FIELD OF DISCLOSURE
The present disclosure generally relates to anti-theft/ engine immobilizer and vehicle protection systems and methods for vehicles.
Particularly, the present disclosure relates to an immobilizer system for a two-wheeler vehicle such as a motorcycle or a scooter or any other two wheeled vehicle.
BACKGROUND
A two-wheeler vehicle such as a motorcycle or a scooter or any other two wheeled vehicle is generally left unattended at a parking space or any other unsecured area. Further, two wheeled vehicles are easily accessible and can be easily tampered. Accordingly, such two wheeled vehicles are subjected to tampering, vehicle lift, fuel theft, battery theft and other undesirable events. Such events can damage the two-wheeler and lead to financial losses.
Accordingly, there is a need for a security system that may prevent such undesirable events such as vehicle lift, fuel theft, battery theft and other undesirable events. Furthermore, there is a need for an immobilizer system that is economical, effective and reliable. Some of the prior art patent documents that disclose immobilizer systems for immobilizing the two-wheeler vehicle by causing ignition prohibition are as follows:
Indian Published Patent Application 80/KOL/2005 discloses an anti-theft method and device for a vehicle, particularly an immobilizer system for immobilizing a two-wheeler vehicle by causing ignition prohibition. The immobilizer system has a controller which transmits an ignition prohibition cancelling signal to an ignition control unit of an engine when an ID code of a

transponder, built in a key, match an ID code previously registered in the controller on the vehicle.
Similarly, the US Granted Patent US6525433 discloses a method and apparatus of vehicle theft prevention. The method and apparatus of vehicle theft prevention utilizes a key having a transponder bearing an ID and a key cylinder, that is adapted to receive this key and which has an antenna for supplying electrical power to the transponder and receiving an ID signal back from it. This system is stated to permit easy correction of incorrectly set original IDs or the simple substitution of a new key or an old master key as a new master key into a vehicle wherein the lock cylinder must be replaced due to a defect.
Although, the above mentioned prior art documents disclose immobilizing of a vehicle by causing ignition prohibition in case of any undesirable events for preventing vehicle theft, however, such prior art documents do not provide user friendly arrangements and provisions for cancelling the immobilizing action of the immobilizer by an authorized user in case the vehicle is immobilized by the immobilizer.
More specifically, in case of the prior art immobilizing systems, the immobilized vehicle is mobilized by cancelling the immobilizing action of the immobilizer by using an authorization system that is accessible only to the owner of the vehicle or anybody who is authorized by the owner of the two-wheeler vehicle. The authorization system enables cancelling of the immobilizing action of the immobilizer, thereby facilitating driving of the vehicle by the owner of the vehicle.
However, the prior art arrangement fail to check the authenticity of the person before cancelling the immobilizing action of the immobilizer. In most of the prior art immobilizer systems, cancelling the immobilizing action of the immobilizer is performed by a fob element of the authorization system that is in

possession of the owner of the vehicle only, the fob element communicates with the immobilizer system for cancelling the immobilizing action of the immobilizer.
Accordingly, safe handling of the fob element of the authorization system becomes a critical aspect. Most of the prior art immobilizer systems fail to immobilize the vehicle in case of the fob is lost. In such circumstances the owner of the two-wheeler vehicle has to drag the two-wheeler vehicle or use a towing vehicle for transporting the immobilized two-wheeler to the dealer for cancelling the immobilizing action of the immobilizer. Such conditions may be very disturbing for the real owner of the two-wheeler vehicle and may cause a lot of inconvenience to the owner of the two-wheeler vehicle. Accordingly., there is a need for a user friendly immobilizer system for a two-wheeler vehicle.

