DETAILED DESCRIPTION
[010] In conventional vehicles, a vehicle ignition system is accessed through a key. The key is used to turn on the vehicle ignition control and thereafter one or more vehicle components such as vehicle sensors, vehicle lamps are subsequently switched ON.
[011] In recent times, a conventional mechanical key for the vehicle is replaced with a keyless entry system. The key less entry system is conventionally embedded with one or more wireless communication means. These one or more wireless communications include a Bluetooth module, or a wireless Wi-Fi module, or a Low Frequency, High Frequency and Near field communication modules.
[012] These one or more wireless communication modules are generally embedded in a communication device such as mobile phones, tablets, smart key fobs or any other communication devices and are powered by batteries or electricity. These one or more wireless communication modules are communicatively paired with a vehicle through a vehicle control unit and is powered by an electric battery.
[013] Therefore, in such vehicle having keyless entry, the vehicle cannot be accessed for motion if the state of charge of the electric battery is below a particular threshold value or if the electric battery is dead.
[014] In order to overcome the above stated problem, an additional secondary battery is used to power the vehicle when the electric battery is dead or below a threshold voltage. However, accommodating an additional secondary battery requires multiple design changes in the vehicle layout which inadvertently increases the overall cost of the vehicle.
[015] Furthermore, if the primary as well as the secondary additional battery is drained out during vehicle operation, the vehicle is abruptly stopped and there are no alternatives, but to take the vehicle to a nearby service station for changing of the batteries.

[039] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[040] Figure 1 illustrates a block diagram of an ignition control and vehicle unlocking system (100) for a vehicle (102), in accordance with an embodiment of the present subject matter. A vehicle ignition control and vehicle unlocking system (100) is disposed inside a vehicle (102). The vehicle ignition control and vehicle unlocking system (100) is communicatively connected wirelessly to a connecting device (104). In one embodiment, the connecting device (104) is an electronic key of the vehicle (102). The electronic key being a smartphone, a tablet, a smart device or any other electronic communication device. The vehicle ignition control and vehicle unlocking system (100) comprising a display panel (106) of the vehicle (102). The display panel (106) further comprising a communication controller (106a) and a pairing unit (106b). The pairing unit (106b) electronically pairs with a pairing unit (104a) of the connecting device (104). In one embodiment, the pairing unit (106b, 104a) being a Bluetooth receiver, or a WIFI receiver, or a Low Frequency and High Frequency receiver and Near field communication receiver. The communication controller (106a) is enabled to process the pairing of the vehicle (102) with the connecting device (104) and thereby initiate authentication process of a user of the vehicle (102).
[041] The vehicle ignition control and vehicle unlocking system (100) further comprising a vehicle control unit (112) and an engine control unit (108). The display panel (106) communicatively interacts with the vehicle control unit (112) and the engine control unit (108) through CAN communication. The vehicle control unit (112) electronically controls an ignition relay coil (110). The vehicle control unit (112) electronically controls opening and closing of the ignition relay coil (110) for vehicle starting purposes. The vehicle control unit (110) is further configured to electronically control one or more vehicle components. The one or more vehicle components includes an ignition and engine control unit (114), a seat or a fuel cap or a charger port control unit (116) and an engine steering lock (118). The one or more vehicle components, the vehicle control unit (112), the display panel (106) and the engine control unit (108) is charged by a power source of the vehicle (102). The power source is a battery in one embodiment.
[042] In one embodiment, the connecting device (104) is an electronic communicating device including a processor (104c) and a secondary authentication unit (104b) for enabling authentication of a user of the vehicle (102). The authentication process is a primary authentication and a secondary authentication process in one embodiment.
[043] In one embodiment, the ignition relay coil (110) generally lies in an open state and is enabled to be closed when an electronic key fob is paired with the vehicle and thereby the vehicle is turned ON.
