초록 ▼

The present invention relates to a method and apparatus for three dimensional calibration of an on-board diagnostics system. In one embodiment, the present invention is a method for calibrating an on-board diagnostic system for an automobile including the steps of generating a three dimensional surface corresponding to an engine operating under a first condition, generating a three dimensional surface corresponding to the engine operating under a second condition, and generating a three dimensional threshold surface using the three dimensional surface corresponding to the engine operating under the first condition and the three dimensional surface corresponding to the engine operating under the second condition.

대표청구항 ▼

What is claimed is: 1. A method for calibrating an on-board diagnostic system for an automobile comprising the steps of:generating, using a calibration unit and engine operation data of an engine operating under a first condition, a three dimensional surface corresponding to the engine operating under the first condition;generating, using the calibration unit and engine operation data of the engine operating under a second condition, a three dimensional surface corresponding to the engine operating under the second condition; andgenerating, using the calibration unit, a three dimensional threshold surface using the three dimensional surface corresponding to the engine operating under the first condition and the three dimensional surface corresponding to the engine operating under the second condition.
