INTERNAL-COMBUSTION-ENGINE CONTROL DEVICE

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 engine that includes a cylinder pressure sensor for detecting cylinder pressure in a combustion chamber. The ECU includes an overall controller configured to correct an output signal S transmitted from the cylinder pressure sensor in a cylinder . The overall controller corrects the output signal S from the cylinder pressure sensor in accordance with a correction period calculated based on drive of components of the internal combustion engine , such as a fuel injector
