SECURITY SYSTEM FOR VEHICLE
BIELD OF THE INVENTION
[0001] The present invention relates to security systems for vehicles.
BACKGROUND
[0002] There are many security systems available to prevent vehicle theft, but
as a matter of fact thefts have not been stopped. In some instances, ridersldrivers
are threatened and the vehicles are stolen. There are conventional vehicle tracking
systems that track a vehicle once the vehicle is stolen. One of the vehicle tracking
system known in the prior art is a system that tracks a vehicle using a mobile
device, for example, a mobile phone, after the theft of the vehicle has occurred.
For instance, when a vehicle is stolen, the vehicle owner can initiate vehicle
tracking using a Global Positioning. System (GPS) module. Once the vehicle is
located, local .law enforcement resources are dispatched to the vehicle's location.'
However, even if location of the vehicle is tracked, the vehicle is still mobile and
the vehicle may move somewhere else from the last tracked location, before the
law enforcement reaches the vehicle's tracked location. Accordingly, even by
usage of such vehicle tracking systems, the vehicle owner andlor the local law
enforcement can only, at best, know the location of the vehicle, but cannot prevent
the movement of the vehicle.

DETAILED DESCRIPTION
[0022] While the invention is susceptible to various modifications and
alternative forms, an embodiment thereof has been shown by way of example in
the drawings and will be described here below. It should be understood, however
that it is not intended to limit the invention to the particular forms disclosed, but
on the contrary, the invention is to cover all modifications, equivalents, and
alternative falling within the spirit and the scope of the invention.
[0023] The terms "comprises", "comprising", or any other variations thereof, are
intended to cover a non-exclusive inclusion, such that a setup, device or method
that comprises a list of components or steps does not include only those
components or steps but may include other components or steps not expressly
listed or inherent to such setup or.device or method. In other words,.one or more
elements in a system or apparatus proceeded by "comprises ... a" does not,
without more constraints, preclude the existence of other elements or additional
elements in the system or apparatus.
[0024] For the better understanding of this invention, reference would now be
made to the embodiment illustrated in the accompanying figures and description
here below, further, in the following figures, the same reference numerals are used
to identify the same components in various views.
[0025] Figure 1 illustrates a block diagram of a security systenl (100) for a
vehicle (not shown), according to an embodiment. The security system (100)
comprises an ignition control system (1 lo), a vehicle ignition unit (102) and at
least one communication device for example, a mobile device (1 12). The ignition
control system (1 10) further comprises an ignition control module (104) and a
comn~unication module (106). \Vithout limiting to the scope of the present
invention, in an embodiment, the communication module (106) includes a
Subscriber Identity Module (SIM) card (108) to communicate to any other
communication devices. For instance, the communication module (106) may use
Global System of Mobile (GSM) network technique to communicate with other
communication devices. Alternatively, the communication module (106) may not
include the SIM card (108), and can still communicate with other communication
devices. For instance, the communication module (106) may use code division
multiple access (CDMA) network technique to communicate with other
communication devices. Additionally or optionally, the communication module
(106) may also communicate using Internet from Wi-Fi techniques, and from
other means.
[0026] The ignition control system (1 10) is adapted to control the vehicle
ignition unit (102) of the vehicle. In an embodiment, the vehicle ignition unit
(102) comprises, among other components, an ignition coil and a spark plug. The
ignition control module (104) is electronically and communicatively coupled to
the communication module (1 06). In an embodiment, the communication module
(106) comprises a provision for applying the SIM card (108), for example, by
connecting / inserting the SIM card (108) in a slot provided in the communication
module (106). In an embodiment, the ignition control module (104) and the
communication module (106) are integrally connected and mounted on a same
circuit board or a chipset, for example, a printed circuit board (PCB) inside a
'. housing. For example, a PCB, on which the ignition control module (104) and the
communication module (106) are .integrally mounted, is packaged in a single premoulded
plastic housing. For the purposes of this description, the housing
comprising the ignition control .module (104) and the communication module
(1 06) is shown as ignition control system (1 10) as shown in Figures 1 and 4. In an
embodiment, the ignition control module (104) is a Capacitor Discharge Ignition
(CDI) system.
