Abstract

A method for control of an automatic transmission for a motor vehicle equipped with cruise control consists in that during cruise control of the transmission control changes to a separate driving program which is function of external influences, especially of the road inclination. This driving program is updated according to external influences. In the “set” state, change is made to the separate driving program and in the “restore” state the control can be adjusted so that the separate driving program be activated immediately or not until reaching the “set” control state.
