摘要： The air-fuel-ratio control apparatus for an internal combustion engine obtains an upstream-side feedback correction value DFi for feedback-controlling an air-fuel ratio on the basis of a value (Fcrlow(k−N)) that is obtained by performing a low-pass filter process with a time constant τ to a value corresponding to an upstream-side target air-fuel ratio abyfr at the time point a dead time, which corresponds to the period from a time when the instruction for injecting fuel to the time when exhaust gas generated based up on a combustion of the fuel reaches an upstream air-fuel-ratio sensor 66, before the present point in time, and a value (Fc(k−N)) corresponding to an output value Vabyfs from the upstream air-fuel-ratio sensor 66 at the present time. The time constant τ of the low-pass filter process is set to a value equal to the time constant of the response delay of the upstream air-fuel-ratio sensor 66.

摘要： The output from an air-fuel ratio sensor is corrected using an integral term that is calculated by integrating values of deviation of the output from an oxygen sensor with respect to a reference output that would be obtained when the combustion air-fuel ratio is stoichiometric, when an engine operates with a target combustion air-fuel ratio set to the stoichiometric air-fuel ratio. A fuel-cutoff prohibition period in which fuel supply cutoff is prohibited is set so that the engine continues to operate with the target combustion air-fuel ratio set to the stoichiometric air-fuel ratio, until the integral term is updated at least once. The integral term may be updated when a predetermined updating condition is satisfied.

摘要： In a device and a method for performing a switching control to a standby system in a hybrid system including a duplex system and a backup line, communication is performed without using a backup line when a line is switched in an exchange. The device includes a first exchange having a pair of communication multiplexers and a communication line management processor. The backup line uses a public network. A second exchange is provided for interchanging between a line connected via the first exchange and the backup line using the public network. A normal notification signal is transmitted to the opposite communication party or second exchange when one of the communication multiplexers is switched to the standby system. A regulation releasing signal is transmitted after the switching operation so that communication is performed without using the backup line.

摘要： A vehicle control apparatus that inhibits fuel efficiency from being aggravated as a result of ignition timing of the internal combustion engine being retarded. The vehicle control apparatus includes a drive system control unit and an engine control unit. The engine control unit adjusts an amount of intake air based on the demanded torque and adjusts ignition timing so as to compensate for any deviation between torque achievable through an adjustment of the amount of intake air and the demanded torque. The drive system control unit calculates desirable torque to be desirably output to the internal combustion engine for achieving a target operating state of the vehicle, and limits a change rate of the desirable torque by using a predetermined guard value determined from torque adjustment capacity of the internal combustion engine and outputs the desirable torque after the limiting as the demanded torque to the engine control unit.

摘要： The present invention relates to a control device for a spark-ignition internal combustion engine provided with a cylinder pressure sensor and aims to facilitate optimal control of a combustion state even in a situation where an operating condition is variable.A predetermined combustion-related parameter whose value is uniquely determined by behavior of a change in cylinder pressure relative to a crank angle is used as a control value. Ignition timing is calculated based on the control value in accordance with a calculation rule determined according to a current or target operating condition of the internal combustion engine. The control value resulting from calculation based on a target value of a predetermined physical quantity relating to torque of the internal combustion engine in accordance with a predetermined calculation rule is used as a base value and is corrected by feeding back an output value of the cylinder pressure sensor.

摘要： A control device for an internal combustion engine is provided. The control device includes means which controls fuel injection by a fuel injection device, and means which controls the throttle. The fuel injection control means sequentially restarts fuel injection for each cylinder in accordance with an ignition sequence among cylinders when cancellation conditions of fuel cut are satisfied during implementation of the fuel cut. Meanwhile, the throttle control means firstly controls the throttle to a closing side when the cancellation conditions of fuel cut are satisfied. The throttle is controlled to the closing side, whereby the air amount in the intake pipe is decreased, and the air amount in a cylinder which is the basis of calculation of a fuel injection amount is also decreased.

摘要： An air-fuel ratio control device includes an air-fuel ratio sensor provided upstream from a three-way catalyst, and an oxygen sensor provided downstream from the three-way catalyst. The air-fuel ratio control device controls the fuel supply amount based on the output from the air-fuel ratio sensor, and compensates for errors in the air-fuel ratio sensor by correcting the fuel supply amount based on the output from the oxygen sensor. The fuel supply correction amount is calculated based on an integral term that integrates the deviation between the output from the downstream air-fuel ratio sensor and the target air-fuel ratio. When a fuel supply adjustment control is executed, the value of the integral term in the sub-feedback control is not updated for a predetermined period after the fuel supply adjustment control ends. The actual air-fuel ratio is thus brought to the target air-fuel ratio in an appropriate manner.

摘要： In a control device which uses a specific physical quantity as a control variable of an internal combustion engine, and controls the internal combustion engine by manipulation of one or a plurality of actuators, switching of setting of a manipulation variable based on a required value of a physical quantity and setting of the manipulation variables by direct instruction to individual actuators is performed without generating discontinuity in a realized value of the physical quantity. When a manipulation variable instruction value directly designating a manipulation variable of an actuator is present, the manipulation variable instruction value is converted into a value of a physical quantity which is realized in the internal combustion engine by the operation quantity instruction value. When a deviation between a physical quantity conversion value converted from the manipulation variable instruction value and the physical quantity required value is within a predetermined range, switch of information for use in setting of the manipulation variable of each of the actuators is permitted.
