Abstract
A system for controlling a high-voltage relay of an eco-friendly vehicle includes a high-voltage battery, a plurality of driving devices driven with power supplied from the high-voltage battery, a relay unit including the high-voltage relay and a relay coil, the high-voltage relay being driven based on an amount of current flowing through the relay coil to interconnect the high-voltage battery and the driving devices, a load determiner for determining whether a conduction current load of the high-voltage relay is high or low, and a controller for changing the amount of current flowing through the relay coil based on a result of the determination of the load determiner.
