A Clarification of Relationship Steering Force and Yaw Characteristics to Line Traceability in Small Steering Angle

Abstract

When driving along a straight roadway, a driver regularly makes minute steering adjustments in order to maintain the vehicle’s position within the driving lane. This paper clarifies the quantitative relationship of several steering characteristics in this scenario for accurate line tracing. In this research, the first step was to investigate the driver’s behavior when driving along a straight roadway. Then, a driver model consisting of this behavior was created and underwent driving simulations to hypothesize the relationship between line traceability, steering force and vehicle yaw characteristics. Finally, this hypothesis was tested and verified using an actual driving simulator.
