Abstract: Clutch control values are determined via a method in a vehicle during a power-on upshift. Pressure to an offgoing clutch is decreased to a calibrated holding pressure after onset of the upshift. Proportional-integral-derivative (PID) logic of a controller is used to introduce a calibrated error into a pressure command to the offgoing clutch during fill of the oncoming clutch. This causes a calibrated slip to occur across the offgoing clutch, and a resultant threshold amount of flare to occur in turbine speed. The slip and flare are held using the PID logic. The pressure/torque relationship of the offgoing clutch is recorded. A fill level of the oncoming clutch is determined using a trajectory of an integrator term of the PID logic. A control value of the oncoming or the offgoing clutch is adjusted using at least one of the fill level, the recorded clutch pressure, and the recorded clutch torque.
