Abstract: The invention relates to a method for localizing and enhancing a digital map through a motor vehicle. The method includes receiving a digital partial map representing an environment of the motor vehicle and capturing an image of the environment of the motor vehicle by a sensor arrangement of the motor vehicle. The motor vehicle is localized in the environment by comparing the received digital partial map with the image of the environment of the motor vehicle. The digital partial map is enhanced on the basis of the image of the environment, and the enhanced digital partial map and/or the image of the environment (U) is transmitted to a database for enhancing the digital map.

Abstract: A method for assisting in the driving of a vehicle on a fast road with carriageways separated by a safety rail in which the presence of the safety rail is detected is disclosed. The safety rail is modelled from measurements performed continuously by at least one laser scanner sensor mounted on the motor vehicle, with the determination of a confidence index associated with the detection by the laser scanner sensor, an automatic driving mode is activated when the confidence index ICONF is above a confidence threshold. This mode is maintained as long as a current confidence index associated with the detection is above the confidence threshold, and this mode is deactivated when the current confidence index passes below said confidence threshold. The density of traffic in front of the motor vehicle is estimated from images captured by an embedded camera.

Abstract: The invention relates to a method for determining an optimum speed (VOPT) to be adopted by a motor vehicle (1) when said motor vehicle (1) is approaching a traffic light (2). According to said method a first GLOSA-type on-board system (10) determines, upon receiving a message emitted by said traffic light (2), a total distance (DTL) of travel separating the motor vehicle (1) from the traffic light (2), then estimates the time necessary for the motor vehicle (1) to travel said total distance (DTL), and finally defines a recommended speed (VQ) based on the status of the traffic light (2) at the end of the estimated time. The method is characterised in that it also uses at least one speed limitation produced via a second system (12; 13) on board said motor vehicle such as to determine said recommended speed (VQ) and/or said optimum speed (VQPT).
