Vehicle Dynamics Simulations on Road and Off-Road Surfaces – A Comparative Analysis

Abstract

Tyre models used in vehicle dynamics models are generally developed based on the behaviour of vehicles on specially constructed roads with prescribed adhesion characteristics. The behaviour of road and off-road vehicles on two different surfaces is different. In this study; on the basis of a tyre model that can be adapted both on the road and off-road, an approach is shown to the actual or encountered situations with simulated comparisons over standard vehicle dynamics manoeuvres. Matlab / Simulink is used as modelling and simulation environment.
