Embodiment Construction

[0037] It is assumed that the method for assessing risk according to the invention is implemented in the first vehicle using measuring means and computing means and is controlled by a central processing unit for The central device that manages the electrical or electronic equipment of the vehicle.

[0038] This method is used to evaluate a first vehicle and at least one second vehicle traveling through an intersection, for example, for all vehicles traveling at a distance of less than 500 m from the intersection and on a carriageway providing access to said intersection collision risk between vehicles, the method comprising the following steps:

[0039] - a step of determining these corresponding positions of said first vehicle and each second vehicle, and different parameters enabling the provision of status information about each of said vehicles,

[0040] - a step of estimating the intention of the driver of the first vehicle and of each second vehicle as to whether to sto...

Abstract

The invention relates to a method for assessing the risk of a collision between a first vehicle approaching an intersection, the first vehicle being equipped with a measuring device and a computing device, and at least one second vehicle driving through the intersection. . The method according to the invention is mainly characterized in that it comprises the following steps: a step of determining the corresponding positions of said first vehicle and of each second vehicle; a step of estimating the intention of the driver of the vehicle; the need to stop the first vehicle and the need to stop each second vehicle is estimated from the results provided by the preceding two steps and the traffic rules applicable at said intersection and, a step of estimating the risk of the first vehicle colliding with each of the second vehicles.

Description

technical field [0001] The invention relates to a method for assessing the risk of collision at an intersection. Background technique [0002] Intersections are the most dangerous areas in the road network. For example, in 2004, 43% of accidents in Europe occurred at intersections. These are also particularly anxiety-inducing areas, especially for older drivers who sometimes have difficulty analyzing a scene and making appropriate decisions in the context of the situation. Accordingly, there is great interest in developing safety systems with the ability to accurately estimate collision risk at intersections. Such systems can be used to increase a driver's situational awareness as he approaches an intersection and then drives through it, and they can thus reduce the stress caused by the presence of said intersection and improve safety in these areas. [0003] The technical issues can be summarized as follows. Vehicles accumulate over time: [0004] - information about i...
