Description

Technical Field

[0001] The present application relates to the field of electric vehicle power anti-theft, and specifically to a two-level anti-theft authentication method, device, equipment and computer-readable storage medium. Background Art

[0002] The PEPS system, namely Passive Entry Passive Start, is a keyless system that allows the vehicle to enter and start without the need for traditional key operation. When the driver steps into the designated range, the system can identify the authorized driver of the vehicle and automatically open the door; when leaving the vehicle, the door locks will automatically lock and enter anti-theft status.

[0003] The PEPS system works as follows:

[0004] 1. The user walks near a vehicle in the OFF state (the vehicle is powered off and the doors are locked) with the car key, and the car key sends a low-frequency signal to the low-frequency antenna;

[0005] 2. After receiving the signal, the low-frequency antenna sends a low-frequency trigger signal to the car key;

[0006] 3. After the car key receives the low-frequency trigger signal, the car key and the PEPS system complete the initial handshake verification;

[0007] 4. The car key sends out a high-frequency signal, which contains fixed coded information agreed with the PEPS system in advance;

[0008] 5. After receiving the high-frequency signal, the high-frequency receiver verifies the fixed-code information contained in the high-frequency signal, and when the verification is successful, unlocks the door and wakes up the VCU (Vehicle Control Unit);

[0009] 6. The user needs to trigger the door handle switch by opening the door handle within a certain period of time. After the user opens the door handle and enters the vehicle, the VCU controls the vehicle to power on after receiving the trigger signal of the door handle switch, and switches the vehicle state from OFF to ON (the vehicle is powered on and the doors are unlocked in the ON state). This completes the first-level anti-theft certification of the PEPS system.

[0010] 7. A secondary anti-theft authentication is performed between the car key and the VCU. During the secondary anti-theft authentication, the authentication key sent by PEPS to the VCU needs to be generated based on the fixed coding information used in the primary anti-theft authentication stage. The VCU verifies the authentication key sent by PEPS and, after the verification, determines whether the user has stepped on the brake to start the vehicle within a certain period of time and whether some other vehicle start-up conditions have been met. If so, the vehicle state is switched from the ON state to the READY state (in the READY state, the user has stepped on the brake to start the vehicle and some other vehicle start-up conditions have been met). The secondary anti-theft authentication of the PEPS system is now completed.

[0011] The current intelligent car PEPS system has some problems in application:

[0012] 1. In the first-level anti-theft authentication stage, if the door is unlocked and the VCU is awakened, but the user does not open the door within the specified time, according to the existing PEPS system configuration, the PEPS system will control the door lock and the VCU to sleep, that is, enter the OFF state. However, if the customer has been moving within the sensing range of the car key, the PEPS system will sense the car key after entering the OFF state and unlock the door again, and the VCU will be awakened again. Repeating the above operations will cause the VCU to be awakened continuously and the vehicle to enter the OFF state continuously, resulting in static current consumption. For example, in a real usage scenario, the user parks the car near his office and carries the key with him. After a day of work, he finds that the vehicle battery is exhausted.

[0013] 2. In the secondary anti-theft authentication stage, if the authentication key sent by the PEPS system fails to pass the authentication of the VCU, or although the authentication key sent by the PEPS system passes the authentication of the VCU, but the user does not step on the brake to start the vehicle within the specified time or some other vehicle start conditions are not met as expected, according to the existing PEPS system configuration, the PEPS system will control the vehicle to jump back to the ON state, and the door will still be unlocked, posing a security risk. The VCU will still be in the awake state, resulting in static current consumption.

[0014] 3. In the secondary anti-theft authentication stage, if the authentication key verification between PEPS and VCU cannot be completed due to accidental communication interruption or other reasons, or the user does not step on the brake to start the vehicle for a long time after entering the vehicle, or some other vehicle starting conditions are not met, resulting in the failure of the secondary anti-theft authentication, the vehicle cannot switch to the READY state. In this case, according to the existing PEPS system configuration, the PEPS system will control the vehicle to jump back to the ON state directly. However, when jumping back to the ON state to restart the secondary anti-theft authentication, it is necessary to use the fixed coding information again to generate the authentication key required for the secondary anti-theft authentication stage. At this time, the fixed coding information is often invalid due to time reasons, resulting in the inability to complete the secondary anti-theft authentication normally. This requires the user to manually force the vehicle state to switch back to the OFF state and restart the two-level anti-theft authentication process (including the primary anti-theft authentication and the secondary anti-theft authentication) from the beginning. The user experience is poor, and the user cannot know the specific reason for the authentication failure. Summary of the invention

[0015] The present application provides a two-level anti-theft authentication method, device, equipment and computer-readable storage medium, which can solve the technical problems in the prior art that the existing two-level anti-theft authentication method based on the PEPS system has poor practical application effect and poor user experience.

