Judgment Value
MALFUNCTION CRITERIA AND THRESHOLD VALUE REFERENCE
| Malfunction Criteria | Threshold Value |
|---|---|
| fsobd = (sglmd - tglmda) + faf + flaf | ≤ fsobdR1 |
| where, | See MAP 4 |
| sglmd = measured lambda | fsobdR1 = rich side threshold value of fsobd |
| tglmda = target lambda | |
| faf = main feedback compensation coefficient every 64 milliseconds | |
| flaf = main feedback learning compensation coefficient |
