Definitions

  • the invention relates to a security system for a door leaf of a motor vehicle.
  • the invention relates more particularly to a security system for a motor vehicle opening, of the type in which the opening is held in the closed position by a lock which is controlled by means of a handle, and of the type in which the security system includes means for detecting the presence of a hand of a user near the handle.
  • Such a system is for example described in the document FR-A-2,733,783.
  • the system described in this document proposes to use as a means of detecting the presence of the hand an infrared radiation sensor.
  • This sensor "observes" an area of space around the detection lever so that, when a user approaches his hand to the handle, the infrared radiation emitted by the hand is collected and analyzed by the sensor which is then susceptible to transmit control information to an electronic module of the security system.
  • infrared radiation sensor is however unsatisfactory. Indeed, the infrared radiation emitted by the hand of the user can vary very significantly depending on many parameters. In particular, when the user is wearing gloves, the infrared emission from the hand may be considerably reduced to the point of becoming undetectable.
  • the security system equipped with such a sensor does not have enough guarantee of reliability in the detection of the hand to ensure this function in all possible situations of current use of a vehicle.
  • the principle of this device is therefore to detect a variation in the capacitance of the capacitor, which is generally carried out by integrating this capacitor in an oscillating electronic circuit whose oscillation frequency is checked.
  • the variation in capacitance of the capacitor, and therefore the presence of the hand, is detected by a variation in the oscillation frequency of the circuit.
  • the object of the invention is to propose a new design of the means for detecting the presence of the hand near the handle which are both inexpensive to implement and which allow particularly effective detection on the one hand in terms of sensitivity and, secondly, in terms of resistance to parasitic external influences.
  • FIG. 1 There is illustrated in Figures 1 and 2 a handle 10 of a motor vehicle, for example intended to be mounted on a vehicle door to allow the opening.
  • the handle 10 is a handle of the "refrigerator" type intended to be mounted in relief with respect to an external sheet metal panel (not shown) of the opening of the vehicle.
  • the handle 10 thus comprises, at outside the opening, a gripping lever 12 which is movable between a rest position illustrated in FIGS. 1 and 2 and an open position (not shown) in which the lever 12 is spread outwards by relative to the sheet metal panel by the hand of the user, and in which the lever 12 actuates a lock mechanism (not shown), possibly by means of a transmission linkage (not shown).
  • the user engages his hand between the lever 12 and the sheet metal panel, thereby acting on a rear surface 14 of the lever 12.
  • the handle 10 also includes a lock cover 16 which is arranged outside the sheet metal panel, which is fixed and which has a bore 18 intended to receive, for example, a rotary lock intended to prevent actuation of the lock.
  • the handle 10 also comprises internal parts 20, 22, which are arranged on the internal side with respect to the external sheet panel, which allow in particular the fixing of the handle to the opening as well as the connection of the handle 10, and more particularly of its lever 12, with the lock mechanism that the handle is intended to control.
  • the security system includes means which make it possible to detect the presence of the hand of a user when this arrives near the handle, but before there is actually contact between the hand and the handle.
  • the security system according to the invention will advantageously be implemented in the context of a security system comprising means of remote identification of the user.
  • the user carries an identifier, for example a transponder which, in response to a interrogation signal emitted by the security system, returns an identification code specific to this transponder. If the identification code re-issued by the transponder corresponds to the code expected by the security system, the latter will unlock the doors of the vehicle. The user can then open the opening simply by acting on the handle 10, without first having to engage a key in the lock and without having to operate a remote control.
  • the exchange of information between the security system and the transponder carried by the user generally uses high frequency electromagnetic links which consume a significant amount of energy and which constitute a source of electromagnetic "pollution". It is therefore desirable that the identification process is not carried out continuously when the vehicle is locked.
  • the identification and unlocking processes require a significant amount of time which, if they are triggered only when the user already has their hand on the handle, generates a latency time during which the user can handle the handle. without causing the opening of the opening. This latency is generally perceived as unpleasant.
