Embodiment Construction

[0051] figure 1 A motor vehicle, generally indicated at 10 , is shown diagrammatically. The motor vehicle 10 has a drive train 12 comprising, in the present case, an electric machine 14 for providing drive power and an internal combustion engine 16 . The drive train 12 is used to drive driven wheels 18L, 18R of the motor vehicle 10 and is configured as a parallel hybrid drive train in the form shown here.

[0052] The internal combustion engine 16 is connected or can be connected to the electric machine 14 via a crankshaft 20, the internal combustion engine 16 and the electric machine 14 provide a torque t on an output shaft 22, which rotates at an adjustable speed rotate. The output shaft 22 is connected or can be connected to a transmission unit 24 in order to transmit the torque t to the driven wheels 18R, 18L. In the present case, the crankshaft 20 and the output shaft 22 each have a clutch 26 , 28 in order to connect the internal combustion engine 16 to the electric ma...
