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.
reaction time at disturbances and
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.
