Abstract
Recent applied research studies in vehicle handling have emphasized large commercial vehicles. Among the results to date are a set of nonlinear equations to model the lateral and longitudinal handling dynamics of an intercity bus. These equations were implemented as a digital simulation for analysis of vehicle response and performance with various steering and braking inputs. Concurrent full-scale tests with an instrumented vehicle served to verify the simulation results for both perturbation and large amplitude motions. This paper describes the bus, the analytical model, and the simulation.
