Definitions
- the present invention relates to the general field of semi-autonomous or autonomous motorized road vehicles, and is more particularly interested in securing the movement control of this type of vehicle near a level crossing.
- ADAS advanced driver assistance systems
- ADAS advanced driver assistance systems
- systems carrying out, in the driver's place, lateral control and/or longitudinal control of the vehicle, or at least alerting the driver of a potentially dangerous situation to enable him to react in time. It is also planned to make motor vehicles completely autonomous, that is to say without a driver.
- the driving assistance systems thus have the general function of alerting the driver of a situation requiring vigilance and/or of defining the trajectory that the vehicle must follow to arrive at a given destination, and thereby allowing following control of the steering, braking and/or acceleration control bodies of the vehicle, so that this trajectory is effectively followed automatically.
- the trajectory must be understood here in its mathematical definition, that is to say as being the set of successive positions which must be occupied by the vehicle over time.
- driver assistance systems must define not only the path to take, but also the speed profile to respect.
- At least one detection module which detects a lot of information on the immediate environment of the vehicle (presence of obstacles such as pedestrians, cycles or other motorized vehicles, road signs, road configuration , ground marking lines, etc.), coming from one or more environmental perception sensors fitted to the vehicle, such as cameras, radars and/or lidars, as well as information linked to the vehicle itself, such as its speed, its acceleration, its position given for example by a GPS type navigation system.
- the ADAS systems make it possible to temporarily delegate driving in certain traffic conditions, and can be activated or not, depending on the driver's choice.
- the notion of driver no longer exists, and the systems on board the vehicle must make it possible to perceive the environment, analyze the dangers, and decide on the trajectories to follow to reach a destination. , and carry out all necessary longitudinal and lateral checks.
- level crossings (corresponding in the following to a crossing of a railway line with a road) represent areas with a high risk of accidents and are therefore part of the road situations that a Embedded control system should be able to handle it.

- the on-board system 43 is configured to extract from said at least one message received from the fixed infrastructure 10, one or more pieces of information contained in this message, so that the processing module 47 can decide on a management strategy to adopt in controlling the movement of the vehicle 4.
- the processing module 47 is advantageously configured to determine, on the basis of information(s) extracted from said at least one message received, whether the sensor(s) (s) exteroceptive(s) 44 and/or the associated detection module(s) 45 and/or the processing module 47 are capable of managing crossing the level crossing.
- the expression “capacity” must be understood to mean that the on-board movement control system 43 has been designed to know how to manage one or more categories of level crossing and/or to perceive and detect one or more components of the system. signaling and/or protection associated with the level crossing, and/or that the components of this signaling system are operational.

- the processing module 47 can decide on the inability of the system 43 to manage a safe crossing of a level crossing if it is informed, according to the message(s) ( s) received, that it is a level crossing of category PN SAL 0 then that the system 43 was designed to manage only level crossings of category PN SAL 2, or if it is informed of a poor visibility index associated with a component, or if no indication relating to marking lines on the ground delimiting entry, exit, and/or lateral boundaries is contained in the message(s) received.
- the determination of the capacity/incapacity can also be carried out on the basis of the type of decking of the level crossing, and/or on the distance between an entry barrier and an exit barrier, Other rules allowing the processing module 47 to determine the capacity or non-capacity to manage a crossing can of course be followed without departing from the scope of the invention.
- the processing module 47 is advantageously configured to determine, always on the basis of information(s) extracted from said at least a message received, if the vehicle 4 it equips is indeed authorized to cross the level crossing (even in cases where there is no train whose passage is imminent or in progress).
- the notion of authorization is distinct from the notion of capacity seen previously, and is linked here to regulatory prohibitions in the highway code, particularly in terms of dimensions and/or weight of the vehicle 4, or even what could be transported by this vehicle 4.
- the determination of the authorization/prohibition can in particular be carried out on the basis of information relating to certain traffic signs upstream of the level crossing, and/or an indication of the presence of a gauge gantry. associated with the height of the crossbar of this gantry, the list not being exhaustive.
- processing module 47 determines that the system 43 is unable to manage crossing the level crossing and/or that the vehicle 4 is not authorized to cross the level crossing, it can decide for example:
- the processing module 47 is advantageously configured to assist the module(s) detection device 45 so that it(s) detect(s) structural characteristics corresponding to one or more pieces of information extracted from message(s) received, by means of the exteroceptive sensor(s) 44.
- a particular advantage of this embodiment is that the on-board system can in particular anticipate the presence of a level crossing, with an increased confidence indicator due to a large number of structural characteristics than the indications contained in the (s) message(s) will allow it to detect via its own sensors. Furthermore, even if one of the messages is of type DENM and already contains, according to the standards, direct information on the presence of a level crossing (via the specific variable named "eventType"), the on-board system 43 can combine this direct information with the structural characteristics that it has detected, further increasing the confidence indicator linked to the detection of the presence of a level crossing. The on-board system 43 is then advantageously able to better prepare for the approach phase by deciding on the best way to manage movement control.
- the processing module 47 is further configured to determine an input boundary and/or an output boundary from at least detected structural characteristics corresponding to one or more pieces of information extracted from message(s) received and relating to one or more structural components of said signaling and/or protection system.
- the on-board system 43 can itself derive an input boundary and/or an output boundary from the structural characteristics that it has detected. It is for example possible to determine a virtual entry boundary from the position of the R24 lights and/or the barriers that the on-board system 43 can detect via its own sensors 44 following the indications contained in a received message linked to the presence such lights or barriers. Furthermore, even if a message received includes direct information relating to the position of ground marking lines defining entry or exit boundaries, the on-board system 43 can nevertheless combine this direct information with the structural characteristics that it will have. detected, further increasing the confidence indicator linked to the determination of the entry border and/or the exit border.
