  Visible light communication (VLC) is a promising Optical Wireless
Communications (OWC) scheme that is demonstrated to provide secure,
line-of-sight (LoS), and short-distance vehicle-to-vehicle (V2V) and
vehicle-to-infrastructure(V2I) communications. Recently, automated driving
applications, supported by V2I links are proposed to increase the reliability
of the autonomous vehicles. To this regard, we propose a VLCbased V2I scheme to
increase the V2I communication redundancy of autonomous valet parking (AVP)
applications, through jam-free and location-based characteristics of VLC. In
this paper, we demonstrate a novel architecture to support indoor
parking-garage online-map update with vehicle on-board data transmissions and
location-based map update dissemination through bidirectional VLC
communications. The proposed system yields error-free LoS transmissions with
Direct Current Biased Optical OFDM (DCO-OFDM) up to 33 m transmitter-receiver
distance enabling vehicle CAN Bus data, infrastructure camera video, and LIDAR
point cloud data sharing in an indoor parking garage.
