[0027] In this specification, the present invention is more comprehensively described with reference to the accompanying drawings that illustrate schematic embodiments of the present invention. However, the present invention can be implemented in different forms and should not be construed as limited to the embodiments given herein. The given embodiments are intended to make the disclosure herein complete and to more comprehensively convey the scope of protection of the present invention to those skilled in the art.

[0028] It should be noted that the terms "first", "second", "primary", "secondary", etc. in this article are used to distinguish similar objects and do not necessarily describe the order of the objects in terms of time, space, size, etc. In addition, unless otherwise specifically specified, the terms "include", "comprise" and similar expressions in this article are intended to mean non-exclusive inclusion. And the term "vehicle" or other similar terms in this article include general motor vehicles, such as passenger cars (including sport utility vehicles, buses, trucks, etc.), various commercial vehicles, etc., and include hybrid electric vehicles, electric vehicles, plug-in hybrid electric vehicles, etc. A hybrid electric vehicle is a vehicle with two or more power sources, such as a gasoline-powered and an electric vehicle.

[0029] The purpose of vehicle anti-theft mentioned in this application is to prevent the vehicle from being illegally entered, started or driven away without a valid key. This application proposes a three-step authentication method for vehicle anti-theft, that is, first, authenticate the validity of the key (for example, a smart key) to prevent unauthorized personnel or invalid keys from illegally entering or activating vehicle functions; second, perform key domain authentication between the body control module and the gateway. If the authentication is passed, the basic functions of the vehicle can be activated; third, perform driveline authentication between the gateway and the powertrain control module. If the authentication is passed, the vehicle driving function is activated, that is, the vehicle control unit will allow the vehicle to shift to "Drive (D gear)" or "Reverse (R gear)". By performing the above three authentications in sequence, it is possible to achieve step-by-step activation of vehicle functions while improving the security and reliability of the anti-theft system.

[0030] Now refer to Figure 1 , Figure 1 FIG. 1 is a schematic block diagram of a system 100 for vehicle anti-theft authentication according to an embodiment of the present invention.

[0031] In Figure 1 embodiment, the system 100 includes a body control module 110, a gateway 120, and a motor control module 130. In Figure 1 The vehicle anti-theft authentication system shown is an authentication system applied to an electric vehicle, so it is implemented by the motor control module 130. If it is applied to a fuel vehicle, the engine control module replaces the motor control module 130. The following description will take the case of an electric vehicle as an example. In some embodiments according to the present application, the system 100 may further include one or more sensors for detecting the presence of the driver.

[0032] Exemplarily, when the user inserts the key into the ignition device or brings the smart key into the vehicle, the key can send the electronic code (that is, key information) stored therein to the body control module 110. The body control module 110 can determine whether the received electronic code matches the information preset in the body control module 110. If the body control module 110 determines that the electronic code matches the preset information, it means that the key is valid and enters the following key domain authentication stage. If the body control module 110 determines that the received electronic code does not match the preset information, it means that the key is invalid, and the entire authentication process fails and ends. In the case where the authentication process fails, the system 100 (for example, the body control module 110) can issue an alarm message to remind that the vehicle is illegally approached or entered.

[0033] During the key domain authentication phase, a primary anti-theft authentication is performed between the body controller 110 and the gateway 120. If the primary anti-theft authentication passes, the basic vehicle functions are activated. The basic vehicle functions described in this application include, but are not limited to, one or more of the following: lighting management function, remote service function, infotainment function, hands-free call function, wiper / washing function, charging function, software update function, comfort experience function, etc. If the primary anti-theft authentication fails, the system 100 confirms that the entire authentication process fails and ends the process. The system 100 can also send an alarm message to alert that the vehicle may be illegally approached or entered.

[0034] Under certain preset conditions, the system 100 can enter the driveline authentication phase. The above preset conditions include passing the primary anti-theft authentication, that is, the basic vehicle functions have been activated. In some embodiments according to the present application, the above preset conditions may further include that the driver's presence has been detected by one or more sensors. The one or more sensors may include one or more of the following: a pressure sensor set on the driver's seat, an image sensor set in front of the driver's seat, and a driver's seat belt status sensor.

