Zusammenfassung:	A method for adjusting a ratio of a continuously variable automatic transmission where a nominal ratio is determined according to an accelerator pedal signal value. The nominal ratio is determined according to a modified accelerator pedal signal. When the periodic curve of the accelerator pedal signal has a relative extreme value to the modified accelerator pedal signal, a starting value is assigned which is equal to this extreme value. Until the value of the modified accelerator pedal signal is again equal to the value of the unmodified accelerator pedal signal, the value of the modified accelerator pedal signal is determined by a transfer function.
