PROBLEM TO BE SOLVED: To improve the fuel economy of an internal combustion engine in a case of actuating a motor so as to assist in supercharging using exhaust gas energy in a high-rotation, heavy-load region.SOLUTION: An internal combustion engine control device comprises: a turbocharger 22; an electric supercharger 24; and a WGV 46 opening or closing an exhaust bypass passage 44. In a single supercharging region where a torque index value is lower than a torque boundary value TQ2, the degree of opening of the WGV is controlled so as to decrease in response to an increase of engine torque. Furthermore, in a twin supercharging region where the torque index value is equal to or higher than the torque boundary value TQ2, the degree of opening of the WGV is controlled to increase in response to the increase of the engine torque and a motor 24b is actuated for supercharging.SELECTED DRAWING: Figure 4 |
