DRIVING MODE IMPLEMENTATION METHOD USING THE COOLING FAN WHICH MINIMIZES SENSITIVE NOISE INCREASE ACCORDING TO THE COOLING FAN ACTIVE RATIO RISING

摘要

PURPOSE: A driving mode implementation method using the cooling fan is provided to deal with eco mode of Power Mode which demand high battery usage ratio compared to normal mode by controlling energy which is used in the cooling fan, in which active ratio is high, to be smaller than high voltage battery output obtained by massive amount of wind, and to satisfy the taste of the driver. ;CONSTITUTION: The driving mode implementation method using the cooling fan includes the steps of: judging the selected driving mode among normal mode, eco mode and power mode in the state of ig on; setting the temperature of high voltage battery, which operates the cooling fan according to the selected driving mode, higher than Tmax set for the normal mode; operating the cooling fan to increase the amount of wind according to the selected driving mode; monitoring if the measured temperature of the high voltage battery, measured by increasing the amount of wind of the cooling fan, exceeds the selected maximum temperature in the normal mode, the eco mode, and power mode; and reducing the engine output to the Tmax if the measured temperature exceeds the maximum temperature set in the normal mode, the eco mode, and the power mode.;COPYRIGHT KIPO 2011
