`
`REMOTELY ACTIVATED AUTOMOBILE
`DISABLING SYSTEM
`
`FIELD OF THE INVENTION
`The present invention relates to remotely operated
`system for disabling an automobile, and more particu
`larly to such systems that allow either the owner of a
`vehicle or the police to selectively disable a vehicle
`after it has been stolen or otherwise misappropriated.
`
`BACKGROUND OF THE INVENTION
`Automobile theft is a very common crime, resulting
`in higher automobile insurance rates for all drivers.
`Each year newer and more sophisticated anti-theft de
`vices are manufactured in the hope that these devices
`will prevent the theft of some automobiles. Unfortu
`nately, automobile thieves adapt quickly. No sooner has
`a new anti-theft device been developed, than an auto
`mobile thief has thought of a way to disable or circum
`vent the anti-theft device and steal the automobile.
`Many stolen automobiles are stolen for pro?t,
`wherein the automobiles are sold by the thieves or the
`automobile is stripped of its valuable component parts.
`However, some automobiles are stolen for alternative
`motives such as “joy riding” or the automobile may be
`used in the commission of another crime.
`When an automobile is stolen, the owner of the vehi
`cle usually reports the theft to police. The description of
`the automobile and its license plate number are then
`identi?ed in the police records as being a stolen vehicle.
`Often police locate the stolen vehicle while it is still in
`the possession of the automobiles thieves. If the automo
`bile is being driven when it is identi?ed by police, the
`thieves may try to outrun the pursuant police, resulting
`in a dangerous high speed chase.
`.
`The present invention system helps to both prevent
`automobile thefts and prevent high speed chases by
`allowing both the owner of the automobile and the
`police to disable the automobile remotely after it is
`stolen. Since the disabling device is not activated until
`after the car is stolen, thieves do not know that the
`disabling device is present and do not attempt to discon
`nect the system when they are stealing the automobile.
`After an automobile is stolen the owner may not realize
`that his/her automobile has been stolen until the auto
`mobile is many miles away. The present invention sys
`tem utilized mobile telephone technology to deactivate
`the stolen automobile. With such a system the owner of
`the car need only dial the disabling code for the auto
`50
`mobile into a phone and the code will be transmitted to
`all points within the mobile telephone cellular region,
`which may encompass hundreds of square miles. If the
`automobile is ?rst found by police, the police may dis
`able the automobile by dialing the same disabling code
`into a telephone. Alternatively, the police may also
`transmit the disabling code from small transmitters car
`ried in the police cars. This would allow the police to
`selectively disable a car, involved in a high speed chase,
`at a point most opportune to prevent injury and/or
`property damage.
`Remote controlled devices that disable an automobile
`are in common use. The most typical device is incorpo
`rated into an alarm system, wherein the owner of the
`vehicle has a low power, short range transmitter that
`disables the car and activates an alarm. Such systems are
`exempli?ed in U.S. Pat. Nos. 4,691,801 to Mann, et al.;
`4,159,467 to Ballin; 3,987,408 to Sassover, et al.; and
`
`55
`
`60
`
`65
`
`40
`
`45
`
`2
`4,740,775 to Price. With all of these devices the thief
`will know the car is disabled as the thief is stealing the
`car, giving the thief an opportunity to circumvent the
`device.
`High powered, long distance disabling devices that
`do not disable an automobile until after it is stolen are
`exempli?ed in U.S. Pat. No. 4,067,411 to Conley, et al.
`In such device the automobile that has been stolen re
`sponds to a signal transmitted from a central transmit
`ter. The automobile then disables itself if it is in the
`range of the transmitter. With such disabling systems
`the range is limited and the individual owner cannot
`disable the automobile. Similarly, the police must also
`use the central transmitter and cannot selectively dis
`able the automobile at will.
