Abstract
This paper examines the possibility of characterizing vehicle classes through the use of a three degree-of-freedom linear model. Segregation is studied by evaluating the eigenvalue location in the complex domain for vehicle sideslip velocity, yaw rate, and roll angle. The influence of numerator dynamics on vehicle behaviour is studied. Vehicle class segregation is attempted through evaluation of the amplitude ratio of the frequency responses for sideslip velocity, yaw rate, and roll angle. Limited ability to definitively segregate vehicles into classes is found to exist.
