This paper presents a mathematical model for automotive stability study taking into account the influences of the inertias/s moment. It is also presents an experimental method for determination of the inertias/s moment for a vehicle related to the axis of a system which has the origin in its mass centre. The used procedure is based on the pendulous method which consists in the vehicle/s postponement and the measurement of the oscillations period around the suspension axle. The inertia moments of the tested vehicle are determined experimentally for three cases of loading, taking into account the load of a passenger case, three passengers case and five passengers case. The numerical results are determined based on a simplified mechanical model and a nonlinear differential mathematical model. It is investigated several cases of vehicle movement with different load and thus is highlighted the influence of different moments of inertia over the dynamic behaviour of the considerate vehicle.
