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.

Abstract: A method for controlling a vehicle climate control system includes steps of determining that a first predetermined set of conditions are satisfied whereby a heating, ventilation, and air-conditioning (HVAC) system airflow into a passenger cabin will exceed a predetermined HVAC airflow temperature threshold and, if so, automatically implementing a first climate control system operating condition at least reducing the HVAC airflow into the passenger cabin. On determining that a second predetermined set of conditions are satisfied whereby the HVAC airflow into the passenger cabin will satisfy the predetermined HVAC airflow temperature threshold, the method includes a step of automatically implementing a second climate control system operating condition increasing the HVAC airflow into the passenger cabin. Climate control systems for implementing the described methods are provided.
