Abstract
Large vehicles such as trucks and buses are known to have high and varying center-of-gravity heights. This fact causes large vehicles to have pronounced roll motions, which consequently affect the planar motions and stability of the vehicles, especially at high speeds. In this paper, lane-change experiments are conducted using a vehicle with and without a load to consider the effects of the varying c. g. height and vehicle velocity on the dynamic characteristics of a truck. Results are analyzed to determine how the velocity and amount of the load affect the peak values of the steering input and vehicle output and the output's delay with respect to the input.
