Synchronous automatic transmission up-shift control utilizing input torque signal
A synchronous automatic transmission up-shift control utilizes input torque measurements. The input torque is measured during an up-shift having preparatory, torque, and inertia phases. Target input torque profiles for the torque and inertia phases are determined based on the input torque during the preparatory phase. During the torque phase, an engine torque is controlled to cause the input torque to achieve the target profile for the torque phase. During the inertia phase, an on-coming clutch is controlled to cause the input torque to achieve the target profile for the inertia phase.
