Vehicle lighting system comprising means for emitting a luminous signal coded at very high frequency

A vehicle comprising a lighting system, the lighting system includes an optical assembly including a front left lighting device and a front right lighting device each able to project a lighting beam, a means for emitting a high-frequency coded luminous signal outside the vehicle with photonic emitters, and a means for receiving such a luminous signal arriving from outside the vehicle with photonic receivers,

• a luminous device intended to be arranged on the vehicle between the lighting devices, the luminous device includes at least one portion of the set of photonic emitters and at least one portion of the set of photonic receivers, and in that the lighting system includes obstacle detection means, and means for decoding a luminous signal received by one of the photonic receivers of the luminous device, able to provide at least one value representing a time shift between, on the one hand, the luminous signal received by the photonic receiver of the luminous device and, on the other hand, a luminous signal sent by at least one of the photonic emitters of the luminous device to the obstacle detection means, wherein the front left lighting device is arranged on a front left portion of the vehicle, the front right lighting device is arranged on a front right portion of the vehicle, and the luminous device is arranged on a front face of the vehicle between the front left lighting device and the front right lighting device.
