Development of Output Torque Equation for Double Swap Shift Control

In this paper, the equations of motion for output torque are developed for the 62TE transmission. The 62TE is an innovative six-speed transmission comprised of an existing four-speed transmission, the 41TE with an underdrive assembly added on the transfer shaft centerline. Understanding the behavior influencing the output torque profile is critical to achieving good shift quality[1]. The application of lever analogy [2] resulted in a control strategy that was based on the physics of the system.
