Abstract (en)

[origin: WO2008132012A1] The invention relates to a method for operating an automotive drive train comprising at least one automatic transmission and one drive unit. According to said method, a starting speed is determined during starting of the motor vehicle, a starting process being triggered using the determined starting speed by closing a starting element, especially a starting clutch. According to the invention, the starting speed can be individually adjusted by a driver in such a manner that when the automatic transmission is in the selector position neutral, the engine speed of the drive unit can be determined by the driver by actuating the gas pedal and that once the automatic transmission is transferred from neutral to a selector position corresponding to forward gear or reverse gear the engine speed of the drive unit prevailing during the transfer is used as the starting speed.
