Device and method for supplying power to a vehicle, semi-conductor circuit device for use in the same and collective wiring device for a vehicle or an automobile

Abstract

A power supply line is wired in a loop from a battery power supply, and a power supply relay circuit is installed intermediately of the power supply line such that power is supplied from the power supply relay circuit to an electric load connected to a terminal unit of an intensive wiring line. By this arrangement, not only wires for control signals but also wires for power supply can be reduced. The terminal unit may serve also as the power supply relay circuit.

1 . A power supplying apparatus for an automobile, comprising: 
 an anti-lock braking control unit including a control circuit for controlling a solenoid for a hydraulically controlled valve of an anti-lock braking apparatus of said automobile;    a power supply line for connecting said control unit and a power supply of said vehicle to each other; and    an anti-lock braking apparatus power supply circuit for connecting or disconnecting said power supply line connected to said anti-lock braking control unit to or from said solenoid.
