Definitions

  • the present invention relates to a locking assembly for a door motor vehicle and a method for testing the proper functioning of a module lock of this set.
  • an assembly for locking a door of a motor vehicle intended to be mounted in this door, of the type comprising an electric lock module carrying, on the one hand, an electronic card forming an interface intended to connect this module lock to main means of electrical supply and to means of control of the lock module, and on the other hand, of the emergency supply means the lock module in the event of a malfunction of the main means.
  • the backup means are constituted by a battery, such as a battery, carried by the electric lock module.
  • This battery separate from the electronic card, is arranged for example in a housing of the module lock.
  • the battery is connected to the electronic card by connecting means electric generally comprising tracks or conductive wires.
  • Document FR 2 759 108 discloses a door locking assembly vehicle comprising a lock supply motor connected by connections electric to a vehicle battery and a backup power supply. This way backup consists of a battery, a capacitor and an electrical circuit allowing limit the voltage supplied to the motor.
  • the electrical connections between the supply motor and the battery or emergency means are also subject to risks of disconnection, oxidation, etc.
  • the electrical current supplied by the batteries normally used to train the backup batteries is not sufficient for certain applications requiring an intensity which can reach or even exceed 3 A.
  • the document EP 0 533 037 describes an electrical device advantageously using a supercapacitor so as to allow its activation with high electrical power over a short instant.
  • the invention aims to increase the reliability of the means emergency power supply carried by the electric lock module, while allowing these emergency means to deliver a relatively high intensity.
  • the invention relates to a door locking assembly motor vehicle according to claim 1.
  • the invention also relates to a method for testing the good operation of the lock module of an assembly as defined above, characterized in that this test is carried out before the electrical connection of the lock module to main means of electrical power and after electrical charging of the electronic energy storage component, using software programmed in storage means electrically powered by the electronic component energy storage.
  • FIG. 1 shows an electrical installation of a vehicle automobile, intended for locking a door of this vehicle, designated by the general reference 10.
  • This installation 10 includes a set 12 for locking the door intended to be mounted in this door.
  • the assembly 12 includes a conventional electric lock module 14 carrying an electronic card 16 forming an interface intended to connect this module of lock 14 to main means of electrical supply and to means of control of the lock module.
  • the main means of electrical supply include a housing classic centralized electric 18 electrically connected to a main battery 20 of the vehicle. If necessary, this main battery 20 can be doubled by a battery secondary backup (not shown) taking over from the main battery if the latter malfunctions.
  • the control means of the lock module include a handle outer door 22, an inner door handle 24 and, in the case for example of a front door, an electronic barrel 26.
  • These members 22, 24, 26 include conventional electrical switches including opening and / or locking states and lock unlocking are transmitted to the centralized box 18 and to the card electronics 16.
  • the assembly 12 also includes emergency means 28 for the power supply to the lock module 14 in the event of a malfunction of the main supply means 18, 20.
  • These backup means 28 comprise at less an electronic energy storage component, carried by the card electronics 16, consisting of a supercapacitor 30.
  • the supercapacitor 30 has an energy density mass between 0.4 and 10 Wh / kg and a maximum charge intensity or discharge between 1 and 10 A for a voltage between 0.8 and 14V.
  • the capacity of the supercapacitor 30 can reach 4 to 8 F or even exceed these values.
  • the supercapacitor 30 constitutes a source of energy rechargeable and compact.
  • the emergency means 28 preferably comprise several supercapacitors 30 mounted in series or in parallel.
  • the emergency power supply means 28 include at least two supercapacitors 30, namely six supercapacitors 30 in the illustrated case, mounted serial.
  • the emergency supply means 28 according to the two other modes of implementation are aimed at increasing the reliability of these emergency means.
  • the emergency supply means 28 comprise at least two groups of supercapacitors 30.
  • Each group in this example includes six supercapacitors 30.
  • the supercapacitors 30 of the same group are mounted in series.
  • the two groups are mounted in parallel. So the failure of the operation of a supercapacitor 30 in a first group does not prevent the operation of the second group of supercapacitors 30.
  • the emergency supply means 28 according to the third mode of embodiment illustrated in FIG. 4 comprise at least one pair of supercapacitors 30 mounted in parallel, namely, in the example illustrated, six pairs supercapacitors 30. Preferably, these pairs are connected in series. So the failure of one of the supercapacitors 30 does not prevent the operation of other supercapacitors 30.
  • a diode 32 or any other similar device prohibits the discharge of supercapacitors 30 in the main supply means 18,20.
  • the supercapacitors 30 are mounted directly on the card electronics 16, for example by usual welding techniques applicable to conventional through-type components (component connection pins crossing the card) or CMS (component for surface mounting). This avoids various risks linked to the use of connection means between the electronic card and the backup battery according to the state of the art described in EP-A-0 694 664 (short circuit, disconnection, oxidation, resistance variation, etc.)
  • the power supply means emergency 28 are not used as long as the main supply means 18,20 operate normally. These maintain the supercapacitors 30 in permanently in charge.
  • duration to charge a supercapacitor 30 is relatively short namely a few tenths of a second to a few tens of seconds.
  • the electronic card 16 can warn the user of this changeover by controlling an alarm light placed on the door or on the dashboard of the vehicle or sending an alarm message on an on-board computer screen of the vehicle.
  • the emergency power supply means 28 with supercapacitors can allow the operation of the lock module 14 for several cycles opening or closing for example, in some cases, ten cycles.
  • the electronic card 16 comprises means for storage 34, capable of being supplied electrically by the means emergency power supply 28, in which a software for testing the good is programmed operation of the lock module 14.
  • Such storage means may include a memory classic programmable type EEPROM (Electrically Erasable and Programmable Read Only Memory).
  • EEPROM Electrically Erasable and Programmable Read Only Memory
  • test is performed automatically using the software programmed in the EEPROM memory electrically powered by supercapacitors.
