Abstract
A supercharging system includes an internal combustion engine, a supercharger, and an electronic control unit configured to compute an integrated value of the intake air amount during a predetermined period on the basis of a detected result of a first sensor. The predetermined period is a period from a start of an increase in the supercharging pressure to an end of the increase at the time when the intake air amount is increased in a state where no command to reduce the supercharging pressure by a supercharging pressure reduction mechanism is issued. The electronic control unit is configured to acquire a peak supercharging pressure from a detected result of a second sensor. The electronic control unit is configured to determine whether the supercharging system has an abnormality on the basis of the integrated value of the intake air amount and the peak supercharging pressure.
