A Measurement Standard for Vehicle Localization and Its ISO-Compliant Measurement Uncertainty Evaluation

Abstract

A fully autonomous road traffic has already been desired for years but could not be realized until now. Aside from the capability of the vehicles to communicate with each other (C2C) or with the infrastructure (C2I), the main obstacle for the realization of a fully autonomous traffic is a sufficiently accurate and reliable localization. The localization of vehicles, i.e., the real-time measurement of the position of moving objects, is still a challenging task, as each vehicle has to be localized at every time and at any place of the road network with a high accuracy and availability. Since fully autonomous traffic is a safety-relevant application, a proof of safety for all safety-relevant components is indispensable. Therefore, the measurement quality of the applied measurement devices has to be verified. For a determination of the accuracy and availability performance of localization systems, an accredited testing and calibration laboratory for vehicle localization is necessary, which does not exist yet. Such a laboratory has to provide a measurement standard for vehicle position measurements and an uncertainty evaluation for the reference value according to standards. This paper suggests a measurement standard for automotive vehicle localization and its measurement uncertainty evaluation according to the International Organization for Standardization Guide to the Expression of Uncertainty in Measurement.
