Definitions

  • the present invention relates to a system for safety, especially for motor vehicles.
  • a system comprising a fixed terminal and an object portable capable of delivering an unlock signal at the fixed terminal.
  • the fixed terminal consists of the central central locking / unlocking of the vehicle
  • the portable case is constituted by a case of remote control for closing and opening at distance from vehicle doors.
  • the portable object is intended to be carried by a authorized user, including the owner of the vehicle. Its function is to deliver, under certain conditions, a signal from locking / unlocking at the fixed terminal. This signal is generally emitted by carrier wave (wave electromagnetic or infrared wave).
  • carrier wave wave electromagnetic or infrared wave
  • the locking / unlocking signal delivered the portable unit usually has a fixed code or scalable (i.e. whose value is a based on the number of programs previously which must be recognized as valid by the terminal fixed to cause locking or unlocking the vehicle doors.
  • the object of the invention is to overcome this disadvantage of art security systems prior.
  • the idea on which the invention is based consists in associate the security system with his (or her) authorized user (s), so that only this (s) (or these) can (s) cause the unlocking of vehicle doors.
  • the invention proposes to use means for measuring a user's biometric signature (or authorized users).
  • a signature biometric is for example defined by a fingerprint digital, the iris of the eye, or an audiometric spectrum the voice of the authorized user.
  • such a system can present a risk accidental unlocking of the vehicle doors, for example if the authorized user pronounces by inadvertently a word or a sequence of words suitable for unlock the doors while it is is near the vehicle. If he doesn't go not count, he can get away from his vehicle and leave unattended while the doors are unlocked.
  • Another object of the present invention is to suggest ways to prevent any untimely unlocking of the vehicle.
  • the housing function remote control associated with the portable object is preserved, so that the current habits of users are not deeply changed.
  • FIG 1 there is shown schematically a functional unit constituted in the example of realization of the invention by a motor vehicle 101.
  • This one is equipped with a fixed on-board terminal such as a central locking / unlocking centralized 102.
  • the system also includes a portable object 103 such as a remote control unit associated with a key of the vehicle.
  • a portable object 103 such as a remote control unit associated with a key of the vehicle.
  • the housing portable is confused with the remote control box or the vehicle key, and these three expressions are indistinctly used, unless it is otherwise arranged.
  • This portable case is intended for be worn by an authorized user 104 such as the vehicle owner. Other users authorized users may also be required to use the portable box 103 or another similar box which is more personally attributed to them.
  • the portable box 103 is intended to deliver, under certain conditions, a signal of locking / unlocking SD at the fixed terminal 102.
  • This unlock signal can be transmitted by wave carrier such as an electromagnetic wave or a infrared wave. In the first case, it can be of a radio frequency signal modulated in amplitude or in phase.
  • the key 103 conventionally comprises a part metallic 12 forming a key insert, as well as a plastic housing 11 forming head or part of gripping the key.
  • the housing 11 performs a function remote control and for this purpose contains a circuit electronic signal transmission unlocking SD above.
  • the housing of remote control includes means for detecting a active user intervention.
  • These means can for example include one or more keys a keyboard. More simply, these means include a SW switch, for example of the type push button, placed under a first region 13 of the remote control unit 11. This is made of plastic material. Due to the reduced thickness or of adjacent ribs, part 13 of the housing can be bend under the pressure exerted by the thumb 15 of the user in order to activate the switch SW contained in the housing 11 (and which, for this reason, is shown in broken lines in Figure 2).
  • the remote control unit 11 further includes means for measuring a signature biometric of an authorized user of the vehicle.
  • a such means may include a microphone and a voice recognition device to identify the voice of the user.
  • this medium includes a CED fingerprint sensor arranged inside the housing 11 (and which for this reason, is also shown in broken lines in Figure 2) whose active surface is flush with the surface of the housing 11 of the key head.
  • Such sensors are now available in the form of monolithic integrated circuits at a price compatible with the nature of the market for security systems for motor vehicles and which are sufficiently precise and reliable and compact for this type of application.
  • the active surface of this sensor is less than 2 cm 2 .
  • This active surface includes nearly one hundred thousand detection points arranged in a matrix.
  • the sensor delivers digital data in series corresponding to a scan of its active surface. The entire active surface is scanned eight times per second.
  • the fingerprint sensor is arranged in a region 14 of the housing 11 which is opposite to the region 13 above so that the user's index 16 is in contact with part 14 while his thumb 15 is in contact with part 13, when the housing 11 is pinched between these two fingers.
  • the senor can also be disposed on the surface of the housing 11 at the level of the part 13 above, so that the 15 inch of the user is applied against the active surface of the sensor and also exerts through it a pressure to activate the push button SW of the remote control.
  • FIG 3 there is shown a diagram of the portable object according to the invention. More specifically this is a block diagram of means of the invention included in the portable object.
  • the portable object comprises means of detecting an active intervention of a user. These means produce a signal SA1 activation.
