[0028] To make the above and other features and advantages of this application clearer, the application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art, and are exemplary only, not restrictive.

[0029] In the following description, numerous specific details are set forth to provide a thorough understanding of this application. However, it will be apparent to those skilled in the art that the specific details are not required to practice this application. In other instances, well-known steps or operations have not been described in detail to avoid obscuring this application.

[0030] The anti-theft method for new energy vehicles provided in this application embodiment can be executed by the anti-theft device for new energy vehicles provided in this application embodiment, which can be configured in an electronic device.

[0031] Please see Figure 1 As shown, this application provides an anti-theft method for new energy vehicles, applied to the vehicle controller. The method includes:

[0032] S100, obtains the first anti-theft authentication information and anti-theft status.

[0033] Specifically, the executing entity of this application can be the vehicle controller. That is, after receiving the deactivation signal, the vehicle controller can activate the anti-theft function to perform anti-theft authentication and unlock the vehicle controller and body controller. The deactivation signal can be the vehicle IG-ON signal. Correspondingly, after the vehicle controller activates the anti-theft function based on the deactivation signal, its anti-theft status can be "anti-theft in progress." Furthermore, the first anti-theft authentication information consists of plaintext and a key composed of vehicle controller registration information, body controller anti-theft registration information, and an anti-theft random code. In some embodiments, the anti-theft random code is a random code stored in the vehicle controller and body controller when the vehicle is off the production line. The vehicle controller registration information is the vehicle controller's identity ID (e.g., anti-theft ID), and the body controller registration information is the body controller's identity ID (e.g., anti-theft Exd and anti-theft Exc).

[0034] S200 calculates the first anti-theft verification code based on the first anti-theft authentication information and the anti-theft status.

[0035] Specifically, in this application, the vehicle controller can call the calculation module according to the anti-theft status (such as in anti-theft mode) to perform calculations based on the acquired data. For example, in this step, the vehicle controller can call the calculation module according to the anti-theft status in anti-theft mode and calculate the first anti-theft verification code based on the acquired first anti-theft authentication information.

[0036] S300, verify the first anti-theft verification code and the second anti-theft verification code sent by the vehicle body controller to obtain the first verification result; wherein, the second anti-theft verification code is calculated by the vehicle body controller based on the second anti-theft authentication information.

[0037] Specifically, while the vehicle controller calculates the first anti-theft verification code, the body controller can also calculate the second anti-theft verification code based on the second anti-theft authentication information stored in the body controller. After calculation, the second anti-theft verification code is sent to the vehicle controller, allowing the vehicle controller to verify both the first and second anti-theft verification codes. In some embodiments, the second anti-theft authentication information may also include plaintext and a key composed of vehicle controller registration information, body controller anti-theft information, and an anti-theft random code, to ensure that verification of the first and second anti-theft verification codes is successful when the vehicle controller and body controller are compatible.

[0038] S400 updates the current anti-theft status based on the first verification result to complete the anti-theft authentication of new energy vehicles.

[0039] Specifically, the first verification result can be either "pass" or "fail." Correspondingly, if the first verification result is "pass," the corresponding anti-theft status can be "anti-theft OK"; if the first verification result is "fail," the corresponding anti-theft status can be "anti-theft NG." That is, after updating the current anti-theft status to "anti-theft OK" based on the first verification result, the vehicle controller and body controller can be unlocked; if the current anti-theft status is updated to "anti-theft NG" based on the first verification result, the vehicle controller and body controller remain locked. This achieves anti-theft control for the entire vehicle.

[0040] In summary, this application triggers the calculation module to calculate the first anti-theft verification code by the anti-theft status (such as in anti-theft mode), and verifies the first anti-theft verification code and the second anti-theft verification code. If the verification is successful, the anti-theft status is updated to the anti-theft OK status, thereby unlocking the entire vehicle. Compared with existing solutions, the solution of this application has a clear architecture and reduces the amount of code computation, thus reducing the occupation of the vehicle's computing resources.

[0041] In some embodiments of this application, the current anti-theft status is updated based on the first verification result to complete the anti-theft authentication of the new energy vehicle, including: if the first verification result is successful, updating the current anti-theft status to anti-theft OK status and sending the anti-theft OK status to the vehicle controller to unlock the vehicle controller, and the anti-theft authentication is successful; if the first verification result is unsuccessful, updating the current anti-theft status to anti-theft NG status and sending the anti-theft NG status to the vehicle controller, and the anti-theft authentication fails.

