Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically the control method, device, equipment, and storage medium for MCU anti-theft in new energy vehicles. Background Technology

[0002] In recent years, new energy vehicles have become increasingly popular due to their advantages such as environmental friendliness and energy conservation. Among new energy vehicles, vehicle anti-theft is a crucial factor affecting overall vehicle safety and requires focused attention during development. Currently, the anti-theft strategy for electric vehicles relies on the interaction of anti-theft signals between the Vehicle Control Unit (VCU) and Body Controller (BCM) along with an electronic steering column lock to achieve comprehensive anti-theft protection. However, existing anti-theft strategies are ineffective and costly. Summary of the Invention

[0003] This invention provides a control method, device, equipment, and storage medium for MCU anti-theft in new energy vehicles. It increases interactive signals, realizes vehicle-wide anti-theft, reduces vehicle cost, and does not affect other vehicle performance. It is suitable for all new energy vehicle models and solves the above-mentioned problems of existing MCU anti-theft methods.

[0004] The technical solution of this invention is described below in conjunction with the accompanying drawings:

[0005] In a first aspect, embodiments of the present invention provide a control method for anti-theft of MCU in new energy vehicles, including controlling the MCU and controlling the BCM;

[0006] The specific method for controlling the MCU is as follows:

[0007] a1) The authentication process is initiated by the MCU; when the power is switched to IGON, the MCU generates a set of 4-byte random numbers, denoted as random number B;

[0008] a2) The MCU sends the random number B as an authentication request to the BCM;

[0009] a3) The MCU internally uses the function F(x,sk) to process the random number B and generate the encrypted authentication data C1 = F(B,sk) corresponding to the random number B;

[0010] a4) If the MCU does not receive a response signal from the BCM within time T, the MCU must retry sending the authentication request; if the MCU still does not receive a response signal from the BCM after sending 6 consecutive authentication requests, the MCU will determine that the BCM does not respond to the MCU's authentication request and the authentication will fail.

[0011] a5) If a response signal C2 is received from the BCM within time T, the encrypted authentication data C1 and C2 need to be compared. If C1 = C2, the authentication is successful and the MCU sends MessageType = AlogrithmPass to the BCM. If C1 ≠ C2, the authentication fails. If the authentication fails ≥ 2 times, the MCU sends MessageType = AlogrithmFail to the BCM. Otherwise, the authentication request must be retried.

[0012] The specific method for controlling the BCM is as follows:

[0013] b1) If the BCM does not receive an authentication request signal from the MCU within 2 seconds after IGON, the BCM will determine that "the MCU has not sent an authentication request" and record this DTC.

[0014] b2) After receiving the random number B, the BCM uses the function F(X,sk) to encrypt B, generating encrypted authentication data C2 = F(B,sk) corresponding to the random number B, and sends Key = <c2>;

[0015] b3) If the BCM sends encrypted authentication data to the MCU and does not receive the authentication result from the MCU within 2 seconds, or does not receive the authentication request resent by the MCU, the BCM determines that the MCU authentication result transmission has timed out and records this DTC.

[0016] b4) If the BCM receives the authentication result MessageType=AlogrithmPass, no action is required;

[0017] If the BCM receives the authentication result MessageType=AlogrithmFail, it sends a SecurityVerificationError_BCM=Error signal to the IC to indicate that the anti-theft authentication has failed.

[0018] If the BCM receives a re-issued authentication request from the MCU, it will restart the authentication process.

[0019] Furthermore, in step a5), the retry requirements for retrying the authentication request are as follows:

[0020] A. The time interval between two consecutive authentication requests issued by the MCU is R;

[0021] B. The MCU can retry sending the authentication request at most once consecutively, and a total of 2 times; however, if the BCM responds to any authentication request, the MCU will not retry sending the authentication request.

[0022] C. If the MCU still does not receive a response signal from the BCM after sending two consecutive authentication requests, the MCU will determine that "the BCM authentication encryption data is incorrect" and record this DTC.

[0023] Secondly, embodiments of the present invention provide a control device for anti-theft of MCUs in new energy vehicles, comprising:

[0024] MCU control module, used to control the MCU;

[0025] The BCM control module is used to control the BCM.

[0026] Furthermore, the MCU control module includes:

[0027] The first authentication module is used to enable the authentication process to be initiated by the MCU; when the power is switched to IGON, the MCU generates a set of 4-byte random numbers, denoted as random number B.

[0028] The first authentication request module is used by the MCU to send the random number B as an authentication request to the BCM.

[0029] The first processing module is used by the MCU to process the random number B using the function F(x,sk) to generate the encrypted authentication data C1 = F(B,sk) corresponding to the random number B.

[0030] The first judgment module is used to determine that if the MCU does not receive a response signal from the BCM within time T, the MCU must retry sending the authentication request; if the MCU sends an authentication request 6 times in a row and still does not receive a response signal from the BCM, the MCU will determine that the BCM does not respond to the MCU's authentication request and the authentication will fail.

