• the method further has the following features.
• Bi-directional communication is radio frequency. It allows two ID objects to communicate without consuming remotely.

It is presented in non-limiting examples in the form of a badge, a key, a keyfob called "keyfob" etc. It generally comprises an I HM human-machine interface with a screen and an SCR menu, and an electronic module for transmitting a wireless signal to a receiver coupled to an on-board computer of the vehicle.
• identifying objects are known to those skilled in the art and are therefore not described here.
• the method of transmitting information from an identifying object to another identifying object comprises, in particular, the following steps:
• an identification object ID is awakened.
• the first identifying object ID1 is woken first at time t1, while the second identifying object ID2 is woken up after, at time t2.
• the awakening is effected for example manually by means of an HMI man-machine interface of the identifying object ID described later in the description (for example by pressing a button), or automatically by means of waves.
• low frequencies whether contactless or contact when the identifying object ID is close to a low-frequency base said BF located in the vehicle for example. It can also be done automatically with a radio frequency signal said RF.
• a synchronization mode MOD_SYNC is activated which will make it possible to transmit information between ID identifier objects.
• the activation is done manually by means of the human-machine interface HMI of the identifying object ID described below.
• the synchronization mode MOD_SYNC is activated at time t2 for the first identifying object ID1 and at time t4 for the second identifying object ID2.
• This manual activation makes it possible to consume less energy compared to an activation which would be automatic.
• an activation of the automatic synchronization is also possible, but it requires more resources because it assumes the detection of an identifier in a zone and the implementation of an automatic two-way communication.
• an ASK SYNC synchronization is requested in the following manner.
• the synchronization request ASK_SYNC comprises an opening of a bi-directional communication session OPEN_SSRF.
• the two-way communication session is radio-frequency. This will allow the ID ID objects to communicate with each other and remotely if necessary. In the remainder of the description, this nonlimiting example of an RF radio-frequency communication session is taken.
• This OPEN_SSRF logon is done via a signal, here radio-frequency (RF) MSG_SYNC1 which is sent to the second identifier object ID2, here at time t3.
• RF radio-frequency
• this NS number is the vehicle number V to which all the identifiers have access. Indeed, such a vehicle number is stored in memory in all the identifiers objects that allow access to said vehicle V. So in the example taken, the first and second identifiers ID1 and ID2 have this number in memory.
• this number NS is a number specific to the second identifying object ID2, which will also be stored in memory in the first identifying object ID1.
• an ASK_SYNC synchronization request and therefore an opening of an OPEN_SSRF communication session is done after a control of the vehicle number.
• the first identifying object ID1 verifies that an acknowledgment ACK has been returned by the second identifying object ID2. This makes it possible to check whether the second identifier object ID2 is available (that is to say awake and in synchronization mode).
• the first identifier ID1 waits for a radio frequency communication signal for a determined period of time TIMEOUT0. In a non-limiting example, this time is set at 5 seconds. As can be seen in FIG. 2, it receives a message MSG_ASK2 from the second identifier ID2, at time t6, corresponding to an RF communication signal that requires synchronization.
• the first identifier ID1 sends an acknowledgment ACK via a message MSG_ACK1 to the second identifier I D2 to read that it is available to make a synchronizer. isation.
• the reception of acknowledgment ACK means that a two-way radio-frequency communication session is initialized for the first identifying object I D1 and the second identifying object I D2.
• the verification performed in the third substep 33 is negative, after the determined time interval TIMEOUTO, sends a message MSG_FAIL meaning that the synchronization request has failed, and we return to the state of idle standby. This message enables a user of the first identifier object ID1 to know that the second identifier ID2 is not available.
• the two-way radio-frequency communication session SSRF will then allow an exchange of information between the two identifiers objects ID1 and ID2 in the form of radio-frequency signals.
• a radio-frequency RF signal is around 433 MHz. Up to GigaHz can be used for the RF signal based on the frequency bands available for different countries (315 MHz for Asia, 868 MHz for some European countries or 915 MHz in America, etc.).
• the RF signals are greater than 1 MHz unlike low frequency signals BF.
• the two identifiers ID1 and ID2 will be able to communicate if they are several hundred meters apart, generally between 100 and 600 meters with a typical value of 200 meters for 868 MHz for example.
• the first identifying object ID1 is in the vicinity of the vehicle V and if the second identifying object ID2 is in the habitat of the user of the vehicle V, they will be able to communicate.
• the second identifier object ID2 when it receives an ASK_SYNC synchronization request from the first identifier object ID1 at time t3, nothing happens because it is not available.
• the synchronization mode has not yet been selected at home in the example taken in FIG. 2.
• the second identifier ID2 sends an ASK_SYNC synchronization request via a message MSG_ASK2 to the first identifier ID 1, this request ASK_SYNC including a bi-directional communication session opening OPEN_SSRF.
• the second identifier ID2 receives an acknowledgment ACK via a message MSG_ACK1 from the first identifier ID1 meaning that the latter is available for synchronization.
• a data frame (not shown) is therefore used for:
• this frame comprises a synchronization bit SYNC making it possible to know that a synchronization request is requested. This bit is therefore activated for a synchronization request ASK_SYNC when opening the communication session OPEN_SSRF.
• a date DT associated with PQ information included in the identifier object is sent at the opening of the communication session OPEN_SSRF. As will be seen below, this date DT corresponds to information updated after access to the vehicle V by an identifying object ID.
• a date DT1 associated with information in the first identifier object ID1 is sent to the second identifier ID2 during the synchronization request ASK_SYNC (and thus opening the session OMEN_SSRF) by the first identifying object ID1, while a date DT2 associated with information in the second identifying object ID2 is sent to the first identifying object ID1 during the synchronization request ASK_SYNC (and thus opening the session OMEN_SSRF) by the second identifier ID2.
• a fourth step 4 information is transmitted between the two identifying objects ID1 and ID2.
• the information transmitted is in a non-limiting example of the information relating to the vehicle. They concern for example:
• GPS Global Positioning System
• destination addresses Of course, other information can be transmitted related or not to the vehicle such as for example a graphical environment of an identifying object ID.
• the information described above is vehicle information that is updated after access to said vehicle V by an identifying object ID.
• the information to be transmitted will be those corresponding to the last vehicle access so that each identifying object includes the same information and the most recent.
• an update date is saved in the identifier object. This date associated with the updating of the information will make it possible to determine what is the information corresponding to the last vehicle access.
• the transmission of information will thus be based on this date and be determined in particular according to a comparison of dates respectively associated with vehicle information included in the first identifying object and vehicle information included in the second identifying object.
• a date comparison is made in a single identifier object, and the information whose date is the most recent will be transmitted to the identifying object containing the oldest information so that they are updated.
