A Study on Pitch Characteristic to Reduce Line Trace Deviation 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. In the research of the previous report, the quantitative relationship of several steering characteristics in this scenario was clarified for accurate line tracing. However, it was found that the deviation of the tracing line by trials was not small at the same time. This paper clarifies one of the factors of the deviation and its improvement by adding minute pitching motion to the vehicle in proportion to the steering angle.
