Method for reducing the thermal load on an automatic transmission of a motor vehicle in emergency operating mode

摘要

The invention relates to an automatic transmission of a motor vehicle which is controlled by an electronic transmission control system which continuously exchanges signals with a digital engine electronics system of an internal combustion engine. To reduce the thermal load on the automatic transmission in emergency operating mode, a transmission-independent program module (M1) of the digital engine electronics system sets an admissible maximum vehicle speed for the emergency operating mode (v_max_not) or an admissible maximum engine speed for the emergency operating mode (n_mot_max_not).
