Abstract

A localization system uses an auction-based cooperative localization method to determine local pose estimations or local pose state corrections. The auction-based cooperative localization method is triggered by receipt of relative position measurements by a member of a cooperative and is cooperatively processed by a bid winning member of the cooperative, where the cooperative refers to a collection of autonomous vehicles and passengers with location / position determinable devices that are in communication with each other for the purposes of sharing localization data, position data and the like.The bid winning member determines local pose estimations or local pose state corrections for itself and provides local pose estimations or local pose state corrections to the other members of the cooperative.

Description

technical field [0001] The present disclosure relates to an automated driving system including a vehicle and passengers. More specifically, the present disclosure relates to positioning methods for autonomous vehicles and passengers when Radio Navigation Satellite Service (RNSS) data is not available. Background technique [0002] Autonomous vehicles (AVs) exploring in unknown environments face many challenges in navigating planned or unplanned trajectories to reach their destinations. Many AV tasks rely on accurate knowledge of their position and orientation in space. Positioning is the process of precisely determining the location of an AV on the Earth's surface. AVs compute an estimate of their pose (ie, a combination of position and orientation) based on available absolute and relative measurements. Absolute measurements typically rely on the availability of Radio Navigation Satellite Service (RNSS) systems such as the Global Positioning System (GPS), GLONASS, Galileo...
