PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of calculating accurately a friction torque of the internal combustion engine, and correcting densely a friction characteristic. SOLUTION: This control device of the internal combustion engine calculates the friction torque of the internal combustion engine. An illustrated torque calculation means calculates an illustrated torque based on a cylinder internal pressure, and a net torque acquisition means acquires a net torque detected by a torque sensor. A friction characteristic correction means calculates the friction torque in the internal combustion engine based on the illustrated torque and the net torque, and always correct dynamically the friction characteristic by the friction torque. Hereby, the friction torque can be corrected densely relative to fine individual operation state. Consequently, output torque control of the internal combustion engine can be performed accurately following the corrected friction characteristic. COPYRIGHT: (C)2008,JPO&INPIT