[0042] In some embodiments of this application, in the event of anti-theft authentication failure, the method further includes: receiving a registration request, vehicle registration information, and a first registration verification code generated based on the anti-theft NG status sent by the vehicle controller; wherein the first registration verification code is calculated by the vehicle controller based on the vehicle registration information; and performing anti-theft registration based on the registration request, vehicle registration information, and the first registration verification code.

[0043] Specifically, to avoid initial anti-theft authentication failure due to incomplete authentication information stored by both the vehicle controller and body controller, leading to misjudgments of the decryption result, this embodiment performs anti-theft registration after authentication failure. This exchanges registration information between the vehicle controller and body controller and further verifies them. It should be noted that before the initial registration, the vehicle controller only stores its registration information, and the body controller only stores its registration information. This mismatch between the first anti-theft verification code calculated by the vehicle controller and the second anti-theft verification code calculated by the body controller results in authentication failure.

[0044] In some embodiments of this application, anti-theft registration is performed based on a registration request, vehicle registration information, and a first registration verification code, including: updating the current anti-theft status to an anti-theft registration status based on the received registration request; calculating a second registration verification code based on the anti-theft registration status and vehicle registration information; verifying the first registration verification code and the second registration verification code to obtain a second verification result; and if the second verification result is successful, updating the current anti-theft status to an anti-theft registration completed status and storing the vehicle controller registration information in the vehicle controller.

[0045] Specifically, during the anti-theft registration process, the calculation module can be triggered based on the anti-theft status (anti-theft registration status) to calculate the second registration verification code, and to verify the first and second registration verification codes. If the verification passes, the vehicle controller registration information is stored in the vehicle controller. This enables verification between the vehicle controller and the vehicle controller, as well as the exchange of vehicle controller registration information, facilitating subsequent anti-theft authentication.

[0046] In some embodiments of this application, after verifying the first registration verification code and the second registration verification code to obtain the second verification result, the method further includes: if the second verification result is unsuccessful, updating the current anti-theft status to an anti-theft registration failure status; and in response to the anti-theft registration failure status, issuing an alarm to notify the user that the anti-theft registration has failed.

[0047] In some embodiments of this application, after updating the current anti-theft status to the anti-theft registration completed status and storing the vehicle controller registration information in the vehicle controller when the second verification result is passed, the method further includes: updating the anti-theft status to the anti-theft registration completed status based on the second verification result; calculating a third registration verification code based on the registration completed status and the vehicle controller registration information; and sending the vehicle controller registration information and the third registration verification code to the vehicle controller to store the vehicle controller registration information in the vehicle controller.

[0048] Specifically, during the anti-theft registration process, the calculation module can be triggered to calculate the third registration verification code based on the anti-theft status (anti-theft registration completed status), and the vehicle controller registration information and the third registration verification code can be sent to the body controller. Then, the body controller calculates the fourth registration verification code based on the vehicle controller registration information, and verifies the third and fourth registration verification codes. If the verification is successful, the vehicle controller registration information can be stored in the body controller to complete the anti-theft registration.

[0049] It should be noted that in the scheme of this application, the calculation module can be called based on the anti-theft status to calculate the anti-theft verification code or registration verification code, thereby making the architecture of anti-theft authentication and anti-theft registration in this application clearer. In particular, in some embodiments, different anti-theft statuses can call the same calculation module to further reduce the amount of code computation.

[0050] Please see Figure 2 As shown, this application provides an anti-theft device for a new energy vehicle, the device comprising:

[0051] The acquisition module 201 is used to acquire the first anti-theft authentication information and anti-theft status.

[0052] Specifically, the executing entity of this application can be the vehicle controller. That is, after receiving the deactivation signal, the vehicle controller can activate the anti-theft function to perform anti-theft authentication and unlock the vehicle controller and body controller. The deactivation signal can be the vehicle IG-ON signal. Correspondingly, after the vehicle controller activates the anti-theft function based on the deactivation signal, its anti-theft status can be "anti-theft in progress." Furthermore, the first anti-theft authentication information consists of plaintext and a key composed of vehicle controller registration information, body controller anti-theft registration information, and an anti-theft random code. In some embodiments, the anti-theft random code is a random code stored in the vehicle controller and body controller when the vehicle is off the production line. The vehicle controller registration information is the vehicle controller's identity ID (e.g., anti-theft ID), and the body controller registration information is the body controller's identity ID (e.g., anti-theft Exd and anti-theft Exc).

