DESC:FIELD OF INVENTION:
[001] The present invention relates to the field of anti-theft systems and more particularly relates to the anti-theft systems used for preventing vehicle theft.

BACKGROUND OF INVENTION:
[002] With the advancement of technology especially in automotive field the vehicle are becoming much more advance and luxurious which has resulted in increase in the price of the vehicles. There is a clear trend towards increasing number of people buying expensive two-wheeled and four wheeled vehicle. As buyer’s ability to purchase the expensive vehicles is increasing, their expectation about security and safety features in the vehicle is also increasing. The buyers expectations related to security is not only in the expensive vehicle but also in non-expensive vehicles. The vehicle theft is a major problem and more prone in two-wheeled vehicles as it is comparatively easy to steal two-wheeled vehicle as compare to four-wheeled vehicle due to various reasons, for example ease of accessibility to ignition switch, handle bar lock etc. Therefore, this becomes a strong customer requirement regarding security features primarily in two-wheeled vehicle.

[003] The common technique for stealing the vehicle is by hot-wiring or short-circuiting of the cables coming out from ignition switch. Ignition switch acts as a circuit-closing element for completing the power supply circuit from battery to the ignition means of the engine. When the ignition switch is closed by rotating the ignition key, the power circuit gets complete and it enables starting of engine. Any person can tamper this circuit by hot wiring or short-circuiting. This is done by bypassing the ignition switch and thus power or current is directly supplied from battery towards engine ignition means without use of ignition switch. As all cables, are open in case of two-wheeler it is easy to do hot wiring or short-circuiting of cables. If the handlebar is locked then it may be easily broken by applying some force.

[004] Few of the systems available in the market are purely alarm based however; the alarm may be easily disabled by thief while stealing the vehicle. Hence purely alarm based system are not much of use and inadequate. Another system available is based on wireless communication comprising a transmitter and receiver wherein; the transmitter is fitted in an ignition key, which transmits a signal, which is received by the receiver mounted in vehicle. If the received signal is correct then it authenticates to start the vehicle. However, such systems are very costly.

[005] Therefore, there is a clear need to provide a robust and compact anti-theft system in vehicles, which may not be easily disabled/tampered and adequate to prevent the vehicle theft using hot-wiring of cables. Also, the required system should be affordable/economical.

[008] The control unit authenticates the signal/s of the electronic circuit by comparing one and/or more signal-attributes such as amplitude, frequency, duty cycle, voltage or current of the signal with a pre-determined range of signal attributes and authenticates the signal if the attributes of the received signal/s are within said pre-determined range.

[009] As a further aspect of invention, the electronic circuit and the ignition switch along with said mechanism are mounted/ packaged compactly within an ignition cylinder such that said electronic circuit is not accessible from outside. This helps in providing compact and robust arrangement.

[010] The ignition switch is operated using an ignition key such that when ignition switch is rotated by ignition key to “ON” position, the double pole single throw type switch mechanism completes an electric path in order to simultaneously supply power to both electronic circuit and to the control unit from battery. The electronic circuit generates a signal/s upon receiving power from a battery. The control unit receives the signal/s generated by said electronic circuit and compares the at least one of the signal attributes of the received signal with the pre-determined range of signal attributes such as amplitude, frequency, duty cycle, voltage or current.

The oscillator is preferably provided in the form of an electronic chip, compact in size such that it is accommodated within ignition cylinder. This will restrict the direct exposure of the chip to any third person, which avoid possibility of any tampering to the chip.

[013] The ignition cylinder comprises, an ignition key insertion slot mounted towards top side of the ignition cylinder for inserting an ignition key; a cylindrical rod connected to said key insertion slot and configured to rotate along with said key insertion slot; the electronic circuit is mounted towards bottom part of ignition cylinder; and the double pole single throw mechanism connected to said cylindrical rod and configured to actuate when the cylindrical rod is rotated.

The generation of unique attribute of signal by the electronic circuitry is achieved through programming of said electronic circuitry. According to another embodiment one or more components of electronic circuitry are changed to result in change in one or more signal attributes. The control unit is programmed accordingly to store the pre-determined range of signal attributes such that the attribute of the signal generated by the electronic circuitry matches with said pre-determined range. This makes the anti-theft system foolproof and robust.

[015] The control unit may be a vehicle control unit (VCU), Engine Control Unit (ECU), Capacitor discharge ignition (CDI), Engine Management System (EMS) or any other suitable controller within vehicle and is in communication with the electronic circuit to receive the signal/s generated by electronic circuit. The control unit is configured to authenticate the received signal/s by measuring and comparing at least one of the attribute of the received signal with the pre-stored range of amplitude, frequency, duty cycle, voltage or current. The control unit is further connected with at least one vehicle component related to the systems including oil pump, fuel supply, ignition system or engine starter etc. According to another aspect of present invention, if the control system does not receive any signal from the electronic circuit within prescribed time after rotation of ignition switch to ON position or if the received signal is not within the pre-defined range, then the control unit may not initiate functioning of at least one of the vehicle component thereby preventing the vehicle from starting. The indication of same is provided to vehicle owner through audio, radio or visible indication. Therefore, the proposed system does not allow vehicle to start without verification of signal by the control unit.

