摘要:
A hybrid drive arrangement for a vehicle with an internal combustion engine for driving, under engine power, and at least one electric machine (1), for electric driving, and with a double-clutch transmission. The electric machine (1) can be separated from the internal combustion engine by at least one separator clutch (3), in the form of a wet-operating, hydraulically actuated disk clutch. The outer disk carrier (4) of the separator clutch (3) and the outer disk carriers (5, 5A) of the two double clutches, of the double-clutch transmission, are connected and mounted on the transmission housing (6).
摘要:
A method implements a starting process for an internal combustion engine which has a drive unit and a transmission with at least two transmission input shafts and a multiple clutch device, in particular a double clutch device. During the starting process, the first gear is engaged in a first clutch of the multiple clutch device and is activated, while the second gear speed is engaged in a second clutch of the multiple clutch device but not activated. During the starting process, a current velocity is compared with a predefinable reference velocity, and when the reference velocity is reached a control unit causes the first clutch to be opened and thus causes the first gear to be deactivated while, in parallel with this, the second clutch is closed and the second gear is thus activated.

The invention relates to a method for operating a drive train (1) comprising an internal combustion engine (2), an electric motor (10) and an automatic transmission (11), in which, during an operating state with the electric motor (10) switched on and the internal combustion engine (2) switched off, the internal combustion engine (2) is engaged by a transmission of torque to the internal combustion engine (2), used to accelerate the internal combustion engine (2), being coupled in time with a downshift operation in the automatic transmission (11).

A drivetrain of a motor vehicle has an internal combustion engine, an electric motor, a transmission, and a torque converter with a converter bypass clutch. The drivetrain is controlled such that, during an electric operating mode in which the internal combustion engine is deactivated and the electric motor is activated, and/or during a recuperation operating mode in which the internal combustion engine is deactivated and the electric motor is operated as a generator, the converter bypass clutch is permanently closed, at least between shift processes of the transmission, in order to bypass the torque converter.

A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.

摘要:
A hybrid vehicle has an internal combustion engine (10) and a hybrid drive (12) that has an electric machine (11) and a transmission (13) having a drive output. During driving under purely internal combustion engine (10) power, only the internal combustion engine provides a drive torque at the drive output. During driving under purely electric motor power, only the electric machine (11) provides a drive torque at the drive output. During hybrid driving, the internal combustion engine (10) and the electric machine (11) each provide a drive torque at the drive output. The hybrid vehicle also has a pump unit (16, 20). The pump unit (16, 20) can be driven by the electric machine (11) of the hybrid drive (12).
摘要:
A method and a device control a hybrid vehicle drive. The device contains a multiplicity of control parameter sets having different recovery torques for a conversion control device which sets a recovery torque of the electric motor in an overrun phase, which recovery torques are assigned a respective driving mode indicator. A definition device is provided for defining a current driving mode indicator, as a result of which a control parameter set corresponding to the defined current driving mode indicator can be used to control the conversion control device in an overrun phase of the hybrid vehicle drive.
摘要:
A device and method for heating a positive crankcase ventilation system in a hybrid vehicle includes a ventilation device, provided on a crankcase, and a supercooling cycle for cooling power electronics for an electric motor of the hybrid vehicle. The ventilation device is heatable by way of the supercooling cycle in order to prevent icing of the ventilation device.
