<P>PROBLEM TO BE SOLVED: To provide an internal combustion engine control device, which is capable of controlling an increase of a matching man-hour while suppressing a control map capacity, and capable of achieving a torque control with high accuracy based on the efficiency of combustion, without depending on various operation conditions and variations including an intake and exhaust VVT. <P>SOLUTION: A torque calculation means performs a torque correction by using the thermal efficiency and the characteristic of a torque curve, which can approximate the relationship between an ignition retard value and a torque generating efficiency by a quadratic function. The torque calculation means includes: calculating a correction coefficient considering an effect of a combustion state change for the change of the intake and exhaust VVT or the like, and an effect on a control operation point; and performing the correction for the change of the intake and exhaust VVT or the like, with respect to the thermal efficiency and torque generating efficiency as well as MBT. <P>COPYRIGHT: (C)2013,JPO&INPIT |
