Abstract

A vehicular circuit body provided in a vehicle, includes: a trunk line that extends in at least a front-and-rear direction of the vehicle; and a plurality of control boxes that are provided in the trunk line, in which the trunk line includes power source lines of two systems and a communication line.

First claim

What is claimed is:

1. A vehicular circuit body provided in a vehicle, comprising:
a trunk line that extends in at least a front-and-rear direction of the vehicle; and
a plurality of control boxes that are provided in the trunk line,
wherein the trunk line includes power source lines of two systems respectively having a predetermined current capacity and a communication line having a predetermined communication capacity,
wherein the power source lines of two systems extend between the control boxes,
wherein each of the power source lines extends into a first control box of the plurality of control boxes,
wherein the trunk line includes a plurality of terminals, each of the terminals is connected to a respective one of the power sources lines at a location on the respective one of the power source lines that is inside the first control box, and each of the terminals is in electrical communication with the first control box,
wherein the first control box includes a circuit board and a plurality of mating terminals electrically connected to the circuit board, and
wherein each of the terminals includes,
a flat plate portion that abuts the respective one of the power source lines, and
a mating portion that engages a respective one of the mating terminals.

2. The vehicular circuit body according to claim 1 ,
wherein the power source lines of two systems transmit power of the same voltage.

3. The vehicular circuit body according to claim 1 ,
wherein the power source lines of two systems transmit power of different voltages.

4. The vehicular circuit body according to claim 1 ,
wherein a second control box of the plurality of control boxes is located further toward a downstream side than the first control box with respect to a power source, and
wherein the first control box transmits power to the second control box by using only one of the power source lines of two systems.

5. The vehicular circuit body according to claim 1 , further comprising:
a branch line that is connected to an accessory provided in the vehicle.

6. The vehicular circuit body according to claim 5 ,
wherein one end of the branch line is connected to one of the control boxes.

7. The vehicular circuit body according to claim 1 ,
wherein the power source lines of two systems extend in parallel.

8. The vehicular circuit body according to claim 1 ,
wherein the power source lines of two systems are stacked on each other.

9. The vehicular circuit body according to claim 1 , further comprising:
a main power source; and
a sub-power source,
wherein a first line of the power source lines of two systems is electrically connected to the main power source, and
wherein a second line of the power source line of two systems is electrically connected to the sub-power source.

10. The vehicular circuit body according to claim 9 ,
wherein power from the main power source enters the trunk line via a first one of the control boxes, and
wherein power from the sub-power source line enters the trunk line via a second one of the control boxes.

11. The vehicular circuit body according to claim 10 ,
wherein the first line of the power source lines of two systems are configured to transmit power from the first one of the control boxes to a third one of the control boxes, and
wherein the second line of the power source lines of two systems are configured to transmit power from the second one of the control boxes to the third one of the control boxes.

12. The vehicular circuit body according to claim 6 ,
wherein the first control box includes a controller that is configured to,
identify the accessory from a plurality of accessory kinds,
select a type of power supply from a plurality of power supply types, and
supply the type of power supply selected by the first control box to the accessory.

13. The vehicular circuit body according to claim 12 ,
wherein the first control box includes a plurality of switching elements connected between the power source lines and the branch line, and
wherein the controller is configured to,
detect a failure in any of the switching elements, and
selecting a path through a different one of the switching elements that avoids a failed one of the switching elements.

14. The vehicular circuit body according to claim 1 ,
wherein the plurality of control boxes includes a second control box configured to be located on a floor of the vehicle when the second control box is mounted to the vehicle,
wherein first control box is configured to be spaced above the floor when the first control box is mounted to the vehicle, and
wherein a front end of the trunk line is connected to a bottom side of the first control box from below when the first and second control boxes are mounted to the vehicle.

15. The vehicular circuit body according to claim 1 ,
wherein each of the power source lines extends through the first control box and extends into a second control box of the plurality of control boxes.
