摘要： An in-cylinder pressure sensor outputs a signal corresponding to a change rate of an internal cylinder pressure of an engine. The output signal of the in-cylinder pressure sensor is filtered so that frequency components lower than frequencies that substantially compose an internal cylinder pressure required for controlling the engine are cut. The filtered output signal is integrated to determine the internal cylinder pressure. Thus, an internal cylinder pressure having no drift can be determined.

摘要： A controller which is capable of improving the resolution and accuracy of control even when controlling a plant including a control region in which nonlinearities are temporarily very strongly exhibited and a control region in which the nonlinearities are hardly exhibited. A controller 1 which controls fuel pressure Pf of a fuel supply system 10 includes an ECU 2. The ECU 2 sets a target fuel pressure Pf_cmd, calculates a first control input Rsld for causing the fuel pressure Pf to converge to the target fuel pressure Pf_cmd, with equations (1) to (6), modulates the first control input Rsld with equations (11) to (31) to thereby calculate a second control input Udsm, and depending on whether or not during fuel-cut operation or pressure decreasing control, selects one of the first and second control inputs Rsld and Udsm as the control input Upf.

摘要： An apparatus for detecting an in-cylinder pressure of an engine is provided. The apparatus comprises an in-cylinder pressure sensor for outputting a signal indicating a change rate of an in-cylinder pressure and a control unit. The control unit is configured to correct the signal from the in-cylinder pressure sensor, integrate the corrected signal to determine the in-cylinder pressure, determine a change rate of a drift contained in the determined in-cylinder, and feedback the change rate of the drift so that the correction of the signal is made with the change rate of the drift. Since the output of the in-cylinder pressure sensor from which a drift has been removed is integrated, it is prevented that a drift appears in the in-cylinder pressure obtained by the integral. A resetting operation is not required so as to remove a drift.

摘要： A controller which is capable of maintaining stability of a control system even if the dynamic characteristic of a controlled object temporarily changes sharply in the case where a controlled object model is used. An ECU of the controller calculates a first disturbance estimate by carrying out a low-pass filtering process and a rate limiting process on a first estimation error as the difference between a fuel pressure estimate calculated with an estimation algorithm and a fuel pressure. Then, the ECU calculates a second disturbance estimate based on a second estimation error as the difference between the first estimation error and the first disturbance estimate, with a predetermined disturbance estimation algorithm. Further, the ECU calculates a fuel pressure control input based on the fuel pressure and the first and second disturbance estimates, with a predetermined control algorithm.

摘要： A failure detection apparatus for preventing erroneous detection due to a degradation of a sensor and thereby accurately performing failure detection of a variable valve timing and lift control system is provided. The detection apparatus detects a failure of a variable valve timing and lift control system in an engine. The detection apparatus detects a vibration inside an engine cylinder, extracts the component of seating sound of the valve from the output signal of the sensor, determines an actual seating time of said valve from the component of seating sound, and calculates a target seating time of said valve based on at least one of a requested lift amount, a requested advance angle, and a requested open angle depending on the operating conditions. The detecting apparatus corrects the actual seating time for a stationary deviation between the actual seating time and the target seating time caused by degradation or unevenness of the sensor. The detecting apparatus determines a failure of the variable valve timing and lift control system by comparing the corrected actual seating time with the target seating time.

摘要： An ignition timing control system for internal combustion engines, which is capable of preventing occurrence of variation in engine speed and vibrations which can be caused due to variation in combustion state between the cylinders, to thereby improve drivability. The ECU 2 of the ignition timing control system 1 calculates a statistically processed value Pmi_ls#i according to the in-cylinder pressure Pcyl#i, and calculates an averaging target value Piav_cmd by weighted averaging of a minimum value Pmi_ls_min1 and a second minimum value Pmi_ls_min2 within a predetermined range of the statistically processed value. The ECU 2 calculates a correction value DIGCMP#i by performing a limiting process for setting the optimization correction value DIGOP#i for control of the ignition timing to a limit value on the advanced side, on the averaging correction value DIGPIAV#i for causing the statistically processed values Pmi_ls#i to follow the averaging target value Piav_cmd, such that the statistically processed values Pmi_ls#i becomes maximum. The ignition timing IGLOG#i is calculated for each cylinder based on the correction value DIGCMP#i.
