Authors Abstract
Content
The subject of offtracking has been considered as a low speed phenomenon, amenable to analysis via small mechanical models or straightforward calculations. This paper views offtracking from a high speed as well as a low speed vantage point. A mathematical model with one degree of freedom is used to show that there is a speed, well within the routine driving range and independent of radius, at which there will be no offtracking in a steady turn. At higher speeds the trailer will track outside the steady turn circle, and at lower speeds the trailer will track inside the steady turn circle. The analysis indicates similar behavior in a lane change maneuver - small offtracking was found to occur at the steady turn zero-off tracking speed, and larger off tracking was found to occur at both higher and lower speeds.