`Many anti-theft devices also place transmitters into
`automobiles. With such a system, the automobile can
`remotely alert the owner that the automobile is being
`stolen, or may transmit a signal so that the police may
`locate the automobile. Examples of such systems are
`shown in U.S. Pat. Nos. 4,673,921 to Saito et al;
`4,523,178 to Fulhorst; 4,218,763 to Kelly et al; 3,665,312
`to Jarvis: and 3,646,515 to Vodehnal. With such trans
`mitting devices the owner or police can track the loca
`tion of a stolen vehicle but cannot selectively disable the
`car at an unknown location.
`It is therefore an object of the present invention to
`create a remotely activated automobile disabling device
`wherein an owner of a vehicle can dial a disabling code
`into a telephone and disable the vehicle at any point
`within the range of a mobile telephone network. Addi
`tionally, the police can selectively transmit the disabling
`code from transmitters within their squad cars, dis
`abling stolen cars that may be involved in the commis
`sion of a crime or a high speed chase.
`
`SUMMARY OF THE INVENTION
`The present invention system provides a system
`through which a stolen, or otherwise misappropriated,
`vehicle ca be remotely disabled- by either its owner or
`the police. Stated in general terms, the present invention
`includes a receiver that is activated by theft detection
`sensors when the automobile is stolen. Once activated
`the receiver monitors the signal frequency range cur
`rently used to transmit mobile telephone communica
`tions. Once the owner of the automobile discovers that
`the automobile has been stolen, the operator dials a
`predetermined telephone number corresponding to the
`receiver. The number is then transmitted from the sig
`nal towers of the mobile telephone network in use. The
`receiver receives the transmitted signal and compares it
`to a disabling code and an enabling code stored within
`the receiver. If the transmitted signal matches the dis
`abling code, the automobile is disabled. Similarly, if the
`transmitted signal matches the enabling code, a disable
`automobile will be enabled and can resume normal use.
`The enabling and disabling codes can also be trans
`mitted over short distances by portable transmitters
`carried in police vehicles. The portable transmitters
`allow the police to selectively disable a vehicle at an
`opportune moment, if the vehicle is involved in the
`commission of a crime or a high speed chase. Similarly,
`the portable transmitters allow police to enable cars that
`have been disabled in traf?c by the owner of the vehi
`cle.
`The present invention system optionally comes
`equipped with a transmitter. The transmitter can signal

`device 30 would be positionable with a receptacle 32,
`dedicated within the automobile to hold the portable
`receiver device 30. The receptacle 32 has a presence
`sensor 34 located within it that detects whether the
`portable receiver device 30 is present within the recep
`tacle 32 or has been removed by the operator of the
`automobile.
`Referring to FIGS. 1 and 2, the operation of the
`present invention remote disabling system can be de
`scribed. When the operator of the automobile is leaving
`the automobile, the operator removes the portable re
`ceiver device 30 from-its receptacle 32 and takes the
`portable receiver device 30 With him or her. The re
`moval of the portable receiver device 30 from the re
`ceptacle 32 triggers the presence sensor 34, which ena
`bles the theft sensors 12. If the portable receiver device
`30 were not part of the present invention system, the
`theft sensors 23 could be enabled from a toggle switch,
`the removal of the key from the ignition or any other
`well known means through which automobile alarm
`systems are activated.
`The theft sensors 12 monitor the condition of the
`automobile. If triggered by theft or tampering, the theft
`sensor 12 enables the receiver 14. The receiver 14 is
`coupled to an antenna 38 so as to receive signal codes 40
`from a source external of the automobile. The receiver
`14 may take several forms. The receiver 14 may be
`hidden from view and may be coupled to an antenna 38
`that is also hidden from view. Hidden components pre
`vent thieves from disabling the receiver 14 by damaging
`the receiver 14 itself or the antenna 38 coupled to the
`receiver 14. In alternate embodiments the receiver 14
`may be part of a mobile telephone that has been previ
`ously installed in the automobile. In such an embodi
`ment the receiver 14 would be obvious and be coupled
`to the antenna 14 dedicated to the mobile telephone.
