Optimal Stability of Vehicle Control

Using steering stability theory, the way of optimization of vehicle parameters is given in this paper. A suitable mechanical model of vehicle movement including its basic characteristics is defined. Then a methodology of qualitative estimate of control stability is given through:

• stability conditions,
• reaction time at disturbances and
• vehicle steering.

On the basis of the analysis performed by the authors the optimal criteria of control stability are defined. The system environment - vehicle - driver (E-D-V) is considered.

To illustrate the given methodologies the influence of the mass on the steering stability is given in the paper.
