摘要： A transmission has an input shaft, first and second output shafts, and first and second planetary gear-set, connected together. The first output shaft is rotationally fixed to a first planetary gear-set second element, the second output shaft is rotationally fixed to a second planetary gear-set third element, a first planetary gear-set third element is rotationally fixed to a second planetary gear-set first element via a shaft, and a second planetary gear-set second element is secured to a rotationally fixed component. A first shift element blocks the third planetary gear-set by connecting third planetary gear-set elements in a rotationally fixed manner, a second shift element secures a third planetary gear-set first element to the rotationally fixed component, a third planetary gear-set second element is rotationally fixed to the first planetary gear-set first element via an intermediate shaft, and a third planetary gear-set third element is rotationally fixed to the input shaft.

摘要： An electric drive system has a group transmission with a main group and a range group with a planetary gear set. First and second input shafts of the main group are respectively coupled with first and second electric engines. An output shaft of the main group is coupled with a first element of the planetary gear set and a second element of the planetary gear set is coupled with an output drive shaft of the group transmission. Two idler wheels are disposed coaxially to the first input shaft and two further idler wheels are disposed coaxially to the second input shaft. The first and second input shafts are coupled with the output shaft via two fixed gears. A first fixed gear engages with the first and third idler wheels and a second fixed gear engages with the second and fourth idler wheels.

摘要： A method for operating a drivetrain of a motor vehicle includes elevating a system pressure acting on a plurality of shift elements (A, B, C, D, E, F) when one of at least one positively locking shift element (A, F) is closed in a force-locking-free state, increasing a torque output by a drive assembly (15) and then subsequently reducing the torque output by the drive assembly (15) while the system pressure is elevated by an intervention with the drive assembly (15), and reducing the system pressure after reducing the torque output by the drive assembly (15). The one of the at least one positively locking shift element (A, F) closed in the force-locking-free state or another one of the at least one positively locking shift element (A, F) is opened while the system pressure is elevated and the torque output by the drive assembly (15) changes.

摘要： A transmission for a motor vehicle includes a first planetary gear set with at least three central gears which are formed by a ring gear and two sun gears or by two ring gears and one sun gear. A second planetary gear set includes two central gears which are formed by one ring gear and one sun gear. One of the central gears of the second planetary gear set is constantly connected in a torque-proof manner to one of the central gears of the first planetary gear set. The one of the central gears of the first planetary gear set differs from and is arranged in a common gear set plane with the one of the central gears of the second planetary gear set. A carrier of the first planetary gear set is constantly connected in a torque-proof manner to a carrier of the second planetary gear set.

摘要： A method for operating a motor vehicle having a transmission (1), the method including closing a first number of shift elements and opening a second number of shift elements in each selected, force locking gear ratio of the transmission (1); closing one shift element less, and therefore opening one shift element more than in a selected, force locking gear ratio when a transmission (1) is not force locking in the sailing mode; adjusting the respectively closed and opened shift elements as a function of at least one operating condition of the motor vehicle in the sailing mode; and checking, at least on the basis of the rotational speed of the transmission input shaft (2), whether a previously closed, positively locking shift element (A, F) to be opened is actually opened in the sailing mode during adjusting of the respectively closed and opened shift elements.

摘要： A transmission includes a drive shaft, an output shaft, a housing, and a first through third planetary gear sets. Six shift elements include a first brake, a second brake, and first through fourth clutches. The shift elements are selectively actuated, by which ten forward gears and one reverse gear can be. Each planetary gear set features at least one sun gear, one planetary gear, one planetary carrier and one ring gear. The drive shaft and the output shaft are arranged in a manner axially offset to each other. The drive shaft is connectable to the sun gear of the third planetary gear set and the second brake through the first clutch, and is connectable to the planetary carrier of the third planetary gear set through the second clutch. The planetary carrier of the third planetary gear set is connected to the first brake.

摘要： A control system for a transmission includes first and second engagement devices and a controller. The first engagement device brings first dog teeth of a first member into engagement with second dog teeth of a second member to enable torque transmission therebetween. The second engagement device connects a third member and a fourth member while changing a torque transmitting capacity therebetween. The transmission establishes a predetermined gear stage by bringing into engagement the first engagement device and the second engagement device. The controller is configured to bring the first engagement device into engagement while reducing a torque transmitting capacity of the second engagement device and then to increase the torque transmitting capacity of the second engagement device, when shifting a gear stage from another gear stage established by bringing the first engagement device into disengagement while bringing the second engagement device into engagement to said predetermined gear stage.