  • these means include the SW switch one terminal of which is connected to the positive terminal of a voltage source positive ST1 with negative supply terminal connected to ground.
  • the activation signal SA1 is then delivered by the other terminal of the switch SW. In this way, the signal SA1 is active in the state logic 1 when the SW switch is closed.
  • these means include the switch SW and, in particular when the SW switch is stealthy like a button pusher, they further include a means of time delay MS1.
  • the first terminal of the switch SW is connected as stated above, and its other terminal is connected to the input of the means of MS1 timer, the output of which outputs the signal SA1 activation.
  • This means of delay is by example a monostable time constant circuit T. It has the effect of maintaining the activation signal SA1 in the active state during a time window determined (corresponding to its time constant T), after closing the SW switch. So even if the pressure exerted by the user's thumb 15 on the SW switch is stealthy, the signal activation SA1 is kept active for said time window.
  • the portable case also includes a means of measurement of a biometric signature of the user which, as said before, is preferably a CED fingerprint sensor. This sensor delivers a measurement signal SM2.
  • the portable housing further includes means for generation of the SD unlock signal, including function is to produce the unlock signal when the activation signal SA1 and the signal SM2 measurement are produced in the time window determined T on the one hand, and when the signature measured corresponds to that of an authorized user on the other hand.
  • the management circuit 20 includes furthermore a microcontroller M1 comprising a memory DB2 in which the biometric signatures of one or of several authorized users are memorized (i.e. here the fingerprint of the thumb or index finger as appropriate, or any other finger). These signatures can be stored in the form of a binary data matrix.
  • the signatures biometric of each authorized user are stored in separate areas of DB2 memory referenced by a user number. For example we can provide five separate areas for storing biometric signatures of five authorized users different corresponding to the members of the same family, each of which is fictitiously associated a user number 1, 2, 3, 4 or 5 respectively.
  • the signal SM2 delivered by the sensor Fingerprint CED is a digital signal.
  • the data provided on the second input E2 of the unit 20, are therefore directly exploitable by the microcontroller M1. Otherwise, you must provide an analog / digital converter.
  • the microcontroller M1 is controlled by a program Management.
  • the data contained in the measurement signal SM2 correspond to the data stored in one of the five memory areas of the DB2 memory of the M1 microcontroller, this delivers on an OUT output a signal transmitted to a circuit ER2 emission to cause the emission of the signal of SD unlocking via, for example, an antenna or a infrared diode.
  • the signals SA1 and SM2 can be transmitted on two separate entries of the microcontroller M1 to be treated in a AND type logical operation.
  • the window time T during which the signal SA1 is maintained in the active state, must at least be equal to the duration of data transmission corresponding to a user's fingerprint by the signal of SM2 measurement. A 500 millisecond time window is sufficient.
  • the portable object further comprises at minus another means of measuring biometric data of the user producing another measurement signal.
  • the means for generating the unlocking signal SD then produce the SD signal when the signal activation SA1 and all measurement signals are products in the aforementioned time window T, and when the signature measured corresponds to that of a authorized user and in particular of his fingerprint digital.
  • Such other biometric user data can consist of measured blood pressure at his finger.
  • the means of measuring this biometric data then includes a CPR pressure.
  • biometric datum of the user can still be incorporated by the temperature of his finger.
  • the means of measuring this biometric data then includes a PTC temperature.
  • FIG 3 there is schematically shown a second logic gate PL3 of type ET which receives the SM3 measurement signal from the pressure sensor CPR on a first input, and the activation signal SA1 on a second input.
  • the exit from gate PL3 is transmitted on a second input I2 of the microcontroller M1.
  • a third logic gate PL4 of type ET which receives the measurement signal SM4 generated by the PTC temperature sensor on a first input, and the activation signal SA1 on a second input.
  • the output of gate PL4 is connected to a third input I3 of the microcontroller M1.
  • the unlocking signal SD comprises a impersonal code identifying that of users authorized whose biometric signature has been recognized valid.
  • This impersonal code can simply be consisting of user number 1, 2, 3, 4 or 5 cited above. This allows the activation of comfort in the vehicle upon reception of the SD signal. Of such functions consist for example in the adjustment of seat height, position of rear view mirrors, a set temperature for a on-board air conditioning system, station radio, etc ..., to predefined values corresponding to the usual choices of the user concerned.
  • the unlocking signal SD also includes a vehicle identification code with which the portable object is associated allowing to associate a specific portable object with a unique vehicle.
  • the structure of the fixed terminal for example made up by the central locking / unlocking vehicle doors is not specific to the invention and can therefore conform to those of art systems prior. At the very least, it is within reach of skilled in the art, and for this reason is not described in detail in this discussion.
  • the signal locking / unlocking can also include a scalable code, i.e. a code whose value changes with each transmission.
  • a code whose value changes with each transmission.
  • fraud attempts consisting in capture and record (with electronic means adapted) the lock / unlock signal when issued normally by the user authorized, in order to reproduce it later fraudulently.
