ABSTRACT:
The present invention provides a method of adaptively modifying the transmission shift schedule during various driving conditions. The method determines a desirable upshift schedule based upon driving conditions, and adaptively adjusts the transmission shift schedule in accordance with a predefined criteria. This is accomplished by observing vehicle speed and other transmission operating parameters and determining whether an adaptive shift schedule adjustment is required. If the shift schedule is adaptively adjusted, the driving parameters are further monitored to determine at which time the shift schedule may be reset to its initial state.