DETAILED DESCRIPTION
An immobilizer system of the present disclosure will now be described with reference to the embodiments which do not limit the scope and ambit of the disclosure. The description provided is purely by way of example and illustration. The embodiment herein and the various features and advantageous details thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate

an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
A two-wheeler vehicle such as a motorcycle or a scooter or any other two wheeled vehicle is generally left unattended at a parking space or any other unsecured area. Further, the two wheeled vehicles are open and are easily accessible and can be tampered with easily. Accordingly, such two wheeled vehicles are subjected to tampering, vehicle lift, fuel theft, falling down of the vehicle, battery theft and other undesirable events. Such events can damage the two-wheeler and lead to financial losses. Prior art discloses immobilizer systems for immobilizing the two-wheeler vehicle by causing ignition prohibition. However, such prior art documents do not provide user friendly arrangements and provisions for cancelling the immobilizing action of the immobilizer by an authorized user in case the vehicle is immobilized by the immobilizer. More specifically, in case of the prior art immobilizing systems, the immobilized vehicle is mobilized by cancelling the immobilizing action of the immobilizer by using an authorization system that is accessible only to the owner of the vehicle or anybody who is authorized by the owner of the two-wheeler vehicle.
The authorization system enables cancelling of the immobilizing action of the immobilizer, thereby facilitating driving of the vehicle by the owner of the vehicle. However, the prior art arrangement verify the person before cancelling the immobilizing action of the immobilizer. In most of the prior art immobilizer systems, cancelling the immobilizing action of the immobilizer is performed by a fob element of the authorization system that is in possession of the owner of the vehicle only, the fob element communicates with the immobilizer system for cancelling the immobilizing action of the immobilizer.

Accordingly, safe handling of the fob element of the authorization system becomes a critical aspect. Most of the prior art immobilizer systems fail to immobilize the vehicle in case of the fob is lost. In such circumstances the owner of the two-wheeler vehicle has to drag or use a towing vehicle for transporting the immobilized two-wheeler to the dealer for cancelling the immobilizing action of the immobilizer. Such conditions may be very disturbing for the real owner of the two-wheeler vehicle and may cause a lot of inconvenience to the owner of the two-wheeler vehicle.
The present disclosure envisages a user friendly immobilizer system that includes provisions for cancelling the immobilizing action of the immobilizer by only an authorized user and only after verification from the user. The user friendly immobilizer system is specifically for protection of two-wheelers that are parked in open environment. In one embodiment of the present disclosure, the user friendly immobilizer system does not require any key fob and accordingly eliminates the disadvantages associated with the use of key fob, such as circumstances arising due to loss of the key fob, thereby avoiding the inconvenience caused by the loss of the fob of the authorization system.
Referring to Figure 1, the immobilizer system 100 (also referred to as "the vehicle theft deterring system 100") includes an immobilizer unit 10, a detecting unit 50 and an authorization unit 70. The immobilizer system 100 of the present disclosure, utilizes the authorization unit 70 for cancelling the immobilizing action of the immobilizer. In accordance with an embodiment of the present disclosure the authorization unit 70 utilizes a micro-processor based control system for cancelling the immobilizing action of the immobilizer. In accordance with an embodiment of the present disclosure, the owner of the two-wheeler uses an authorization code for cancelling the immobilizing action of the immobilizer.

In accordance with an embodiment of the present disclosure the authorization code may be a TPIN or a code that is communicated to the real owner of the two-wheeler after verification of the real owner of the two-wheeler, wherein verification of the real owner is done by an interactive session. In accordance with an embodiment, the TPIN or code is communicated to a registered mobile number of the real owner. In accordance with another embodiment, the authorization unit 70 of the immobilizer system 100 enables communication of the owner of the two-wheeler with the dealer end, after verifying the owner of the two-wheeler. Such communication may be via internet, more specifically via a TCP IP protocol or a Campus Area Network (CAN). The user may use a personal digital assistant (PDA) or a network card protocol for interacting with the dealer end. In one embodiment, the user may use Bluetooth network for interacting with the immobilizer system 100. However, the present disclosure is not limited to any particular type of communication between the dealer end and the owner of the two-wheeler.
The dealer end in turn may provide temporary authorization to the user that may enable the user to temporarily cancel the immobilizing action of the immobilizer and drive the vehicle to the dealer, where the dealer may cancel the immobilizing action of the immobilizer and reset the immobilizer for future theft attempts. The immobilizer system ensures safety of the vehicle and prevents undesirable events such as vehicle lift, fuel theft, falling down of the vehicle, battery theft and other undesirable events. Further, the vehicle theft deterring system raises an alarm in case of any of the undesirable events such as vehicle lift, falling down of the vehicle, fuel theft, battery theft and others are detected.
In one embodiment, the immobilizer unit 10 immobilizes the ignition system 20 of the vehicle, particularly the two-wheeler, in case of an unauthorized and undesirable event occurring with the vehicle in the absence or without

