Definitions

  • This invention relates to vehicle security systems, and is particularly concerned with such systems as used to protect motor vehicles against improper use and which are able to be controlled from a remote location.
  • Security systems of the kind to which the invention relates generally include an alarm mounted in the vehicle and which, when armed, will emit a signal if the associated vehicle is tampered with.
  • the alarm can be armed and disarmed from a remote location by means of a transmitter which is operable to emit a coded radio frequency (RF) signal.
  • RF radio frequency
  • the security system in the vehicle responds to that (RF) signal by arming or disarming, as appropriate, the alarm.
  • Some security systems also control the effective operation of the vehicle engine start system.
  • the relevant control means is generally switchable between two conditions in which operation of the start system is enabled and disabled respectively. Any suitable means may be utilised to effect switching between those conditions, including receipt of a signal from the aforementioned transmitter.
  • the transmitter usually forms part of a portable (RF) signal generating device and is contained within a housing of that device which also contains a small battery arranged to provide the transmitter power source.
  • a press button switch is selectively operable to connect the battery and transmitter so as to cause generation of the coded signal.
  • Effective operation of the signal generating device may be hinderded or prevented in a variety of ways.
  • the battery may have lost its charge, or may have insufficient charge to effectively operate the transmitter.
  • Location of the transmitter in close proximity to radio towers or the like can also render the signal generating device ineffective. The consequence of such a malfunction can be quite dramatic.
  • the alarm may continue to operate and/or it will not be possible to start the vehicle engine.
  • One proposal for meeting the foregoing problem is to provide a special by-pass key which is usable to disarm the security system, but that has the disadvantage of diminishing the overall level of security of the system. It is an object of the present invention to provide a relatively simple and effective solution to the aforementioned problem.
  • a vehicle security system including, detection means operable to adopt either an armed condition or a disarmed condition in which it indicates proper and improper use respectively of the vehicle with which the system is associated, a portable signal generating device having a transmitter, a battery and switch means which is selectively operable to connect said transmitter and battery, said transmitter being responsive to connection with a power source to transmit a coded signal and said battery forming a said power source, said detection means being responsive to receipt of a said signal to adopt either one of said conditions thereof, and an auxiliary power source separate from said device and being operable to enable operation of said transmitter independent of or through said battery.
  • the detection means may take any of a variety of forms. In many cases it will include or comprise an alarm which is operative to produce an audible signal, which if sounded will be an indication of (attempted) improper use of the associated vehicle. Absence of the alarm signal is by corollary an indication of proper use.
  • the detection means may also include or comprise means which controls the vehicle engine start system, in which event disabling of that system is an indication of improper use and enabling of the system is an indication of proper use. It will be appreciated from the foregoing that an "indication" as referred to in the preceding paragraph of the specification need not be a visible or audible indication, but could be a result or absence of a result of performance of a certain activity such as use of a vehicle ignition key.
  • the auxiliary power source will be the battery of the associated vehicle, and connection of that battery to the signal generating device can have a number of consequences. If the battery of the device is rechargeable, such connection may result in that battery being charged. Alternatively or additionally such connection may activate the transmitter so that a signal is generated.
  • the signal generating device may be of the conventional kind which is a stand-alone unit adapted to be carried to and from the vehicle. Quite often such devices are connected to the key ring to which the vehicle ignition key is connected. In a preferred embodiment of the invention, the signal generating device forms part of the head of the vehicle ignition key.
  • a portable signal generating device having a transmitter, a battery and switch means which is selectively operable to connect and disconnect respectively the transmitter and battery, said transmitter being responsive to connection with a power source to transmit a coded signal and said battery providing a said power source, and contact means connected to said transmitter or said battery and being connectable to a power source separate from said device.
  • the signal generating device is built into the head of a vehicle ignition key.
  • Figure 1 is a block diagram showing one embodiment of the invention.
  • a security system is characterized in that it includes back-up means which -4- enables transmission of the required coded signal in circumstances where the signal generating device is ineffective for any reason such as the transmitter battery having inadequate charge or being inoperable.
  • the back-up means can operate in any one of a variety of ways. It may for example operate to charge the transmitter battery, or it may operate to provide an independent or auxiliary power source for the transmitter. It will be convenient to hereinafter particularly describe an embodiment of the invention in which the back-up means provides an auxiliary power source for the transmitter.
  • the signal generating device or actuator is usually a relatively small device which is often either built into the ignition key head or is attached to the key ring which carries the ignition key for the relevant vehicle.
  • the actuator will therefore be located adjacent the ignition switch of the vehicle when the vehicle is in use, and the present invention makes use of that relationship.
  • the actuator 1 forms part of an ignition key 2.
  • the actuator 1 is conveniently provided in the head 3 of the key 2, and is of conventional form in that it includes a transmitter 4,
  • a switch 7 is selectively operable to connect the transmitter 4 and battery 6 and thereby result in generation of a coded signal.
  • the signal generated in the illustrated example is a radio frequency (RF) signal.
  • RF radio frequency
  • a vehicle which is represented by the block 8, will have a receiver 9 which receives the RF signal and transmits that signal to a decoder 10 which forms part of the vehicle security system 11.