[0031] The second judgment module is used to compare the encrypted authentication data C1 and C2 if a response signal C2 is received from the BCM within time T. If C1 = C2, the authentication is successful, and the MCU sends MessageType = AlogrithmPass to the BCM. If C1 ≠ C2, the authentication fails. If the authentication fails ≥ 2 times, the MCU sends MessageType = AlogrithmFail to the BCM. Otherwise, the authentication request must be retried.

[0032] Furthermore, the BCM control module includes:

[0033] The third judgment module is used to determine "MCU has not sent an authentication request signal" if the BCM does not receive an authentication request signal from the MCU within 2 seconds after IGON, and to record this DTC.

[0034] The encryption module is used by the BCM to encrypt a random number B using the function F(X,sk), generating encrypted authentication data C2 = F(B,sk) corresponding to the random number B, and then sending the Key = <c2>;

[0035] The fourth judgment module is used to determine that the MCU authentication result transmission timeout occurs if the BCM does not receive the authentication result from the MCU within 2 seconds after sending encrypted authentication data to the MCU, or does not receive the authentication request resent by the MCU. This DTC is then recorded.

[0036] The fifth judgment module is used so that if the BCM receives the authentication result MessageType=AlogrithmPass, no action is required;

[0037] If the BCM receives the authentication result MessageType=AlogrithmFail, it sends a SecurityVerificationError_BCM=Error signal to the IC to indicate that the anti-theft authentication has failed.

[0038] If the BCM receives a re-issued authentication request from the MCU, it will restart the authentication process.

[0039] Thirdly, embodiments of the present invention also provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement a control method for anti-theft of a new energy vehicle MCU as described in any of the embodiments of the present invention.

[0040] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements a control method for anti-theft of a new energy vehicle MCU as described in any of the embodiments of the present invention.

[0041] The beneficial effects of this invention are as follows:

[0042] This invention only requires changing the MCU and BCM control strategies and adding interactive signals to achieve vehicle anti-theft and reduce the overall vehicle cost; it does not affect other vehicle performance and is suitable for all new energy vehicle models.

[0055] See Figure 1 This embodiment is applicable to the anti-theft situation of MCU in new energy vehicles. The method can be executed by the control device for the anti-theft of the new energy vehicle MCU in this embodiment. This device can be implemented in software and / or hardware, such as... Figure 1 As shown, this method specifically includes controlling the MCU and controlling the BCM;

[0056] The specific method for controlling the MCU is as follows:

[0058] a2) The MCU sends the random number B as an authentication request to the BCM;

[0059] a3) The MCU internally uses the function F(x,sk) to process the random number B and generate the encrypted authentication data C1 = F(B,sk) corresponding to the random number B;

[0060] a4) If the MCU does not receive a response signal from the BCM within time T, the MCU must retry sending the authentication request; if the MCU still does not receive a response signal from the BCM after sending 6 consecutive authentication requests, the MCU will determine that the BCM does not respond to the MCU's authentication request and the authentication will fail.

[0061] a5) If a response signal C2 is received from the BCM within time T, the encrypted authentication data C1 and C2 need to be compared. If C1 = C2, the authentication is successful and the MCU sends MessageType = AlogrithmPass to the BCM. If C1 ≠ C2, the authentication fails. If the authentication fails ≥ 2 times, the MCU sends MessageType = AlogrithmFail to the BCM. Otherwise, the authentication request must be retried.

[0062] The retry requirements for issuing the authentication request are as follows:

[0064] B. The MCU can retry sending the authentication request at most once consecutively, and a total of 2 times; however, if the BCM responds to any authentication request, the MCU will not retry sending the authentication request.

[0065] C. If the MCU still does not receive a response signal from the BCM after sending two consecutive authentication requests, the MCU will determine that "the BCM authentication encryption data is incorrect" and record this DTC.

[0066] The specific method for controlling the BCM is as follows:

[0068] b2) After receiving the random number B, the BCM uses the function F(X,sk) to encrypt B, generating encrypted authentication data C2 = F(B,sk) corresponding to the random number B, and sends Key = <c2>;

[0069] b3) If the BCM sends encrypted authentication data to the MCU and does not receive the authentication result from the MCU within 2 seconds, or does not receive the authentication request resent by the MCU, the BCM determines that the MCU authentication result transmission has timed out and records this DTC.

[0070] b4) If the BCM receives the authentication result MessageType=AlogrithmPass, no action is required;

[0071] If the BCM receives the authentication result MessageType=AlogrithmFail, it sends a SecurityVerificationError_BCM=Error signal to the IC to indicate that the anti-theft authentication has failed.

[0081] The second judgment module is used to compare the encrypted authentication data C1 and C2 if a response signal C2 is received from the BCM within time T. If C1 = C2, the authentication is successful, and the MCU sends MessageType = AlogrithmPass to the BCM. If C1 ≠ C2, the authentication fails. If the authentication fails ≥ 2 times, the MCU sends MessageType = AlogrithmFail to the BCM. Otherwise, the authentication request must be retried.
