  • Patent number: 5737712
    Abstract: A method of establishing an adaptive pressure term in an automatic transmission having a pressure command developed from a base line pressure term and an adaptive pressure term extends implementation of adaptive pressure corrections during non-ideal periods of operation such as low temperatures, short operating cycles and driver variations by establishing an adaptive pressure term proportional to a measure of confidence in a pressure correction term calculated at each ratio change of the transmission. The measure of confidence is determined according to a variety of functions of predetermined powertrain operating parameters and measures of criticality.