I microprocessor or any similar progran~mable devices. For exanlple, the ignition
I control module (104) may be embodied as one or more of various processing
devices, such as a coprocessor, a microprocessor, a controller, a digital signal
processor (DSP), a processing circuitry with or without an accompanying DSP, or
I various other processing. devices comprising integrated circuits such as, for
example, an application specific integrated circuit (ASIC), a field programmable
gate array (FPGA), a microcontroller unit (MCU), a hardware accelerator, a
. special-purpose computer chip, or the like. The ignition control module (104) can
comprise either single control unit or multiple control units as each of the control
units being electronically connected with each other to transmit data there
between.
[0028] It should be understood that the ignition control module (104) and the
communication module (106) are integrally connected and mounted on the same
base PCB, therefore, it is impossible to separate the communication module (1 06)
from the base PCB, thereby making it impossible to operate the ignition control
module (104) by bypassing circuitry of the communication module (106). For
example, it is impossible for an unauthorised user to operate the ignition control
system (1 10) by a known technique generally referred to as "hot wire". In an
embodiment, the ignition control module (104) checks for an identity (or
presence) of the communication module (106) before enabling the vehicle ignition
unit (102). In an embodiment, the identity of the communication module (106)
may be a unique identificationcode of the communication device, for example, an
International Mobile Station Equipment Identity (IMEI) code of the
communication module (106) or any other form of international serial number of
the communication module (1 06).
[0029] In the embodiment where the communication module (106) cohprises
the SIM card (108), a unique identification code of the SIM card (108) may also
serve as the identity for the communication module (106). In an embodiment, the
unique identification code of the SIM card (108) is an Integrated Circuit Card
9
P :, ...,' .. ., . qEL.@z. -, ,. 7. - 5$ 6 .$ 6
Identifier (ICCID) code and/or lnternational Mobile Subscriber Identity (IMSI)
number. The ignition control module (104) identifies a SIM card by the ICCID
code. Additionally, there is provided a unique identification code for the
communication module (106) of the ignition control system (1 10): and it may also
be the unique identification number for the ignition control system (1 10). In an
embodiment, the unique identification code is the IMEI code. In an embodiment,
the unique identification code of the communication module (106) is used by the
mobile device (1 12) for communicating with the communication module (106).
For example, in an embodiment, the IMEI code of the communication module
(106) is used for communicating with the communication module (106) by the
mobile device (1 12). Further, the ignition control system (1 10) is coupled to the
vehicle ignition unit (102) of the vehicle. The communication module (106) is
adapted to communicate with ,the at least one mobile device (e.g., the mobile
device (1 12)) through a communication network (1 14).
[0030] Without loss of generality, example of the communication network
(1 14) is a Global System of Mobile (GSM) network. However, other examples of
t the communication network (1 14) may include, other second-generation (2G)
I wireless communication networks such as IS- 136 (time division multiple access
I (TDMA)) and IS-95 (code division multiple access (CDMA); a third-generation
(3G) wireless communication network such as Universal Mobile
Telecommunications System (UMTS), CDMA1000, wideband CDMA
(WCDMA) and time division-synchronous CDMA (TD-SCDMA); a 3.9G
wireless communication protocol such as evolved universal terrestrial radio access
network (E-UTRAN)', and a .fourth-generation (4G) wireless communication
protocols such as LTE (Long-Term Evolution), or the like. In an example, the
communication module (106) may communicate with the at least one mobile
device (1 12) via a General Packet Radio Service (GPRS) network service.
[0031] Figure 2 illustrates a flowchart outlining a process 200 of activation of
the security system (100) of the vehicle, according to an embodiment of the
present invention. It should be noted that to facilitate discussions of the flowchart
10
~,,...,. .> .a E..o ,;:- , : .... 5... ...& ,-.07- 8.Q.41;.-5 . k.6 :Z,G.
of Figure 2, certain operations are described herein as constituting distinct steps
performed in a certain order. Such implementations are examples only and lionlimiting
in scope. Certain operation may be grouped together and performed in a
single operation, and certain operations may be performed in an order that differs
from the order employed in the examples set forth herein. Moreover, certain
operations of the process 200 are performed in an automated fashion. These
operations may involve siihstantially no interaction with the user. Other
operations of the process 200 may be performed by in a manual fashion or semiautomatic
fashion. These operations may involve interaction with the user via one
or more user interface presentations.
