Abstract
Provided is an internal-combustion-engine control device that minimizes a detection error of a cylinder pressure sensor used in a control of an internal combustion engine. The internal-combustion-engine control device is an electronic control unit (ECU)for an internal combustion enginethat includes a cylinder pressure sensorfor detecting cylinder pressure in a combustion chamber. The ECUincludes an overall controllerconfigured to correct an output signal Stransmitted from the cylinder pressure sensorin a cylinder. The overall controllercorrects the output signal Sfrom the cylinder pressure sensorin accordance with a correction period calculated based on drive of components of the internal combustion engine, such as a fuel injector
