摘要

PROBLEM TO BE SOLVED: To provide a temperature detecting device for a cylinder pressure sensor capable of detecting the temperature of the cylinder pressure sensor without using a temperature sensor, and to provide, using temperatures detected by the cylinder pressure sensor, a detecting device for a cylinder pressure capable of accurately detecting the cylinder pressure and a control device for an internal combustion engine capable of appropriately controlling the internal combustion engine.;SOLUTION: The temperature detecting device for the cylinder pressure sensor 4 is equipped with a drift parameter calculating means 2 for calculating a drift parameter driftave indicating a drift of the cylinder pressure sensor 4, and a temperature detecting means 2 for detecting a temperature TempPS of the cylinder pressure sensor 4. The detecting device for cylinder pressure is equipped with a cylinder pressure correcting means 2 for correcting a cylinder pressure pcyl in response to the temperature TempPS of the cylinder pressure sensor 4. The control device for an internal combustion engine is equipped with a control input setting means 2 for setting a control input Tout of the internal combustion engine 3, and a control input correcting means 2 for correcting the control input in response to the temperature TempPS of the cylinder pressure sensor 4.;COPYRIGHT: (C)2006,JPO&NCIPI
