Directional control on the curved road using a double-point aiming model

Kazumasa Arai; Keiji Hanawa; Masahiro Kinoshita

The forward single-aiming model, which is now popularly used for an automatic controlled vehicle, often gives unsatisfactory traceability on a curved road with curvature changes. We have developed a new control system which employs a double-aiming (long and short distance) model and experimentally demonstrated a much improved traceability on a curved road consisting of R = 50 m multiple curves.
