A control device used for an internal combustion engine and capable of determining an actuator operation amount is provided. The control device includes a computation element that uses engine status amounts to compute the actuator operation amount. The computation element uses a model that includes a plurality of submodels arranged in a hierarchical sequence. The computation element computes the actuator operation amount by using a parameter calculated by the lowest level submodel and changes the number of higher-level submodels to be used in combination...

1. A control device for operating one or more actuators to control an operation of an internal combustion engine, the control device comprising: a plurality of different sensors that acquire a plurality of different status amounts indicative of the status of the internal combustion engine (hereinafter referred to as the engine status amounts); anda computation element that computes an actuator operation amount from the engine status amounts, the computation element using a model during a process of the computation;wherein the model includes a plurality of submodels arranged in a hierarchical sequence;wherein, when parameters are calculated by two consecutive submodels arranged in the hierarchical sequence, there is a means-end relation between a parameter calculated by a lower-level submodel and a parameter calculated by a higher-level submodel;wherein the highest level submodel calculates a parameter that is a numerical value representing a request concerning the performance of the internal combustion engine, and is built so as to calculate the parameter by using the engine status amounts;wherein submodels other than the highest level submodel are built so that when an immediately higher-level submodel is used, a parameter calculated by the higher-level submodel is handled as a target value to calculate a parameter for achieving the target value from the engine status amounts, and that when the immediately higher-level submodel is not used, the parameter is calculated from the engine status amounts only; andwherein the computation element computes the actuator operation amount by using a parameter calculated by the lowest level submodel and changes the number of higher-level submodels to be used in combination with the lowest level submodel in accordance with the operation status of the internal combustion engine. 2. The control device according to claim 1, wherein the computation element stores a numerical value serving as a computational load index (hereinafter referred to as the load index value) for each submodel and for each operation state of the internal combustion engine, and raises the hierarchical level of a high-level submodel used in combination with the lowest level submodel within a range within which a reference value is not exceeded by an integrated value of the load index value. 3. The control device according to claim 2, wherein the computation element includes a plurality of differently structured models in order to respectively compute different actuator operation amounts; wherein the plurality of models are prioritized; and wherein the computation element raises the hierarchical level of the higher-level submodel to be used in combination with the lowest level submodel, in order from the highest priority model to the lowest, within a range within which the reference value is not exceeded by the integrated value of the load index value. 4. The control device according to claim 3, wherein the computation element changes the priorities of the plurality of models in accordance with the operation status of the internal combustion engine. 5. A control device for operating one or more actuators to control an operation of an internal combustion engine, the control device comprising: a plurality of different sensors that acquire a plurality of different status amounts indicative of the status of the internal combustion engine (hereinafter referred to as the engine status amounts); anda computation element that computes an actuator operation amount from the engine status amounts, the computation element using a model during a process of the computation;wherein the computation element has a model group, which includes a plurality of models differing in scale for computing the same actuator operation amount;wherein the plurality of models are arranged in a sequence according to scale of computation executed by each model;wherein the larger-scale one of two consecutive models arranged in the sequence includes a high-level submodel, which is located upstream in an information pathway, and a low-level submodel, which is located downstream in the information pathway and coupled to the high-level submodel;wherein the smaller-scale one of two consecutive models arranged in the sequence corresponds to the low-level submodel which constitutes the larger-scale model;wherein the low-level submodel is built so as to use a parameter calculated by the high-level submodel as a target value and calculate a parameter for achieving the target value from the engine status amounts;wherein the high-level submodel is built so that when the high-level submodel constitutes the largest scale model, the high-level submodel calculates a parameter that is a numerical value representing a request concerning the performance of the internal combustion engine from the engine status amounts, and that when the high-level submodel constitutes a model other than the largest scale model, the high-level submodel predicts a parameter calculated by a high-level submodel of an immediate larger scale model from the engine status amounts and calculates a parameter for achieving the predicted parameter; andwherein the computation element selects a model for use in the computation of the actuator operation amount from the model group in accordance with the operation status of the internal combustion engine, and computes the actuator operation amount by using a parameter calculated by the selected model. 6. The control device according to claim 5, wherein the computation element has a model independent of the model group in order to compute another operation amount than the actuator operation amount; and wherein the computation element stores a numerical value serving as a computational load index (hereinafter referred to as the load index value) for each model and for each operation state of the internal combustion engine, and selects a model from the model group so that an integrated value of the load index value becomes maximized without exceeding a reference value. 7. The control device according to claim 5, wherein the computation element includes a plurality of model groups in order to respectively compute different actuator operation amounts; wherein the plurality of model groups are prioritized; and wherein the computation element stores a numerical value serving as a computational load index (hereinafter referred to as the load index value) for each model and for each operation state of the internal combustion engine, and enlarges the scale of the model to be used for the computation of the actuator operation amounts, in order from the highest priority model group to the lowest, within a range within which an integrated value of the load index value does not exceed the reference value. 8. The control device according to claim 7, wherein the computation element changes the priorities of the plurality of model groups in accordance with the operation status of the internal combustion engine.
