- the sending module 105 can obtain the last geolocation position of the second vehicle B sent by consulting the remote server, the last location position being found by means of the geolocation position of the first vehicle A and the geolocation position of the portion P.
- the network identifier is for example the MSISDN number (acronym for "Mobile Station Integrated Digital Services Network" in English terminology.
- the identification can be provided by a security device, for example a SIM card, the second terminal 110 of the second vehicle B.
- the data relating to the second vehicle B can also be used to confirm the identity of the second vehicle B.
- the network identifiers of all the vehicles that can correspond to the geolocation position (s) are obtained in the substep S636, and the signaling message MS is then sent to all the vehicles in the substep S638.
- step S530 can be repeated one or more times for the second vehicle B and / or at least one other vehicle.
- the signaling module 119 can communicate the signaling SSC to the driver of the first vehicle A.
- the driver of the first vehicle A is informed of his arrival on a risk area and the presence of the second vehicle B, which increases the vigilance of the driver of the first vehicle A and thus improves the safety of the occupants of the first and second vehicles .
- the signaling SSC corresponds for example to the emission of an image or a signaling sound, such as a sound corresponding to the triggering of a flashing light.
- the driver of the first vehicle A may furthermore take into account the content of the SSC report.
- the SSC report may allow the driver of the first vehicle to cancel the sending of the SSC report to the second vehicle B, performed at step S530.
- the driver can provide a path of the first vehicle different from the path provided by the GPS guidance device of the first vehicle A.
- the SSC signaling then makes it possible to inform the driver that a bad suggestion is sent to the second vehicle B, and can thus cancel or modify the SC suggestion manually.
- Such a signaling change SSC is typically subject to delay and safe distance constraints, beyond which the driver of the first vehicle A can not modify the suggestion SC, the signaling system 100 possibly storing a history of the reports sent. A report of the modified suggestion is then sent to the second vehicle B.
- the method may comprise, if the first vehicle A has priority, a step S640 for receiving a notification NI for taking into account said SSC signaling by the second vehicle B.
- the reception module 106 receives a notification NI for taking into account the signaling SSC, sent by the second vehicle B.
- the notification N1 of the SSC signaling informs the first vehicle A receipt of the SSC report by the second vehicle B.
- the notification NI can be a light signal, for example emitted by at least one signaling device of the second vehicle B, such as a flashing light, and / or a sound signal.
- the NI notification can take the form of an electromagnetic signal out of the visible spectrum, typically coded.
- the NI notification may take the form of a message, sent via a telecommunication network, typically the network 130.
- the second vehicle B Before sending the message, the second vehicle B, or more precisely the second terminal 110 must thus identify the first vehicle A. This identification is for example performed in the same way as in the substep S636 identification.
- the network identifier of the first vehicle A is sent, in step S632, to the second vehicle B in the signaling message.
- the notification NI for taking account of said SSC report by the second vehicle B may include an indication concerning an action performed on the second vehicle B.
- action performed at the second vehicle B means a decision and / or an adjustment made at the second vehicle B.
- the decision may be an acceptance and adoption of the SC suggestion determined at step S520, or a refusal to follow of said SC suggestion,
- the NOR notification of taking into account the SSC signal then makes it possible to inform the first vehicle A of the reaction of the second vehicle B following the SSC signaling of the behavior suggestion SC.
- the first vehicle A can then adapt its driving according to the NI notification, which also improves the comfort and safety of the occupants of the first and second vehicles.
- step S640 can be repeated one or more times, the NOR notification being received from the second vehicle B and / or at least one other vehicle.
- no notification of taking into account said SSC report is received.
- the first vehicle A is then informed that the second vehicle B is not able to send such notifications and may not be able to process the SSC report sent.
- the first vehicle A can then adapt its driving behavior.
- step S615 is not implemented and the suggestion SC is determined (step S520) then the signaling SSC sent (step S530) even if the first vehicle A does not have priority.
- Steps S635 and S640 can therefore also be implemented even if the first vehicle A is not a priority.
- the modules 112, 113, 152 and / or 114 of the second terminal 110 can also respectively implement the steps S500, S510, S615 and / or S520 of the signaling method. a suggestion of a behavior, in the same way as the modules 102, 103, 104 of the first terminal 101 (the concepts of first vehicle A and second vehicle B however being reversed).
- the steps S500, S510, S615 and S520 of the method of signaling a suggestion of a behavior are implemented by the server 120.
- the first sending module 115 of the second terminal 110 or the server 120 can implement the step S530 by sending a signal of the suggestion of the behavior of the first vehicle A to the first vehicle A .
- the second reception module 107 of the first terminal 101 then receives the signaling in a step S650, then the second sending module 108 of the first terminal 101 can send, in a step S660, a notification of taking into account the signaling to the second vehicle B.
- the suggestion is for example a suggestion of folding the first vehicle A on the underpass of the first vehicle A and / or suggestion of increasing or decreasing the speed of the first vehicle A (thus a suggestion of braking or acceleration), typically coupled with a suggestion of intensity of increase or reduction of speed.
- the first receiving module 116 of the second terminal 110 then receives the notification of taking into account the signaling (step S640).
