Embodiment Construction

[0030] figure 1 A schematic diagram of a motor vehicle 1 with a hybrid drive according to the invention is shown. For this purpose, the motor vehicle 1 also includes, in addition to the usual internal combustion engine 2 , a traction electric machine 3 which can be operated as a motor or as a generator. These two prime movers can be connected through the separation clutch 4 .

[0031] The resulting drive energy, ie the tractive force, is transmitted via the transmission 5 with the starting clutch 6 to the drive shaft 7 .

[0032] The various components in the powertrain of the motor vehicle 1 are controlled by a controller, wherein in the present case not only the internal combustion engine 2 is assigned a controller 8 but also the electric machine 3 is assigned a controller 9 . The transmission 5 is controlled by a transmission controller 10 .

[0033] In the present case, the controller 8 forms the main controller for the prime mover of the motor vehicle 1 . Of course, a...

Abstract

The invention relates to a motor vehicle (1) with a hybrid drive, comprising: an internal combustion engine (2); an electric machine (3), which can be operated as a motor and can be used to start the internal combustion engine (2) ); a control device (11); and a starter (13) operable to start the internal combustion engine (2), wherein, when the internal combustion engine (2) is about to be started, the control device (11) is designed to on the basis of at least one operating parameter (22, 23) of the motor vehicle (1) describing a driving dynamics requirement and / or a torque requirement of the hybrid drive and / or a controller of the motor vehicle (1) ( 10) to select the electric motor (3) and / or the starter (13) to start the internal combustion engine (2).

Description

technical field [0001] The invention relates to a motor vehicle with a hybrid drive comprising: an internal combustion engine; an electric machine operable as a motor and which can be used to start the internal combustion engine; a control device; and a control device which can be used to start the internal combustion engine Engine starter. Furthermore, the invention relates to a method for selecting an electric machine and / or a starter for starting an internal combustion engine in a motor vehicle with a hybrid drive. Background technique [0002] Motor vehicles with a hybrid drive, which include not only an internal combustion engine but also a traction motor, are generally known in the prior art and are advantageous due to their energy-efficient driving style. In contrast to motor vehicles that are only equipped with an internal combustion engine, motor vehicles with hybrid drives are known in which the internal combustion engine is started by means of a drag start and / or...
