Abstract: A valve timing control system for an internal combustion engine, which is capable of accurately and delicately controlling an amount of intake air, and thereby maintaining excellent combustion state and reduced exhaust emissions. The valve timing control system variably controls the valve-closing timing of an intake valve with respect to valve-opening timing of the same as desired via a variable intake valve actuation assembly. The ECU of the engine determined a basic value of a target auxiliary intake cam phase according to the demanded drive torque of the engine. The ECU calculates a control input to the variable intake valve actuation assembly such that the cylinder intake air amount converges to a target intake air amount and at the same time the auxiliary intake cam phase is constrained to the basic value of the target auxiliary intake cam phase.

Abstract: A control apparatus which is capable of ensuring both high-level stability and accuracy of control, even when controlling a controlled object having extremal characteristics or a controlled object a controlled object model of which cannot be represented. The control apparatus 1 includes a cooperative controller 30, an onboard model analyzer 40, and a model corrector 60. The model corrector 60 calculates the model correction parameter matrix θ, so as to correct the controlled object model defining the relationship between the intake opening angle θlin and the exhaust reopening angle θrbl and the indicated mean effective pressure Pmi. The onboard model analyzer 40 calculates first and second response indices RI1 and RI2 representative of correlations between θlin, θrbl, and Pmi, based on the controlled object model corrected using θ. The cooperative controller 30 calculates the θlin and θrbl such that Pmi is caused to converge to a target value Pmi_cmd, and determines an increasing/decreasing rate and increasing/decreasing direction of θlin and θrbl according to RI1 and RI2.

Abstract: 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.

Abstract: 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.