[016] The proposed system may be additionally equipped with an alarm wherein the alarm may start if the control unit does not receive authentication signal from the electronic circuit within prescribed time or the frequency of received signal does not match with pre-defined range.

DETAIL DESCRIPTION OF DRAWINGS:
[031] Referring now to Fig.1A and 1B which describes a conventional ignition system according to prior art. The ignition system 100 is illustrated including a single pole single throw type ignition switch 110 with associated electrical circuit 100. The ignition switch 110 comprises a contact 115, which is used to connect the input side 110A of the ignition switch 110 to output side 110B. The input side 110A is connected to the battery 120 using cable 112A and output 110B is connected to at least one control unit such as vehicle control unit (VCU), Engine Control Unit (ECU), Capacitor discharge ignition (CDI), Engine Management System (EMS) or any electrical components used for engine or vehicle function/s (not shown) using a cable 112B. These two cables (112A, 112B) comes out from ignition switch (110). When ignition key (not shown) is rotated the contact (115) of ignition switch gets rotated and closes the electrical path. This completes the electrical circuit and supplies the current from battery (120) to control unit thereby enabling starting of vehicle or engine. During hot-wiring the two cables (112A, 112B) coming out from ignition switch (110) are short-circuited thereby bypassing the ignition switch (110) or key. Hence, vehicle may be started without using ignition key.

[032] In order to avoid the above explained problem of prior art, the present invention provides an ignition switch 200 equipped with anti-theft system which is explained herein below with reference to the Fig. 2 to 6B. According to one of the embodiment of present invention, the single pole single throw type switch is replaced by double pole single throw type mechanism 210 as shown in Fig. 2. Therefore, compare to prior art one additional output 210C is taken from the ignition switch. This output is connected to an electronic circuit 250 configured to generate a signal of a specific attribute parameters such as amplitude, frequency, duty cycle, voltage or current for example 5V,1000Hz and/or 21% duty cycle of PWM signal. Once the ignition key is rotated contact 215 closes two paths i.e. 210B and 210C. First output 210B is connected to electric circuit 250 and the second output goes to the control unit for example, VCU 270. As the ignition switch 210 closes the electric path, power is supplied from battery 220 to both electronic circuit 250 and the control unit 270. Upon receiving a power supply from a battery 220 the electronic circuit 250 generates the authentication signal and is received by the control unit 270 which measures one or more attributes such as amplitude, frequency, duty cycle, voltage or current of the received signal. The electronic circuit 250 is preferably in wired/ physical connection with the control unit 270, though wireless connection is also possible. The ideal or correct range of the parameters of one or more signal attributes are already pre-stored in the control unit 270, which are compared with the parameters of, received signal. If the received signal is within the pre-defined range then the control unit 270 enable functioning of at least one vehicle component (275) for example oil pump, ignition system , starting system of engine or starting fuel supply to engine thereby starting the vehicle. According to another aspect of present invention, if the control unit 270 does not receive any signal from the electronic circuit 250 within prescribed time or if the received signal is not within the pre-defined range, then the control unit 270 may disable any of the said functions of vehicle component 275 thereby preventing the vehicle from start.

[033] Therefore, according to the present system even if the input cable 212A and the cable to control unit 212B are hot-wired, the vehicle will not start as the control unit 270 will not receive authentication signal from the electronic circuit 250. As ignition switch 210 is bypassed, the electronic circuit 250 also gets bypass, which does not receive power to generate the signal. Also in case of any tampering to electronic circuit 250, the received signal by the control 270 will not fall in the pre-defined range and hence the signal will not be validated by the control unit 270, which will prevent the vehicle from start. Therefore, purposely the electronic circuit 250 is fixed inside the ignition cylinder 225 such that it is not accessible to any third person such as thief. This prevents anyone from doing any kind of modifications or tampering in the electronic circuit 250 and therefore provides a completely secured & robust system. The ignition switch having above defined mechanism and the electronic circuitry 250 are mounted within ignition cylinder 225 which results in compact arrangement.

[034] The attributes of the signal generated by electronic circuit 250 is configured to be unique for each vehicle or for a set of vehicles. The generation of signal with unique attribute is achieved through programming of the electronic circuitry 250. For example, an electronic circuit is a microprocessor based circuitry including a switch wherein; the switch is programmed to generate unique frequency of signal for each vehicle.

[035] According to another embodiment of present invention; one or more components of said electronic circuitry 250 is changed to result in generation of signal with unique attributes. For example, the components include register or capacitor of the electronic circuit 250.

[036] The control unit is programmed accordingly to store the pre-determined range of signal frequency such that the frequency of signal generated by the electronic circuit matches or falls within stored pre-determined range of frequency.

