Abstract:
1. A method for communication between an emitting motor vehicle (Ve) and at least one target, the emitting motor vehicle (Ve) including at least one light device, the method comprising the following step: automatically modulating a light signal emitted by the at least one light device to provide a modulated light signal (S) for a communication between the emitting motor vehicle (Ve) and the at least one target, wherein said modulated light signal comprises a train of periodic light pulses, a number of said periodic light pulses being between 1 and 10 per pulse train; the at least one light device being chosen from: a lighting device, a daytime running light (DRL), and a position light; triggering said automatic modulating step in response to an activation of a manual control device by an operator of the emitting motor vehicle (Ve); wherein the modulated light signal (S) is arranged to be perceptible to the human eye; wherein the at least one light device is arranged to fulfill a predetermined regulatory photometric function, said photometric function being a headlamp function chosen from: a high beam; a low beam; a DRL light (Daytime Running Light); or a fog beam; and the modulated light signal corresponding to the modulation of the predetermined regulatory photometric function, wherein the predetermined regulatory photometric function comprises a road lighting function; wherein a light intensity of said light signal is substantially equal to that of said road lighting function produced by said at least one light device before said light signal is modulated and said modulated light signal causes said at least one light device to provide a modulated light intensity that is greater than said light intensity in response to said triggering step; wherein a time between two consecutive pulses is between 100 ms and 300 ms.
