Abstract

A power line communication apparatus includes power lines disposed independently and individually, for connecting various loads to a battery by way of fuses, respectively, an inductor disposed at an end portion of each of the above-mentioned power lines on a side connected to the above-mentioned battery, and an information unit for transmitting information by way of each of the above-mentioned power lines.

Claims

1. A power line communication apparatus comprising:

power lines disposed independently and individually, for connecting various loads to a battery by way of fuses, respectively;

an inductor unit disposed at an end portion of each of said power lines on a side connected to said battery; and

an information unit for transmitting information by way of each of said power lines,

wherein the information unit is disposed between one pair of power lines, and a choke coil is disposed between said information unit and a ground.

2. The power line communication apparatus according to claim 1, wherein the information unit is disposed between the power lines and a ground.

3. The power line communication apparatus according to claim 1, wherein a gateway is connected between information unit which are connected to different power lines.

4. The power line communication apparatus according to claim 1, wherein the information unit includes a coding unit for receiving an operation button signal, and for coding said operation button signal, and transmits information from said coding unit to the loads by way of the power lines.

5. The power line communication apparatus according to claim 1, wherein the information unit comprises:

a camera image processing unit for processing an image captured by a camera;

an informing unit for informing the captured image transmitted thereto by way of the power lines from said camera image processing unit; and

an attitude control unit for controlling an attitude of said camera.

6. The power line communication apparatus according to claim 5, wherein the camera is integral with one of a room mirror and a door mirror.

7. The power line communication apparatus according to claim 5, wherein said apparatus comprises:

a first information unit including a head lamp control unit and a head camera control unit;

a second information unit including a tail lamp control unit and a tail camera control unit; and

an information processing unit connected to said first information unit and said second information unit by way of power lines, for transmitting information.

8. The power line communication apparatus according to claim 1, wherein the fuses and the inductor unit are formed integrally.
