摘要：The invention relates to an arrangement and a method for controlling an
adjusting speed for a change of an actual transmission ratio into a steady-state desiredtransmission ratio (shifting operation) for a continuously variable transmission mounted inthe drive train of a motor vehicle. In the arrangement of the invention, it is provided thatthe shifting operation is subdivided into individual periods (dT) of fixed duration. Duringeach period (dT), a dynamic desired transmission ratio (u) is determined by multiplyingthe steady-state desired transmission ratio (u) by a gradient (u). The change of the actualtransmission ratio (u) into a dynamic desired transmission ratio (u) of each period (dT)takes place with a constant adjusting speed (v).
