  • Patent number: 10759265
    Abstract: A transmission having five planetary gearsets and seven shift elements for achieving various ratios between drive and output shafts. A forward gearset has three shafts. Two intermediate gearsets have four shafts. Two main gearsets have at least four shafts. Depending on the shift states of the second and third shift elements, the forward gearset can generate two rotational speeds at the output side, which transfer from a forward gearset shaft to an intermediate gearset shaft. Depending on the shift states of the first to fifth shift elements, the intermediate gearset can generate eight rotational speeds at the output side, which pass from another intermediate gearset shaft to a main gearset shaft. Depending on the shift states of the seven shift elements, the main gearset can generate up to fourteen forward and two reverse gears at the output side, which are transferred by another main gearset shaft to the output shaft.

  • Patent number: 10654464
    Abstract: A method for compensation of a support torque at a combustion engine and transmission which provide an overlay of combustion engine and electric machine. The combustion engine, the electric machine, and a transmission gearset are connected with each other via a planetary gearset, which is positioned in front of a downstream transmission gearset. The invention concerns a transmission gearset of a three-shaft transmission, each with a transmission input shaft for the electric machine, and for the combustion engine, and an output shaft. For the connection or disconnection of the transmission input shaft of the electric machine while driving, the electric machine is used for the synchronization of the input shaft of the electric machine, and the created support torque at the combustion engine is determined, based on this support torque, to match a combustion engine torque and thus to compensate the support torque.

  • Publication number: 20190367035
    Abstract: A method for operating a drive-train having two drives, a drive output, a manual transmission having a planetary gearset and two independent load paths. From the first and second drives, torque can pass to the output via respective first and second paths. The two drives can be coupled to respective elements of the planetary gearset, and the transmission is coupled to a web gear. To start, when torque passes to the output first via a second path gear and thereafter via a first path gear whose ratio is different from that of the second path gear, then before changing from the second path to the first path, the torque passed at the web gear is changed such that if torque desired by the driver is unchanged, despite the change from the second to the first path, the torque acting at the output remains constant.

  • Publication number: 20190344654
    Abstract: A transmission having a main transmission and a splitter group, and including at least four spur gear planes formed with a countershaft and at least five shifting elements for engaging at least six gears between the transmission input and output shafts. When shifting between gears with the highest and the second-highest gear ratios, a shift occurs in the shifting elements associated with the splitter group but not in the shifting elements associated with the main transmission, whereas when shifting between gears with the lowest and second-lowest gear ratios, a shift occurs in the shifting elements associated with the main transmission but not in the shifting elements associated with the splitter group. An electric machine can be connected by a gearset, and depending on its shift position, the gearset acts as a pre-transmission ratio for the electric machine or as a superimposition transmission.

  • Publication number: 20190077246
    Abstract: A method of operating a vehicle having a hybrid drive, a transmission with shift elements, a drive output with a brake, a main transmission with input shafts, an output shaft and planetary gear sets (PG1, PG2). The main transmission has five gear planes. One shift element can connect a gear plane to an element of gear set (PG1) adjoining the main transmission. Another shift element couples a further element of gear set (PG1) either to the output shaft or a housing. An electric machine is permanently connected to an element of gear set (PG2). If, while driving with a transmission gear engaged, the drive output brake is engaged for a full brake application, a shift element of the transmission is first relieved by the electric machine and/or a brake assigned to one of the input shafts and then subsequently disengaged to decouple the combustion engine from the drive output.
