摘要 |
A method of shifting an automatic transmission of a motor vehicle having a hydrodynamic converter (6). The method comprising the steps of detecting a presence of predetermined stopping conditions; determining that a driver of the motor vehicle intends to cause the motor vehicle to change from a driving state to a stopped state, based on the presence of one of the predetermined stopping conditions; and automatically shifting the automatic transmission (8) into a standby mode, before the driving state has concluded. The shifting into the standby mode typically occurs when a rotational speed of the hydrodynamic converter (6) decreases to less than a rotational speed (120) of a motor and the retarder apparatus (10), of the automatic transmission, is disengaged no later than a time by which shifting into the standby mode occurs. |
