Theft prevention system 100, according to embodiments of the present invention. Theft prevention system 100 is operatively installed in a respective vehicle 110, wherein theft prevention system100 includes at least one vehicle built-in means (160) for validating the driver’s legitimacy.

[0058] [Para 35] The built-in driver validation unit 160 may include, with no limitations: a camera, a fingerprint recognition device, or any other built-in means capable of validating a driver. The built-in driver validation unit may also include a pre-selected sequence of multiple built-in operating buttons (122, see for example Fig. 2) situated inside the vehicle inner space, wherein the pre-selected operating buttons are individually identifiable by the vehicle computer (ECU) over the common vehicle communication bus. The built-in driver validation unit is situated inside the vehicle inner space and does not include any outside display for drivers to activate or to be used with any other external means.

[0059] [Para 36] Upon detecting unauthorized usage of the vehicle, the system disables activations of the vehicle motor via the vehicle ,data bus.

[0060] [Para 37] Optionally, built-in driver validation unit 160 includes an ordered set of pre-selected built-in operating buttons 122 that are situated inside the vehicle inner space of the vehicle, and available to the driver. Here too, upon detecting an unauthorized usage of the vehicle, the system disables activations of the vehicle motor via the vehicle data bus.

[0061] [Para 38] Operating buttons 122 may be located, for example, on the steering wheel 120, the dashboard, the driver’s door, etc. It should be appreciated that operating buttons 122 are individually identifiable by the vehicle 110 computer, that is referred to, herein, as ECU 130. Theftprevention system 100 further includes a telematics unit 140, that is passively connected to the common vehicle communication bus 115.

[0062] [Para 39] It should be appreciated that the system of the present invention neither intervenes nor interferes with the vehicle communication over the data busl l 5. However, the passive data buscontactless listener captures the code of the built-in driver validation unit by way similar to reverse engineering and listens continuously, however passively, to all of the traffic of communication data messages flowing over CAN BUS 115 and when an incorrect code is entered Theft prevention system 100 immobilizes the engine.

[0063] [Para 40] The innovative telematics unit 140 includes a passive data buscontactless-listener 142, a built-in driver validation unit 144, and an immobilizer control unit 146. Theft prevention system 100 further includes a specific immobilizer terminal 150, which is operatively connected to immobilizer control unit 146. Specific immobilizer terminal 150 is configured to disable the host vehicle engine, typically by software means, upon detecting a theft attempt. Optionally, upon detecting a theft attempt, to prevent ignition of the host vehicle engine, theft prevention system 100 disables the vehicle starter. Optionally, to prevent ignition of the host vehicle engine, the built-in immobilizer of host vehicle is disabled. Optionally, to prevent ignition of the host vehicle engine, the vehicle gear shifting mechanism is disabled.

[0064] [Para 41] Reference is also made to Figs. 2a and 2b, which depict a non-limiting example of setting and usage of a pre-selected subset ofmultiple built-in operating buttons 122, to thereby set a secret button combination for locking / unlocking the vehicle, according to variations of the present invention.

[0065] [Para 42] It should be noted that all inner space operating buttons that are accessible to the driver, are referred to as valid operating buttons 122 for setting a secret button combination.

[0066] [Para 43] Theft prevention system 100 includes an optional preselected subset of operating buttons 122, (which may include those on the vehicle steering wheel (120)), and / or all other accessible vehicle inner space operational buttons), and the vehicle engine control unit ECU 130 that can communicate with the preselected subset of operating buttons 122. When the driver presses a button, a specific command is sent to ECU 130, and the ECU 130 transmits the data via data busl 15. Telematics unit 140 is configured to continuously listen to all communications within the vehicle’s data busl 15, via a passive contactless-listener 142. Button-sequence-validation unit 144 of telematics unit 140 parses sequence of pressed buttons in order to validate the sequence of the just entered (pressed) button sequence, with the secret sequence of buttons vehicle code that is stored in the ECU 130 memory. It should be appreciated that the code sequence can be remotely updated by the provider of the theft prevention system 100 (or any other authorized body), including re-setting the buttons sequence thereof.

[0067] [Para 44] It should be further appreciated that ECU 130 controls a tCUT relay 152 based on the state of the immobilizer control unit 146. Relay152 is responsible for controlling vehicle immobilization, while a specific immobilizer terminal 150 manages the vehicle start / stop functionality.