[037] The mounting arrangement of electronic circuit 250 is explained herein below with the help of fig. 4. The ignition switch 200 with double pole single throw mechanism 210 is provided in the ignition cylinder 225. The electronic circuit 250 is provided within ignition cylinder 225 for example towards bottom part. A handle bar lock 412 is provided to lock or unlock the handle bar (not shown). Ignition key (not shown) is inserted in a key insertion slot (401) provided on the top portion of the ignition cylinder 225. When the ignition key is rotated toward “ON” position inside ignition slot a cylindrical rod (not shown) gets rotated. This causes the ignition switch 210 to rotate. As the cylindrical rod (not shown) gets rotated the lock bar gets unlocked which allows movement of handlebar. Upon further rotation of ignition key, the contact 215 closes the electric path as explained above. This connects the electronic circuit 250 with battery 220 to start producing the signal. Since the electronic circuit 250 is mounted within ignition cylinder 225 it is not exposed to thieves and thereby protects it from any tampering. The oscillator 250 may be mounted at any location within ignition cylinder 250.

[038] Additionally a system may be equipped with an alarm (not shown) connected to vehicle control unit (270) and starts making an audible sound, visual indication or send wireless signal to indicate an attempt of theft whenever the signal is not received or error is detected in signal. If there is any kind of malfunction in oscillator or control unit or in any part of entire circuitry then same may be indicated to driver through audible or visible signals on the dashboard panel.

[039] Fig. 5 illustrates flowcharts representing the steps involved in the method of protecting the vehicle from theft according to one of the embodiment of present invention. The present invention provides a method of protecting a vehicle from theft comprising steps of: rotating an double pole single throw (DPST) ignition switch mechanism to allow power supply to an electronic circuit and to a control unit from a battery; generating a signal by the electronic circuit upon receiving power from the battery; receiving the generated signal of the electronic circuit by the control unit; authenticating the received signal by comparing at least one of the attribute of the signal including amplitude, frequency, duty cycle, voltage or current of the signal with pre-stored range of amplitude, frequency, duty cycle, voltage or current of the received signal by the control unit; enabling function of at least one of the vehicle component 275 by the control unit in order to start the vehicle if the amplitude, frequency, duty cycle, voltage or current of the received signal is within pre-stored range of frequency, duty cycle, voltage or current.

[040] According to another aspect of present invention, the double pole single throw mechanism may be suitably replaced with other type of switch mechanisms including Single Pole Double Throw (SPDT), Double pole Double Throw (DPDT), Triple Pole Single Throw (TPST) etc.

[041] Fig. 6A and 6B discloses double pole double throw (DPDT) type mechanism comprising two input point/s (605a, 605b) configured to connect to four output points (610, 612, 615, 620) wherein; two output points (615, 620) are connected to the electronic circuitry (250). In ignition OFF condition, the input point (605a) is connected to the first output point at 610, which is a no load point as it is not connected to any electric load. Another input point (605b) is connected to the third output point (615), which is connected to the electronic circuitry (250). During OFF condition, the electronic circuitry (250) is not configured to generate any signal. Third output point (615) acts as a toggle input When the Ignition key is rotated to ON position, the input point (605a) is connected to the second output point (612) thereby connecting the battery (220) to the electric load. Another input point (605b) is connected to the fourth output point (620) of the electronic circuitry (250) thereby connecting the battery (220) to the electronic circuitry (250). During ON condition, the electronic circuitry (250) generates a signal, which is authenticated by the control unit (270) thereby enabling starting of vehicle. Therefore, vehicle authentication is possible only when, the input point (605a) is connected to the output points (612) and (620). This makes stealing of vehicle more difficult as identification of a right combination of input and output points is difficult for a third person. A suitable design of mechanism may be used to achieve the necessary electrical connections.

[042] Fig. 7A and 7B discloses another embodiment of present invention in which a Triple Pole Single Throw (TPST) mechanism is used. In Ignition OFF condition, input points (705) are not connected to the output points (710, 715, 720) hence, the battery (220) is not connected to the electric loads as well as battery (220) is disconnected from the electronic circuitry (250). No signal is generated by the electronic circuitry (250) and the vehicle is not allowed to start. The electronic circuitry (250) is provided with two poles (715, 720) to generate two different signals (PWM1 and PWM 2). As the ignition key is rotated to ON position the input points (705) are connected to the output points (710) as well as to the two poles (715, 720) of the electronic circuitry (250). This enables generation of two different signals (Signal1 and Signal 2) from the electronic circuitry (250). The signal 1 is with different attributes as compared to the signal 2. The control unit (270) receives the signals and further allows starting of the vehicle only when the attributes of both the signals matches with predetermined range of signal attributes stored in the control unit (270). Therefore, the system of present embodiment is more secured as a combination of two different signal attributes are verified before authenticating the use of vehicle instead of verifying a single signal. This also makes stealing of vehicle difficult. The number of signals generated by the electronic circuitry (250) may vary based on requirements.

[043] The present invention is not limited to the type of mechanisms mentioned herein above and any other type of switch mechanisms may be used to achieve the functionality of present invention.

[044] In another aspect of present invention, the present anti-theft system may be applied to an electric or hybrid vehicle wherein the battery is used a power source to drive the vehicle. In such vehicles, the control unit may disable the power supply from battery if the authentication signal is incorrect. Therefore, the present invention is applicable to any vehicle including two-wheeled, three-wheeled or four-wheeled vehicle including electric, fuel operated or hybrid vehicles
