Abstract
Our investigations have shown that the current calibration procedures for dynamometers do not suffice to obtain a good conformity between different dynamometers.
As a criterion for dynamometer calibration, we use in two different ways the torque which is measured on the drive shaft of a test car. The static method yields the complete dynamometer characteristic: torque versus car speed.
The dynamic method uses the averaged time integral of the torque measured over a driving cycle. Both methods supplement each other.
In order to achieve a good reproducibility, a mechanized driver has been developed. Test results are discussed.
