Abstract
The invention relates to a method for controlling, more particularly in a closed-loop manner, a test bench for a powertrain with a real transmission, the method including calculating a desired value of a control parameter, more particularly a desired rotational speed, at the transmission output of the real transmission by means of a model that represents the transmission and at least one further component, more particularly a shaft, of the output side of the powertrain as virtual components, on the basis of at least one measurement parameter, more particularly a rotational speed and/or a torque, measured on the powertrain; and controlling the test bench, more particularly a load machine, on the basis of the desired value.
