Information Steering System for Autonomous Intelligent Low-Speed Vehicle

概要

Various types of low-speed vehicles have been developed for welfare and ecological purposes, some of which are equipped with autonomous locomotion functions. Although a number of technologies for safe autonomous locomotion have been developed, few researches have been conducted into technologies that provide the riders of such vehicles with a sense of security. Therefore, this research aims to develop a Human Machine Interface that provides a sense of security. Based on discussions held on information that would be useful for riders of intelligent low-speed vehicles, we constructed two prototype haptic interfaces termed as "Information Steering Systems," which provide advance notification of upcoming vehicle locomotion and alert notifications for surrounding pedestrians. We determined the characteristic parameters of the proposed system by conducting experiments using the first prototype interface with a powered wheelchair driving simulator. The operation of the proposed system was verified in two driving environments using the second prototype interface and a prototype intelligent powered wheelchair.
