4.8.4.2 Checking ASR / ASD
A check of the ASR or ASD simulates the situation of a „gripping“ tire and a slipping tire. For
example, one tire of the vehicle is on a dry surface and the other tire is on an ice plate.
During the check, one roller set is blocked (dry surface), and the other runs freely (ice plate). If
the ASR (or ASD) is functioning during the check, it is possible to drive the vehicle out of the
test stand.
