Abstract:
A method of controlling shifts in a multi-speed transmission includes beginning an initial shift, which changes the transmission from a starting gear to an initial target gear, and executing an adjusted shift, which changes the transmission to an adjusted target gear having higher speed ratio than the initial target gear, when transition conditions are satisfied. The transition conditions include a threshold increase in torque request, which is sufficient to require the transmission to be placed into the adjusted target gear. The transition conditions also include a common controlling clutch, which is an off-going clutch to place the transmission in the adjusted target gear. Executing the adjusted shift does not include placing the transmission in a neutral mode. Furthermore, executing the adjusted shift does not include completing the initial shift.
