Abstract: A control device for controlling an engine, comprising a variable lift mechanism capable of changing the lift of a valve and a variable compression ratio mechanism capable of changing a compression ratio in a combustion chamber. The control devise controls the variable lift mechanisms and the variable compression ratio mechanism so that, when a requested engine output is increased, a compression ratio decreasing rate is increased over a lift increasing rate and, when the requested engine output is reduced, a lift decreasing rate is increased over a compression ratio increasing rate. When the engine comprises a variable phase mechanism capable of changing the phase of the valve, the control devise controls the variable compression ratio mechanism and the variable phase mechanism so that, when the requested engine output is increased, the compression ratio decreasing rate is increased over the change rate of the phase to a delay angle and, when the requested engine output is reduced, the change rate of the phase to an advance angle is increased over the compression ratio increasing rate. Thus, the contact of the valve with a piston can be avoided.

Abstract: There is provided an intake air amount control system for an internal combustion engine, which controls the amount of intake air by executing both cam phase control and valve lift control, and is capable of enhancing response and accuracy of the intake air amount control, while avoiding interaction between the cam phase control and the valve lift control. In the intake air amount control system 1, an ECU 2 controls the amount of intake air according to a target valve lift Liftin_cmd and a target cam phase Cain_cmd. The Liftin_cmd and Cain_cmd are respectively calculated as the sums of master values Liftin_cmd_ms and Cain_cmd_ms for causing an actual intake air amount Gcyl to converge to a target intake air amount Gcyl_cmd, and slave values Liftin_cmd_sl and Cain_cmd_sl set according to the master values Liftin_cmd_ms and Cain_cmd_ms (steps 56 and 64). In a lift master mode, Cain_cmd_ms is set such that Cain_cmd_ms=0 holds (step 63), and in a phase master mode, Liftin_cmd_ms is set such that Liftin_cmd_ms=0 holds (step 55).

Abstract: A control system for an internal combustion engine, which is capable of reducing exhaust emissions during and after the start of the engine. A control system is capable of changing the valve-closing timing of intake valves relative to the valve-opening timing thereof as desired using a variable intake valve actuation assembly. The control system includes an ECU. The ECU sets a target auxiliary intake cam phase to a start value that sets the valve-closing timing of the intake valves to retarded-closing timing, during starting of the engine, and to a catalyst warmup value that sets the same to timing closer to timing in the Otto cycle operation, during catalyst warmup control after the start of the engine.

Abstract: In a misfire detection system for an internal combustion engine, a product is calculated at every predetermined crank angle by multiplying a value retrieved from a periodic function defined to model torque generation of individual cylinders synchronously with each combustion cycle, by a detected crank angle velocity, and the product is integrated over a predetermined interval to calculate an integral. The integral is then compared with a predetermined value and is detected whether misfire has occurred in one of the individual cylinders, thereby enabling to detect misfire even when misfire occurs successively in a multiple cylinder engine, identify the misfiring cylinders with good accuracy.

Abstract: 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.

The method further comprises the step of filtering the differences with adaptive filters. The method further comprises the step of obtaining a predicted difference of values of the variable to be predicted, through algorithm of estimation with fuzzy reasoning. The method further comprises the step of adding the predicted difference of values of the variable to be predicted, to a current value of the variable to be predicted, to obtain a predicted value of the variable to be predicted.

Abstract: The invention provides a control apparatus comprising a controller for determining a manipulated variable for manipulating a controlled object so that an output of the controlled object converges to a desired value and a modulator for modulating the manipulated variable by using one of a delta-sigma modulation algorithm, a sigma-delta modulation algorithm and a delta modulation algorithm to generate a modulated signal to be applied to the controlled object. The modulator generates the modulated signal so that a center value of an amplitude of the modulated signal follows a change of the manipulated variable. Thus, the modulated signal in which the manipulated variable is reflected without any loss can be generated even when the manipulated variable changes.
