Appeal No. 1997-1873
Application 08/300,855
The invention relates to a method for judging whether or not an engine is in a steady state
operation during which the monitoring for diagnosis is performed.
Independent claim 1 is reproduced as follows:
1. A method of judging a steady state operation of an engine by monitoring at least one engine
parameter for a predetermined period of monitoring, comprising:
turning on an ignition switch and starting said engine;
detecting an engine parameter;
memorizing an initial value of said engine parameter at the start of said period of monitoring;
calculating a difference between said initial value of said engine parameter and said detected
engine parameter;
discontinuing monitoring if said difference is outside of a predetermined restriction width before
the end of said period of monitoring; and
judging that said engine is in a steady state operation if said difference is within a predetermined
restriction width at the end of said period of monitoring.
The Examiner relies on the following references:
