Definitions
- the present invention relates to the detection of an identifier in an area associated with a vehicle.
- It relates more particularly to a device and a method for determining the presence of an identifier, as well as an associated computer program.
- the invention applies particularly advantageously in the case where it is possible to use a detection zone of the elliptical shape identifier.
- the respective distances between the identifier and a plurality of beacons are evaluated, for example, typically based on the respective flight times of radio waves used in wireless links established between the identifier and these beacons.
- the present invention proposes a device for determining the presence of an identifier in an area associated with a vehicle and equipped with two beacons, the determination device comprising an analysis module designed to evaluate, by means of each of the two tags, the distance separating the identifier and the tag concerned, and to conclude the presence of the identifier in said zone if the sum of the two distances evaluated is less than a (first) predetermined value.
- a (first) predetermined value we can thus conclude in a very simple and very fast manner the presence of the identifier in an ellipse (whose beacons form the foci) included in the detection zone.
- the analysis module can also be designed to conclude the presence of the identifier in said area if the distance between the identifier and one of said two tags is less than a second predetermined value.
- the detection zone also includes a circle centered on this beacon.
- the analysis module can be designed to conclude the presence of the identifier in said area if the distance between the identifier and the other of said two tags is less than a third predetermined value.
- the detection zone then includes a circle centered on the other beacon.
- the analysis module is for example made in particular by means of instructions executable by the processor and adapted to implement the functions of the analysis module when these instructions are executed by the processor .
- the invention also proposes a method for determining the presence of an identifier in an area associated with a vehicle and equipped with two beacons, comprising the following steps:
- the method may also comprise a step that concludes with the presence of the identifier in said zone if the distance separating the identifier from one of said two beacons is less than a second predetermined value, as well as possibly a step concluding with the presence of the identifier. identifier in said area if the distance separating the identifier and the other of said two beacons is less than a third predetermined value.
- the distance separating the identifier and the beacon concerned is for example evaluated as a function of the flight time (or the phase difference between signals of different frequencies) of a radio transmission between the identifier and the beacon concerned.
- This radio transmission can optionally use an ultra wideband modulation.
- the invention finally proposes a computer program comprising instructions executable by a processor and designed to implement a method as proposed above when these instructions are executed by the processor.
- FIG. 1 shows schematically a vehicle equipped with a system for determining the presence of an identifier in a passenger compartment
- FIG. 2 shows the main steps of a method for determining the presence of the identifier in the passenger compartment based on previously evaluated distances between two tags and the identifier.
- FIG. 1 schematically represents a vehicle V equipped with a system for determining the presence of an identifier I in an area associated with a passenger compartment H, according to the invention.
- This system comprises a first beacon B1 and a second beacon B2 arranged in the passenger compartment H of the vehicle V.
- the zone associated with the passenger compartment H is here the set of points situated either inside a first circle Ci (of radius n) centered on the first beacon B1, ie within a second circle C 2 (of radius r 2 ) centered on the second beacon B2, or inside an ellipse E having for homes the first beacon B1 and the second beacon B2.
- such a zone can easily cover almost the entire passenger compartment H of the vehicle V.
- each of the first and second circles Ci, C 2 and of the ellipse E are tangent to the lateral edges of the passenger compartment H.
- the first beacon B1 and the second beacon B2 are placed on a straight line XX 'median for the passenger compartment H, that is to say substantially parallel to the side edges of the passenger compartment H and equidistant from these lateral edges. . Note also the distance between the first beacon B1 and the second beacon B2.
- the line XX ' is thus the direction of the major axis of the ellipse E; the length of the minor axis of the ellipse E is furthermore here equal to the width I of the passenger compartment H (that is to say to the distance separating the lateral edges of the passenger compartment H) so that the ellipse is as already indicated tangent to the side edges of the cockpit H.
- the zone used for the detection could correspond to another zone associated with the vehicle V, for example a zone covering the entire passenger compartment H and regions outside the vehicle V but located near the vehicle. vehicle V.
- the axis of the beacons B1, B2 could not be centered on the passenger compartment H, in which case the dimensions of the circles Ci, C 2 (radii) and of the ellipse E (minor axis, major axis) would be increased so that the detection zone covers the entire passenger compartment H (leaves to overflow beyond the passenger compartment H).
- the presence determination system also comprises an electronic control unit C connected to each of the beacons B1, B2 by a wired link (or alternatively, by a wireless link).
- This electronic control unit C comprises for example a processor MP (here a microprocessor) and a memory MEM, for example a non-volatile memory (possibly rewritable).
