The Advantages of a Simple Approach Modelling Heavy Vehicle Handling

A generic articulated heavy vehicle model, applied to a tractor semi trailer combination is modelled on an approach characterised by simplicity. Yet, the handling characteristics accuracy serves well within the frequency domain of interest.

Possessing the capacity of performing in real time simulation up to the limits of yaw and roll stability, its simplicity derives advantages offering effective parameter variation possibilities at an elevated educational level. As an example, better understanding of the expected wheel angle deviation from the current wheel spindle angle is achieved through an extension of the model.

Validated against field experiments of lane change manoeuvring under high friction conditions up to the limit of roll stability, it also compan?s well against a more complex computer model.
