Transmission device having a plurality of shift elements

摘要

A drive engages a shaft (4) and, via at least one shaft (5, 6) of a transmission, an electric machine. An output can be connected to another shaft (9). During gear shifts, the shafts (4, 5, 6, 9) are couple such that the rotational speed of the shaft (5, 6), which can couple the electric machine when torque at the shaft (9) is equivalent to the torque of the electric machine, and is a product of the gear ratio between the shaft (5, 6) and the shaft (9) and the rotational speed of the shaft (9) or, when torque present at the shaft (9), is equal to the torque of the drive engine or electric machine, and is a sum of the product of the rotational speed of the shaft (4) and a first variable, and the product of the rotational speed of the shaft (9) and a second variable.

1. A transmission device (1) having a plurality of shift elements (A to G) which, in an engaged or a disengaged operating condition, being operatable for creating different gear ratios for the transmission device (1),
a drive engine (3) being coupleable at least with an input shaft (4), and an electric machine (7) being selectively coupleable with each of first and second another shafts (5, 6), while an output (8) being operationally connectable with an additional shaft (9), the input shaft (4) and at least one of the first and the second another shafts (5, 6) and the additional shaft (9) during at least an approximate traction force uninterrupted gear ratio change, starting from a currently engaged gear ratio (“1” to “R”), in a direction toward a target gear ratio (“1” to “R”), being operationally connected via the plurality of shift elements (A to G) which are involved in the gear ratio change such that a rotational speed (n5, n6) of at least one of the first and the second another shafts (5, 6), which are both selectively connectable with the electric machine (7), and when torque is present, an equivalent torque which is present at the additional shaft (9) corresponds to a product based on the gear ratio between the at least one of the first and the second another shafts (5, 6) and the additional shaft (9) and a rotational speed (n9) of the additional shaft (9), or when torque is present at the additional shaft (9), equivalent to the torque present at the drive engine (3) and present at the electric machine (7), is a product of the gear ratio between the one of the first and the second another shafts (5, 6) and the additional shaft (9) and the rotational speed (n9) of the additional shaft (9), or during presence of the torque of the drive engine (3) and torque at the electric machine (7) which is equivalent to the torque of the additional shaft (9), is a sum of a product of a rotational speed (n4) of the input shaft (4) and a first variable (V1) which equals a negative quotient of an initiated torque through the electric machine (7) and a torque initiated through the drive engine (3) and corresponds with a product resulting from the rotational speed (n9) of the additional shaft (9) and a second variable (V2), which equals a product resulting from the gear ratio between the input shaft (4) and the additional shaft (9) and the first variable (V1).
