Driving assistance method and device
First Claim
1. An assisting device for assisting with driving an automotive vehicle, said automotive vehicle including at least one illuminating device to emit a beam for illuminating a road scene in front of said automotive vehicle, the assisting device comprising:
- a variable transmission screen that is placed between said road scene and a driver of said automotive vehicle, the assisting device being configured to, when active, control a light emission of at least one light source of said at least one illuminating device and a transmission coefficient of said variable transmission screen, in relation to each other, with a pulsed signal, wherein the assisting device is configured to detect a vehicle equipped with another assisting device of a same type to the assisting device via inter-vehicle communication and to modify said pulsed signal to avoid antiphase and/or phase effects, when the assisting device detects such a vehicle, and the assisting device is configured to emit a recognition signal via the inter-vehicle communication when the vehicle equipped with the another assisting device of the same type, known as a detected vehicle, is detected.

- 14. A method for assisting with driving an automotive vehicle, said automotive vehicle including at least one illuminating device to emit a beam for illuminating a road scene in front of said automotive vehicle, and a variable transmission screen that is intended to be placed between said road scene and a driver of said automotive vehicle, the method comprising controlling, in relation to each other, a light emission of at least one light source of said at least one illuminating device and a transmission coefficient of said variable transmission screen, with a pulsed signal, wherein the method comprises detecting a vehicle implementing another method for assisting with driving the vehicle of a same type, via inter-vehicle communication, and modifying said pulsed signal so as to avoid antiphase and/or phase effects, when such a vehicle is detected, and the method comprises emitting a recognition signal via the inter-vehicle communication when the vehicle implementing the another method of the same type, known as a detected vehicle, is detected.
