Internal Combustion Engine Control Device

Provided is an internal combustion engine control device capable of reducing a control error of the ignition timing as compared with the conventional technique. The internal combustion engine control device of the present disclosure includes a neural network model that receives three or more variables including at least a rotation speed, a load, and another specific variable of an internal combustion engine as inputs and outputs a control amount of the internal combustion engine. The neural network model includes a first neural network model having a reference value of the specific variable as an input and a second neural network model having a current value of the specific variable as an input. The internal combustion engine control device of the present disclosure corrects a reference value of the control amount calculated based on the rotation speed and the load using a difference or a ratio between the output of the first neural network model and the output of the second neural network model as a correction amount.
