Abstract

A stability factor for force control is obtained theoretically. The stability factor is the ratio of the following two terms. One is the natural frequency of rotational motion of steering system around kingpin axis. The other is that of a vehicle around the vertical axis through its center of gravity. From the stability factor distribution of actual vehicles, its target value is proposed. To satisfy the value, a design method for steering system parameters on plots is also proposed. As a result, enough stable vehicles under force control can be designed theoretically and visually without numerical simulations.
