Simulation of vehicle motion dynamics plays significant role when discussing active safety. In case of curvilinear motion of vehicle cornering stiffness of tyre is one of the parameters of automobile that are necessary to perform the simulation. There are also needed inertial parameters of vehicle such as mass of vehicle, mass moments of inertia or location of the center of gravity. To perform simulations of curvilinear motion of vehicle it is not always necessary to apply complicated models. In many papers simplified single track model (bicycle model) is used. Authors of the article apply this model to perform simulation of double lane change maneuver of automobile. Side slip characteristics are built on the basis of road tests using Pacejka’s Magic Formula equation. They were obtained for front and rear axle on the basis of road test measurements for fixed value of normal load of axle. To make it possible to show the influence of vertical motion dynamics of curvilinear motion, single track model was extended to include the influence of the changes of normal forces interacting between tyres and road. It was necessary to propose a family of side slip characteristics in dependence on dynamic changes of normal load of axle, which was obtained in each step of simulation as a result of kinematic extortion.
