Abstract

To this point, requirements imposed on the transmission have been introduced that are satisfied via multiple gears and appropriate gear ratio change. In Sect. 2.1, this chapter describes the various phases of a shift sequence and compares the ideal shift sequence with shift sequences that are not acceptable in terms of quality. The shift-related torque changes as well as the engine excitations and torque variations cause the powertrain to vibrate. In Sect. 2.2, the occurring vibrations and eigen frequencies are discussed, as are measures for reducing these vibration occurrences.
