摘要： A control device according to the present invention includes a plurality of arithmetic units that operate in parallel. A sensor value of the control amount is input to the first arithmetic unit in a signal transmission sequence, and a correction amount for the manipulation amount is output from the last arithmetic unit in the signal transmission sequence. The first arithmetic unit has a controller that produces an output by processing the input sensor value, and the arithmetic units other than the first arithmetic unit has a delay element that delays an input by a predetermined number of steps and a controller that produces an output by processing the delayed input.

摘要： It is a task of the invention to make it possible to calculate a control target value of one actuator or control target values of a plurality of actuators regarding engine control at a high speed through the use of a multicore processor. With a view to accomplishing this task, a plurality of lattice points that are arranged on a two-dimensional orthogonal coordinate system having axes representing a first operating condition and a second operating condition respectively are associated respectively with at least one or some of a plurality of cores that are arranged in a latticed manner on the multicore processor on one-on-one level on a same line as on the two-dimensional orthogonal coordinate system, and a calculation program for calculating an optimal control value at the associated lattice point or calculation programs for calculating optimal control values at the associated lattice points are allocated respectively to at least one or some of the plurality of the cores. In addition, each of the cores with which the lattice points are associated respectively is programmed, in a case where an operation area on the two-dimensional orthogonal coordinate system to which a current operating point belongs is an area that is defined by the lattice point associated with each of the cores itself, to transmit, to an interpolation calculation core, an optimal control value at the relevant lattice point that is calculated by each of the cores itself. The interpolation calculation core is programmed to perform an interpolation calculation of an optimal control value at the current operating point using optimal control values at all the lattice points that define the operation area on the two-dimensional orthogonal coordinate system to which the current operating point belongs. In addition, the multicore processor outputs the optimal control value at the current operating point, which is obtained from the interpolation calculation core, as a control target value of each of the actuators.

摘要： A method for estimating steady state values of engine operating characteristics is provided so that engine control can later be based on the estimated values. An amount of change in a specific engine characteristic (for which the steady state values are to be estimated) is set as a product of an unknown value and a dimensionless known value for predetermined times from when a specific engine control parameter is changed. A value of the specific engine characteristic at a given time is calculated as a sum of the products at the given time, with the products respectively corresponding to plural prior changes in the specific engine control parameter. Unknown values are calculated multiple times based on values of the specific engine characteristic measured in a conformance test, and the steady state values of the specific engine characteristic are estimated.

摘要： An apparatus and method of controlling vibration-damping for a vehicular internal combustion engine. The combustion is temporarily stopped in some cylinders among a plurality of cylinders, and the engine is operated by the remaining cylinders. Then, a variable valve mechanism which varies a valve lift amount of at least one of intake and exhaust valves of each cylinder is controlled, to decrease the valve lift amount of at least one of the intake and exhaust valves of each cylinder in which the combustion is temporarily stopped. Further, a rotating electric machine having at least one of functions of an electric motor and a generator is controlled, to apply torque to an output shaft of the engine thereby suppressing torque variation in the output shaft at the time when the combustion is temporarily stopped in some cylinders, so that the torque variation due to uneven explosion intervals is reduced.

摘要： A negative pressure booster according to the present invention is configured in such a manner that a vacuum valve seat member (30) does not move, a reaction disk (25) protrudes and comes into contact only with a reduced diameter portion (24a) of a spacer member (24) under an operation in which an input is equal to or smaller than a preset input. Accordingly, the servo ratio becomes the normal servo ratio. Under the operation in which the input exceeds the preset input, the vacuum valve seat member (30) moves rearward (input side) with respect to a valve body (4) by the pressure in a variable pressure chamber (9), and a reaction disk (25) is significantly protruded to come into contact also with an increased diameter portion (24b) in addition to a reduced diameter portion (24a). Accordingly, although the balanced position in which both a vacuum valve (15) and an atmosphere valve (16) are closed is moved rearward and the servo ratio is increased, a pressure receiving area of a spacer member (24) is increased and the servo ratio is reduced, so that the servo ratio becomes the same as that when the input is equal to or smaller than the preset input.
