Patent ID: 8738249

Claim:
A method for an automatic transmission having gearing defining multiple torque flow paths from an input shaft to an output shaft and further having an off-going clutch (“OGC”) and an on-coming clutch (“OCC”) for shifting from a low gear configuration to a high gear configuration during a ratio up-shift event having a preparatory phase, a torque phase, and an inertia phase, the method comprising: during the up-shift event, measuring input torque using an input torque sensor in communication with the input shaft; determining a target input torque profile for the torque phase and a target input torque profile for the inertia phase each based on the input torque measured during the preparatory phase; during the torque phase, controlling an engine torque to cause the input torque to achieve the target input torque profile for the torque phase; and during the inertia phase, controlling the OCC to cause the input torque to achieve the target input torque profile for the inertia phase.
