CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE

A control apparatus (50) for an internal combustion engine (10, 70) executes shaft heating control that controls the energization of an electric motor (22, 74b) so that a driving torque and a braking torque are alternately imparted from the electric motor to a rotary shaft when the temperature of a lubricating oil (lubricant) is less than or equal to a predetermined value. According to the shaft heating control, in a case where a target intake air pressure Pt is higher than an actual intake air pressure P, a proportion that a driving torque impartation period Ä D occupies in a cycle T is increased relative to a case where Pt and P are equal or substantially equal, and in a case where Pt is lower than P, the proportion Ä D that the driving torque impartation period occupies in the cycle T is decreased relative to a case where Pt and P are equal or substantially equal.