[0024] After the authentication key sent by the PEPS system to the VCU is verified, if the VCU does not receive the user's brake start signal for a preset period of time, the vehicle state is switched to the OFF state and a vehicle sleep prompt is output;

[0025] After the vehicle sleep prompt is output and the vehicle state is switched to the OFF state, if the vehicle-mounted device wakes up the VCU, the PEPS system restarts the two-level anti-theft authentication.

[0026] In combination with the first aspect, in one implementation, the method further includes:

[0027] When the PEPS system performs authentication key verification in the secondary anti-theft authentication, if the VCU or the PEPS system does not receive the interaction signal sent by the other party, the sending side repeatedly sends the interaction signal to the receiving side, and the number of repeated transmissions does not exceed the preset threshold;

[0028] The interactive signal includes an authentication request signal, a random number, and an authentication key.

[0029] In combination with the first aspect, in one implementation, the method further includes:

[0031] When the PEPS system performs authentication key verification in the secondary anti-theft authentication, if the authentication key sent by the PEPS system to the VCU fails to pass the verification, the corresponding authentication fault code is output;

[0032] After the PEPS system completes the authentication key verification in the secondary anti-theft authentication, if the VCU detects that the necessary vehicle startup conditions are not met as expected, it outputs the corresponding conditional fault code.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] In a first aspect, an embodiment of the present application provides a two-level anti-theft authentication method.

[0048] In one embodiment, the two-level anti-theft authentication method includes:

[0049] When the first level anti-theft certification and the second level anti-theft certification of the PEPS system fail, the vehicle status is controlled to switch to the OFF state;

[0050] After the vehicle status is switched to the OFF state, the fixed-code information sent by the car key is authenticated by the PEPS system and the PEPS system detects that the user opens the door within the specified time, wakes up the vehicle control unit (VCU) and switches the vehicle status to the ON state.

[0051] In this embodiment, in the first-level anti-theft authentication stage, if the door is unlocked and the VCU is awakened, but the user does not open the door within the specified time, according to the existing PEPS system configuration, the PEPS system will control the door to be locked and the VCU to be dormant, that is, enter the OFF state. However, if the customer has been moving within the sensing range of the car key, the PEPS system will sense the car key again after entering the OFF state, unlock the door again, and the VCU will be awakened again. Repeating the above operations will cause the VCU to be awakened continuously and the vehicle to enter the OFF state continuously, resulting in static current consumption. After adopting the technical solution of the present invention, if the user does not open the door within the specified time, the PEPS system will control the vehicle to jump back to the OFF state. In the OFF state, the door is locked to avoid safety risks, and the VCU is dormant to avoid static current consumption. In the first-level anti-theft authentication stage, if the door is unlocked and the VCU is awakened, but the user does not open the door within the specified time, it will enter the OFF state. The next time the car key enters the vehicle detection range, the VCU will be awakened and enter the ON state only when the fixed coded information sent by the car key is authenticated by the PEPS system and the user opens the door with the door handle.

