摘要：The invention relates to a method for controlling a drive train of a motorvehicle with an internal combustion engine (1), an electrical machine (3) operable in motormode and in generator mode, a clutch (2) arranged between the internal combustionengine (1) and the electrical machine (3), and an automatic gearbox (5) arranged betweenthe electrical machine (3) and the drive wheels (6), wherein a gear change in the automaticgearbox (5) can be initiated manually by the driver. The method is characterized in thatduring overrun mode of the motor vehicle, in which the electrical machine (3) is operatedin generator mode, the following steps are performed, after a manual initiation of thegear change from a source gear into a target gear by the driver: - the clutch (2) is at leastpartially disengaged if it is not already disengaged; - the speed (nVM) of the internalcombustion engine (1) is brought to a speed level (nZ) corresponding to the target gearand to the current speed of the motor vehicle and continues to be regulated; - the gearchange is performed in the automatic gearbox (5); - the clutch (2) is engaged uponreaching a synchronous speed (nVM, nE) of the internal combustion engine (1) and theelectrical machine (3). The recuperation can thereby be preserved during the gear change
and the driver obtains feedback corresponding to that of a non-hybridized or non-recuperative motor vehicle after his initiation of the gear change.
