PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION
[0001] The present disclosure relates to a security system for a vehicle and, more particularly, to a security system that utilizes dual mode controller connected to the one or more sensors disposed at a vehicle to provide security to the vehicle in moving, stationary and parked condition.
BACKGROUND OF THE INVENTION
[0002] Theft of articles from moving and parked motor vehicles is increasing. Warning systems have been introduced to cope with theft attempts by issuing a warning when a vehicle side door, trunk lid or the like is opened using an abnormal way. High security door locks are used sometimes to prevent such theft, but it does not alert the owner and driver when the vehicle is left unattended and most of the time user got to know about the theft once it is done. However, often there is a lag in detection that there has even been a theft because the drivers may not realize it until they reach the point of delivery, after making multiple stops along the route. As a result, police may be reluctant to file a report if the driver is unsure of where the theft occurred.
[0003] Further, many cases of cargo theft are exposed where the goods are stolen from moving vehicles on secluded roads. In such cases, due to the size of the cargo vehicles, the driver often remains unaware of rear side of the vehicle. Such theft cases can be prevented to an extent by installing high end surround view cameras. But use of such high end camera system does not completely solves the problem, because this system alerts the driver only during theft situation and does not warn the intruder while they are attempting theft.

[0004] Various conventional vehicle anti-theft detection and alerting systems and methods thereof are proposed but each of the conventional system is specific to a theft type and does not provide a complete solution to cover which caters all major theft types such as theft when the vehicle is in parked condition, theft when the vehicle is moving, and theft when the vehicle is stationary. Further, use of different solutions for each of the theft type involves extra cost to the owner of the vehicle.
[0005] Therefore, there is a need for a robust, complete and cost effective theft alert system for a vehicle to overcome above mentioned problems.

[0029] Referring now to the drawings, and more particularly to FIGS. 1-2, there are shown preferred embodiments.
[0030] FIG. 1 illustrates a schematic representation of a security system for a vehicle, according to embodiments as disclosed herein. The security system includes one or more sensors (1) disposed at the vehicle and a dual mode controller (2) connected to the one or more sensors (1).

[0031] The one or more sensors (1) is embedded in a vehicle vision system, a reverse parking assist system (RPAS), and/or an object detection system. In a preferred embodiment of the invention, the one or more sensors (1) are installed at a rear portion of the vehicle as per regulatory guidelines such that the one or more sensors (1) is used for getting the dual functionality such as providing rear parking assistance to the user while the vehicle is moving in a reverse direction, and detecting an intruder around the vehicle. The one or more sensors (1) described herein are essentially proximity sensors which measures distance of the object in detection zone from them. Once the sensors are activated, they keep on tracing object in their respective detection zone. In regular RPAS, these sensors gets activated once gear position is set to reverse gear. In the present system, the sensors (1) remain activated all the time irrespective of gear position & vehicle condition i.e. moving, stationary & parked.
[0032] In an embodiment, the system can include multiple exterior facing sensors, such as a forward facing sensor at the front of the vehicle, a sideward/rearward facing sensor at respective sides of the vehicle, etc. Each of the one or more sensors (1) has a respective field of view exterior of the vehicle and is operable to capture image data and proximity data.
[0033] The dual mode controller (2) is connected to the one or more sensors (1) and is operable in a reverse parking assistance mode and a theft detection mode. In an embodiment, the dual mode controller (2) is embedded in a vehicle vision system, a RPAS, and/or an object detection system. In a preferred embodiment of the invention, the dual mode controller (2) is installed in the RPAS such that the dual mode controller (2) is operable in a reverse parking assistance mode and a theft detection mode. When operating in the theft

detection mode, the dual mode controller (2) detect an intruder at or near the vehicle using the one or more sensors (1). When operating in the reverse parking assistance mode, the dual mode controller (2) alert a driver of obstacle while moving the vehicle in a reverse direction using the one or more sensors (1). The configuration of the dual mode controller (2) can be automatically done based on a state of the ignition of vehicle. The dual mode controller (2) would function in dual mode. The dual mode controller (2) behaves as regular RPAS in reverse gear position when ignition is on and works as theft alert system for goods in any gear position other than reverse gear and also in ignition off condition.
[0034] The dual mode controller (2) is connected to a gear system (3), a cabin buzzer (4), a siren (5), a Telematics control unit (TCU) (6), a push button (7), and a Vehicle electronic control unit (VECU) (8) using electric connection (9) and/or a Controller Area Network (CAN bus) communication (10).
[0035] The gear system (3) allows the vehicle to be driven with the minimum strain on the engine. The gear system (3) provides information of a gear position such as reverse or other than reverse gear to the VECU (8) through the electric connection (9). Further, the VECU (8) communicates this input to dual-mode controller (2) through the CAN Communication (10).
[0036] The cabin buzzer (4) (also referred as beeper) is installed inside a cabin of the vehicle to provide an audio signal to the driver inside the vehicle. The cabin buzzer (4) can be electromechanical, or piezoelectric.
[0037] The siren (5) (also referred as hooter) is installed at a rear side of the vehicle to thwart off the intruder. In response to receiving the dual mode controller (2), the siren (5) alerts the intruder while attempting the theft and do

