摘要： A branched power transmission with several transmission ratio ranges with a steplessly adjustable transmission ratio includes a drive shaft (2) that is connected to both shafts (14, 16) of a variable speed unit (4) through a distributor transmission (12), which shafts in turn are connected with the input shafts (18, 20) of a parallel gearbox (20) through respective clutches (K13, K2R). Two transmission ratio ranges only differ from each other through the transmission ratio of an input shaft of the parallel gearbox and its output shaft. Additionally, the power-producing transmission can include an electrical machine (61). A further embodiment of a transmission with a steplessly adjustable transmission ratio includes a variable speed unit, a first planetary transmission that is connected with a drive shaft, the input shaft of the variable speed unit and a connecting shaft, as well as a second planetary transmission that is connected with the connecting shaft of the output shaft of the variable speed unit and an output shaft, and an E-machine that is non-rotatably connected with the connecting shaft.

摘要： A target engine rotational speed depending at least upon the position of an accelerator pedal position and a motor vehicle speed is determined in a method for controlling the operation of a motor vehicle drive train having a drive motor and a branched power transmission with several steplessly adjustable transmission ratio regions, between which shifting takes place at a predetermined range shift transmission ratio. A transmission ratio corresponding to the target engine rotational speed and vehicle speed is determined and set, whereby the change with respect to time of the accelerator pedal position and/or the change with respect to time of the target engine rotational speed is used for determining the target engine rotational speed and is filtered when a difference between the actual transmission ratio and a transmission ratio shift range falls below a limit value.