  • That security system 11 may be alarm base or it may be based on some other function such as control of the vehicle start system.
  • a combination arrangement which is both alarm based and vehicle operation based may be employed, and such an arrangement will be hereinafter described.
  • the alarm 11 includes an alarm 12 and a control unit 13 for the vehicle engine start system.
  • the consequent signal operates in a known manner to disarm, or arm, the alarm 12, and to enable or disable the vehicle start system through the unit 13.
  • the operator presses the switch 7 to connect the battery 6 and transmitter 5.
  • a coded signal is then generated which is sent by the transmitter 4 along a path 14 to the receiver 9 of the vehicle 8.
  • the received signal then conditions the security system 11 as required in a known manner. Assuming the actuator 1 is operated from a remote location to disarm the alarm 12 and enable the engine start system through the unit 13, it is preferred that the enabling function is limited to a period of time - for example, 30 seconds. If the correct ignition key is not inserted into the ignition keyway of the vehicle within that time, the security system preferably operates to automatically disable the engine start system.
  • the by-pass facility hereinafter described operates to sense whether or not a correct key has been inserted into the ignition keyway.
  • the arrangement shown in the drawings has a by-pass facility which comes into operation in the event of malfunction of the actuator 1.
  • That facility includes a contact 15 provided on the key head 3, or at any other suitable location, so as to be engageable with a cooperable contact 16 located within the vehicle 8.
  • the contact 16 is in the form of an annulus, or part thereof, which is disposed around the vehicle ignition keyway 17. The arrangement is such that the two contacts 15 and 16 engage when the key blade 18 is fully inserted into the keyway 17 and the key 2 is turned towards the vehicle start position.
  • the key 2 causes operation of a switch 19 which connects the vehicle battery 20 to the decoder 10 and to the contact 16. Second, because of engagement between the contacts 15 and 16 and the connection of the latter contact to the vehicle battery
  • the battery 20 is connected to the transmitter 4 and provides a power source for that transmitter.
  • the second consequence results in the generation of a coded signal by the actuator 1, and that signal is transmitted to the decoder 10 along the path 21.
  • the received signal then functions in the same manner as it would if received through the receiver 9.
  • the alarm 12 is disarmed, and the unit 13 operates to enable the engine start system.
  • a timer 22, or other suitable means, may operate to cease transmission of a signal along the path 21 after the intended purpose of that signal has been accomplished.
  • the actuator 1 When the ignition system of the vehicle is de-energised by the reverse rotation of the key 2 and subsequent withdrawal of the key 2 from the keyway 17, the actuator 1 may be operated to return the security system to a secure condition. It is preferred however, that means is provided to prevent such rearming for a predetermined period of time - e.g., to allow the vehicle occupant to leave the vehicle. Any suitable electronic circuitry may be employed for that purpose, and the block 23 is representative of that circuitry. Preferably, the relevant circuitry 23 forms part of the decoder logic.
  • actuator battery 6 is of the rechargeable kind, engagement between the contacts 15 and 16 may cause that battery to be recharged through the resulting connection with the vehicle battery 20.
  • the arrangement preferably provides for the decoder 10 to change its mode of operation.
  • the system may sense movement of the key 2 towards the vehicle start position, an if data is not received along the path 21 -7- after a predetermined period of time (say two seconds), the system may respond by causing the decoder 10 to switch to monitor incoming data received through the receiver 9. Any suitable means may be adopted for that purpose.
  • the actuator 1 could be formed separate from the key head 3 and connected to the contact 15 through an appropriate conductive path. If the vehicle is provided with charging means which is operable to charge the transmitter battery, the charging operation may occur automatically or in response to specific circumstances such as doing something to cause the charging means to be active or operable on the relevant battery. By way of example, the actuator may be exposed to an energy field when located adjacent the vehicle ignition switch.
  • the field may be electronic, magnetic, or electromagnetic, and could be activated in any appropriate manner, such as by operation of the ignition switch, or by insertion of the ignition key into the ignition key slot. Simple exposure to the energy field may be sufficient to provide adequate energy for the transmitter to be able to generate the coded signal. Alternatively, or additionally, ' the energy field may function to automatically charge the transmitter battery during use of the relevant vehicle.
  • the vehicle may be provided with a device which physically mates with the actuator in such a way as to enable effective operation of the actuator.
  • the actuator housing may have a contact which is engageable with a contact of the aforementioned device so as to enable passage of energy through the device to the transmitter.
  • the contacts may be of any suitable form such as cooperable plug and socket -8- contacts. In the latter event, one or both of the contacts may be provided on an end of a flexible conductor lead.
  • the actuator housing or part of that housing, may be located within a recess or cavity provided within the vehicle, and by that location causes the two contacts, whatever their form, to engage. Passage of energy through the engaging contacts may occur automatically, or in response to operation of an associated control switch.

Abstract

Un système de sécurité de véhicule (11) est validé ou invalidé au moyen d'un signal radioélectrique généré par un dispositif portatif (1) situé à un endroit éloigné du véhicule (8). Le dispositif portatif (1) comprend un émetteur (4), une batteire (6) pouvant fournir une source d'énergie à l'émetteur (4), et un commutateur (7) que l'on actionne pour connecter l'émetteur (4) et la batterie (6), générant ainsi un signal codé. Le système comprend un circuit de signal secondaire (21) établi par fermeture de deux contacts (15, 16), l'un (15) situé sur le dispositif portatif (1) et l'autre (16) sur le véhicule (8). La fermeture des contacts (15, 16) a également pour effet de connecter l'émetteur du dispositif (4) à la batterie du véhicule (20), fournissant ainsi une source d'énergie à l'émetteur (4) de façon qu'un signal codé soit généré et transmis le long du circuit de signal secondaire (21). Un signal ainsi généré provoquera l'invalidation du système de sécurité (11). Le dispositif portatif (1) peut faire partie de la clé de contact du véhicule.
