Influence of vehicle characteristics on skidding risk

This paper represents an updating step of analyze the problem of friction of road vehicles. One of the greatest results of research into the role of friction in road safety is the 3rd criterion of Lamm. This criterion defines the road consistency of a road section on a curve, by comparison between the side friction factor assumed “fRA” and the side friction factor demanded “fRD”. the first one represents the friction force that road can provide to the vehicle; the second represents the force that the vehicle require to the road. These coefficient, in the hypothesis that the vehicle can be modeled as mass material point, are calculated. In this work it is shown that, an analysis that takes in account all the vehicle characteristics is most reliable.