[0068] [Para 45] As shown in Figs. 2a and 2ba non-limiting example 200 of buttons setting and usage of the multiple operating buttons 122, for setting a secret button combination for locking / unlocking the vehicle, is shown. Fig. 2b is an enlarged view of example region 202. This specific non-limiting example region 202 contains multiple operating buttons 122a-f from which region, is sub set of selected buttons are used to set up a confidential sequential group of 4 selected buttons: button 122a is selected to be the 1stof the sequence of 4 buttons, button 122b is selected to be the 2nd, button 122c is selected to be the 3rd, and button 122d is selected to be the 4thone. It should be noted that in this specific non-limiting example, buttons 122e-f do not participate in the secret sequence, as also applied to all other buttons available to the driver.

[0069] [Para 46] Since the four preselected buttons are integral buttons of the vehicle, a thief breaking into the vehicle has no idea which of the multiple buttons have been selected and in which order and there is no outside display for drivers to activate or to be used with any other external means. He cannot know if and how the vehicle is protected. Furthermore, he doesn’t know how to disconnect or bypass the hidden immobilizer, as there are no wires to cut.

[0070] [Para 47] In variations of the present invention, the random button activation sequence is configured via an OTA (Over-the-Air) commandor via BT.

[0071] [Para 48] The following is a non-limiting example of an arming process of the vehicle:

[0072] ■ The ignition is turned OFF.

[0073] ■ After X seconds, the immobilizer arms.

[0074] ■ The tCUT relay is activated, to thereby bring theft-prevention system 100 to an armed state.

[0075] ■ Once the tCUT relay is armed, the vehicle is immobilized.

[0076] [Para 49] Reference is also made to Fig. 3 that schematically illustrates a flowchart diagram of an example usage of theft prevention method 300, using theft prevention system 100, according to embodiments of the present invention. Method 300 includes the following steps:

[0077] ■ The driver enters the vehicle (step 301 ).

[0078] ■ The driver enters a valid button sequence (step 310), the tCUT relay is disarmed, and the vehicle is ready to operate.

[0079] ■ The immobilizer enters the disarmed state (step 320), deactivating the tCUT relay (step 330).

[0080] ■ Upon entering an invalid button sequence, the system remains immobilized.

[0081] [Para 50] Optionally, additional means for identifying and / or validating the driver’s identity may be used to identify and / or validate the driver's identity, in particular, original manufacturer built-in identification means. For example, with no limitations:

[0082] ■ usage of a driver's fingerprint.

[0083] ■ usage of a built-in vehicle camera capable of identifying the driver.■ An identification validation application.

[0084] Such devices are then utilized to allow ignition of the engine, without interfering with any other data traffic on the vehicle’s data bus.

[0085] [Para 51] Reference is also made to Fig. 4 that schematically illustrates a flowchart diagram of an example usage of a theft prevention method 400, using theft prevention system 100, according to embodiments of the present invention. Method 400 includes the following steps:

[0086] [Para 52] Vehicle theft prevention process (example scenario)-.

[0087] A thief breaks into the vehicle (step 401).

[0088] ■ The thief attempts to start or drive the vehicle remains armed (step 410).

[0089] ■ Since the vehicle does not enter into a drive mode, and thereby, the vehicle remains in the armed state, and does not enter drive mode (step 420).

[0090] ■ The system activates an alert (step 430).

[0091] ■ the thief is unable to operate the vehicle.

[0092] [Para 53] In another example scenario, the vehicle includes the built-in means to identify the driver, wherein built-in means for identifying the driver 160, as schematically illustrated in Fig.l . Upon a driver entering the vehicle and activating the built-in means to identify the driver, the built in means for identifying the driver validates the drivers identity:

[0093] ■ upon a positive identification, the built-in means 160 for identifying the driver sends a safe-to-ignite massage, which safe-to-ignite massage is detected by vehicle theft prevention system 100 viapassive contactless-listener 142, allowing the vehicle to move to a disarmed state, facilitating safe ignition of the vehicle motor; and ■ while not detecting safe-to-ignite massage, the vehicle remains in an armed state.

[0094] [Para 54] It should be appreciated that the built-in means for identifying the driver may include a camera, a fingerprint recognition device, or any other built-in means capable of identifying a driver. It should be further appreciated that, being built-in devices, they can be detectable by passive contactless-listener 142.

[0095] [Para 55] The invention being thus described in terms of several embodiments and examples, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art.
