  • Patent number: 9771885
    Abstract: A control apparatus for an engine includes a control unit. The engine includes a sensor. The control unit determines whether or not an abnormality has occurred in a calculation function of the control unit on the basis of a comparison result between the control required injection amount and the monitoring required injection amount. The control unit determines whether or not an abnormality has occurred in the calculation function of the control unit without using the comparison result when the comparison result is calculated during a predetermined period. The predetermined period is a period of a delay that occurs between updating of one of respective values of the control rotation speed and the monitoring rotation speed and updating of the other value due to a difference between the first timing and the second timing.

  • Publication number: 20140224227
    Abstract: According to the present invention, torque controllability may be improved in a situation in which there is a gap between a required torque and a current torque based on a supercharge delay of a supercharger when calculation of a target throttle divergence using an air reverse model is applied to a supercharged internal combustion engine. Although the control unit of the present invention usually determines the required torque as a target torque, the control unit determines a value lower than the current torque when a reduction direction change occurs in the required torque while there is the gap between the required torque and the current torque. Desirably, the control unit determines a target torque reduction correspondingly to a decrease in the required torque, and determines a target torque reduction subtracted from the current torque as the target torque.

  • Patent number: 8688357
    Abstract: The present invention relates to a control device for a spark-ignition internal combustion engine provided with a cylinder pressure sensor and aims to facilitate optimal control of a combustion state even in a situation where an operating condition is variable. A predetermined combustion-related parameter whose value is uniquely determined by behavior of a change in cylinder pressure relative to a crank angle is used as a control value. Ignition timing is calculated based on the control value in accordance with a calculation rule determined according to a current or target operating condition of the internal combustion engine. The control value resulting from calculation based on a target value of a predetermined physical quantity relating to torque of the internal combustion engine in accordance with a predetermined calculation rule is used as a base value and is corrected by feeding back an output value of the cylinder pressure sensor.
