For the motor unit formed by an electric motor 22 is a vertical line n 22 , for the first motor unit formed by an internal combustion engine 14 is a vertical angle 14 for the wave 50 is a vertical straight n 50 , for the output shaft 88 is a vertical straight n 88 , for the second brake unit 84 is a vertical line n 84 and for the motor unit formed by an electric motor 20 a vertical straight line n 20 is plotted, resulting in distances of the straight lines n 14 , n 20 , n 22 , n 50 , n 84 , n 88 from present gear ratios. To represent speeds, known speeds are associated with bars n 40 , n 44 , where bar n 40 is the speeds of the first planetary set 40 and the bar n 44 the speeds of the third planetary gear set 44 represents. The second brake unit 84 is closed, so that an intersection of the bar n 44 with the line n 84 is at zero.

Im dargestellten Vorwärtsfahrmodus liefert die erste Motoreinheit 14 ein Drehmoment M14, welches als auf den Balken n40 vertikal nach oben wirkende Kraft dargestellt werden kann.

Das Abtriebsdrehmoment M88 wirkt mit einem Drehmoment M74 bzw. mit einer in einem Schnittpunkt der Balken n40, n44 auf den Balken n40. Um ein Gleichgewicht zu erreichen, wird die Motoreinheit 20 als Generator betrieben und wirkt mit einem Drehmoment M20 bzw. mit einer Last an einem dem Schnittpunkt gegenüberliegenden Ende des Balkens n40 nach unten. Eine aus dem Generatorbetrieb der Motoreinheit 20 resultierende Energie wird der Motoreinheit 22 zugeführt und in ein Drehmoment M22 umgewandelt, das auf den Balken n40 im Schnittpunkt nach oben wirkt und eine Unterstützung desselben bewirkt.In the illustrated forward drive mode, the first engine unit provides 14 a torque M 14 , which can be represented as acting on the bar n 40 vertically upward force. An output torque M 88 can be represented as a load acting down on the bar n 44 . The output torque M 88 acts with a torque M 74 or at an intersection point of the bar n 40 , n 44 on the bar n 40th To achieve a balance, the engine unit 20 operated as a generator and acts with a torque M 20 or with a load at an opposite end of the intersection of the bar n 40 down. One from the generator operation of the motor unit 20 resulting energy is the motor unit 22 supplied and converted into a torque M 22 , which acts on the bar n 40 in the intersection point upwards and causes a support thereof.

Beide Motoreinheiten 20, 22 werden als Motor betrieben und dienen zur Umwandlung elektrischer Energie in Drehmomente M20', M22'.The first power input 12 or the first motor unit 14 is by means of the blocking unit 24a locked and the first motor unit 14 is at a standstill or has a speed of zero, as can be seen on a bar n 40 '. The lock unit 24a serves as a support, so that in addition to the switchable in their direction of rotation motor unit 22 also the engine unit 20 can be used to support or to build up an output torque M 88 'in the reverse drive mode, without having to be able to switch over it.