  • the means for detecting the presence of the hand essentially comprise a transmit antenna 24 and a receive antenna 26 which, in the two embodiments of the invention illustrated in FIGS. 1 and 2, are integrated to the handle 10.
  • the transmitting antenna 24 and the receiving antenna 26 are both produced in the form of a metallic conducting wire; and they are arranged longitudinally, parallel to one another, in the lever 12 of the handle 10.
  • the transmitting antenna 24 is produced by using a fixed metal part, which can for example consist of a tubular jacket in which the lock is intended to be received.
  • the reception antenna 26 is constituted by the transmitter and / or the receiver of a recognition circuit by which the security system performs the recognition and identification of the transponder carried by the user.
  • the transmitter or the receiver of the recognition circuit which is produced in the form of a coil integrated into the lever 12 and which is therefore also used to ensure the detection of the approach from the hand.
  • the transmit 24 and receive 26 antennas are connected to a detection circuit 28, more particularly visible in Figure 3, which has two separate parts.
  • the detection circuit 28 includes a generator 30 which applies to the transmitting antenna 24, optionally by an amplification circuit 32, a periodic potential.
  • the reception antenna 26 is connected, possibly by a second amplification circuit 34, to means 36 for measuring and comparing the signal received by the antenna 26.
  • a voltage will be used whose frequency is substantially within a range varying from 1KHz to 1MHz.
  • the level of the signal received by the reception antenna 26 is lower than that transmitted by the transmission antenna 24.
  • the means 36 for measuring and comparing the detection circuit 28 are capable of measuring the amplitude A of the variation in the potential difference between the reception antenna 26 and an electrical reference, for example the ground vehicle.
  • the measurement and comparison means 36 to compare the amplitude A of the potential difference received at the reception antenna 26 with a reference amplitude A ref to deduce therefrom the presence or not of the hand and to optionally transmit hand detection information.
  • the invention can be implemented using either a fixed reference amplitude A ref , or a variable reference amplitude A ref .
  • the operation of the detection circuit 28 has been illustrated in the case where the reference amplitude A ref is fixed.
  • the detection circuit 28 transmits hand detection information when the measurement and comparison means 36 measure an amplitude level A of the signal received by the reception antenna 26 which becomes less than the amplitude reference A ref .
  • variable reference amplitude A ref this in particular in order to take account of a gradual variation in the coupling characteristics between the transmitting antenna 24 and the receiving antenna 26, a variation which may for example be due to a change in atmospheric conditions.
  • reference amplitude A ref a filtered value of the amplitude A of the signal received by the receiving antenna 26.
  • a filter having a relatively long delay time will be used , for example of the order of a few seconds.
  • the detection circuit 28 does not generate detection information of the hand and it therefore interprets this change in the amplitude level A as resulting from a slow change in the environment of the handle 12, independent of the presence of a user.
  • the instantaneous level A of amplitude of variation of the potential difference at the level of the receiving antenna 26 drops rapidly as is illustrated in FIG. 6.
  • the reference amplitude A ref being obtained by filtering the instantaneous amplitude level through a filter with a high delay time, a significant difference is created between the instantaneous amplitude level A and the reference amplitude A ref , the detection circuit 28 then being able to interpret this large difference as being the result of the approach of the hand of a user.
  • the detection circuit 28 When this difference exceeds a predetermined threshold, the detection circuit 28 generates information for detecting the presence of the hand which is transmitted to the security system, which can then trigger the process of recognizing the identifier carried by the user and , if necessary, trigger the unlocking process of the door.
  • one of the transmitting or receiving antennas 24 or 26 is constituted by a transmitter / receiver element for the recognition circuit
  • the two circuits do not have to be used at the same time because the recognition process is only implemented when a user has been previously detected by the detection means .
  • the antennas 24, 26 are carried by the handle 10, which is particularly advantageous in terms of time for mounting the system on the vehicle.
  • the invention may also be implemented in a security system in which the antennas are carried for example by the opening of the vehicle.
  • the detection circuit 28 may or may not be arranged on the handle.
