摘要： A drive control unit that controls an opening and closing operation of the fuel injection valve by causing an excitation current to flow in a solenoid of the fuel injection valve; a current detection circuit that detects the excitation current flowing in the solenoid; and an electronic control unit. The electronic control unit calculates an injection standby period, which is a period from an energization start point of the solenoid to a point at which the fuel injection valve opens, and adjusts an energization period of the solenoid in accordance with the calculated injection standby period. The electronic control unit of the control apparatus for a fuel injection valve then measures a reference fall detection period, which is a period from the energization start point to a reference fall detection point, and sets the injection standby period to be longer as the reference fall detection period is longer. Here, the reference fall detection point is a point at which the excitation current detected by the current detection circuit falls below a reference current value, which is smaller than a peak current value, while the excitation current decreases after reaching the peak current value.

摘要： An engine ECU executes a program including the steps of: detecting a waveform of vibration of an engine at a predetermined knock detection gate (S100); determining whether a detected vibration's waveform and a knock waveform model stored in memory match within a predetermined range; if the model and the detected vibration's waveform match within the predetermined range (YES at S102), determining that the engine knocks (S104); and if the model and the detected vibration's waveform do not match within the predetermined range (NO at S102), then determining that the engine does not knock (S108).

摘要： An engine ECU executes a program including the steps of: detecting a magnitude of vibration of an engine (S 102); detecting a vibration waveform of the engine based on the magnitude (S 104); calculating a correlation coefficient K, in the case where the engine speed NE is smaller than a threshold value NE (1), using the sum of values each determined by subtracting a positive reference value from a magnitude of a knock waveform model, as an area S of the knock waveform model and, calculating the correlation coefficient K, in the case where the engine speed NE is not smaller than the threshold value NE (1), using the area S of the whole knock waveform model (Sl 14); and determining whether or not knocking has occurred using the correlation coefficient K (S 120, S 124). The correlation coefficient K is calculated by dividing by the area S the sum of differences that are each the difference between the magnitude on the vibration waveform and the magnitude on the knock waveform model.

摘要： A drive system for fuel injection valves includes a battery, a capacitor, a drive control unit and an electronic control unit. The electronic control unit is configured to, when an energization start interval (TRPW) between a start of energization of a last one of the fuel injection valves (t21) and a start of energization of a current one of the fuel injection valves (t23) is longer than or equal to a peak reaching time (TRPK) of the last one of the fuel injection valves, extend an energization time (T12) of the current one of the fuel injection valves as the energization start interval (TRPW) reduces. The electronic control unit is configured to, when the energization start interval (TRPW) is shorter than the peak reaching time (TRPK), reduce the energization time (T12) of the current one of the fuel injection valves as the energization start interval (TRPW) reduces.
