Abstract
A control apparatus for the internal combustion engine has a multicore processor mounted with a plurality of the cores, calculates various tasks regarding an operation of the internal combustion engine, and distributes the tasks to the plurality of the cores respectively to perform a calculation, and a controller that makes the number of cores for use in the calculation smaller while fuel cutoff is carried out than before the fuel cutoff is carried out. The controller selects, as a designated core, at least one of the cores for use in a specific calculation associated with combustion of the internal combustion engine. The controller stops the designated core from being used while fuel cutoff is carried out. As the specific calculation associated with combustion, for example, it is possible to mention a combustion forecasting calculation of a cylinder model, a temperature forecasting calculation of a catalyst temperature estimation model, and a fuel adhesion amount forecasting calculation of a fuel adhesion model.
