<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine control device which does not generate discontinuous estimation values outputted from a plant model even in the change of operating conditions regarding an internal combustion engine including the plant model for outputting the estimation value of control amount of an internal combustion engine by defining the control amount of an actuator for controlling the internal combustion engine as an input parameter. <P>SOLUTION: The internal combustion engine control device includes: the plant model which outputs the estimation value of the control amount of the internal combustion engine (supercharging pressure, EGR ratio) by defining the control amount of the actuator for controlling the internal combustion engine (EGR valve opening degree, variable nozzle opening degree of variable nozzle type turbo supercharger, opening degree of exhaust throttle) as the input parameter; and a coefficient output model which outputs a coefficient used for calculating the plant model. The coefficient output model linearly outputs the coefficient for continuously changing the estimation value outputted from the plant model according to the change of the operating conditions by having an engine speed of the internal combustion engine and a fuel injection amount as the input parameter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
