SYSTEM AND METHOD FOR CONTROLLING VARIABLE TURBOCHARGER

摘要

A system for controlling a variable turbocharger includes: a first controller outputting a duty value for adjusting an opening degree of a vane of a turbocharger, and a second controller checking opening or closing operations of the vane when the first controller adjusts the opening degree of the vane. In particular, the second controller outputs a corrected duty value by correcting the output duty value, based on a correction map, in consideration of a back pressure according to whether the vane is opened or closed.

1. A system for controlling a variable turbocharger, comprising:
a first controller configured to output a duty value adjusting an opening degree of a vane of a turbocharger; and a second controller configured to check whether the vane is in an opening or a closing operation when the first controller adjusts the opening degree of the vane, and in consideration of a back pressure according to whether the vane is opened or closed, the second controller outputs a corrected duty value by which the output duty value is corrected based on a correction map.