`However, thieves would not consider a mobile tele
`phone as an anti-theft device and would not damage
`either the telephone receiver unit or the antenna be
`cause both are valuable commodities to a thief. Regard
`less, to the embodiment of the receiver 14 and the an
`tenna 38, the receiver 14 scans the frequency range of
`mobile telephone transmissions, which is in the range of
`900 MHz. The signal codes 40 received by the receiver
`14 are forwarded to the control unit 16.
`The theft sensors 12 are optionally coupled to a trans
`mitter 28. Once activated the transmitter 28 transmits a
`signal 42 that can be received by the portable receiver
`device 30. The portable receiver device 30 then gener
`ates an audio and/or visual signal that informs a person
`in possession of the portable receiver device 30 of the
`tampering or attempted theft of the automobile.
`The receiver 14 can receive a signal code 40 from one
`of two sources. First, the signal code 40 may come from
`mobile telephone signal transmitter 46 operating in the
`area of the automobile. Such mobile telephone signal
`transmitters 46 are now commonplace in populated
`areas and are easily accessed. Mobile telephone signal
`transmitters 46 are often parts of larger mobile tele
`phone networks, often called “cellular networks" that
`transmit signals across thousands of square miles and
`many encompass several states. A signal code 40 is
`transmitted to the receiver 14 as if the receiver 14 were
`a common mobile telephone unit. The transmission of a
`dialed code to a speci?c mobile telephone being a well
`known technology in the art of telecommunications. To
`transmit the signal code 40, a person, by using any tele
`phone 48, need only dial the phone number of the re
`
`DETAILED DESCRIPTION OF THE
`DRAWINGS‘
`Although the present invention can be used to re
`motely disable any motor vehicle, such as tractor trail
`ers, motorcycles and the like, it is especially suitable for
`use in passenger automobiles. Accordingly, the present
`invention will be described in connection with a passen
`ger automobile.
`Most factory equipped automobiles are not manufac
`tured with an integral anti-theft alarm system. How
`ever, most passenger automobiles do have certain cir
`cuits that can act as theft detection sensors. For exam
`ple, most automobiles have courtesy lights that light
`whenever a door of the automobile is opened, or a trunk
`lamp that lights when the trunk is opened. When an
`anti-theft alarm system is installed on an automobile, it
`is common to couple the alarm system to these existing
`circuits. As such, the courtesy light and trunk lamp
`switches of an automobile act as anti-theft sensors for
`the newly installed alarm system. Alarm systems may
`also add new anti-theft sensors, such as vibration detec
`tors and sound detectors. The combination of existing
`circuitry and new anti-theft sensors combine to give the
`greatest theft detecting protection possible to an auto
`mobile.
`The adaption of anti-theft alarm systems to existing
`automobile circuits and other tampering detection de
`vices is well known in the art. As such, the circuitry
`involved in triggering an anti-theft alarm system is not
`be set forth herein at length. Referring to FIG. 1, the
`automobile circuits and other well known devices com
`monly used to trigger anti-theft alarms are referred to
`herein as theft sensors 12 and are assumed to be part of
`the automobile on which the present invention system is
`to be installed.
`With the theft sensors 12 in place, a receiver 14, con
`trol unit 16, and a means for accessing the control unit
`16, such as a keypad 18, are added to the automobile.
`The control unit 16 is coupled to either the electrical
`circuits or the electromechanical components that se
`lectively control the operation of the starter 20, ignition
`system 22 and emergency lights 24. Optionally, the
`control unit 16 may also be coupled to an externally
`visible device such as the lights 26 surrounding the
`license plate. The controlled activation and deactiva
`tion of such electrical circuits and electromechanical
`components, by a central control unit, is a technology
`that is well known in the art of automobile anti-theft
`devices.
`Optionally, a transmitter 28 and a portable receiver
`device 30 may be added to the automobile. The portable
`receiver device 30 would be located within the automo
`bile so as to be easily accessed and removed by the
`automobile's operator. Preferably the portable receiver
