    • An object of the invention is to satisfy various constraints associated with supercharging pressure control even during transitional operation in a turbocharged diesel engine of which a supercharging pressure is actively controllable through operation of an actuator. The control device calculates a steady target value that is a target value of the supercharging pressure during steady operation on the basis of an engine rotation speed and a fuel injection amount, and operates the actuator through feedback control such that an actual supercharging pressure calculated from a signal of a supercharging pressure sensor is brought close to the steady target value. However, when any condition of a plurality of different conditions, which can be satisfied during transitional operation, is satisfied, a transitional target value of the supercharging pressure, suitable for the satisfied condition is calculated in accordance with a calculation rule prepared for each condition. At this time, when there is one transitional target value, the transitional target value is selected, and, when there are a plurality of transitional target values at the same time, one of the transitional target values is selected in accordance with a priority order determined on the basis of an acceleration. A target value of feedback control is changed from the steady target value to the selected transitional target value.
