1.15.7.3 Rationality check

P152B (VFZNPmin) 

The fuel cut-off check compares the vehicle speed during fuel cut-off condition. It is assumed that the vehicle must move during this condition. To cover the special fuel cut-off case when the driver has rev-up the engine at standstill the check must be debounced for a calibrated period of time.

If the vehicle is in fuel cut-off condition and the vehicle speed lies below a calibrated threshold for a calibrated period of time, a VFZNPmin will be set.