[0032] The process 200 starts from step 201. In step 202, a primary SIM card
(e.g., the SIM card (108)) is applied to (e.g., connected to or inserted into) the
communication module (1 06). In step 204: the ignition control module (1 04)
receives data associated with the SIM card (108). upon applying the SIM card
(108) to the communication module (106). In an embodiment, the data associated
with the SIM card (108) is the ICCID code of the SIM card (108). In step 206, the
received data is stored in a memory of the ignition control module (104). The
ignition control module (104) checks for the ICCID code of the primary SIM card
each time. the vehicle is started and verifies this with the ICCID code stored in the
memory of the ignition control module (104). In another embodiment, where there
' is no SIM card, the memory of the ignition control module (104) stores the
identity of the communication module (106), for example, the IMEI, an
international serial number, or the like.
[0033] In step 208, a 'mobile registration command' is received at' the
communication module (106) from the mobile device (1 12) for registering one or
more mobile devices to operate the security system (100) of the vehicle. In an
embodiment, the mobile registration command may be received in form of an
SMS or other forms of messaging (e.g., push notification) from the mobile device
(1 12). For example, the SMS sent from the mobile device (1 12) for registering
two mobile devices contains a command (C) in the following format:
11
E,::: P. O,. D,..:. ,,.E. . ,.,h-, .F . :, i..T .. , . .3-., $.,'I -Oti' 7-.2@.1!5 J. 6.. .1 , 96.
wherein the IMEI is an IMEI code of the communication module (106) of the
ignition control system (1 10) of the vehicle. Therefore, the above command (C) is
for registering two mobile devices whose numbers are +9 19091 1 1 1 1 1 1 and
+9 19092222222. In step 2 10, the received command (C) is authenticated / verified
by the ignition control module (104). In step 212, upon authentication of the
received command (C). the one or more mobile devices are registererl a<
authorised mobile device(s) by the ignition control module (1 04) for operating the
security system (100) of the vehicle. For example, mobile devices with mobile
numbers +9 1909 1 1 1 1 1 1 1 and +9 19092222222 constitute the one or more
authorised mobile devices for operating the security system (100) of the vehicle,
and in step 214, the security system (100) of the vehicle is enabled for operation.
Thereafter, the process 200 of activation oft the security system (100) of the
vehicle terminates at step 2 15.
[0034] Figure 3 illustrates a flowchart of a process 300 outlining operation of
the security system (loo), according to an embodiment of the present invention.
The process 300 starts from step 301. In step 302, vehicle theft is detected by a
user. In an embodiment, the user may detect the vehicle theft based on the
information provided by a theft detecting means. In an embodiment, a signal in
the form of a command is sent as SMS to the one or more authorised .(or
registered) mobile devices by the communication module (1 06) intimating that the
vehicle is attempted to start. If such attempt is not by the user or with the user's
permission, the user can determine that the vehicle is under potential theft. In an
embodiment, otherwise, the user is readily aware of the vehicle theft, such a
situation could be encountered when the user himselfherself is threatened and the
vehicle is stolen. In step 304, an ignition disable signal representing an ignition
disable command is received by the communication module (106) of the ignition
control system (1 10) as sent by the user through the mobile device (1 12). In an
example, the mobile device (1 12) may be any of the one or more authorised
mobile devices. In another esaniple, the ignition disable signal may also be sent
by the user from a mobile device that is not an authorised mobile device.
[0035] In step 306, the ignition control module (104) determines whether the
mobile device (1 12) from which the ignition disable signal was sent is an
authorised mobile device or not. The mobile device (1 12) is the authorised mobile
device, iff it is from among the one or more authorised mobile devices that are
registered with the security system (100) as described with reference to Figure 2.
In an embodiment, the ignition &sable signal in the form of an ignition disable
command is sent as SMS by any of the one or more authorised mobile devices.
