[0028] The solutions of the prior art are not entirely satisfactory because the provided architecture involves "linear" processing of data (from disparates sensors and sources), some of which is potentially erroneous or Fault
With the architecture provided, handling of such erroneous or unreliable data is inevitable and can lead to unexpected actions
[0029] The solutions provided in the prior art are not well suited for the overly strong safety constraints used to maneuver autonomous vehicles

[0057] Depend on figure 1 The illustrated informatics architecture includes:
[0058] ● A first stage for generating data, said first stage comprising:
[0059] ○ Multiple on-board sensors (1 to 3);
[0060] o a plurality of connected components (11 to 13) in communication with external information sources;
[0061] A second stage for directly manipulating said data, said second stage comprising super-aware modules, each of said super-aware modules including an input port and a computer for signals coming from one or more sensors And via connected components, the computer is used to execute the object's hyperaware program, and the object's hyperaware program is used to implement the following functions:
[0062] ○ Perception functions, which enable the vehicle to interpret its own environment and perceive static or dynamic objects;
[0063] ○ positioning function, which enables the vehicle to determine its own position on the topographic map;
[0064] - A third stage for...

[0119] The second embodiment relates to the special case for determining the set lane of the vehicle.
[0120] This example concerns an autonomous vehicle that needs to be considered as level "OICA" 4 or 5, that is, with a level of autonomy where the driver is "out of the loop" (English term out of the loop)". The system needs to independently control and determine the movement of the car on any infrastructure and in any environment without driver intervention.
[0121] The following description refers to the insurance functional architecture of VEDECOM's autonomous vehicle "sur-système", which is designed on the existing vehicle platform to enhance the reliability and increase the functional safety of the vehicle, also ensuring The integrity of the operations and decision information employed by the intelligence of this "supersystem".
[0122] The insurance architecture of autonomous vehicles consistent with the present invention is formulated according to the following 4 d...

Abstract
The present invention relates to a system for steering an autonomous vehicle comprising a plurality of sensors (1 to 6) of different natures, calculators executing computer programs for determining items of information regarding delegated driving as a function of the data delivered by said sensors, characterized in that it furthermore comprises at least one arbitration module (15) comprising at least one calculator executing a computer program to decide the safest functional selection of one of said items of information regarding delegated driving as a function of a plurality of items of information calculated as a function: of dynamic data comprising part at least of the items of information consisting of: confidence levels (44) of each of said items of information of delegated driving, of the coherence (45) of variables associated with said delegated items of information o of the hardware and software reliability (46) of the components of said system of climatic and / or historical data comprising part at least of the items of information consisting of: the driving history of the vehicle (48), of environmental conditions (49), and of decision processings for the arbitration of a safe behaviour (47) of the steering.
Description
[0001] This application claims priority from French application serial number 1657337, filed 29 July 2016, the disclosure of which (text, drawings and claims) is hereby incorporated by reference. technical field [0002] The present invention relates to the field of autonomous vehicles, and more precisely to informatics devices for controlling autonomous vehicles. [0003] A vehicle is considered autonomous if it can move without the constant intervention and monitoring of an operator. According to the U.S. Department of Transportation, this means the sedan can operate without driver intervention in driving, accelerating or braking. However, the level of automation of the vehicle remains the most important factor. The National Highway Traffic Safety Administration therefore defines five levels of "automation": [0004] • Level 0: completely non-automated. The driver has total control over the main functions of the vehicle (engine, accelerator, steering, brakes) at any momen...
