1. A vehicle communication system, having:
- a light emitting apparatus installed stationarily;
a modulator for modulating a light emitted from said light emitting apparatus by superimposing a predetermined signal thereon;
a light receiving apparatus installed on a vehicle side for receiving the light emitted from said light emitting apparatus and superimposed with the signal;
a decoder for reading out the signal superimposed on the light received by said light receiving apparatus; and
notifying means for notifying information based on a signal which is read out by said decoder.

Abstract
The present invention is directed to vehicle communication equipment capable of transferring information using light without adding new light emitting means, and further, between a stationary apparatus and a vehicle or between vehicles. A light emitted from a signal lamp (11) of a stationarily installed traffic signal (10) or a head lamp (35) or a tail lamp (36) of a vehicle (20) is superimposed with a signal by a modulator (13), the modulated light is received by a light receiving unit (21) of the vehicle (20) side, and the received modulated light is demodulated by a decoder (22) to be displayed on a display panel (24).