For example, the SMS sent from a registered (or authorised) mobile device
contains an ignition disable command in a specific format as:
"BIKEIMMOBILIZE".
If it ,is determined that the mobile device (1 12) is an authorised mobile device
(e.g., being one. of the one or more authorised (registered) mobile devices), the
process 300 moves to step 308.
[0036] In step 308, the ignition control module (104) detects one or more
vehicle state parameters. In step 3 12, the ignition control module (1 04) determines
whether all the parameters among the one or more vehicle state parameters satisfy .
a pre-determined vehicle state condition. In a non-exhaustive example, the one or
more vehicle state parameters include an engine operating Revolution per Minute
(RPM) and the pre-determined vehicle state condition is "engine operating RPM
should be less than a pre-determined engine RPM. In an embodiment, the predetermined
engine RPM is an idle RPM of the engine. If the detected one or more
vehicle state parameters do not satisfy the pre-determined vehicle state condition,
then the process 300 moves to step 308. If the detected one or more vehicle state
parameters satisfies the pre-determined vehicle state condition, then the process
moves to step 314. In step 3 14, the ignition control module (104) disables at least
one engine running means of the vehicle, and subsequently the process 300 ends
at step 317. In an embodiment, the at least one engine running means of the
vehicle is the vehicle ignition unit (102). 1n.m embodiment: it is ensured that thc
vehicle is immobilised.
[0037] If in the step 306, the ignition control module (104) determines that
mobile device (1 12) is not an authorised mobile device then the process 300
moves to step 3 10. In step 3 10, the ignition control module (104) determines
whether the ignition disable signal sent from the mobile device (1 12) is an
authorised signal. In an embodiment, the authorised signal represents one or more
pre-determined authorised commands. For example, the ignition disable signal (in
form of SMS) sent from an unregistered/unauthorised mobile device may be in
form of a pre-determined authorised command in the following format:
- "Super passwordBIKEIMMOBII:IZE".
If in step 3 10, it is determined that the ignition disable signal sent from the mobile
device (1 12) is the authorised signal, then the process 300 moves to the step 308,
already described above. If the ignition disable signal is not determined as the
authorised signal, then the process 300 moves to step 316. In step 316, the
security system (I 00) of the vehicle does not take any action, and the process 300
ends at the step 3 17.
[0038] Figure 4 depicts an ignition control system (1 10) of the vehicle,
. according to an embodiment. The ignition control system (1 10) includes a housing
.. (404), a communication module, an ignition control module (the communication
module and the ignition control module are not visible in Figure 4), a socket
(402), a base 'printed circuit board (PCB) (4.10) with circuitry for electrically
interconnecting the ignition control module and the communicatioli module to
perform the function of the ignition control system (1 10). Without loss of
generality, in an embodiment, the housing (404) is a rectangular shape housing.
The base PCB (410) is disposed in the housing (404) and a small portion (see,
406) of the base PCB (410) is visible from one comer of the housing (404) and
exposed outside. The socket (402) includes one or more input-output (110) pins in
electrical contact with the electronic circuitry in the base PCB (410) for
electrically connecting the ignition control system (1 10) to the 'vehicle ignition
14
unit and a power source (the vehicle ignition unit and the power sourcc not visiblc
in Figure 4) of the vehicle. In an embodiment, a SIM card is removably positioned
in a slot (408) provided in the small portion (406) of the base PCB (410). As the
small portion (406) of the base PCB (4 10) is exposed to the outside, the SIM card
can be easily removed or connected to the base PCB (41 0). In an embodiment, the
SIM card is permanently fixed to the base PCB (410) and the housing (404) is
completely sealed. As the housing (404) is completely sealed, t h e r ~ f n r ~it, is
impossible for extraneous element such as dust, water to enter into the housing
' (404).
[0039] It would be appreciated by those skilled in the art that in various
- . . ....-.-
embodiments of the security system (100) of the present inOeXfion, the ignition
control module (104) and the communication module (106) are integrally
connected and mounted on the same base PCB and are inseparable. Therefore, it
is impossible for a thief to steal the.vehicle, as there is no means to operate the
ignition control system (1 10) while bypassing the circuitry of the communication
module (106).
