Abstract:
Various methods for estimating electric actuator temperature during certain operational windows are provided. In one example, a method comprises adjusting an electric motor to position a wastegate at a desired wastegate position, while during selected conditions, deviating from the desired position by at least one full half-turn of the motor and indicating motor temperature based on winding resistance averaged over the full half-turn.
