PROBLEM TO BE SOLVED: To provide a technique by which visible light communication between vehicles can be established on a road with poor visibility.SOLUTION: A vehicle communication device 1 comprises, as constitutions for transmitting information, a headlamp 3 installed on a vehicle 2 and a signal transmission device 10 which makes visible light V with a communication signal superimposed thereon to be emitted from the headlamp 3. The signal transmission device 10 executes signal superimposition processing of superimposing a communication signal on the visible light V emitted from the headlamp 3 when a road reflecting mirror 90 is within an arrival range of the visible light V emitted from the headlamp 3.
【課題】見通しの悪い道路における車両間での可視光通信を確立することを可能とする技術を実現する。【解決手段】車両用通信装置1は、情報を送信するための構成として、車両2に設けられた前照灯3と、通信信号が重畳された可視光Vを前照灯3から照射させる信号送信装置10とを備える。信号送信装置10は、前照灯3から照射される可視光Vの到達範囲内に道路反射鏡90が存在する場合に、前照灯3から照射される可視光Vに通信信号を重畳する信号重畳処理を実行する。【選択図】図1
