摘要： A control device for a spark-ignition internal combustion engine that sets ignition timing based on a target value of a predetermined combustion-related parameter correlated with a combustion state and operates an ignition device in accordance with the ignition timing thus set. The control device calculates an actual value of the combustion-related parameter from an output value of the cylinder pressure sensor and feeds back the calculated value of the combustion-related parameter to the setting of ignition timing. Further, in parallel with the above processing, the control device calculates a value of a predetermined combustion variation parameter correlated with the magnitude of combustion variation from the output value of the cylinder pressure sensor. If the calculated value of the combustion variation parameter deviates from an allowable range of the combustion variation, the control device stops the feedback of the calculated value of the combustion-related parameter.

摘要： A control device for an internal combustion engine is provided. The control device includes means which controls fuel injection by a fuel injection device, and means which controls the throttle. The fuel injection control means sequentially restarts fuel injection for each cylinder in accordance with an ignition sequence among cylinders when cancellation conditions of fuel cut are satisfied during implementation of the fuel cut. Meanwhile, the throttle control means firstly controls the throttle to a closing side when the cancellation conditions of fuel cut are satisfied. The throttle is controlled to the closing side, whereby the air amount in the intake pipe is decreased, and the air amount in a cylinder which is the basis of calculation of a fuel injection amount is also decreased.

摘要： In a vehicle control apparatus controlling a vehicle operating state by using a torque generated by an internal combustion engine, an arrangement is made to inhibit fuel efficiency from being aggravated as a result of ignition timing of the internal combustion engine being retarded.The vehicle control apparatus includes a drive system control unit that comprehensively controls a drive system of the vehicle and an engine control unit that controls the internal combustion engine based on demanded torque issued from the drive system control unit. The engine control unit adjusts an amount of intake air based on the demanded torque and adjusts ignition timing so as to compensate for any deviation between torque achievable through an adjustment of the amount of intake air and the demanded torque. The drive system control unit calculates desirable torque to be desirably output to the internal combustion engine for achieving a target operating state of the vehicle based on an accelerator operation amount by a driver or signals from various types of sensors mounted on the vehicle. The drive system control unit limits a change rate of the desirable torque by using a predetermined guard value determined from torque adjustment capacity of the internal combustion engine and outputs the desirable torque after the limiting as the demanded torque to the engine control unit. The guard value is set with reference to a range of the change rate of torque achievable through the adjustment of the amount of intake air in the internal combustion engine.
