  • Transmission shift control with engine torque control
    Publication number: 20040014563
    Abstract: A transmission controller determines a requested engine torque value. For an upshift the requested engine torque value is determined as a function of slippage of one of an off-going clutch. For a downshift, the requested engine torque value is determined as a function of actual sensed engine torque. The requested torque value is sent to an engine controller which controls the engine so that the engine generates the requested engine torque. Then the appropriate transmission clutches are swapped to complete the requested shift while the engine torque is controlled. The engine controller also limits engine torque to the requested engine torque value.
