DISPOSITIF AUTOMOTEUR ET PROCÉDÉ DE COMMANDE DE DÉPLACEMENT ET PROGRAMME DE COMMANDE DE DÉPLACEMENT DU DISPOSITIF AUTOMOTEUR

摘要

A self-propelled device capable of autonomously traveling on the left side or right side of a virtual path, a method of controlling traveling of the self-propelled device, and a computer program of controlling traveling of the self-propelled device are provided. The method and the computer program each include: a first step of estimating the position of a self-propelled device 100; a second step of determining the intersection point N of a virtual path 2 and a straight line, the virtual path connecting a start point A and a goal point B, and the straight line passing through the position of the self-propelled device 100 and which is orthogonal to the virtual path 2; a third step of determining an offset reference point Tp between the intersection point N and the goal point B on the virtual path 2; a fourth step of determining at least each of offset points Toft1 and Toft2 at an offset on the corresponding one of the goal point B side and the start point A side of the offset reference point Tp on the virtual path 2; a fifth step of determining at least target points ToftL and ToftR reached by rotating the offset points Toft1 and Toft2 by 90° about the offset reference point Tp in one of the anticlockwise direction and the clockwise direction; and a sixth step of causing the self-propelled device to travel toward the target points ToftL and ToftR.