[0035] During the driveline authentication phase, a secondary anti-theft authentication is performed between the gateway 120 and the motor controller 130. If the secondary anti-theft authentication passes, the vehicle driving function is activated, that is, the vehicle is allowed to shift to the "drive gear (D gear)" or "reverse gear (R gear)". If the secondary anti-theft authentication fails, the system 100 confirms that the entire authentication process fails and ends the process. The system 100 can also send an alarm message to alert that the vehicle may be illegally approached or entered. In some embodiments according to the present invention, the motor controller 130 may include a front motor controller 131 and a rear motor controller 132. The secondary anti-theft authentication can be performed separately between the front motor controller 131 and the gateway 120, and between the rear motor controller 132 and the gateway 120. If both pass, the vehicle driving function is activated. If both fail or one of them fails, the system 100 confirms that the entire authentication process fails and ends the process.

[0036] The following will use Figure 2 and Figure 3 as examples to introduce in detail the primary anti-theft authentication in the key domain authentication phase and the secondary anti-theft authentication in the driveline authentication phase. It should be noted that the primary anti-theft authentication between the body controller 110 and the gateway 120, and the secondary anti-theft authentication between the gateway 120 and the motor controller 130 (for example, the front motor controller 131 and the rear motor controller 132) can be in the form of either one-way authentication or two-way authentication. The following will take two-way authentication as an example for illustration.

[0037] The following refers to Figure 2 , Figure 2Schematic flowchart of a primary anti-theft authentication process according to an embodiment of the present invention.

[0038] When the body controller 110 determines that the electronic code in the key matches the information preset in the body controller 110, the system 100 will trigger the key domain authentication. Exemplarily, the body controller 110 will use a two-way authentication method to securely transmit the key information to the gateway.

[0039] Exemplarily, during the end-of-line (EOL) inspection of the vehicle, electronic codes such as the vehicle identification number (VIN) and the anti-theft security key (ISK) for vehicle identification and anti-theft authentication are stored in the body controller, the gateway, and the motor controller.

[0040] As Figure 2 shown, the body controller first generates the first authentication information and sends it to the vehicle gateway. Exemplarily, the body controller can generate and store the first random number (RND1), the first seed (Seed1), and encrypt and send them to the gateway together with the vehicle identification number (e.g., the last 8 bytes of the VIN). Exemplarily, the seed information can be stored in the in-vehicle memory during the vehicle production process, and the seed sequence can also be randomly generated during the authentication process and the seed can be generated from the seed sequence.

[0041] After receiving the first authentication information, the gateway decrypts it and extracts the first valid data from the first authentication information for the first authentication. Exemplarily, the gateway can extract Seed1+VIN from RND1+Seed1+VIN and authenticate it using the VIN information stored during the EOL process. If the extracted VIN information matches the stored VIN, the first authentication passes.

[0042] After the first authentication passes, the gateway sends the second authentication information to the body controller. Exemplarily, the gateway can generate and store the second random number (RND2), the second seed (Seed2), and encrypt and send them to the body controller together with the first seed (Seed1).

[0043] After receiving the second authentication information, the body controller decrypts it and extracts the second valid data from the second authentication information for the second authentication. Exemplarily, the gateway can extract Seed2+Seed1 from RND2+Seed2+Seed1 and authenticate it using the previously stored Seed1. If the extracted Seed1 matches the stored Seed1, the second authentication passes.

[0044] After the second authentication is passed, the body controller sends the third authentication information and the key information (KeyData) to the gateway. Exemplarily, the body controller can generate a third random number (RND3), encrypt it together with the key information and Seed2, and send it to the gateway.

[0045] After receiving the third authentication information, the gateway decrypts it and extracts the third valid data from the third authentication information for the third authentication. Exemplarily, the gateway can extract KeyData+Seed2 from RND3+KeyData+Seed2 and authenticate it using the previously stored Seed2. If the extracted Seed2 matches the stored Seed2, the third authentication is passed, the primary anti-theft authentication process ends, and the basic vehicle functions are activated. The body controller securely transmits the key information to the gateway through the above steps using the two-way authentication method to partially activate the vehicle functions.

