Abstract
The Anti-lock Braking System (ABS) fitted to modern passenger vehicles is
intended to provide reliable and efficient braking under critical road conditions
or in an emergency. However, the braking dynamics of a vehicle vary greatly
depending on the road surface. On an unsealed road surface an ABS equipped
vehicle will behave quite differently from vehicles without ABS. The braking
distance on gravel or snow covered roads is less for systems without ABS. In
this situation a snow or gravel wedge is responsible for an additional braking
effect with locked wheels. In an ABS system, the formation of the wedge results
in the unlocking of the brakes and the vehicle rolls over the wedge. Using a laser
slit line projected longitudinally on the wheel and observing deformat
