Abstract
The invention relates to an urban driving operating method for an electronically controlled automatic transmission in which a driving speed characteristic (vf) is determined and it is possible to recognize an urban driving state when the driving speed characteristic (vf) is within a presettable value range with an upper limit and in which in addition a driving activity characteristic (FCOUNTER) is continuously determined. It is proposed according to the invention that the urban driving state be recognized when the driving activity characteristic (FCOUNTER) is also within a presettable value range with an upper limit and that a drive program optimized for the urban driving state be accessed.
