Abstract
Various methods for controlling a wastegate with an electric actuator including a bias are provided. In one example, the actuator is supplied with a first current when moving a wastegate valve toward a fully open position, and is supplied with a second current when moving a wastegate toward a fully closed position. The methods may ensure appropriate supply of boost to an engine even in the event of wastegate degradation while enabling engine downsizing.
