Abstract: An operation status value detection unit detects two or more operation status values indicating an operation status of an internal combustion engine. A filtering processing unit applies filtering processing to the detected operation status values, and an operation status value difference calculation unit calculates the difference between the filter-processed operation status value and the corresponding non-filter-processed operation status value so as to calculate two or more operation status value differences. An operation status value difference normalization unit normalizes the two or more operation status value differences, based on predetermined reference values for the two or more operation status values, so as to calculate two or more normalized operation status value differences; and a transient correction unit corrects a control amount for controlling output of the internal combustion engine, based thereon, when the engine is in a transient-operation mode.

Abstract: A knock control device is provided in which erroneous knock detection can be reduced by suppressing sudden knock signal changes due to noise, without causing any increase in the number of matching steps, deterioration in the S/N in knock detection and decrease in detection performing frequency. In the knock control device, an open gain is applied to the detected signal only during a knock detection window set in advance by a knock window setting means. The window corresponds to a period in which vibration due to knock arises. During other periods, either a closed gain or an interpolated gain value is applied to the detected signal.

Abstract: A state of an oil pressure is determined based on combination of activation of an oil pressure switch and information of the temperature detected by a temperature sensor and an engine speed detected by an engine speed sensor such that determination of the oil-pressure state is conducted from a lower engine-speed range in a case in which the temperature detected by the temperature sensor is relatively low, compared with a case in which the temperature detected by the temperature sensor is relatively high. Accordingly, the oil-pressure state can be properly determined not only in a high engine-speed range but in a low engine-speed range, by utilizing the simple oil pressure switch activated to the conductive state in response to the oil pressure.
