Advanced Car Positioning and Bearing Method using Infrared Beacon

This paper describes the effectiveness of a novel positioning and bearing method using the existing infrared beacon. The infrared beacon is Japan’s original roadside infrastructure that provides 2 way communications between road and vehicles by using infrared-ray. The feature of the proposed method is to attach “the shadowing panel” on an onboard sensor of the infrared beacon and to have dead-reckoning means by using onboard sensors. The experimental results show the proposed method can offer accuracy of 40cm for head positioning, 152cm for lane positioning, and 0.1 degree/2km for bearing performance.
