Abstract: During a transmission upshift, a torque capacity of an off-going clutch is maintained at a non-zero state during the transition from the torque phase to the inertia phase and throughout a substantial portion of the inertia phase. This permits the inertia phase to be completed faster without an unacceptable increase in output torque during the torque phase. Monotonically reducing the off-going clutch torque and using feedback from an output torque sensor enable sufficiently precise control of the off-going clutch torque capacity during this interval.

Abstract: A method is provided for disengaging a tooth clutch of an inactive gear in a dual clutch transmission during vehicle acceleration or retardation. The dual clutch transmission includes an engaged active gear through which torque is transmitted between an engine and driven wheels, an engaged inactive gear to be disengaged, and an electric motor drivingly connected to a shaft of the inactive gear. The method includes controlling the electric motor to provide a compensational torque for temporarily decreasing or substantially eliminating torque transferred by the tooth clutch of the inactive gear, and disengaging the engaged inactive gear. The disclosure also concerns a corresponding dual clutch transmission, a computer program, a computer readable medium, and an electronic control unit for controlling the electric motor of a dual clutch transmission.

Abstract: An automatic transmission shift control device include a controller that is programmed to shift an automatic transmission by issuing a command for switching an interference shift element from an engaged state to a disengaged state, and by issuing a command for switching a friction shift element from a released state to a locked state. The controller includes a progressive friction-shift-element switchover section which causes progressive switching of the friction shift element from the released state to the locked state prior to the command for switching of the interference shift element from the engaged state to the disengaged state. The controller includes an interference-shift-element switchover section which causes the switching of the interference shift element from the engaged state to the disengaged state when transmission torque of the interference shift element decreases to a predetermined value as the friction shift element progressively switches from the released state to the locked state.
