  • a) estimating the path (T) of the motor vehicle along a stretch of road;

    b) defining an area of detection of obstacles (DECT) in the stretch of road;

    c) determining obstacles in the area of detection of obstacles (DECT);

    d) identifying a main obstacle from among the obstacles detected;

    e) determining a level of risk associated to a potential collision of the motor vehicle with the main obstacle; and

    f) warning the driver on the basis of the level of risk determined,.wherein determining a level of risk associated to a potential collision of the motor vehicle with the main obstacle comprises determining a first level of risk or a second level of risk; and

    wherein warning the driver on the basis of the level of risk determined comprises generating, when the level of risk determined corresponds to the first level of risk, a signal or message indicating to the user to reduce the speed of the motor vehicle, or generating, when the level of risk determined corresponds to the second level of risk, a signal or a message indicating to the user to apply the brakes and/or act on the steering wheel so as to avoid the road obstacle.
