A method is described for operating a parallel hybrid device train (1) of a vehicle having an internal combustion engine (2), an electric engine (3) and an output (5) wherein the electric engine (3) is disposed in the power train between the output (5) and the internal combustion engine (2) and both between the internal combustion engine (2) and the electric engine (3) and between the electric engine (3) and the output (5) is respectively provided a frictionally engaged shifting element (7, 8). In addition, a nominal output torque abutting on the output (5) can be adjusted according to the transmitting capacity of the first shifting element (8) located between the electric engine (3) and the output (5). According to the invention, the transmitting capacity of the first shifting element (8) is adjusted under control according to the nominal input torque required so that the first shifting element (8) has a transmitting capacity needed for producing the nominal output torque on the output (5). Furthermore, an input rotational speed of the electric engine (3) is adjusted under regulation during a starting process of the internal combustion engine (2) in order to keep the first shifting element in slip operation at least during the starting process of the internal combustion engine (2) and to produce the nominal output torque on the output (5).

A method for operating a parallel hybrid powertrain (1) of a motor vehicle with multiple drive units (2, 3) and with a single output side (5) is described. At least one internal combustion engine (2) and one electric motor (3) are provided and the at least one electric motor (3) is arranged in the powertrain between the output (5) and the at least one internal combustion engine (2). A first friction-locking shifting element (7) is provided between the internal combustion engine (2) and the electric motor (3), while a coupling element (8A) with rotational speed dependent recognition and at least one second friction-locking shifting element (30) are arranged between the electric motor (3) and the output side (5). A target output torque to be applied at the output (5) is a function of the power transmission capacity of the second shifting element (30). The power transmission capacity of the second shifting element (30) is controlled as a function of the required target output torque (m_fahr_soll) so that the second shifting element (30) has the power transmission capacity required for achieving the target output torque (m_fahr_soll) at the output (5). A target slip specification (s_30_soll) of the second shifting element (30) is controlled at least as a function of the target-drive torque by means of the target drive torque (m_2_soll, m_3_soll) to be produced and are converted with a closed loop control as a function of a further operating state parameter of the parallel hybrid powertrain by the drive units (2, 3).

A double clutch transmission of countershaft design having a central shaft and a concentric hollow transmission shaft, one countershaft, and two power-shift elements. Two hollow shafts are disposed on the countershaft coaxially to the countershaft, each of which can be fixed, via one shift device, to the countershaft, and to which at least two gearwheels are fixed. A further hollow shaft is coaxially provided on either the central or hollow transmission shafts and can be connected, via a shift device, to the central or hollow transmission shaft, and to which at least two further gearwheels of the gear stages are fixed. At least three transmission ratios are possible by engaging three of the gear stages on the shift-element side into the power flow, thereby enabling one transmission ratio to be at least partially implemented by a respective sole engagement on the shift-element side into the power flow.

A dual clutch transmission designed as a reduction gearing which has concentric central and hollow transmission shafts, exactly one layshaft, and two power shift elements. A hollow shaft is provided coaxially on the layshaft, which can be rotatably fixed to the layshaft, via one shift device, and to which at least two gears of the gear stages are rotatably fixed. A further hollow shaft is provided coaxially on either the central or the hollow transmission shaft, which can be connected, via one of the shift devices, with the central or the hollow transmission shaft and to which at least two further gears of the gear stages are rotatably fixed. At least three transmission ratios are obtainable as a result of engaging the shift element into the power flow in three of the gear stages, by which one transmission ratio results from engaging only one shift element into the power flow.

A method for determining conditions of a hybrid drive train of a motor vehicle. The method determines, the actual conditions (1, 2, 3, 4, 5, 6, 7, 8) of the drive train from predetermined condition parameters of the actuating device of the hybrid control. The condition parameters include whether or not a flow of force is present between a combustion engine (VM) and an electrical engine (EM), whether or not the combustion engine (VM) is operating, and whether or not a flow of force to the output is present.

The electric engine being located in the power drive between the output and the internal combustion engine. A second shifting element is located between the internal combustion engine and the electric engine and a first shifting element between the electric engine and the output. Output torque driving the output can be adjusted according to the transmitting capacities of the first and second shifting elements and according to the input torque of the electric engine and/or internal combustion engine. These adjustments are corrected according to standards derived from divergences found in parameters during operation of the drive train.
