Abstract
A method and system for the cancellation of transmission shift delay as a function of an optimum target temperature is disclosed. Once the pre-selected optimum target is achieved the shift delay is cancelled and the transmission is upshifted. Thus the disclosed inventive concept is based the cancellation of the shift delay on achieving climate control air conditioning comfort targets. Such comfort targets could include one or more of the measured HVAC evaporator temperature, the HVAC discharge temperature, or the in-vehicle cabin temperatures. When a temperature sensor measuring the selected temperature reaches the pre-selected target temperature the shift delay may be cancelled and the transmission may be upshifted, thus maximizing passenger comfort while minimizing fuel consumption. Having the shift delay based upon the achievement of specific measurable comfort targets in the form of target temperatures rather than a set time period allows optimization between cabin comfort and fuel efficiency.
