This work presents the results obtained through the mathematical model with 10 degrees of freedom described in [G. Moscariello, On the mathematical modelling of complex dynamical systems an electrically operated vehicle, Math. Comput. Modelling (2007), doi:10.1016/j.mcm.2006.12.037] which relates to a motor vehicle activated through independent electric engines set in the rear wheels in the cases of motion with null steering angle (also in case of lateral forces for a limited period of time) and of motion with steered wheels. It is then explained how the model can determine both the vehicle’s motion parameters under different conditions and the external and internal constrained reactions. Finally, the analysis is devoted to the stabilizing effect of the lateral adherence forces, referred to as micro-slipping forces in [G. Moscariello, On the mathematical modelling of complex dynamical systems an electrically operated vehicle, Math. Comput. Modelling (2007), doi:10.1016/j.mcm.2006.12.037].
