Abstract

A wastegate opens and closes the flow path of a bypass passage that bypasses the turbine of a forced-induction device. A processor changes the drive current for the electric actuator in a stepwise manner from a state where the wastegate is stationary in a given standstill position. The amount of change in the drive current that is made until the wastegate is determined to be moved is learned as a learning value. A requested drive current for moving the wastegate to a target opening degree is corrected based on the learning value.
