Vehicle Stability Boundary Analysis by Jacobian Matrix
In this section, we further figure out the stability boundary according to various steering, braking, or road friction conditions. As is analyzed above, the structures of phase portraits change with specific operation conditions. When the stable equilibrium point merges with the unstable saddle point, there is no stable region in the phase plane. We assume that if a stable equilibrium point exists, the corresponding vehicle motion is stable. Therefore, we could determine vehicle motion stability by the eigenvalues of the Jacobian matrix at each equilibrium point.the Jacobian matrix is given as
