摘要： Disclosed is a control device that is used for an internal combustion engine and capable of making various requests concerning the performance of the internal combustion engine be reflected in a target control amount value while the requests need not be expressed in the form of a requested control amount value. The control device acquires various requests concerning the performance of the internal combustion engine and sets a request-specific constraint on a control amount value. More specifically, the control device expresses constraints to be set for control amount values as a set of constraint index values assigned to individual control amount values, and varies the distribution of the constraint index values assigned to the control amount values in accordance with the type of a request. Next, the control device integrates, for each control amount value, the constraint index values assigned to individual requests with respect to each control amount value. Then, in accordance with the distribution of the integrated constraint index value for a control amount, the control device determines a limitation of the control amount, which is defined by an upper-limit value and a lower-limit value. The control device determines a target control amount value within the determined limitation.

摘要： A control device for an internal combustion engine provided by the present invention is a control device which can satisfy both a requirement relating to exhaust gas performance of the internal combustion engine and a requirement relating to operation performance by properly regulating a change speed of a required air-fuel ratio, in the internal combustion engine which uses torque and an air-fuel ratio as control variables. The control device receives the requirement relating to the exhaust gas performance of the internal combustion engine, and calculates an air-fuel ratio which satisfies the requirement as a required air-fuel ratio. When a predetermined reduction condition is not satisfied, an original required air-fuel ratio is directly determined as a final required air-fuel ratio. However, when the reduction condition is satisfied, the change speed is reduced by processing the signal of the original required air-fuel ratio, and determines the required air-fuel ratio with the change speed reduced as the final required air-fuel ration. The reduction condition includes a condition that the change amount of the original required air-fuel ratio, in more detail, a change amount per calculation period is larger than a predetermined air-fuel ratio change determination value.

摘要： A control device for an internal combustion engine provided by the present invention is a control device which can satisfy a requirement concerning exhaust gas performance of the internal combustion engine, a requirement concerning fuel economy performance, and a requirement concerning operation performance with an excellent balance by properly regulating a change speed of a required air-fuel ratio and an ignition timing. The present control device keeps the ignition timing at an optimal ignition timing if a predetermined permission condition is not satisfied. However, when the permission condition is satisfied, the present control device controls the ignition timing so as to compensate for a difference which occurs between torque which is estimated from an operation of an actuator for air quantity control and required torque by the ignition timing. Further, if a predetermined lessening condition is not satisfied, the present control device determines an original required air-fuel ratio directly as a final required air-fuel ratio. However, if the lessening condition is satisfied, the present control device processes a signal of the original required air-fuel ratio to lessen a change speed thereof, and determines a required air-fuel ratio the change speed of which is lessened as a final required air-fuel ratio. The permission condition includes the required air-fuel ratio changing in a rich direction, and a change amount thereof being larger than a predetermined determination reference value, and the lessening condition includes the change amount of the required air-fuel ratio being larger than a determination reference value, and the permission condition being unsatisfied.

摘要： A control device is provided that generates a target air-fuel ratio by lessening a change speed of a required air-fuel ratio of an internal combustion engine. However, when a deterioration degree of a catalyst which is disposed in an exhaust passage of the internal combustion engine is a predetermined reference or more, lessening of the change speed of the required air-fuel ratio is stopped, or a lessening degree of the change speed of the required air-fuel ratio is decreased. The control device calculates a target air quantity for realizing the required torque under the target air-fuel ratio. For calculation of the target air quantity, data in which relationship of torque generated by the internal combustion engine and an air quantity taken into a cylinder is fixed by being related to an air-fuel ratio can be used.

摘要： A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.

摘要： In a control of an internal combustion engine control apparatus, the control apparatus includes: a fuel tank that stores a fuel; a vaporized fuel tank that is connected to an intermediate portion of an intake passageway of an internal combustion engine and that stores a vaporized fuel that is formed by vaporization of the fuel; an in-tank fuel supply device that supplies the fuel from the fuel tank into the vaporized fuel tank; and a normally-closed vaporized fuel supply valve that opens and closes a connecting portion between the vaporized fuel tank and the intake passageway. The control apparatus estimates air/fuel ratio in the vaporized fuel tank, and produces the vaporized fuel in the vaporized fuel tank by driving the in-tank fuel supply device, with the vaporized fuel supply valve closed, until the estimated air/fuel ratio becomes substantially zero, during operation of the engine. At the time of starting the engine, the control apparatus supplies the vaporized fuel stored in the vaporized fuel tank into the intake passageway by opening the vaporized fuel supply valve.