not let the theft happen. Unlike the conventional mechanisms where there is no mechanism to warn the intruder while attempting the theft, this type of proposed alerting mechanism can effectively warn the intruder while attempting the theft. Further, the push button (7) is provided on dashboard of the vehicle, which can be used by the driver to suppress the warning in theft alert mode in moving condition especially in bumper to bumper or city traffic. This feature is provided to avoid possible false warning in case of city traffic.
[0038] The TCU (6) is installed inside a cabin of the vehicle. In response to receiving the dual mode controller (2), the TCU (6) triggers a pre-defined message to driver and fleet owner to alert them of potential theft attempt. This feature is provided as vehicle is mostly unattended in parked condition and user can’t be informed of potential theft attempt by audio warning only. In an embodiment, the predefined message can include a location information of the vehicle. This is used for easy tracking of the vehicle by the owner or the driver. Unlike the conventional mechanism, this type of proposed alerting mechanism to alert the driver and owner of the vehicle especially when the vehicle is in parked condition can effectively prevent the theft in unattended vehicle. Further, the TCU (6) includes a global positioning system (GPS) unit, which keeps track of the latitude and longitude values of the vehicle and tracks the location of the vehicle, an external interface for mobile communication to share the predefined message with the owner, driver or any other caretaker of the vehicle.
[0039] The complete working of the dual mode controller (2) can be divided in two parts, i.e., switched OFF condition of the vehicle ignition and switched ON state of vehicle ignition. Based on status of the ignition state, the dual mode controller (2) automatically operate in appropriate mode.

[0040] The dual mode controller (2) detects whether an ignition of the vehicle is in an on-condition or an off-condition. The dual mode controller (2) operate in the theft detection mode to detect an intruder at or near the vehicle using the one or more sensors (1) when it is detected that the ignition of the vehicle is in the off-condition. And, the dual mode controller (2) operate in both the theft detection mode to detect an intruder at or near the vehicle using the one or more sensors (1) and the reverse parking assistance mode to alert a driver of obstacle while moving the vehicle in a reverse direction using the one or more sensors (1) when it is detected that the ignition of the vehicle is in the on-condition.
[0041] When the dual mode controller (2) operates in both the theft detection mode and the reverse parking assistance mode, the dual mode controller (2) is configured to detect whether a reverse gear of a gear system (3) is engaged. Here the gear system (3) provides information of the gear position either in the reverse or in forward position to the VECU (8) through electric connection (9). Further, the VECU (8) communicates this input to dual-mode controller (2) through the CAN Communication (10). The dual mode controller (2) operates in the theft detection mode in response to detecting that the reverse gear of the gear system (3) is not engaged, and the dual mode controller (2) operates in the reverse parking assistance mode in response to detecting that the reverse gear of the gear system (3) is engaged.
[0042] When the dual mode controller (2) is operating in the theft detection mode, the dual mode controller (2) activates the sensor (1) having the field of view and continuously monitors a presence of an object in the field of view of the sensor (1). If the object is present within a predefined distance from the vehicle for a period of time then the dual mode controller (2) consider it as a

situation of presence of the intruder at or near the vehicle and sends a signal to alert the driver of the vehicle about the intruder. In this scenario, the dual mode controller (2) adapts a unique alerting mechanism based on a statue of the ignition state of the vehicle. Before providing the alert in theft alert mode, the dual mode controller (2) detect whether the ignition of the vehicle is in the on-condition or the off-condition.
[0043] When it is detected that that the ignition of the vehicle is in the off-condition, the dual mode controller (2) send a signal to the cabin buzzer (4) to alert the driver of the vehicle about the intruder,send a signal to the siren (5) to warn the intruder while attempting theft, and send a signal to the TCU (6) to trigger pre-defined message to the driver or an owner/caretaker of the vehicle to alert about the intruder. This type of alerting mechanism ensures that the driver and owner are properly alerted about the theft especially when the vehicle is in parking condition and the driver is away from the vehicle location. Further, when it is detected that the ignition of the vehicle is in the on-condition, send a signal to the cabin buzzer (4) to alert the driver of the vehicle about the intruder and send a signal to the siren (5) to warn the intruder while attempting theft.
[0044] Alternatively, when the dual mode controller (2) is operating in the reverse parking assistance mode, the dual mode controller (2) activates the sensor (1) having the field of view and detects whether the obstacle in the field of view of the sensor (1) is within a predefined distance from the vehicle. If the obstacle is detected within the predefined distance from the vehicle then the dual mode controller (2) sends a signal to the cabin buzzer (4) to alert the driver of the vehicle.