[044] Figure 2a illustrates a fail-safe method (200) for ignition control and vehicle unlocking for the vehicle (102), in accordance with an embodiment of the present subject matter. Figure 2b illustrates the fail-safe method (200) for ignition control and vehicle unlocking for the vehicle (102), in accordance with an embodiment of the present subject matter. Figure 2c, 2d illustrates the fail-safe method (200) for ignition control and vehicle unlocking for the vehicle (102) with respect to one or more vehicle predetermined parameters, in accordance with an embodiment of the present subject matter. For brevity figures 2a, 2b, 2c and 2d will be discussed together. A fail-safe method (200) for ignition control and vehicle unlocking by the vehicle ignition control and vehicle unlocking system (100) comprising the following steps. In step (202), the vehicle control unit (112) checks a battery voltage value and compares if the battery voltage value is less than a threshold battery voltage value. In one embodiment, the threshold battery voltage value is not more than 8 volts. If the battery voltage value is less than the threshold battery voltage value, then in step (204) the vehicle is started by the fail-safe method by shutting down all electronic key fob connection and thereby enabling manual start of the vehicle (102) by a kick start mechanism from the user as shown in step (207).
[045] The ignition relay coil (110), originally lying, in an open state, is enabled to be closed the vehicle control unit (110) as shown in step (206) for enabling manual kick start operation to start the vehicle (102). Further, after the vehicle (102) is started using a kick start mechanism, the vehicle control unit (112) checks whether the vehicle is started or not as shown in step (208). The starting of the vehicle (102) enables the battery to consequently charge slowly and thereby provide power supply to the vehicle control unit (112) and the one or more vehicle components.
[046] However, by providing a mechanism to kick start the vehicle during low battery voltage value, another problem of theft of the vehicle (102) is encountered. The kick start can be provided by anyone and the same need not be provided by the user of the vehicle (102), and hence makes the vehicle (102) vulnerable to a potential threat of theft and damage. Hence, an authentication mechanism to verify the user of the vehicle (102) after starting the ignition of the vehicle (102) with a kick start mechanism, is required for safe and theft proof operation of the vehicle (102).
[047] Once the vehicle control unit (112) determines that the vehicle (102) is started by kick starting as shown in step (208), the vehicle control unit (112) draws limited power supply from the battery and starts scanning the signals of the pairing units (106b, 104a) of the vehicle (102) and the connecting device (104) respectively, for authentication of the registered user of the vehicle (102) as shown in step (209). Thereafter, as shown in step (210), the vehicle control unit (112) determines if a signal strength of the connecting device (104) is greater than or equal to a threshold signal strength (XX dB). In one embodiment, the XX dB is not less than 50 dB. If the above stated condition is satisfied, then the vehicle control unit (112) asks for a primary key of the pairing unit (104a) of the connecting device (104) as shown in step (211). If the primary key provided by the connecting device (104) of the user is present and verified by the vehicle control unit (112), then the user is recognized as the registered user and a seamless entry to other vehicle control and components is provided to the user as shown in step (212).
[048] Further, if the primary key is not present or verified by the vehicle control unit (112), then the vehicle control unit (112) waits for a prescribed time period as shown in step (213). The prescribed time period not exceeding 120 seconds in one embodiment. After the prescribed time period is over, the vehicle control unit (112) shuts off the engine ignition by opening the ignition relay coil (110) and thereby cutting off the power supply from the battery as shown in step (214). Thereafter, the vehicle control unit (112) checks for the battery voltage value again as shown in step (216). If the battery voltage value is greater than or equal to the threshold battery voltage value, then the vehicle control unit (112) stops the fail-safe method and the vehicle (102) is completely shut down. The vehicle (102) is enabled to be restarted by electronically pairing the connecting device (104) with the vehicle (102) and thereby restarting it.
[049] In another scenario, if the vehicle control unit (112) checks the signal strength and determines that the signal strength is less than the threshold signal strength (XX dB), as shown in step (210), then the vehicle control unit (112) comes to a conclusion that the registered user is away from the vehicle (102). Thereafter, the vehicle control unit (112) checks and compares a speed of the vehicle (102) with a threshold vehicle speed (YY kmph) to determine whether the vehicle (102) is forcibly in motion during theft of the vehicle (102) as shown in step (215). If the vehicle control unit (112) determines that the vehicle speed is less than the threshold vehicle speed, then the vehicle control unit (112) waits for a prescribed time as shown in step (213) to determine the pairing of the vehicle (102) with the connecting device (104). After the prescribed time is over, the vehicle control unit (112) turns off the engine ignition as shown in step (214) and stops all the vehicle functions completely. However, if the vehicle control unit (112) determines that the vehicle speed (215) is greater than the threshold vehicle speed, then the vehicle control unit (112) immediately turns off the engine ignition at step (214) and shuts down the vehicle (102) if the battery voltage is greater than the threshold battery voltage, and stops the fail-safe method (200), as shown in step (217). The vehicle control unit (112) if determines the battery voltage to be less than the threshold battery voltage then the vehicle control unit (112) stops working and initiates the kick start mechanism to start the ignition of the vehicle (102) as shown in step (207).
