To excellently reduce superimposition of large noise on a desired control quantity of an on-vehicle actuator, without impairing responsiveness of a system, in a vehicle control apparatus.
With the use of a model expression (Fig. 9C) including a desired value of an in-cylinder air amount being a controlled object of the system and a predetermined engine parameter such as an engine speed ne as an input value, a desired throttle opening degree ref required to control the in-cylinder air amount to the desired value is calculated. In this model expression, a parameter such as the engine speed ne that oscillates at a relatively high frequency is excluded from a subject of differentiation, and the desired in-cylinder air amount value only is included in the subject of differentiation.