[0053] The calculation module 202 is used to calculate the first anti-theft verification code based on the first anti-theft authentication information and the anti-theft status.

[0054] Specifically, in this application, the vehicle controller can call the calculation module according to the anti-theft status (such as in anti-theft mode) to perform calculations based on the acquired data. For example, in this step, the vehicle controller can call the calculation module according to the anti-theft status in anti-theft mode and calculate the first anti-theft verification code based on the acquired first anti-theft authentication information.

[0055] The verification module 203 is used to verify the first anti-theft verification code and the second anti-theft verification code sent by the vehicle body controller to obtain the first verification result; wherein, the second anti-theft verification code is calculated by the vehicle body controller based on the second anti-theft authentication information.

[0056] Specifically, while the vehicle controller calculates the first anti-theft verification code, the body controller can also calculate the second anti-theft verification code based on the second anti-theft authentication information stored in the body controller. After calculation, the second anti-theft verification code is sent to the vehicle controller, allowing the vehicle controller to verify both the first and second anti-theft verification codes. In some embodiments, the second anti-theft authentication information may also include plaintext and a key composed of vehicle controller registration information, body controller anti-theft information, and an anti-theft random code, to ensure that verification of the first and second anti-theft verification codes is successful when the vehicle controller and body controller are compatible.

[0057] The authentication module 204 is used to update the current anti-theft status based on the first verification result in order to complete the anti-theft authentication of the new energy vehicle.

[0058] Specifically, the first verification result can be either "pass" or "fail." Correspondingly, if the first verification result is "pass," the corresponding anti-theft status can be "anti-theft OK"; if the first verification result is "fail," the corresponding anti-theft status can be "anti-theft NG." That is, after updating the current anti-theft status to "anti-theft OK" based on the first verification result, the vehicle controller and body controller can be unlocked; if the current anti-theft status is updated to "anti-theft NG" based on the first verification result, the vehicle controller and body controller remain locked. This achieves anti-theft control for the entire vehicle.

[0059] In some embodiments of this application, the authentication module is configured to: update the current anti-theft status to anti-theft OK status and send the anti-theft OK status to the vehicle controller when the first verification result is successful, thereby unlocking the vehicle controller and achieving successful anti-theft authentication; and update the current anti-theft status to anti-theft NG status and send the anti-theft NG status to the vehicle controller when the first verification result is unsuccessful, thereby failing anti-theft authentication.

[0060] In some embodiments of this application, in the event of anti-theft authentication failure, the device further includes: a receiving module, configured to receive a registration request, vehicle registration information, and a first registration verification code generated based on the anti-theft NG status sent by the vehicle body controller; wherein the first registration verification code is calculated by the vehicle body controller based on the vehicle registration information; and a registration module, configured to perform anti-theft registration based on the registration request, vehicle registration information, and the first registration verification code.

[0061] In some embodiments of this application, the registration module is configured to: update the current anti-theft status to an anti-theft registration status based on a received registration request; calculate a second registration verification code based on the anti-theft registration status and vehicle registration information; verify the first registration verification code and the second registration verification code to obtain a second verification result; and if the second verification result is successful, update the current anti-theft status to an anti-theft registration completed status and store the vehicle controller registration information in the vehicle controller.

[0062] In some embodiments of this application, the registration module is further configured to: update the current anti-theft status to an anti-theft registration failure status if the second verification result is unsuccessful; and issue an alarm in response to the anti-theft registration failure status to notify the user that the anti-theft registration has failed.

[0063] In some embodiments of this application, the registration module is further configured to: update the anti-theft status to the anti-theft registration completed status based on the second verification result; calculate the third registration verification code based on the registration completed status and the vehicle controller registration information; and send the vehicle controller registration information and the third registration verification code to the body controller to store the vehicle controller registration information in the body controller.

[0064] In summary, this application triggers the calculation module to calculate the first anti-theft verification code by the anti-theft status (such as in anti-theft mode), and verifies the first anti-theft verification code and the second anti-theft verification code. If the verification is successful, the anti-theft status is updated to the anti-theft OK status, thereby unlocking the entire vehicle.
