Sign to vehicle identification system
First Claim
1. A system comprising:
- a sign comprising sign communication information;
a marker positioned at a predetermined location relative to the sign, wherein the marker comprises retroreflective material defining marker communication information; and
a vehicle information system comprising a light source configured to emit light to the marker, a reader configured to receive marker communication information, and a processor configured;
to generate output information based on the received marker communication information and positional information related to at least one of a position of the autonomous vehicle or the predetermined location of the marker;
send, to an internet-based information storage system, the generated output information that is based on the marker communication information and the positional information;
receive additional information relating to the generated output information; and
in response to determining that the received marker communication information is relevant to the autonomous vehicle, control a function of the autonomous vehicle based at least in part on the additional information received from the internet-based information storage system that relates to the generated output information, wherein the received marker communication information comprises retroreflected light from the light source that is retroreflected by the retroreflective material.

Abstract
Disclosed is an identification system to improve safety on roads and allow for the driver or for the vehicle itself, if it is autonomous or semi-autonomous, to have readable and useful information about road signs, roadways, and adjacent roadway information. The disclosed identification system comprises a marker with marker communication information that can be read by a vehicle information system to provide information to the vehicle. Information that the marker communication information may convey would allow the vehicle information system to detect or recognize, or both detect and recognize critical road sign, roadway information, and adjacent roadway information. Then, the vehicle information system could respond to the information received from the marker communication information.
