  • Patent number: 10338922
    Abstract: A second core calculates an intervening variable that is defined by an inner function, when a time derivative of a state variable is expressed by a function having the state variable, the inner function, and an observable input variable as independent variables. A first core calculates a function by using respective values of the state variable, the intervening variable, and the input variable, and obtains a value of the state variable by time-integration of a value of the function. In the calculation of the function, the value of the state variable calculated in previous time, a value of the intervening variable calculated by the second core in the previous time, and a value of the input variable inputted in this time are used.

  • Patent number: 7032374
    Abstract: An exhaust purification apparatus for an internal combustion engine includes a catalyst unit disposed in an exhaust passage of the engine, upstream and downstream air-fuel-ratio sensors disposed upstream and downstream, respectively, of the catalyst unit, a main-feedback controller, and a sub-feedback controller. The main-feedback controller calculates a main-feedback control quantity on the basis of an output value of the upstream air-fuel-ratio sensor and a predetermined upstream-side target value, and corrects, on the basis of the main-feedback control quantity, the quantity of fuel injected by an fuel injector.

  • Patent number: 6986330
    Abstract: An internal combustion engine has a variable valve actuation device for lifting an intake valve. The device is capable of changing the amount of opening of the intake valve. The device is configured to calculate a first estimated value Gao of the amount of intake air from a parameter regarding the operation state of the engine at the time of opening the intake valve; calculate a second estimated value Gac of the amount of intake air from a parameter regarding the operation state of the engine at the time of closing the intake valve; and calculate an actual amount of intake air Ga based on the first estimated value and the second estimated value.

  • Patent number: 6944508
    Abstract: The present invention is directed to generate an adaptive value in a short time. An adaptive value generating program has an adaptive procedure control program and a DOE tool. The DOE tool is a general statistical processing tool. The adaptive value procedure generating program functions as an interface between a measuring apparatus and the DOE tool. In a data obtaining process, the adaptive value procedure generating program automatically determines a method of selecting a measurement point and passes the result to the DOE tool. Selection of an approximation function and selection of an optimization method are automated. Further, evaluation of a final approximation expression and determination of confirmation data are also automated.
