摘要： A required intake air flow rate is converted to a post-model required intake air flow rate (BMtsm) by a base-system normative model, and the inverse model of an intake system model is used to calculate a base-system required throttle opening degree (BTA) so as to achieve the post-model required intake air flow rate (BMtsm). On the other hand, the required in-take air flow rate (Mt) is converted to a post-model required intake air flow rate (HMtsm) by a high-response-system normative model, and the inverse model of the intake system model is used to calculate a high-response-system required throttle opening degree (HTA) so as to achieve the post-model required intake air flow rate (HMTsm). Then, a target throttle opening degree (TAt) is set so as to fall within the range from the base-system required throttle opening degree (BTA) to the high-response-system required throttle opening degree (HTA) and the reduce a variation amount.

摘要： A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model. The engine inverse model is then used to calculate actuator requirement values for achieving those requirement values. An actuator direct requirement value directly required of each of actuators is also acquired.

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.

摘要： The present invention relates to an air-fuel ratio control device for an internal combustion engine, and makes it possible to maintain high purification performance by suppressing a decrease in the oxygen occlusion capability of a catalyst. When an O2 sensor output oxs is greater than a reference value oxsref, which corresponds to a stoichiometric air-fuel ratio, and smaller than an upper threshold value oxsrefR, a sub-FB reflection coefficient is fixed at a predetermined value vdox2 for providing a lean air-fuel ratio. When, on the other hand, the O2 sensor output oxs is smaller than the reference value oxsref and greater than a lower threshold value oxsrefL, the sub-FB reflection coefficient is fixed at a predetermined value vdox2 for providing a rich air-fuel ratio. The sub-FB reflection coefficient reflects the O2 sensor output oxs in the calculation of a fuel injection amount and increases or decreases to have a consequence on the air-fuel ratio of an exhaust gas.

摘要： The air-fuel-ratio control apparatus for an internal combustion engine obtains a composite air-fuel ratio abyfs from a downstream-side correction value Vafsfb(k) based upon an output value Voxs from a downstream air-fuel-ratio sensor 67 and an output value Vabyfs from an upstream air-fuel-ratio sensor 66, and obtains an upstream-side feedback correction value DFi on the basis of the composite air-fuel ratio abyfs. A fuel injection quantity Fi is determined to a value obtained by adding the upstream-side correction value DFi to a control-use base fuel injection quantity Fbasec (=base fuel injection quantity Fbase·coefficient Ksub). The coefficient Ksub is determined on the basis of the downstream-side feedback correction value Vafsfb(k) in such a manner that the control-use base fuel injection quantity Fbasec (accordingly, the fuel injection quantity Fi) is determined such that the output value Vabyfs from the upstream air-fuel-ratio sensor 66 changes in the direction of canceling the change in the downstream-side feedback correction value Vafsfb(k).
