ON-VEHICLE POWER DISTRIBUTION DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce power consumption when an ignition signal IG is turned on. SOLUTION: A large-current relay and a small-current relay are connected in parallel, and a diode is connected particularly to the small-current relay in series in a case where both the large-current relay and the small-current relay are turned on when the ignition signal IG stays on. This inhibits power distribution to a small-current relay side by forward voltage of the diode when the ignition signal IG is turned on and the large-current relay and the small-current relay are both turned on. Power consumption when the ignition signal IG is turned on can be reduced in comparison with a conventional measure of connecting a resistor in place of the diode. COPYRIGHT: (C)2005,JPO&NCIPI
