중형버스의 차선변경시 조안특성에 관한 연구

The handling characteristics of a medium bus during a single lane change manoeuvre are investigated through computer simulation using DADS. Dynamic full model of the vehicle is established using tires, shock absorbers, leaf springs, sprung mass, and unsprung masses. A driver is assumed to steer the vehicle along a prescribed path which was obtained from field tests. He was modeled as PID controller in the simulation. The factors influencing the handling charateristics of the vehicle are studied.