[0046] The following refers to Figure 3 , Figure 3 which shows a schematic flowchart of the secondary anti-theft authentication process according to an embodiment of the present invention.

[0047] Exemplarily, when one or more of the following conditions are met, the secondary anti-theft authentication between the gateway and the motor controller will be executed: the primary anti-theft authentication has been passed; the driver's presence has been detected.

[0048] As Figure 3 shown, the gateway first generates the fourth authentication information and sends it to the motor controller. Exemplarily, the gateway can generate and store a fourth random number (RND4), a fourth seed (Seed4), and encrypt them together with the vehicle identification number (e.g., the last 8 bytes of the VIN) and send them to the motor controller.

[0049] After receiving the fourth authentication information, the motor controller decrypts it and extracts the fourth valid data from the fourth authentication information for the fourth authentication. Exemplarily, the motor controller can extract Seed4+VIN from RND4+Seed4+VIN and authenticate it using the VIN information stored during the EOL process. If the extracted VIN information matches the stored VIN, the fourth authentication is passed.

[0050] After the fourth authentication is passed, the motor controller sends the fifth authentication information to the gateway. Exemplarily, the motor controller can generate and store a fifth random number (RND5), a fifth seed (Seed5), and encrypt them together with the fourth seed (Seed4) and send them to the gateway.

[0051] After receiving the fifth authentication information, the gateway decrypts it and extracts the fifth valid data from the fifth authentication information for the fifth authentication. Exemplarily, the gateway can extract Seed5+Seed4 from RND5+Seed5+Seed4 and authenticate it using the previously stored Seed4. If the extracted Seed4 matches the stored Seed4, the fifth authentication passes.

[0052] After the fifth authentication passes, the gateway sends the sixth authentication information and key information (KeyData) to the motor controller. Exemplarily, the gateway can generate a sixth random number (RND6), encrypt it together with the key information and Seed5, and send it to the motor controller.

[0053] After receiving the sixth authentication information, the motor controller decrypts it and extracts the sixth valid data from the sixth authentication information for the sixth authentication. Exemplarily, the motor controller can extract KeyData+Seed5 from RND6+KeyData+Seed5 and authenticate it using the previously stored Seed5. If the extracted Seed5 matches the stored Seed5, the sixth authentication passes.

[0054] Exemplarily, the gateway executes the above steps with the front motor controller and the rear motor controller respectively. If both pass, the secondary anti-theft authentication process ends and the vehicle driving function is activated. The gateway securely transmits the key information to the front motor controller and the rear motor controller through the above steps using a two-way authentication method to activate the vehicle's driving function, that is, allowing the vehicle to shift to the "Drive (D gear)" or "Reverse (R gear)".

[0055] The following refers to Figure 4 , Figure 4 FIG. shows a schematic flowchart of a method 400 for vehicle anti-theft authentication according to an embodiment of the present invention.

[0056] In step S10, the body controller determines whether the key information in the vehicle key matches the preset information. If the match is successful, the following key domain authentication phase is entered; if not, the entire authentication process fails and the process ends.

[0057] In step S20, in the case of a match, a primary anti-theft authentication is performed between the body controller and the gateway to determine whether to activate the basic vehicle functions. If the primary anti-theft authentication passes, the basic vehicle functions are activated; if it fails, the entire authentication process fails and the process ends.

[0058] In step S30, when preset conditions are met, a secondary anti-theft authentication is performed between gateway power controllers to determine whether to activate the vehicle driving function. The preset conditions include that the primary anti-theft authentication has been passed, and may also include detecting the presence of a driver. If the secondary anti-theft authentication passes, the vehicle driving function is activated; if it fails, the entire authentication process fails and the process ends.

[0059] The specific steps of the primary anti-theft authentication and the secondary anti-theft authentication have been described in detail above and will not be elaborated here.

[0060] According to another aspect of the present invention, there is provided a computer-readable storage medium having program instructions stored thereon that are executable by a processor. When the program instructions are executed by the processor, the method for vehicle anti-theft authentication according to any one of the embodiments of one aspect of the present invention is performed.
