ABSTRACT:
Flare control is provided for downshifts in a computer controlled automatic transmission by providing an adaptive pressure term which is adjusted in response to detected flare conditions. During a downshift, engine acceleration is monitored and flare is detected when negative engine acceleration remains below a predetermined level for a predetermined duration. The level of engine acceleration indicative of flare changes with vehicle speed.
