Abstract
The purpose of the study was to compare the important driving
characteristics of buses and personal vehicles and, more
specifically, their transient steering responses at constant
driving speed. The study sought to define these characteristics in
terms of time and frequency values which could be measured in
open-loop, driving tests.
Experimental results precede a theoretical treatment of driving
yaw (i.e., deviation from a straight path). A comparison of driving
parameters is related to frequency and transient response of the
two vehicle types. The results show that the primary differences
between the two are caused by differences in wheelbase and in
structural moments of inertia. These differences lead to quite
different processes in the bus from those of the automobile; they
consequently preclude a simple comparison of the two vehicle types
by use of the introduced response values.
