Methods And Systems For Controlling On-Board Diagnostics
First Claim
1. A method of controlling a motor vehicle, the method comprising:
- determining a feedback correction factor;
retrieving a predetermined range associated with the feedback correction factor;
entering a judging mode if the feedback correction factor is within the predetermined range, wherein the judging mode includes judging at least one on-board diagnostic item; and
entering a non-judging mode if the feedback correction factor is outside the predetermined range, wherein the non-judging mode includes ignoring at least one on-board diagnostic item.

Abstract
Embodiments provide systems and methods for using a feedback correction factor to determine whether a motor vehicle should be placed in a judging or non-judging mode regarding the on-board diagnostic system. If the feedback correction factor is within a predetermined range, the vehicle is placed in a judging mode. If the feedback correction factor is outside a predetermined range, the vehicle is placed in a non-judging mode. Methods and systems for using an engine oil temperature to determine whether a motor vehicle should be placed in a judging or non-judging mode regarding the on-board diagnostic system are disclosed. If an engine oil temperature, or predicted engine oil temperature, is below a predetermined temperature, the motor vehicle is placed in a non-judging mode. If an engine oil temperature, or predicted engine oil temperature, is above a predetermined temperature, the motor vehicle is placed in a judging mode.
