Abstract: A control device in an IC engine estimates a future cylinder inside air quantity by delaying an operation of a throttle to make responsiveness of the IC engine and estimation precision of the cylinder inside air quantity compatible with each other. A delay time is provided in a calculation process until an instructed TA is outputted after a required KL is inputted. When calculation timing of a fuel injection quantity comes, an actual KL which is achieved in a time ahead by the delay time from the present time is estimated by using an air response model. When a read-ahead time of an intake valve exceeds the delay time, a change amount of the actual KL is estimated by using an air response model with a deviation between an estimated KL after td and a target KL set as a step input value.

Abstract: A torque control device for a power system and facilitates the addition of a new torque control actuator. A target torque signal according to a target torque for the power system is distributed to each actuator in a predetermined distribution priority order. A signal processing filter is mounted on a signal input section of each actuator and allows only a portion of distributed signal that matches the operation characteristics of the actuator to pass through as a command signal for the actuator.

Abstract: A control apparatus for an internal combustion engine is provided that can precisely reflect requirements relating to performance of the internal combustion engine in a control amount of each actuator by compensating for weaknesses in the so-called torque demand control. A requirement value of each of torque, efficiency, and an air-fuel ratio, and engine information are inputted to an engine inverse model. The engine inverse model is then used to calculate actuator requirement values for achieving those requirement values. An actuator direct requirement value directly required of each of actuators is also acquired. Control of the actuators is adapted to be changed between that according to the actuator requirement value and that according to the actuator direct requirement value.

Abstract: A control apparatus for an internal combustion engine that accurately incorporates demands related to various capabilities of the internal combustion engine. A demand output unit outputs various capability demands of the internal combustion engine, expressed in terms of either torque, efficiency, or an air-fuel ratio data. A torque mediation unit collects only the demand values expressed in terms of torque, and mediates the torque demand values into one. An efficiency mediation unit collects the demand values expressed in terms of efficiency and mediates the efficiency demand values into one. An air-fuel ratio mediation unit collects the demand values expressed in terms of the air-fuel ratio and mediates the air-fuel ratio demand values into one. A control variable computing unit computes control variables of actuators, based upon the torque demand value, efficiency demand value, and air-fuel ratio demand value output from the mediation units.

Abstract: A control apparatus for a vehicle drive unit including a control structure of a hierarchical type having a demand generation level, a mediation level, and a control variable setting level and a signal is transmitted in one direction from a higher level of hierarchy to a lower level of hierarchy. The demand generation level includes demand output elements for each capability. The mediation level includes mediation elements, each corresponding to a classified category of demands. Each of the mediation elements collects demand values of the category of which the mediation elements are in charge and performs mediation according to a rule to arrive at a single demand value. The control variable setting level includes an adjuster portion adjusting each of the mediated demand values based on a relationship between each other and control variable calculation elements calculating a control variable of each of a plurality of actuators based on the adjusted demand value.
