Abstract

An electrical wiring device for vehicle includes a distribution module that is disposed between an auxiliary connector and optional devices. The distribution module includes: semiconductor relays connected to a power supply line; input/output interfaces; a control unit configured to control the semiconductor relays and the input/output interfaces on the basis of various kinds of signals acquired via a communication line; and a connecting terminal for connecting outputs of the semiconductor relays and outputs of the input/output interfaces to the optional devices. The control unit controls operations of the semiconductor relays and the input/output interfaces corresponding to the optional devices connected to the connecting terminal.

First claim

What is claimed is:

1 . An electrical wiring device for vehicle, comprising:
an auxiliary connector to which a power supply line, a ground line, and a communication line for an in-vehicle network all mounted on a vehicle are connected; and a distribution module disposed between optional devices mounted on the vehicle and the auxiliary connector, the distribution module comprising: one or more relays connected to the power supply line; one or more input/output interfaces; a control unit configured to control the relays and the input/output interfaces on the basis of various kinds of signals acquired via the communication line; a connecting terminal for connecting outputs of the relays and outputs of the input/output interfaces to the optional devices; and a fuse function for detecting an overcurrent on the basis of an electricity energizing current and an electricity energizing time of each of the relays, wherein the control unit is configured to control operations of the relays and the input/output interfaces corresponding to the optional devices connected to the connecting terminal.

2 . The electrical wiring device for vehicle of claim 1 , wherein
the control unit is configured to switch ON and OFF of each of the relays corresponding to vehicular signals acquired via the communication line.

3 . The electrical wiring device for vehicle of claim 1 , wherein
the distribution module includes a voltage converter for converting a voltage supplied from the power supply line.
