To provide a technology capable of quickly stabilizing the engine rotational speed by obtaining friction torque early in a control device for internal combustion engine.
The control device is equipped with an ignition timing operating means for performing at least one time of each of advancing and delaying the ignition timing compared with a reference value during a rotational speed transition period from when the internal combustion engine is started until when the engine rotational speed is transferred at a constant rotational speed, a friction torque estimation means for estimating the friction torque based on generated torque when the ignition timing is operated, a memory means for storing the friction torque which becomes a reference when the ignition timing is operated, and a correction amount calculation means for calculating a correction amount of the friction torque by comparing the friction torque estimated by the friction torque estimation means with the friction torque which becomes the reference stored in the memory means.