[0045] FIG. 2 illustrates a flow chart illustrating a method for providing a security to the vehicle, according to embodiments as disclosed herein. At step 11, the method includes detecting whether an ignition of the vehicle is in an on-condition or an off-condition.
[0046] In response to detecting that the ignition state of the vehicle is in the on-condition, at step 12, the method includes operating the dual mode controller (2) in both the theft detection mode to detect an intruder at or near the vehicle using the sensor (1) and the reverse parking assistance mode to alert a driver of obstacle while moving the vehicle in a reverse direction using the sensor (1). Further, in response to detecting that the ignition of the vehicle is in the off-condition, the method flow to step 18 and includes operating the dual mode controller (2) in the theft detection mode to detect an intruder at or near the vehicle using the sensor (1).
[0047] At step 13, the method includes detecting whether a reverse gear of the gear system (3) is engaged when the dual mode controller (2) operates in both the theft detection mode and the reverse parking assistance mode. Based on the input from the gear system (3), the dual mode controller (2) detects the gear position of the vehicle during ignition on condition. In response to detecting that the reverse gear of the gear system (3) is engaged, at step 14, the method includes operating the dual mode controller (2) in the reverse parking assistance mode. In response to detecting that the reverse gear of the gear system (3) is not engaged, the method flow to step 18 and includes operating the dual mode controller (2) in the theft detection mode; and
[0048] When the dual mode controller (2) operates in the reverse parking assistance mode, the ignition is on and the reverse gear is engaged, at step 15,

the method includes detecting obstacle continuously using the sensor (1). The sensor (1) is activated and the obstacle in a field of view of the sensor (1) is continuously monitored. At step 16, the method includes detecting whether the obstacle in the field of view of the sensor (1) is within a predefined distance from the vehicle. Further, in response to detecting the obstacle within the predefined distance from the vehicle, at step 17, the method includes sending a signal to the cabin buzzer (4) to alert the driver of the vehicle and method continues determining the gear position.
[0049] Alternatively, at step 18, the method includes operating the dual mode controller (2) in the theft detection mode.. In this scenario, at step 19, the method includes monitoring objects in a field of view of the sensor (1). The dual mode controller (2) activates the sensor (1) and continue monitoring the movements of objects available in the field of view exterior to the vehicle. At step 20, the method includes determining whether the object is present within a predefined distance from the vehicle for a period of time. In response to determining that the object is not present within the predefined distance from the vehicle for the predefined period of time, at step 21, the method includes avoid sending any alert signal.
[0050] Further, in response to determining that the object is present within the predefined distance from the vehicle for pre-defined duration, at step 22, the method includes detecting whether the alert signal is cut off by pressing the push button (7).
[0051] When the push button (7) is pressed then the method includes avoid sending any alert signal as indicated at step 21. Otherwise, the method flows to step 23 and includes alerting the driver of the vehicle about the intruder by using

a unique alerting mechanism based on status of the ignition of the vehicle as described at steps 23-26 based on the ignition status in the on-condition or the off-condition.
[0052] At step 23, the method includes detecting whether the ignition of the vehicle is still in the on-condition or the off-condition. It is important to determining the status of the ignition as the type of alert to be given by the system differs based on the status. When the ignition is in the ON condition the driver is likely to be present inside the vehicle and when the ignition is in the off condition the driver may have parked the vehicle and not available near the vehicle. Hence it is important to assess the ignition status before providing the alert.
[0053] In response to detecting that the ignition of the vehicle is in the on-condition, the method flow at step 24-25 and includes sending a signal to the cabin buzzer (4) to alert the driver of the vehicle about the intruder, sending a signal to the siren (5) to warn the intruder attempting theft, As when the ignition engine is in the on condition, the driver is likely to be present inside the vehicle and alerting the driver using the cabin buzzer (4) is the most appropriate decision in this scenario.
[0054] In response to detecting that the ignition of the vehicle is in the off-condition, the method flow at step 24-26 and includes sending a signal to the cabin buzzer (4) to alert the driver of the vehicle about the intruder, sending a signal to the siren (5) to alert the intruder while attempting theft, and sending a signal to a the TCU (6) to trigger one or more pre-defined messages to at least one of the driver and an owner of the vehicle to alert about the intruder. In this scenario, as the ignition engine is in the off condition, it is possible that the driver

might have parked the vehicle and not available near the vehicle. In such scenario, sending the signal only to the cabin buzzer (4) to alert the driver of the vehicle about the intruder is not an appropriate decision as it is possible that the drive is not present inside the cabin of the vehicle. Hence to ensure that that alert is properly delivered, the alert signal is shared with the cabin buzzer (4), the siren (5) and the TCU (6). In an embodiment, the message can also include location information of the vehicle. This is used by the driver or owner for easy tracking of the vehicle.
[0055] Unlike the conventional mechanism, this type of unique alerting mechanism can be used to provide effective alert signal to the driver and owner of the vehicle in moving, stationary and parked condition. Further, the proposed security system prevents theft and robbery involving goods carried by the vehicle at any state thus providing a complete solution to cover which caters all major theft types such as theft when the vehicle is in parked condition, theft when the vehicle is moving, and theft when the vehicle is stationary.
[0056] The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
