit formed of one or more electronic devices mounted on a vehicle;
a control unit for controlling the electronic devices;
a first power source configured to supply power to all the electronic devices;
a first power source line connected between the electronic unit and the control unit, the first power source line being provided for supplying the first power source to all the electronic devices constituting the electronic unit;
a signal line connected between the electronic unit and the control unit;
a second power source provided separate from the first power source and configured to supply power to the same electronic devices as the first power source supplies power and as the control unit controls; and
a second power source line connected between the second power source and the electronic unit, the second power source line being provided for supplying the second power source to all the electronic devices constituting the electronic unit, and the second power source line not being connected to the control unit.
2. The vehicle-mounted system according to claim 1 , wherein the first power source line and the second power source line are connected to the electronic units in a state where the first power source line and the second power source line are individually connected to diodes, and terminals of the respective diodes on the other side are connected to each other.
3. The vehicle-mounted system according to claim 2 , further comprising a connection connector mounted on the first power source line, the signal line and the second power source line, and provided for connecting the first power source line, the signal line and the second power source line to the electronic unit, wherein
the diode is incorporated in the connection connector.
4. A wire harness comprising:
a first power source line connected between an electronic unit formed of one or more electronic devices disposed on a vehicle and a control unit for controlling the electronic devices, the first power source line being provided for supplying power from a first power source to all the electronic devices constituting the electronic unit;
a signal line connected between the electronic unit and the control unit;
a second power source line connected between a second power source provided separate from the first power source and the electronic unit, the second power source line being provided for supplying power from the second power source to all the electronic devices constituting the electronic unit, and the second power source line not being connected to the control unit.
