Abstract: A device and a method for determining the trouble of a cylinder pressure sensor. The device accurately detecting the trouble of the cylinder sensor without increasing cost calculates the cylinder pressure of an internal combustion engine based on an output from the cylinder sensor installed in the internal combustion engine and calculates a drift parameter indicating the drift amount of the cylinder pressure based on the cylinder pressure. When the drift parameter is not within a specified range, the device determines that the cylinder pressure sensor is defective. According to one embodiment, the specified range can be set based on the behavior of the cylinder pressure. According to the other embodiment, a correction factor is obtained according to the operating state of the internal combustion engine, and the drift parameter is corrected with the correction factor. Also, according to the third embodiment, the cylinder pressure sensor is operated so that a specified search signal is superimposed on the output from the cylinder pressure sensor. The cylinder pressure is calculated based on the output from the cylinder pressure sensor on which the search signal was superimposed.

Abstract: A control for a modeled plant is provided. The modeled plant is represented by a model expression that is based on an input into the plant, an output from the plant, model parameters, and an estimated value for disturbance that is applied to the plant. The model expression includes a term in which the estimated disturbance value is multiplied by at least one of the model parameters. The model parameters are identified. The estimated disturbance value is calculated so that an error between a model output that is calculated based on the model expression and an actual output of the plant is minimized. The input into the plant is calculated based on the model expression so as to control the plant. Thus, the estimated disturbance value is directly reflected in the input into the plant without being calculated by any of the model parameters.

Abstract: A plant control includes determining a control input into the plant to cause a control output of the plant to converge to a desired value. A value of at least one parameter for adjusting a speed of change of the control output relative to change of the desired value is determined in accordance with a plant condition. The control input is determined based on the parameter having the value thus determined. The parameter includes a first parameter for changing a speed of change of the control input relative to change of the desired value. The parameter can also include a second parameter for changing the relative speed via a corrected desired value that is determined by correcting the desired value. The second parameter can further include a gradient parameter and a gradually-approaching characteristic parameter.

Abstract: A plant control system using response specifying control that makes it possible to independently set a follow-up behavior for an output value of a plant when a target output value of the plant changes and a convergent behavior for a difference between a target output value and an output value when the output value of the plant changes. The control system has a controller for determining a clutch stroke on the basis of a model equation of a clutch device such that a target rotational speed and an actual rotational speed of the clutch device coincide with each other. The controller includes a target value filter for carrying out filtering computation on a target rotational speed to calculate a filtering target value that converges to the target rotational speed with a response delay, and a response specifying control unit that determines the clutch stroke by response specifying control such that the filtering target value and the clutch rotational speed coincide with each other.

Abstract: A method of controlling ignition timing of an engine. In the control method, final ignition timing for performing ignition is calculated by adding a variation component to a set ignition timing. According to the final ignition timing, an indicated average effective pressure of an in-cylinder pressure detected when ignition is performed is calculated. An ignition timing characteristic curve indicating the correlation between the indicated average effective pressure and the variation component is estimated and optimal ignition timing is calculated from the characteristic curve. Feedback control for converging the set ignition timing to the optimal ignition timing is then performed. Consequently, the ignition timing is controlled to an optimal ignition timing corresponding to a current operational state of the engine.

Abstract: A transmission comprises a first transmission mechanism and a second transmission mechanism. When a clutch is in an engaged state, the first transmission mechanism transmits a driving force from the engine to the axle shaft. When a clutch is in a disengaged state, the second transmission mechanism transmits a driving force from the engine to the axle shaft. An electromagnetic brake is connected to the second transmission mechanism. A braking force generated by the electromagnetic brake allows the transmission of a driving force by the second transmission mechanism. Thus, a driving force is continuously provided even when the clutch is released for a gear change operation.
