Abstract
A method and apparatus for adjusting the torque output of a power train of a motor vehicle. An engine is connected to the input end of a continuously variable belt-type transmission. The output end of the belt-type transmission is operably connected to the drivable wheels of a motor vehicle. Open-loop torque control for the power train of the motor vehicle is effected based on specific operating states of the power train and the mechanical tension acting on the belt of the continuously variable belt-type transmission.

12. A device for adjusting a torque output of a power train of a motor vehicle, said device comprising:
-
an engine;
a continuously variable belt-type transmission comprising a belt and two sheaves operably connected to said driving machine;
drivable wheels operably connected to said transmission; and
wherein said device adjusts the tension acting on said belt to cause a power loss in the power train based upon specifiable operating states of the power train.
