摘要： A system for discriminating degradation of an exhaust purification system of an internal combustion engine having an adsorbent installed at a bypass exhaust gas passage branched from an exhaust pipe of the engine, which is opened by a switch-over valve at starting of the engine to introduce the exhaust gas such that the adsorbent adsorbs unburned HC in exhaust gas generated by the engine and is closed such that the adsorbent desorbs the adsorbed HC and the desorbed HC is thereafter recirculated at a position upstream of a catalyst. Based on the fact that the HC concentration rising time interval becomes short as the adsorbent degrades and adsorption capacity decrease, the time lapse since engine starting until the detected HC concentration exceeds a predetermined level is measured and is compared with a threshold value such that the adsorbent is discriminated to be degraded if the measured time lapse is less than the threshold value, thereby enabling to improve the discrimination accurately.

摘要： An apparatus for controlling an internal combustion engine has an amount-of-intake-air control unit for generating a command value for the opening of a flow control valve in an intake passage of the engine, which emits exhaust gases through a catalytic converter, so as to increase an amount of intake air introduced into a combustion chamber by a predetermined quantity greater when the engine operates in an idling mode after it has started to operate than when the engine operates in a normal idling mode, and controlling the opening of the flow control valve based on the generated command value, and an ignition timing control unit for controlling the ignition timing according to a feedback control process to correct the ignition timing so as to be retarded in order to converge the rotational speed of the engine to a predetermined target rotational speed while the amount of intake air is being increased. The amount-of-intake-air control unit successively acquires amount-of-heat data representing the amount of heat energy actually given to the catalytic converter by exhaust gases flowing into said catalytic converter while the amount of intake air is being increased, and corrects the command value for the opening of said flow control valve according to a feedback control process in order to converge the acquired amount-of-heat data to a predetermined target value representing an amount of heat energy to be given to said catalytic converter.

摘要： A control system for a plant includes a sensor for detecting an output from the plant, an adaptive controller for controlling a manipulated variable applied to control of the plant in such a manner that an output from the sensor becomes equal to a desired value, and an adaptive parameter-adjusting device for adjusting adaptive parameters used by the adaptive controller. The adaptive parameter-adjusting device has an identification error-calculating device for calculating an identification error of the adaptive parameters and generating an identification error signal indicative of the calculated identification error, and an adjusting device for adjusting the adaptive parameters based on the calculated identification error. The adaptive parameter-adjusting device includes a non-linear filter for generating an output of 0 or approximately 0 in response to the identification error signal when the identification error is within a predetermined range. The adjusting device adjusts the adaptive parameters by using the output from the non-linear filter.

摘要： A control system for controlling an internal combustion engine which discharge exhaust gases through an emission purifier includes a controller which increases the quantity of intake air drawn into the internal combustion engine while the internal combustion engine is idling after the internal combustion engine has started to operate, to a level which is greater by a predetermined increase than the quantity of intake air drawn into the internal combustion engine while the internal combustion engine is idling normally. The controller also generates a command value for ignition timing of the internal combustion engine according to a feedback control process to converge the rotational speed of the internal combustion engine toward a predetermined target rotational speed, and controlling the ignition timing of the internal combustion engine based on the generated command value thereby to retard the ignition timing. The controller establishes the target rotational speed by changing the target rotational speed from a preset rotational speed toward a predetermined idling speed after the rotational speed of the internal combustion engine has reached the preset rotational speed which is higher than the idling speed after the quantity of intake air drawn into the internal combustion engine has started being increased.

摘要： In a control system for controlling a gear ratio of a multi-step geared or continuously variable automatic transmission, the driver's intention to decelerate is inferred by carrying out a first fuzzy reasoning using a degree of throttle opening or the like and then the target gear ratio is determined by carrying out a second fuzzy reasoning using parameters including the inferred driver's intention to decelerate. The first fuzzy reasoning is carried out using fuzzy production rules classified by operating conditions such as a road profile and a vehicle speed. The inferred driver's intention to decelerate is canceled if braking is discontinued. Thus the control ascertain the intention of the driver and is thus possible to achieve sophisticated shift scheduling well matched to the sensibilities of the driver.
