The present invention relates to a method for controlling diesel knocking noise and, more specifically, relates to a method for controlling diesel knocking noise, which determines an abnormal state with a diesel knocking noise index. To achieve this, the present invention provides the method for controlling diesel knocking noise, which comprises: an engine combustion step; a DKNI level calculation step of calculating a diesel knocking noise index (DKNI) level; a DKNI difference value calculation step of calculating and comparing a difference value of a DKNI level value calculated in the DKNI level calculation step and a DKNI level target value; a DKNI difference value comparing step of determining whether the difference value is greater than a reference value in the DKNI difference value calculation step; and a pilot fuel amount increase step of increasing a pilot fuel amount by controlling an ECU injection variable when the difference value is greater than the reference value. |
