CURRENT OFFSET ADJUSTING METHOD FOR CURRENT SENSOR OF HIGH VOLTAGE BATTERY IN HYBRID VEHICLE

摘要

PURPOSE: A method for correcting current sensor errors of a high voltage battery of a hybrid vehicle is provided to prevent correction logic from acting of the current sensor when a charge and discharge current flows in the high voltage battery. CONSTITUTION: A method for correcting current sensor errors of a high voltage battery of a hybrid vehicle comprises: a step(S101) of deciding whether the vehicle is driving or not; a step(S102) of deciding whether the vehicle is in an idle stop state or not when the vehicle is driving; a step of deciding whether LDC is operating or not; a step(S106) of operating the LDC again after a correction step of the current sensor; and a step of resetting a current value of the current sensor of the high voltage battery in 0 when the vehicle is in the idle stop state.