[0052] In the secondary anti-theft authentication stage, if the authentication key sent by the PEPS system fails to pass the authentication of the VCU, or although the authentication key sent by the PEPS system passes the authentication of the VCU, but the user does not step on the brake to start within the specified time or some other vehicle start conditions do not meet expectations, according to the existing PEPS system configuration, the PEPS system will control the vehicle to jump back to the ON state, the door is still in the unlocked state, there is a security risk, the VCU is still in the awakened state, there is static current consumption. After adopting the technical solution of the present invention, if the authentication key sent by the PEPS system fails to pass the authentication of the VCU, the user does not step on the brake to start within the specified time, or some other necessary conditions for vehicle start are not met as expected, the PEPS system will control the vehicle to jump back to the OFF state. In the OFF state, the door is locked to avoid security risks, and the VCU is dormant to avoid static current consumption. After the vehicle status is switched to the OFF state, the first-level anti-theft authentication is directly re-performed to obtain the latest fixed coding information, and the second-level anti-theft authentication is performed based on the latest fixed coding information to avoid failure of the second-level anti-theft authentication due to invalid fixed coding information, thereby increasing the pass probability of the two-level anti-theft authentication. The user does not need to perform any manual operation, thereby improving its automation level and user experience.

[0053] When the first vehicle controller is a VCU, the second vehicle controller is a PEPS system. When the first vehicle controller is a PEPS system, the second vehicle controller is a VCU.

[0054] Furthermore, in one embodiment, the above method further includes:

[0055] When the first-level anti-theft certification of the PEPS system fails, the vehicle state is controlled to switch to the OFF state, which specifically includes the following steps:

[0056] After the door is unlocked and the VCU is awakened, if the VCU does not receive a trigger signal from the door handle switch for a preset period of time, the vehicle state is controlled to switch to the OFF state.

[0057] In this embodiment, in the first-level anti-theft authentication stage, no matter whether the car key fails to pass the verification of the fixed coding information by the PEPS system, or the user does not open the door for a long time after passing the verification, the vehicle is controlled to jump back to the OFF state, the door is locked to improve vehicle safety, and the VCU is dormant to achieve energy saving.

[0058] Furthermore, in one embodiment, the above method further includes:

[0059] After the authentication key sent by the PEPS system to the VCU is verified, if the VCU does not receive the user's brake start signal for a preset period of time, the vehicle state is switched to the OFF state and a vehicle sleep prompt is output.

[0060] After the vehicle sleep prompt is output and the vehicle status is switched to the OFF state, if the vehicle-mounted device wakes up the VCU, the PEPS system restarts the secondary anti-theft authentication.

[0061] In this embodiment, the secondary anti-theft authentication stage of the PEPS system includes a verification stage of the authentication key, a stage of judging whether the following three conditions are met after the authentication key is verified, namely, whether the user steps on the brake to start the vehicle within a specified time period, and whether other necessary conditions for starting the vehicle are met as expected after the user steps on the brake to start the vehicle. If the authentication key is verified, the user steps on the brake to start the vehicle in a specified market, and the necessary vehicle start conditions are met as expected, then it is judged that the secondary anti-theft authentication is passed, and the vehicle state is switched to the READY state at this time. If any one of the above three conditions is not met, then it is judged that the secondary anti-theft authentication is not passed. Regardless of which of the above three conditions causes the failure of the secondary anti-theft authentication of the PEPS system, the vehicle state is switched to the OFF state, and the primary anti-theft authentication is directly re-performed to obtain the latest fixed code information. The secondary anti-theft authentication is performed based on the latest fixed code information, so as to avoid the failure of the secondary anti-theft authentication due to the invalidity of the fixed code information, thereby improving the passing probability of the two-level anti-theft authentication, and the user does not need to perform any manual operation, thereby improving the degree of automation and the user experience.

[0062] Furthermore, in one embodiment, the above method further includes:

[0063] After the authentication key sent by the PEPS system to the VCU is verified, if the VCU does not receive the user's brake start signal for a preset period of time, the vehicle state is switched to the OFF state and a vehicle sleep prompt is output.

[0064] After the vehicle sleep prompt is output and the vehicle state is switched to the OFF state, if the vehicle-mounted device wakes up the VCU, the PEPS system restarts the two-level anti-theft authentication.

[0065] In this embodiment, by outputting a sleep prompt, the user can understand the vehicle status in real time and improve the user experience. Since the user is still in the car at this time, when the user operates the specified vehicle-mounted device, it means that the user needs to use the vehicle. At this time, the vehicle-mounted device wakes up the VCU, and the PEPS system restarts the two-level anti-theft authentication.

