Abstract
For a power-on gear shift sequence of AMTs, shift shock may be caused by the operations of clutch disengagement (together with the engine torque reduction) and clutch engagement (together with the engine torque restoration). In this chapter, the engagement control is discussed, while the clutch disengagement control was addressed in Chap. 6. After the dynamics and control problems of gear upshift and downshift of an AMT are described in detail, model predictive control (MPC) is adopted to address the challenging control requirements. It is demonstrated through simulations that a very short torque interruption time can be achieved, while the shift shock is kept small enough.
