Abstract
A turbocharger that includes a turbine and a compressor, an electric supercharger that is arranged in an intake passage, and a control device that increases a rotational speed of the electric supercharger upon receipt of a torque increase request with respect to the internal combustion engine are provided. During a process in which the rotational speed of the electric supercharger is increasing, if the rotational speed arrives at a predetermined switching rotational speed “Ntec”, the control device decreases a rate of increase in the rotational speed from a first rate of increase “Nteup1” to a second rate of increase “Nteup2” (<Nteup1). At such time, the control device sets each of “Ntec” and “Nteup2” based on at least any one of an engine speed, a rate of increase in the engine speed, and a supercharging pressure difference between a target supercharging pressure and an actual supercharging pressure.
