Abstract
The present invention relates to a roller brake testing dynamometer (P) for vehicles whose braking forces are to be ascertained, wherein there is provided at least one roller (L) which is driven by way of a drive (A) in order in turn to drive a vehicle tire (R) bearing against the roller (L), wherein there is provided at least one braking force sensor (S) for ascertaining a braking force exerted on the roller (L) by the tire (R), and wherein there is provided an evaluation and control unit (E) to which the signals of the braking force sensor (S) can be fed. Furthermore, it is provided that the evaluation and control unit (E) is adapted on the basis of the signals from the braking force sensor (S) to ascertain the transition from static friction to sliding friction between the tire (R) and the roller (L) independently of the speed of rotation of the roller.
