Abstract: A control apparatus is provided for ensuring a high-level control resolution and a high control accuracy even when a plant exhibits strong and varying non-linear characteristics with a varying sensitivity of a control amount to a control input. The control apparatus for controlling a cam phase through a cam phase varying mechanism comprises an ECU. The ECU calculates an SLD control input for controlling a cam phase to converge to a target cam phase in accordance with a predetermined control algorithm, and calculate a control input to the cam phase varying mechanism by modulating the SLD control input in accordance with a predetermined modulation algorithm. The ECU also sets an amplitude setting value in accordance with the cam phase, an engine rotational speed, an oil pressure, and an oil temperature.

Abstract: An in-cylinder pressure sensor outputs a signal corresponding to a change rate of an internal cylinder pressure of an engine. The output signal of the in-cylinder pressure sensor is filtered so that frequency components lower than frequencies that substantially compose an internal cylinder pressure required for controlling the engine are cut. The filtered output signal is integrated to determine the internal cylinder pressure. Thus, an internal cylinder pressure having no drift can be determined.

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.

Abstract: An actuator control system restrains hindrance to an object under control by an interfering substance that exists on its traveling path when the object is moved toward a target position on one axis while the object has been positioned at a target position on the other axis.

The ECU of the control system controls the air-fuel ratio of exhaust gases emitted from the first to fourth cylinders.

Abstract: A control system for an internal combustion engine having at least one control device that affects an air-fuel ratio of an air-fuel mixture to be supplied to the engine, is disclosed. An air-fuel ratio correction coefficient is calculated for correcting an amount of fuel to be supplied to the engine so that the detected air-fuel ratio coincides with a target air-fuel ratio. An air-fuel ratio affecting parameter indicative of a degree of influence that an operation of the control device exercises upon the air-fuel ratio, is calculated. A correlation parameter which defines a correlation between the air-fuel ratio correction coefficient and the air-fuel ratio affecting parameter is calculated using a sequential statistical processing algorithm. A learning correction coefficient relating to a change in characteristics of the control device is calculated using the correlation parameter. The air-fuel ratio is controlled using the air-fuel ratio correction coefficient and the learning correction coefficient.
