- FIG. 4 is a block diagram of certain steps of a method implemented by the vehicle of FIG. 1.
- a vehicle 100 comprises a device for managing a locking element of at least one opening of the vehicle 101.
- this device 101 controls the operation of the locking elements of the opening of the vehicle, in particular that of at least one lock, of at least one locking element relating to a movable window of an opening and / or at least one retractable handle.
- the management device 101 is particularly adapted to control the deployment of retractable handles and / or locking / unlocking locks.
- the management device 101 comprises a processing unit 102, comprising at least one processor and at least one data storage medium (RAM, ROM, SSD ), and a communication module 103, comprising at least one antenna for transmitting and receiving radio frequency signals.
- the communication module periodically transmits radio frequency signals, preferably at a frequency of 125 kHz, and continuously listens for radio frequency signals transmitted by other transmitters, preferably on a frequency of 433 kHz. MHz.
- the management device 101 interacts via the communication module 103 with a mobile identification device 104 suitable, between other, to transmit and receive radiofrequency signals.
- the mobile communication device 104 is also able to perform power measurements relative to the radio frequency signals it receives and to include the results of these measurements within radio frequency signals that it transmits.
- FIG. 2 The method of managing a locking element of an opening of a vehicle according to the invention is illustrated in FIG. 2.
- the management device 101 operates the communication module 103 according to a first operating mode in which the module 103 periodically transmits radio frequency signals in a first period pi through one or more antennas.
- These radiofrequency signals are intended to interrogate a mobile identification device possibly present in the vicinity.
- the value of pl is 1200 ms, this value making it possible to save the electrical consumption drawn from the vehicle battery.
- the emission of a signal involves the activation of at least one antenna, usually several, which can not be without power consumption.
- the communication module 103 thus transmits a radio frequency interrogation signal every 1200ms.
- the value of the period p1 is between 1200 ms and 1400 ms.
- the communication module 103 listens to radiofrequency signals that are transmitted on one or more frequencies, in particular on a frequency of 125 KHz.
- a step 202 when the communication module 103 receives a radio frequency signal, it is transmitted to the processing unit 102, in a raw form or previously processed within the communication module 103.
- the processing unit 102 extracting from the transmitted signal a piece of data relating to a received signal power.
- the mobile identification device 104 when it receives an interrogation radiofrequency signal transmitted by the communication module 103, invariably acts by measuring the power of the received signal (in English "RSSI" for Received Signal Strength Indication) and returning back to the communication module 103 a radio frequency signal containing the result of this measurement.
- the processing unit 102 therefore uses the power measurement communicated by the mobile identification device 104 to determine at least one value of a location parameter of the mobile identification device.
- the processing unit 102 is configured to, on the basis of the measurement of power, be able to determine how far away from the vehicle is the mobile identification device 104.
- the management device 101 operates the communication module 103 according to the first operating mode.
- the management device 101 operates the communication module 103 according to a second operating mode in which it periodically transmits radio frequency signals in a first period p2, with p1> p2, through one or more antennas. These radio frequency signals are intended to interrogate a mobile identification device in order to locate it more precisely.
- the value of p2 is 300ms, this value allowing a better location capacity of the mobile identification device 104.
- the value of the period p2 is between 300 ms and 500 ms.
- step 202 when the processing unit 102 determines that the mobile identification device 104 is at a distance between 1.2m and 1.7m from the vehicle, the device management 101 controls the unlocking of the locking elements so that the locks are open and the retractable handles deployed.
- the processing unit 102 determines, while the locking elements are unlocked, that the mobile identification device 104 is at a distance between 1.7m and 2m from the vehicle, the management device 101 commands locking the locking elements so that the locks are closed and the retractable handles find their retracted positions.
- the method according to the invention therefore establishes a plurality of areas around the vehicle, as illustrated in Figure 3, which are separated at defined boundaries, for example, by the presented numerical values to which other neighboring numerical values can substitute.
- a first "Wel" zone, located between 3 and 5 m, furthest from the vehicle, allows:
- the second zone called “UIR” zone, the closest to the vehicle, between 1.2 and 1.7m, allows:
- the third zone (WAL) zone, between 1.7 and 2m, allows:
- the mobile authentication device to accurately detect the distance of the user, i.e. the mobile authentication device
- the processing unit observes the time spent by the mobile identification device 104 in the "Wal" zone.
- This observation of the temporal evolution of the location of the mobile identification device 104 is performed using the power information that is sent by the mobile identification device 104. Consequently, when the processing unit 102 determines that the mobile identification device has been in the "Wal" zone for more than a certain time (greater than a first threshold), for example by determining the value of a parameter With a delay time greater than 30s, the management device 101 then operates the communication module 103 according to a third operating mode in which the communication module 103 periodically transmits radio frequency signals according to a third period p3, with p2 ⁇ p3 ⁇ p1.
- the value of p3 is 550ms, this value making it possible to reduce the number of interrogations to be processed by the mobile identification device 104, and thus to minimize its electrical consumption.
- the device management 101 when the processing unit 102 determines that the mobile identification device 104 stays for a period of time which is greater than a second threshold (, for example by determining a timeout value greater than 60s), the device management 101 then operates the communication module 102 according to a fourth operating mode in which the communication module 103 periodically transmits radio frequency signals according to a fourth period p4, with p3 ⁇ p4 ⁇ p1.
- the value of p4 is 1050 ms, this value making it possible to further reduce the number of interrogations to be processed by the mobile identification device 104, and thus to further minimize its electrical consumption.
- the processing unit 102 determines that the mobile identification device 104 stays for a period of time that is greater than a third threshold, for example by determining a timeout value greater than 180s
- the management device 101 operates then the communication module 102 according to a fifth operating mode in which the communication module 103 periodically transmits radio frequency signals according to a fifth period p5, with p1 ⁇ p5.
- the value of p5 is 1550 ms, this value making it possible to further reduce the number of interrogations to be processed by the mobile identification device 104, and thus to further minimize its electrical consumption.
