摘要： A control apparatus for a motor vehicle is provided in which each of a plurality of output values of the vehicle varies depending upon a plurality of input control parameters for controlling the vehicle. The control apparatus changes the input control parameter or parameters so that each of the output values becomes substantially equal to a corresponding target output value. The control apparatus then determines adapted values of the input control parameters, based on values of the input control parameters obtained when each of the output values becomes substantially equal to the corresponding target output value or falls within a permissible adaptation range of the target output value.

摘要： An EGR control device is provided with an EGR control valve (52) and an electronic control unit (60). An exhaust gas recirculation pipe (51) extends across the EGR control valve (52). The electronic control unit calculates a target EGR ratio, a target air flow rate, an actual EGR ratio, and an actual air flow rate, on the basis of operational state quantities of an engine. The electronic control unit then calculates, as a target converted EGR ratio, a ratio of the target EGR ratio to the target air flow rate, calculates, as an actual converted EGR ratio, a ratio of the actual EGR ratio to the actual air flow rate, and controls an opening of the EGR control valve such that the target converted EGR ratio becomes equal to the actual converted EGR ratio. An actual converted EGR ratio is proportional to an intake-air oxygen concentration, and an actual converted EGR ratio and a target converted EGR ratio are calculated independently of a command injection amount. Therefore, a desired intake-air oxygen concentration is obtained irrespective of flow rate characteristics of injection valves.

摘要： A soot generation amount estimation apparatus obtains a generation speed of a precursor of soot (accordingly, the concentration of the precursor) in consideration of formation of the precursor from fuel, thermal decomposition of the formed precursor, and formation of soot from the formed precursor, and estimates a generation speed of soot (accordingly, the concentration of soot (the generation amount of soot)) in consideration of formation of soot from the precursor, which depends on the concentration of the precursor, and oxidation of the formed soot. The apparatus employs a reaction model in which the reaction process in which soot is generated from fuel is divided into two steps; i.e., a reaction process in which a precursor is generated from fuel and a reaction process in which soot is generated from the precursor. Thus, phenomena, such as a “delay in soot generation” in the reaction process in which soot is generated from fuel, can be accurately simulated.

摘要： This control apparatus obtains a relation (trade-off line) between NOx generation amount and PM generation amount with EGR ratio serving as a parameter from an NOx generation amount estimation model which calculates the NOx generation amount on the basis of the oxygen mole concentration of intake gas and a PM generation amount estimation model which calculates the PM generation amount on the basis of an excess air factor. Further, the control apparatus obtains a straight line (ratio determination line) which passes through a point (appropriate point A) corresponding to a combination of steady-condition appropriate values of the NOx generation amount and the PM generation amount under the present operating conditions and which has a slope K determined in consideration of a regulation value based on a law relating to emission control. The control apparatus uses an intersection (target point B) between the trade-off line and the ratio determination line as an emission target value, and sets an EGR ratio target value Regrt to an EGR ratio corresponding to the target point B.

摘要： The fuel injection control device includes an electronic control unit (ECU) for controlling a fuel injection amount of the diesel engine of an automobile. The ECU determines a basic fuel injection amount in accordance with the engine operating condition such as the amount of depression of the accelerator pedal, the intake air amount and the engine speed. Further, the ECU estimates the magnitude of the torsional vibration of the output shaft system of the engine when the basic fuel injection amount of fuel is supplied to the engine using a model of the output shaft system. The ECU performs a feedforward control based on the estimated magnitude of the torsional vibration and corrects the basic fuel injection amount so that the torsional vibration becomes small. Therefore, the fuel injection amount is corrected to attenuate the torsional vibration before the torsional vibration actually occurs.

摘要： A control apparatus for an internal combustion engine with an exhaust gas recirculation system is disclosed. The control apparatus grasps an optimum relational expression between an excess air ratio and an EGR rate in a transient engine operating condition changing to a certain engine operating condition. Each combination of the excess air ratio and the EGR rate on the relational expression optimizes an amount of generated paticulates and an amount of generated NO.sub.x. The relational expression contains a combination of an optimum excess air ratio and an optimum EGR rate in the certain engine operating condition. The apparatus determines one of a current excess air ratio and a current EGR rate and controls the exhaust gas recirculation system so as to realize the other of an excess air ratio and an EGR rate satisfying the relational expression with respect to one of the current excess air ratio and the current EGR rate.
