    Abstract: PURPOSE: A knocks control system and a method thereof are provided to improve exhausting performance by setting a targeted value with a predicted knocks generation amount according to driving situation and by controlling discharge of knocks in a direction capable of reducing the discharge of the knocks. CONSTITUTION: A knocks generation amount is predicted by using a virtual sensor. A predicted knocks value is compared with a predetermined knocks target value. The knocks generation amount is controlled so that the predicted knocks value follows the knocks target value(S30). [Reference numerals] (AA) NOx prediction; (BB) Predicted NOx value

    Abstract: PURPOSE: A knocks generation estimation method is provided not to include additional sensor and to estimate the amount of knocks generation in real time through a simple calculation based on fuel amount of a vehicle, the number of engine rotation, an air fuel ratio, and ERG information. CONSTITUTION: A no generation rate is calculated by using an engine combustion pressure and an engine driving variable. The engine combustion pressure is used in order to calculate a no generation period. The no generation rate is calculated from the no generation rate and the no generation period. A NO2 generation amount is calculated from a ratio of NO and NO2 according to an engine driving section and a NO generation amount in order to predict a knocks generation amount.