permission of the owner of the two-wheelers is detected by the detecting unit 50. The undesirable event may be use of a wrong key to start the engine, cutting of the battery wire, shorting of ignition wire, fuel theft, falling down of the vehicle, and vehicle theft. In one embodiment, the immobilizer unit 10 is an ignition integrated immobilizer system for two-wheeler. More specifically, the immobilizer unit 10 is functionally coupled to the ignition coil and the spark plug of the ignition system 20 for selectively immobilizing the ignition system 20. The immobilizer unit 10 can selectively immobilize any type of ignition system irrespectively of whether the ignition system is an AC or DC type Capacitor Discharge Unit (CDI) or an induction discharge unit and a transistor control unit. In accordance with an embodiment of the present disclosure the undesirable event may be defined by the user of the vehicle theft deterring system 100, for example, the vehicle theft deterring system 100, may immobilize the vehicle in case a wrong key is inserted and keyed ON to start the engine.
The detecting unit 50 for detecting the undesirable event may use a variety of sensors for detecting the undesirable event occurring with the vehicle. For example, the detecting unit may use a vibration sensor which senses the vehicle lift (after a certain threshold) for detecting the vehicle lift, the detecting unit may use proximity sensors for detecting unauthorized access to the vehicle, the detecting unit may use fuel level sensors 50 for detecting fuel theft. The detecting unit may use RF communication inbuilt in crank position sensor for detecting pick up coil wire cut. The detecting unit may use battery sensors for detecting battery theft and wire cut.
In case any undesirable events reported, the immobilizer unit 10 immobilizes the ignition system 20 of the vehicle and also raises an alarm. The alarm may be a visual alarm or an audio alarm. If the main battery wire is cut, then system uses a secondary battery, which will be in-built in the unit. In accordance with

an embodiment of the present disclosure, the key fob of the two-wheeler may be remotely operated for immobilizing the ignition system of the two-wheeler. Further, the key fob of the two-wheeler may be communicably coupled to the visual indicators 60 and the key fob of the two-wheeler may be used for remotely actuating the visual indicators 60 and for tracking the two-wheeler vehicle. For example, the vehicle theft deterring system 100 uses RF (433 MHz) frequency and the Key fob has RF transmitter and a button for vehicle locator. When pressed, the vehicle's all 4 side indicators 60 will blink twice at a frequency of 1Hz, 2 Hz or at any frequency and also along with hooter operation. In accordance with another embodiment of the present disclosure, the key fob is a part of the authorization system that mobilizes the immobilized two-wheeler vehicle by cancelling the immobilizing action of the immobilizer.
The present disclosure envisages a user friendly immobilizer system that includes provisions for cancelling the immobilizing action of the immobilizer by only an authorized user in case the vehicle is immobilized by the immobilizer and even if the fob of the authorization system is lost. The authorization system is accessible only to the owner of the vehicle or anybody who is authorized by the owner of the two-wheeler vehicle.
The authorization unit 70 enables cancelling of the immobilizing action of the immobilizer, thereby facilitating driving of the vehicle by the owner of the vehicle and avoiding any inconvenience caused by the loss of the fob of the authorization system used for cancelling the immobilizing action of the immobilizer. In case of the user friendly immobilizer system of the present disclosure, the owner of the two-wheeler uses an authorization code for cancelling the immobilizing action of the immobilizer. In accordance with an embodiment of the present disclosure the authorization code may be a TPIN or a code that is communicated to the real owner of the two-wheeler after verification of the real owner of the two-wheeler. In accordance with an

