    Abstract: An apparatus extracts a main waveform component and a branch waveform component from a pressure waveform detected by a fuel pressure sensor. The main waveform component is caused by pressure change traveling in a main passage. The branch waveform component is caused by pressure change traveling in a branch passage. The apparatus calculates traveling speeds based on the components. Then, the apparatus estimates a main passage temperature based on a detected value of the fuel temperature sensor, the traveling speeds, the fuel pressure waveform and an average pressure.

    Abstract: An electronic control unit, in an idle operating state, detects a crankshaft rotation fluctuation in each cylinder using a crank angle sensor, and updates an individual correction value for a control value for each fuel injection valve as a first learned value such that a degree of deviation in the crankshaft rotation fluctuation among the cylinders reduces. The electronic control unit uses a fuel pressure sensor to detect a manner of a fuel pressure fluctuation with fuel injection by each fuel injection valve, and updates an individual correction value for a control value for each fuel injection valve as a second learned value based on a result of comparison between a detected temporal waveform and a basic temporal waveform. In an idle operating state, a learning rate of the second learned value is reduced until the first learned value converges for the first time as compared with after its convergence.

    Abstract: 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.

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.

    Abstract: 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.

    Abstract: A waveform detector detects a variation in fuel pressure based on a detection value of a fuel pressure sensor as a fuel pressure waveform. A determining portion determines whether an interval between injections is zero or smaller than a predetermined value based on the detected fuel pressure waveform when multi-step-injection is performed. A correcting portion corrects an injection command signal indicative of an injection start timing and an injection end timing corresponding to a target injection state in a manner that the interval is increased when the interval is determined to be zero or smaller than the predetermined value.