- a processor MP here a microprocessor
- a memory MEM for example a non-volatile memory (possibly rewritable).
- the memory MEM stores in particular computer program instructions designed, when executed by the microprocessor MP, to implement all or part of the method described below with reference to FIG. 2.
- the electronic control unit C could be implemented as a specific application integrated circuit (or ASIC for "Application Specifies Integrated Circuit”).
- the memory MEM also stores data used in the implementation of the methods described below, in particular data representing dimensional characteristics of the considered environment, for example the radius n of the first circle Ci, the radius r 2 of the second circle C 2 and a predetermined value S associated with the ellipse E.
- the electronic control unit C is distinct from each of the two beacons B1, B2.
- Each beacon B1, B2 may include an antenna and an associated communication electronics; according to another possibility, at least one beacon B1, B2 could comprise only one antenna, the associated communication electronics being deported, for example at the level of the electronic control unit C.
- the electronic unit of FIG. command C could be associated (or even implement) one of the two tags B1, B2.
- the identifier I is for example a transponder designed to establish a wireless communication with each of the beacons B1, B2 and possibly exchange data (for example authentication data) via the wireless communication established with the beacon concerned B1, B2 and / or, via the concerned beacon B1, B2, with the electronic control unit C.
- the wireless communication established between each beacon B1, B2 and the identifier I is here a radio link, using for example an ultra wide band (or UWB for "Ultra Wide Band") modulation.
- the identifier I and each beacon B1, B2 can thus exchange data through this radio link and / or determine the flight time of the transmission (in particular by virtue of the short duration of the pulses used in the UWB type transmission).
- Each beacon B1, B2 is designed to evaluate, on the basis of the flight time of the transmission (here by radio waves) between the beacon concerned B1, B2 and the identifier I, the distance separating the beacon concerned B1 and the identifier I.
- the first beacon B1 can evaluate the distance b between the first beacon B1 and the identifier I;
- the second beacon B2 can evaluate the distance c separating the second beacon B2 and the identifier I.
- the evaluated distances b, c can then be transmitted to the electronic control unit C for processing as described below.
- beacon concerned B1, B2 provision could be made for the beacon concerned B1, B2 to transmit to the electronic control unit C descriptive information on the flight time between the beacon concerned B1, B2 and the identifier I, and that the electronic control unit C determines the distance b, c between the concerned beacon B1, B2 and the identifier I on the basis of the information transmitted.
- the electronic control unit C can then implement the method described below with reference to FIG. 2, in which case the processor MP forms an analysis module able to determine whether the identifier I is located in the area associated with the vehicle V (precisely here in the cabin H).
- the system for determining the presence of the identifier I in the passenger compartment H can thus be used in particular to check the presence of the identifier I before starting the vehicle engine, or alternatively to control the automatic locking of the doors of the vehicle V when the identifier I is determined to be absent in the passenger compartment, or, in the variant envisaged above, how not being at a certain proximity thereof, for example in a PEPS type system (for "Passive Entry Passive Starf ').
- Such a lock is for example controlled by the control unit
- FIG. 2 presents the main steps of a method for determining the presence of the identifier I in the detection zone described above on the basis of the distances b, c evaluated as indicated above between the beacons B1, B2 and l. identifier I.
- step E2 the electronic control unit C (here precisely the processor MP) determines whether the evaluated distance b is smaller than the value n stored in the memory MEM (which corresponds to the radius of the first circle Ci illustrated in Figure 1).
- step E4 the electronic control unit C (here precisely the processor MP) determines whether the evaluated distance c is smaller than the value r 2 stored in the memory MEM (which corresponds to the radius of the second circle C 2 ).
- the electronic control unit C (precisely the microprocessor
- step E6 determines in step E6 whether the sum of the two evaluated distances b, c is smaller than the predetermined value S stored in the memory MEM, that is to say if we have: b + c ⁇ S .
- S corresponds to the length of the major axis of the ellipse E.
- S 2 I 2 + a 2 (where a is as already indicated the distance separating the two beacons B1, B2).
- the identifier I is located inside the ellipse E when b + c ⁇ S (by geometric definition of the ellipse E with respect to to his homes).
- step E6 determines whether the identifier I is inside the zone of interest, here the passenger compartment H (step E10).
- step E6 if the result of the determination of step E6 is negative
- steps E2, E4 could be implemented after step E6, in the case where b + c> S.
- the determination of the presence or absence of the identifier I in the area of interest could be carried out solely on the basis of step E6.
- This variant is particularly suitable for cases where the area of interest can be easily approximated or modeled by an ellipse.
