Visible light communication apparatus for vehicle, system and method for vehicular communication inside tunnel using visible light communication
A visible light communication apparatus for a vehicle is provided. The visible light communication apparatus for the vehicle includes a vehicle optical receiver for receiving a visible light signal including a tunnel light node ID, a front passing vehicle node ID, and tunnel environment data, from a tunnel light and converting the visible light signal to an electric signal; and a vehicular visible light emitting diode unit arranged to face the optical receiver for converting vehicle speed and location information calculated by counting tunnel light node IDs received over a certain time, to a visible light signal and sending the visible light signal to the tunnel light. Using the vehicular visible light communication apparatus and the tunnel light having the visible light communication function, an efficient vehicular communication system can be built in the tunnel.