[050] Figure 3 illustrates a method (300) of authentication for confirmation of a verified user, in accordance with an embodiment of the present subject matter. In the method (200) of ignition control and vehicle unlocking by the vehicle ignition control and vehicle unlocking system (100) of the vehicle (102), if the vehicle control unit (112) checks and determines that the battery voltage is greater than the threshold battery voltage value as shown in step (202), then the vehicle (102) is started with preapproved authentication of the registered user through pairing of the electronic connecting device (104) with the vehicle (102). The method of preapproved authentication (300) of the registered user comprises of the following steps. The communication controller (106a) of the display panel (106) of the vehicle (102) detects and scans pairing identifications of the pairing unit (106b, 104a) of the vehicle (102) and the connecting device (104) as shown in step (301). If the pairing identification matches, then the communication controller (106a) scans and checks for signal strength of the pairing unit (104a) of the connecting device (104) and further electronically sends the details to the vehicle control unit (112) as shown in step (302).
[051] The vehicle control unit (112) then compares the signal strength of the pairing unit (104a) with a predetermined signal strength as shown in step (303). If the signal strength of the pairing unit (104) is greater than the predetermined signal strength, then the vehicle control unit (112) initiates a secondary authentication procedure by electronically mapping with the secondary authenticator (104b) of the connecting device (104) as shown instep (304). If the secondary authentication is successful, then the vehicle control unit (112) identifies the user as the registered user and disengages lock pad, steering lock and allows the vehicle (102) to be maneuvered and functioned by the registered user. If the signal strength of the pairing unit (104) is less than the predetermined signal strength, then the vehicle control unit (112) locks the lock pad of the vehicle (102) and shuts down the vehicle (102) by turning off the engine and engine steering lock as shown in step (306, 307). Therefore, the vehicle (102) is configured to be accessed by a registered user only and thereby prevents theft of the vehicle (102).
[052] Figure 4 illustrates a method (400) of authentication for confirmation of a verified user in another embodiment, in accordance with an embodiment of the present subject matter. The authentication of the registered user is controlled wirelessly by the vehicle control unit (112). In another embodiment, the authentication process of the registered user is done by a two-step verification process. The method of two-step authentication (400) of the registered user comprises of the following steps. The communication controller (106a) of the display panel (106) of the vehicle (102) detects and scans pairing identifications of the pairing unit (106b, 104a) of the vehicle (102) and the connecting device (104) as shown in step (401). If the pairing identification matches, then the communication controller (106a) scans and checks for signal strength of the pairing unit (104a) of the connecting device (104) and further electronically sends the details to the vehicle control unit (112) as shown in step (402).
[053] Thereafter the vehicle control unit (112) initiates and check a first step user verification process by checking matching of a primary key of the vehicle (102) with the connecting device (104) as shown in step (403). Once the first step user verification process is completed, the vehicle control unit (112) enables a second step user verification process through problem solving algorithms as shown in step (404). The problem-solving algorithms being simple mathematical problems which is configured to be provided to the registered user, and the registered user being required to solve the problem and provide a solution for the same on the connecting device (104). The vehicle control unit (112) receives the solution from the connecting device (104) wirelessly and further compares the solution with a predetermined value as shown in step (405). If the solution matches with the predetermined value, then the vehicle control unit (112) concludes that the user is the registered user and enables engine and engine steering control functions for smooth functioning of the vehicle (102) by the registered user.
[054] The claimed steps as discussed herein are not routine, conventional, or well understood in the art, as the claimed steps enable the following solutions to the existing problems in conventional technologies.

[055] While the present invention has been shown and described with reference to the foregoing preferred embodiments, it will be apparent to those skilled in the art that changes in form, connection, and detail may be made therein without departing from the spirit and scope of the invention.
