    • A control apparatus includes a learning portion which learns a control parameter by correcting a learning vector consisting of a plurality of variables and a control parameter based on a measurement vector. The control apparatus further includes an interpolation portion which computes the control parameter corresponding to current variables which represent a current environmental condition by interpolating the control parameter learned by the learning portion. The interpolation portion includes a selecting portion which selects three learning vectors from a plurality of learning vectors, and which computes the control parameter corresponding to the current variables by interpolating the control parameters on a flat surface including the selected three learning vectors.

    • A learning device learns a control parameter (e.g., injection start response delay), which is used for deciding a control content of an injector (controlled object), in relation to a criterion variable (e.g., fuel pressure). The learning device has a storing section for storing a learning vector consisting of the control parameter and the criterion variable. The learning device has a measurement vector obtaining section for obtaining a measurement vector consisting of a measurement value of the control parameter and a measurement value of the criterion variable. The learning device has a correcting section for correcting the learning vector based on the measurement vector and for performing storing and updating of the learning vector in the storing section.

    • A fuel injection detecting device computes a maximum-fuel-injection-rate-reach timing and a fuel-injection-rate-decrease-start timing based on a falling waveform of the fuel pressure and a rising waveform of the fuel pressure. The falling waveform represents the fuel pressure detected by a fuel sensor during a period in which the fuel pressure increases due to a fuel injection rate decrease. The rising waveform represents the fuel pressure detected by the fuel sensor during a period in which the fuel pressure decreases due to a fuel injection rate increase. The rising waveform and the falling waveform are respectively modeled by modeling function. In a case of small fuel injection quantity, an intersection timing at which lines expressed by the modeling functions intersect with each other is defined as the maximum-fuel-injection-rate-reach timing and the fuel-injection-rate-decrease-start timing.
    • 燃料喷射检测装置基于燃料压力的下降波形和燃料压力的上升波形来计算最大燃料喷射速率到达定时和燃料喷射率降低开始正时。 下降波形表示在燃料压力由于燃料喷射速率降低而增加的时段期间由燃料传感器检测到的燃料压力。 上升波形表示燃料传感器在由于燃料喷射率增加而燃料压力降低的时段期间检测到的燃料压力。 上升波形和下降波形分别由建模功能建模。 在小燃料喷射量的情况下,由建模功能表示的线彼此相交的交点定时被定义为最大燃料喷射速率到达定时和燃料喷射速率降低开始定时 。
