摘要： A control device for an internal combustion engine that enhances precision of realization of required torque while enhancing emission performance by positively changing an air-fuel ratio. The control device generates a target air-fuel ratio by lessening a change speed of a required air-fuel ratio of an internal combustion engine. However, when the required air-fuel ratio is made rich with return from fuel cut, lessening of the change speed of the required air-fuel ratio is stopped, and the required air-fuel ratio is directly outputted as a target air-fuel ratio. The control device calculates a target air quantity for realizing the required torque under the target air-fuel ratio. The control device manipulates an actuator for air quantity control in accordance with the target air quantity, and manipulates an actuator for fuel injection quantity control in accordance with the target air-fuel ratio.

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： 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.

摘要： An object of this invention is, with respect to a torque-demand-control type controller that subjects two kinds of actuators provided upstream and downstream in an intake passage to coordinated operations based on a requested torque for an internal combustion engine, to enable realization of a pulse-like torque change in a torque decreasing direction that is requested, for example, when performing an upshift operation in an electronically controlled automatic transmission. To achieve this object, according to a controller for an internal combustion engine of this invention, when a pulse component in a torque decreasing direction is included in a requested torque, a second requested torque that does not include the pulse component is generated. In this case, a first actuator provided on the downstream side in the intake passage is operated based on the requested torque. On the other hand, although a second actuator provided on the upstream side in the intake passage is operated based on the requested torque when there is not a valid value of the second requested torque, the second actuator is operated based on the second requested torque when there is a valid value of the second requested torque.

摘要： An object of the present invention, in a vehicle integrated control device, is to cause a request torque having an appropriate magnitude and change speed to be given to an engine control unit from a drive system manager. To this end, according to a vehicle integrated control device according to the present invention, a first maximum torque and a second maximum torque are presented to a drive system manager from an engine control unit. The drive system manager refers to the first maximum torque and the second maximum torque which are presented, and determines a request torque to be given to the engine control unit. The first maximum torque is a maximum torque that can be realized when only an operation amount of a throttle is actively changed without actively changing an operation amount of a wastegate valve. The second maximum torque is a maximum torque that can be realized when both the operation amount of the throttle and the operation amount of the wastegate valve are actively changed.

摘要： 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. The control unit calculates a target air volume from the determined target torque, and calculates the target throttle divergence by using the air reverse model and based on the target air volume.

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 apparatus for a supercharged internal combustion engine, which can achieve a target torque accurately even if the target torque contains a high-frequency vibration component. The control apparatus determines a target air quantity and a target boost pressure from a target torque, operates an actuator for air quantity control according to the target air quantity, and operates an actuator for boost pressure control according to the target boost pressure. The target torque is formed to contain a low-frequency torque component that is set at all times based on a torque requirement from a driver and a high-frequency torque component that is set as necessary for a specific type of vehicle control. When the target torque contains only the low-frequency torque component, the target boost pressure is formed using a pressure component corresponding to the low-frequency torque.
