AbstractActive safety is one of the most important factors determining the development of modern automobiles. Current vehicles are getting more and more safe, at the same time ensuring better performance. Road conditions during ride are varied and changing, just as the distribution of mass on vehicle axles depending on load distribution may change. A typical passenger car has four wheels, by means of which longitudinal and lateral forces are transferred to the road. In this article, the influence of the kind of surface and weather conditions on limit forces on vehicle wheels is shown. For this purpose, Dynamic Square Method was used (DSM). It allows to establish maximum longitudinal forces on vehicle wheels for a given lateral acceleration. DSM ensures acquiring characteristics in the form of isolines with constant values of lateral acceleration obtained for specific values of longitudinal forces on road wheels. Characteristics are within a field limited by a square, hence the name of the method. Analyzing the obtained characteristics, one can determine how changing the value of adhesion coefficient influences values of longitudinal forces on vehicle wheels.
