Patent ID: 7137252

Claim:
An electronic controller for a variable nozzle control apparatus comprising: an engine electronic control unit for identifying an operating situation of an engine and outputting a vane opening signal; and an electronic control actuator for controlling an opening of a vane in a turbocharger in response to the vane opening signal, wherein the electronic control actuator comprises: an angle sensor that outputs an actual angle signal that corresponds to a rotation angle of an output shaft that drives said vane; an electronic control circuit that receives said vane opening signal and that provides an output signal based upon the vane opening signal and the actual angle signal; and a driver that drives the output shaft based upon the output signal, wherein the electronic control circuit comprises a wiping processor that stores at least one of a first working angle of the output shaft corresponding to a vane fully closed state and a second working angle of the output shaft corresponding to a vane fully open state.
