摘要： PROBLEM TO BE SOLVED: To automatically perform a knocking determination corresponding to the sense of hearing of the human ear without depending on the sense of hearing. SOLUTION: A cylinder pressure sensor 14 is placed on an engine, and a microphone detecting a sound that is generated during engine operation is placed with an appropriate gap from the engine. A waveform (search waveform) of an output signal of the sensor 14 and a waveform (observation waveform) of an output signal of the microphone 11 are calculated for sum of products to calculate a correlation value of the both output signals. Since this correlation value and the knocking strength by the sense of hearing have almost a linear relationship, if the value is used as a measurement value of the knocking strength, the measurement value of the knocking strength is associated with the knocking strength by the sense of hearing, eliminating a person to hear and distinguish the knocking sound in an adapting step for the ignition timing.

摘要翻译：要解决的问题：自动执行与人耳听觉相对应的敲击判定，而不依赖于听觉。解决方案：气缸压力传感器14被放置在发动机上，并且在发动机操作期间产生的声音的麦克风被放置有与发动机适当的间隙。计算传感器14的输出信号的波形（搜索波形）和麦克风11的输出信号的波形（观察波形），以产生两个输出信号的相关值。由于该相关值和通过听觉的敲击强度几乎具有线性关系，因此如果将该值用作爆震强度的测量值，则敲击强度的测量值与敲击强度相关联听觉，消除一个人在点火正时的适应步骤中听到和区分敲击声。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To solve the problem that when required torque is reduced, actual VCT is shifted to a timing advance side with respect to a VCT target value and a combustion state is deteriorated as a result, due to response delay of a valve timing variable device capable of varying a relative rotating phase difference (VCT) of a cam shaft 42 with respect to a crank shaft 28 of a gasoline engine 10. SOLUTION: When the required torque of the gasoline engine 10 is reduced, a combustion state achieved by the VCT target value obtained by a map operation is estimated. When the combustion state is not within a tolerance, feed forward correction of operation amount of an actuator used for output control of the gasoline engine 10 is performed, such as setting of the VCT target value to the timing delay side from the value obtained by the map operation.

摘要： PROBLEM TO BE SOLVED: To efficiently adapt a map constant of a plurality of engine control parameters within a comparatively short period of time.
SOLUTION: The map constant of a plurality of the engine control parameters is adapted by using genetic algorism within a comparatively short period of time. A new group is formed by forming a specified number of new individuals partial genes of which are changed by making LSB of the control parameters (changing width) the genes, applying one data of the control parameters to one genetic type, regarding combination of data (genetic type) of a plurality of the control parameters to be an adaptive object as one of the individuals, forming an initial group by forming a specified number of the individuals under a proper method at first, leaving only the individuals high in adaptability in following generation by selecting them from the group, and crossing and mutating the individuals in this genetic algorism. Thereafter, the optimum value is found by making the above estimation, selection, crossing, mutation and group formation the one generation and repeating them in a proper number of the generations.

摘要： PROBLEM TO BE SOLVED: To estimate a misfire region in an adapting process of an engine control parameter.
SOLUTION: A relation between the engine control parameter and an ignition delay/combustion duration and a relation between the ignition delay/combustion duration and combustion stability are modeled based on measurement data of an engine characteristic to provide a misfire estimating model, and a misfire region is estimated using the misfire estimating model. When the misfire region can be thus estimated using the misfire estimating model, measuring points are arranged only in a combustible region except for the estimated misfire region, the engine characteristic is measured, and an engine characteristic model is prepared based on the measurement data. When the engine characteristic model satisfies a required accuracy, the control parameter is adapted using the engine characteristic model.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of suitably controlling output characteristics of the internal combustion engine irrespective of aging of an actuator adjusting flow rate of gas in the internal combustion engine.
SOLUTION: An actual VCT is estimated based on change of a target value of operation quantity of a variable valve timing device (VCT target value) (step S12). It is judged based on difference between the actual VCT and the estimation value whether dynamic characteristics of the variable device changes or not (step S16). When it is judged that the same changes, change of VCT dynamic characteristics is reflected to a model (step S20). Then, VCT target value map is re-adapted by simulating a condition of a gasoline engine when VCT target value is variously changed based on the model having the change reflected thereon.

摘要： PROBLEM TO BE SOLVED: To improve detecting accuracy of throttle opening by compensating an output change caused by a temperature change in a throttle opening sensor during the operation of an engine. SOLUTION: Throttle opening is temporarily stopped to opener regulation opening by tension of a valve return spring 41 of an opener mechanism 47 by temporarily turning off a motor 17 each time a specified learning execution condition is established during the operation of an engine, an output value of a throttle opening sensor 18 is learnt as the opener regulation opening, and a learning value of the reference position (for example, the full closed position) is updated on the basis of the learnt value of the opener regulation opening. In learning of the opener regulation opening, since the motor 17 is turned off to temporarily stop the throttle opening to the opener regulation opening, the opener regulation opening may be learnt in an operating condition in which drivability and exhaust emission are not deteriorated (for example, in fuel cutting in slow accelerating or decelerating at the vicinity of the opener regulation opening).

摘要： PROBLEM TO BE SOLVED: To provide a controller for a brake booster and a recording medium capable of ensuring the negative pressure of the constant pressure chamber of the brake booster without causing a problem such as an engine stall upon start at low temperature or when the load of an engine such as an air conditioner is large. SOLUTION: In step 120, an ordinary ISC controlled variable DISC is calculated. In step 130, the negative pressure of an engine is low, so that a booster negative pressure deciding process is carried out to decide whether or not the negative pressure of a booster is low. In step 140, in order to increase or decrease the quantity of intake air, a DISC correction process is carried out for correcting the ISC controlled variable DISC. In step 150, a process is performed for outputting the ISC controlled variable DISC corrected by the DISC correction process. The opening and closing state of an ISC valve 19 is adjusted corresponding to the output value of the ISC controlled variable DISC to control the increase or decrease of the quantity of auxiliary air.
