    Abstract: A control apparatus and method, and an engine control unit for an internal combustion engine are provided for restraining a torque step and sudden fluctuations in rotation when an air/fuel mixture combustion mode is switched among a plurality of combustion modes, and for improving the fuel economy.

    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.
