Abstract

Background. This paper considers a simplified autopilot problem - the development of a control system that solves the problems of path planning and tactical (real time) wheel platform control when solving a class of target tasks for driving a route specified as key points.
Materials and methods. Path planning and decision making of the presented strategy are based regarding tactical control on a dynamic reflexive graph, formed by Delaunay triangulation of road scene objects with its further translation by Voronoi diagram.
Results. Boundary conditions of the testing area, imitating conditions of a manufacturing plant/parking lot are shown. Safety criteria of performing maneuvers with both static and dynamic obstacles at the analyzed road scene are determined.
Conclusions. Series of model experiments for different test sites were made, showing effectiveness of proposed method. 

Key words