embodiment, the TPIN or code is communicated to a registered mobile number of the real owner. In accordance with another embodiment, the authorization system 70 of the user friendly immobilizer system enables communication of the owner of the two-wheeler with the dealer end, after verifying the owner of the two-wheeler.
Such communication may be via internet, more specifically via a TCP IP protocol or a universal asynchronous receiver/ transmitter (UART). However, the present disclosure includes any of the of the communication means known in the art. The dealer end in turn may provide temporary authorization to the user that may enable the user to temporarily cancel the immobilizing action of the immobilizer and drive the vehicle to the dealer, where the dealer may cancel the immobilizing action of the immobilizer and reset the immobilizer for future theft attempts. The immobilizer system ensures safety of the vehicle and prevents undesirable events such as vehicle lift, fuel theft, falling down of the vehicle, battery theft and other undesirable events.
The "Immobilizer System" 100 operates through LF (Low Frequency - 125 KHz) coil on the ignition lock and a transponder on the key 30. In case of any of the undesirable events, the "Immobilizer System" 100 immobilizes the ignition system 20 of the two-wheeler, thereby preventing any undesirable and unauthorized events occurring with the two-wheeler. The "Immobilizer System" 100 further includes indicator means such as a hooter 40 and side light indicator means that get actuated in case of any of the undesirable events.
The two wheeler vehicle and the key fob is inbuilt with other user friendly features such as the "Energy Efficient Head Lamp Control System"
More specifically, the key FOB is a foldable key, wherein the mechanical key can be accessible by the press of a button in Key Fob and it has 3 push-buttons configured thereon, wherein the first push button operates the LED, the second

push-button is used for muting the hooter and the third push-button is for utilizing the "lead me to vehicle" facility that illuminates the ignition lock key hole, as required.
"Energy Efficient Head Lamp Control System" functions as disclosed below:
If the ignition key is sensed in ON position and the head lamp switch position transition is from OFF to ON, the control system interprets that the rider wants to intentionally switch on the head lamp and gives output signal to the driver circuit of the control system to switch ON the head lamp. Similarly, in the head lamp switch position changes from ON to OFF, the control system interprets that the rider wants to intentionally switch off the head lamp and gives output signal to the driver circuit of the control system to switch OFF the head lamp.
If the ignition key is sensed ON to OFF position, the control system gives an output signal to the driver circuit to switch ON the head lamp for a predetermined period of time (tl) and switch OFF the head lamp after that time period (tl) is over. If the ignition key is switched from OFF to ON position during that pre-determined time period (tl), the control system gives an output signal to the driver circuit to switch OFF the head lamp.
The unit is integrated in terms of hardware and software in one single unit for various functions of ignition control (CDI), engine immobilizer and other functions
Also the above features as of the 'vehicle locator' can also be implemented in a separate control units.
Figure 2 illustrates a key fob 202, a transponder 204, an antenna 206, an ignition lock body 208, an ignition ON/ OFF signal 210, a spark plug 212, a desktop or mobile 214, a power section 216, a microcontroller 218, an ignition unit 220, a communication unit 222, an ignition system 224 and an ignition coil 226. In

use, when an unauthorized/ authorized key, such as the key 202, is inserted inside an ignition lock body. The ignition ON/ OFF status circuit 210 conveys insertion of a key to the detecting unit 50. The detecting unit 50 in combination with the microcontroller sends a signal corresponding to an unauthorized/ authorized key to the transponder 204. The transponder 204 sends a corresponding signal to the detecting unit 50. The detecting unit 50 in combination with the micro controller checks the signal coming from the transponder 204. If the signal from the transponder 204 matches the signal sent by the detecting unit 50 and the microcontroller, then the key inserted is an authorized key. If the signal from the transponder 204 does not match the signal sent by the detecting unit 50 and the microcontroller, then the key inserted is an unauthorized key. In case of an unauthorized key insertion, the immobilizer unit 10 deactivate the ignition control unit of the two wheeler vehicle. The authorization unit 70 is functionally coupled to the immobilizer unit 10 for facilitating activation of the ignition control unit by authentication of the signal received from the detecting unit.
