Abstract: A combustion state parameter calculation method for an internal combustion engine, which is capable of continuously calculating a combustion state parameter while properly maintaining the accuracy of the calculated parameter even when part of in-cylinder pressure sensors is in failure. In the combustion state parameter calculation method, as a combustion state parameter, a first combustion state parameter dependent on the magnitude of in-cylinder pressure is calculated based on a detection value from an in-cylinder pressure sensor, on a cylinder-by-cylinder basis. When it is determined that a characteristic abnormality failure in which the magnitude of the detection value deviates from the actual in-cylinder pressure has occurred in part of the in-cylinder pressure sensors and has not occurred in the other in-cylinder pressure sensors, the first combustion state parameter of a failure-determined cylinder is calculated based on the detection value from the other in-cylinder pressure sensors.

Abstract: A control device for an internal combustion engine can correct precisely a detection result of an in-cylinder pressure sensor which may generate a detection error in a temperature changing process, to control the operation with a smaller error. The control device includes: an operational parameter calculating section that calculates an operational parameter related to control of the engine based on the sensor signal from the sensor; a sensor temperature estimating section that estimates a current temperature change amount of the sensor based on an operating state of the engine; a storage section which stores a correction amount map indicating a correction amount for an operational parameter in accordance with a temperature change amount of the sensor; and an operational parameter output section that corrects the calculated operational parameter with reference to the correction amount map based on the estimated temperature change amount of the sensor, to output the corrected operational parameter.

Abstract: An engine torque estimator for an internal combustion engine, includes a cylinder internal pressure sensor, an indicated-torque calculator, a pump loss torque calculator, and an engine torque calculator. The cylinder internal pressure sensor detects a cylinder internal pressure in a cylinder. The indicated-torque calculator calculates an indicated torque in a second combustion cycle based on the cylinder internal pressure detected in a period from an exhaust stroke in a first combustion cycle to an expansion stroke in the second combustion cycle. The second combustion cycle that follows the first combustion cycle. The pump loss torque calculator calculates a pump loss torque in the second combustion cycle based on the cylinder internal pressure detected in the period. The engine torque calculator calculates an engine torque of the internal combustion based on the indicated torque and the pump loss torque.

Abstract: A control device for an internal combustion engine includes an in-cylinder pressure detector, an output shaft torque calculator, a target torque calculator, an input torque parameter calculator, and a controller. The output shaft torque calculator is to calculate an output shaft torque of an output shaft of the internal combustion engine based on an in-cylinder pressure. The target torque calculator is to calculate a target torque of the output shaft torque. The input torque parameter calculator is to calculate an input torque parameter representing an input torque such that the output shaft torque becomes equal to the target torque using a feedback control algorithm which is based on a controlled object model which models a controlled object that receives the input torque parameter as input and produces the output shaft torque as output. The controller is to control the output shaft torque using the input torque parameter.
