POWER FEED SYSTEM FOR VEHICLE
First Claim
1. A power feed system for a vehicle provided with a plurality of nodes provided with a load control portion for controlling an electric load disposed at each portion of a vehicle, respectively, a power line for supplying power to each node, and a multiplex transmission line connecting each node to each other, comprising an abnormal current detection portion disposed in a line for receiving power feed from the power line at each node for detecting abnormality of a load current, a detection signal generation portion that starts to receive power when abnormality is detected at the abnormal current detection portion and sends a weak current as an output signal, a diagnostic signal line in common to each node, connected to the detection signal generation portion for transmitting the signal from the detection signal generation portion, and a switching portion for switching the power feed from the power line to the load control portion or the detection signal generation portion.

Abstract
A power feed system for a vehicle provided with a plurality of nodes (4a, 4b, 4c) provided with a load control portion (9) for controlling an electric load disposed at each portion of a vehicle, respectively, a power line (1) for supplying power to each node, and a multiplex transmission line (2) connecting each node to each other, comprising an abnormal current detection portion (5) disposed in a line for receiving power feed from the power line at each node for detecting abnormality of a load current, a detection signal generation portion (10) that starts to receive power when abnormality is detected at the abnormal current detection portion and sends a weak current as an output signal, a diagnostic signal line (3) in common to each node, connected to the detection signal generation portion for transmitting the signal from the detection signal generation portion, and a switching portion (6) for switching the power feed from the power line to the load control portion or the detection signal generation portion.
