COMMUNICATION SYSTEM AND METHOD FOR A VEHICLE

The present invention concerns a communication method and system for a vehicle, the system comprising:- an emitter (11) comprisingi. a light emitting device (111) comprising multiple sources of light aligned with one another, andii. a light control system (112) configured for controlling the light emitting device (111);- a receiver (12) comprisingi. a light detector (121), andii. a processing unit (122) configured for processing a signal outputted by the light detector (121);wherein:- one among the emitter (11) and receiver (12) is configured for being installed on-board the vehicle (3) and the other one on a road or track (2) over which the vehicle (3) is configured to move so that the light detector (121) is able to face the multiple light sources one after another during a motion of the vehicle (3) on said road or track (2);- the light control system (112) is configured for encoding information in the light emitted by the light emitting device (111) and the processing unit (122) is configured for decoding said information from the signal outputted by the light detector (121).
