Abstract

An optimization method of a power control logic for entering into an idle stop & go (ISG) mode comprises steps of: monitoring a state of charge (SOC) of a battery to detect a parasitic current of thebattery by a battery sensor of a vehicle; transmitting a parasitic current flag to an engine control unit (ECU) when the battery sensor detects the parasitic current; and determining whether a deviceusing standby power of the battery is installed and increasing a voltage of the battery via additional power control when it is determined that the device is installed.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0114354 filed in the Korean Intellectual Property Office on September 6, 2016, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a power supply control logic optimization method and device, more particularly, to a power supply control logic optimization method and device for entering an idle stop&go (ISG) mode. Background technique [0004] In recent years, in response to an increase in oil prices and global warming caused by generation of carbon dioxide, a great deal of research and development has been conducted to improve fuel efficiency in the transportation field. The idle stop and go (ISG) system, which was originally applied to hybrid vehicles, has been widely applied to all types of vehicles, thereby improving fuel efficiency around the world. The ISG sys...
