Method for controlling automatic transmission in motor vehicles, involves outputting request command for opening or leaving open clutch of current reference-gear by electronic engine control unit for controlling internal combustion engine

摘要

The method involves outputting a request command (S-csn) for opening or leaving open a clutch (4) of the current reference-gear despite of engaged driving position (D) by an electronic engine control unit (5) for controlling the internal combustion engine (1) in the presence of defined conditions in a transmission control unit (7). The defined condition is an activated vehicle brake (B) or an actual engine temperature, which lies below a predetermined minimum temperature (T-M).
