Description:FIELD OF INVENTION
[001] The present invention relates to a locking system for a vehicle, and in particular the present invention relates to a biometric enabled ignition lock system for two wheeler vehicle in order to prevent theft and improvising security of the vehicle.

BACKGROUND OF THE INVENTION

[002] The locking system in a vehicle must grant access only to authorized persons. The locking system is the means via which handle lock & initiation of the electric powertrain is operated. But, typically, available locking system are simply unlocked by a key and does not required authorization of the owner. Therefore, such unlocking system is not ensuring safety of the vehicle.

[003] However, the majority of biometric enabled switches currently in use are used in large-volume logistics locks, security door locks, handle locks in vehicles etc. Also, available biometric authentication system with complex circuits requiring additional electronic component which increases area or volume of the system. The challenge in the rapidly expanding application of biometric enabled switches is ensuring that the biometric enabled switches may be made smaller while still incorporating an abundance of electronic components.

[004] Also, at present the locking system with biometric electronic keys are available in the market, but in case the lock is destroyed there is no use of biometric electronic key. Therefore, the vehicle may be easily subjected to theft.

[005] The patent application JP2000352245A titled “Vehicular electronic key device” discloses about a system and method certify an electronic key and a driver, and to reduce a load of an arithmetic processing unit of a vehicle in a vehicular electronic key device. Living body information and preset code data on a small number of specific drivers are stored in an electronic key, the living body information and the code data stored in this electronic key are read, living body information on an actually driving driver is acquired by living body information acquiring means preset code data stored on the vehicle side is compared with the code data stored in the electronic key, and when both code data coincide with each other, the living body information on the actually driving driver is compared with the living body information stored in the electronic key, and when both living body information coincide with each other, an engine starting permitting signal is outputted.

[006] The patent application JP2007276595A titled “Vehicular security device, and vehicular security system” discloses about a vehicular security device, and a vehicular security system capable of reducing the power consumption. The vehicular security device comprises an immobilizer ECU, a remote security ECU, a display, an operation unit, and a power supply control unit. The immobilizer ECU controls the drive prohibition and the drive permission of an engine based on the identification signal to be transmitted from a key and/or the remote set signal/remote unset signal to be output from the remote security ECU. When the remote set signal is transmitted, and an immobilizer is set, and if the normal identification signal is transmitted from the key, the power supply state is shifted to be ACC-ON or IG-ON by the power supply control unit, and the setting of the remote immobilizer can be released by the display and the operation unit.

[007] The above mentioned prior art and the available literature describes about the security system having electronic key with biometric identification which enables the driver to unlock the vehicle only on successful verification of real time biometric details to pre stored biometric details. But, the available security system fails to provide security in case the lock is break or tampered.
[008] Therefore, keeping in view the problem associated with the state of the art there is a need for security system for the vehicles which does not allow to start by disabling the engine. Also, the security system must be precise, efficient and reliable.

[034] Further, the control unit (106) process the received biometric information. Further, the control unit (106) compare the processed biometric information with stored biometric information. Further, the control unit (106) verify the processed biometric information by comparing the processed biometric information with stored biometric information using machine learning algorithm. On successful verification the control unit (106) activates the electronic switch (108) by sending a positive signal to the electronic switch (108). Further, the electronic switch (108) are binary devices which are either in completely on state or completely off state. Further, the completely on state of the electronic switch (108) indicates close position of the electronic switch (108) and completely off state indicates in open position of the electronic switch (108).

[035] Further, the electronic switch (108) include but not limited to metal-oxide-semiconductor field-effect transistor (MOSFET) and diode. On activation of the electronic switch (108) the current start flowing from the ignition lock and the ignition lock is also activated. The ignition lock is a turn style lock that couples to a back of an ignition cylinder and switches on the power to the vehicle and allows the vehicle to start and move.

(100) while using the vehicle for the first time. Before the fingerprint is fed, the vehicle is running without the biometric authentication. The first time user feed the biometric information for five times in the fingerprint sensor (102). After every impression, the fingerprint sensor (102) beep once indicating the acceptance of the biometric information.

[039] Figure 2 illustrates a flow chart (200) of method of operation of the biometric enabled ignition lock system. Further, the method comprising, at first step, the biometric information is collected through the fingerprint sensor (102). At second step, the fingerprint sensor (102) read the collected information. At third step, the collected information is transmitted to the control unit (106). At fifth step, the control unit (106) activates the electronic switch (108) on successful verification of the biometric information. At Sixth step, the ignition lock activates in order to start the vehicle. In case the collected information is not verified, at step fourth, the electronic switch (108) remain in off state and the vehicle does not started.

[040] Further, the control unit (106) activates antitheft module (110) in case the collected information is not verified, at step fourth. Further, the antitheft module (110) activates an alarm, disabling the scooter's ignition system, or both, depending on the desired level of security.

After capturing and processing the fingerprint data, if the control unit (106) determines that the captured fingerprint does not match any of the stored templates, it recognizes this as an authentication failure. Upon detecting an authentication failure, the control unit (106) triggers the activation of the antitheft mechanism. This mechanism could involve activating an alarm, disabling the scooter's ignition system, or both, depending on the desired level of security. Further, the system is configured with safety features such as timeout mechanisms, error handling, and backup methods for starting the vehicle in case of sensor failure or emergency situations.
