ABSTRACT:
Particularly in the case of electric motor vehicle drives using an hydrodynamic torque converter or appropriate coupling there is present the problem of proper and reliable operation of the vehicle condition control through the use of comparatively modest expenditure in equipment. This problem is solved by using a torque regulation with a torque control magnitude which is variable in accordance with controlled vehicle condition commands or an appropriate reference or set value, preferably through the use of a degree of filling control of the converter or the coupling as the positioning or adjusting element. When there is used an electric collector motor as the drive there is advantageously accomplished as a function of a threshold value of the degree of filling a change-over to an electrical field control.
