    Abstract: Misfire of an engine is detected by extracting a pressure component of combustion from an output of a pressure sensor disposed in a cylinder. An engine misfire detection apparatus obtains a combustion parameter Cr that is a correlation between a reference signal Fc synchronous with the combustion cycle of the engine and cylinder pressure Pc obtained from an output of a pressure sensor disposed in the cylinder. The apparatus detects a misfire of the engine based on the combustion parameter. A misfire can be accurately detected even under a low load condition because the combustion parameter indicating the combustion component is extracted from the cylinder pressure as a correlation between the reference signal synchronous with the combustion cycle of the engine and the cylinder pressure obtained from the sensor output.

    Abstract: A transmission control system is capable of promptly compensating for a disturbance attributable to a mechanical interference that takes place in a selecting operation so as to quickly complete the selecting operation. An adaptation disturbance observer provided in a selection controller calculates a disturbance component term in a model equation of a selecting mechanism for each control cycle of the selection controller. An equivalent control input calculator of a sliding mode controller uses the disturbance component term calculated by the adaptation disturbance observer to calculate an equivalent control input. An adder adds a reaching law input calculated by a reaching law input calculator and the equivalent control input to calculate a control value of a voltage to be applied to a selection motor of the selecting mechanism.

    Abstract: A controller for a transmission capable of preventing an occurrence of a gear squeak caused by a malfunction of a synchronization mechanism. The voltage determination section 24 performs a shift operation of a transmission by determining a control input Vin to a shift motor 13 so as to match an actual position Psc of a coupling sleeve 6 grasped by an actual position grasping section 21 with a target position Psc_cmd of the coupling sleeve 6 set by a target position setting section 22. After starting the shift operation of the transmission, it halts the shift operation by detecting a malfunction in the gear position where the shift operation is under execution when the actual position Psc of the coupling sleeve 6 has reached a malfunction judgment position provided within a range from a balk point to a contact point between the coupling sleeve 6 and an idle gear 7c before a difference Esc between the actual position Psc and the target position Psc_cmd of the coupling sleeve 6 exceeds a given contact judgment value.

    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 target value Vtgt for an output Vout of an O2 sensor 8 (an exhaust gas sensor) disposed downstream of a catalytic converter 4 is set variably depending on a temperature TO2 of an active element 10 of the O2 sensor 8 by a target value setting unit 18, and the air-fuel ratio of an exhaust gas is controlled by an air-fuel ratio control unit 17 to converge the output Vout to the target value Vtgt. An exhaust gas temperature Tgd is estimated by an exhaust temperature observer 19, and the temperature TO2 of the active element 10 is sequentially estimated by an element temperature observer 20 using the estimated value of the exhaust gas temperature Tgd. A heater 13 of the O2 sensor 8 is controlled by a heater controller 22 to keep the temperature TO2 of the active element 10 at a predetermined target value R. The air-fuel ratio is thus controlled to maintain a desired exhaust gas purifying capability of the catalytic converter irrespective of the temperature of the active element of the exhaust gas sensor.