[0066] Furthermore, in one embodiment, the above method further includes:

[0067] When the PEPS system performs authentication key verification in the secondary anti-theft authentication, if the VCU or PEPS system does not receive the interactive signal sent by the other party, the sending side repeatedly sends the interactive signal to the receiving side, and the number of repeated transmissions does not exceed the preset threshold.

[0068] The above-mentioned interaction signal includes an authentication request signal, a random number, and an authentication key.

[0069] In this embodiment, the authentication key verification phase in the secondary anti-theft authentication phase generally includes the PEPS system sending an authentication request signal to the VCU, the VCU feeding back a random number to the PEPS system after receiving the authentication request signal, the PEPS system sending an authentication key to the VCU after receiving the random number, and the VCU verifying the authentication key after receiving it. In this process, if there is a communication interruption between the PEPS system and the VCU and the interactive signal fails to be sent due to an accidental communication failure, directly jumping back to the OFF state will waste time and computing resources. In view of this situation, when the sending side sends the interactive signal for the first time and the receiving side does not receive it, the sending side can send the interactive signal again, and the maximum number of times the sending side sends cannot exceed the preset threshold, thereby avoiding the vehicle jumping back to the OFF state due to accidental communication interruption.

[0070] Furthermore, in one embodiment, the above method further includes:

[0071] When the PEPS system performs authentication key verification in the secondary anti-theft authentication, if the VCU or PEPS system does not receive the interactive signal sent by the other party, and the number of repeated transmissions by the sending side has reached the set threshold, a communication fault code corresponding to the interactive signal is output.

[0072] When the PEPS system performs authentication key verification in the secondary anti-theft authentication, if the authentication key sent by the PEPS system to the VCU fails the verification, the corresponding authentication fault code is output.

[0073] After the PEPS system completes the authentication key verification in the secondary anti-theft authentication, if the VCU detects that the necessary vehicle startup conditions are not met as expected, it outputs the corresponding conditional fault code.

[0074] In this embodiment, the maximum number of times the sending side sends cannot exceed the preset threshold, for example, it can only be repeated three times at most. If the receiving side still does not receive the interactive signal after three times, it outputs the corresponding fault code, that is, if the VCU does not receive the authentication request signal, it outputs the fault code for the authentication request signal, and if the PEPS system does not receive the random number, it outputs the fault code for the random number. By adding the fault code for the failure of anti-theft authentication, it is possible to distinguish between the communication problem of sending and receiving information and the failure of the authentication result.

[0075] Furthermore, in one embodiment, the above method further includes:

[0076] The communication fault code, authentication fault code, and conditional fault code are output in the form of voice information and / or visual information.

[0077] In this embodiment, the fault code is output in the form of voice information and / or visual information, which improves the real-time and convenience of the user in obtaining the fault code and improves the user experience.

[0078] In a specific embodiment, referring to Figure 1 , Figure 1 This is a flow chart of a specific embodiment of the two-level anti-theft authentication method of the present application. Figure 1 As shown, the two-level anti-theft authentication method includes:

[0079] Step S1: Determine whether the user is carrying the car key and walking near the vehicle in the OFF state:

[0080] If yes, go to step S2.

[0081] If not, go to step S17.

[0082] Step S2: The vehicle key sends fixed code information to the PEPS system. Step S3: The PEPS system determines whether the fixed code information has passed verification: If so, go to step S4.

[0083] If not, go to step S17.

[0084] Step S4: unlock the vehicle door.

[0085] Step S5: Whether the user opens the door within the specified time:

[0086] If yes, go to step S6.

[0087] If not, go to step S17.

[0088] Step S6: The vehicle state is switched to the ON state.

[0089] Step S7: The PEPS system sends an authentication request signal to the VCU. Step S8: Whether the VCU receives the authentication request signal:

[0090] If yes, go to step S9.

[0091] If not, go to step S17.

[0092] Step S9: VCU sends a random number to the PEPS system.

[0093] Step S10: Whether the PEPS system receives a random number:

[0094] If yes, go to step S11.

[0095] If not, go to step S17.

[0096] Step S11: The PSPS system sends an authentication key to the VCU.

[0097] Step S12: Whether the VCU receives the authentication key:

[0098] If yes, go to step S13.

[0099] If not, go to step S17.

[0100] Step S13: VCU determines whether the authentication key has passed the verification:

[0101] If yes, go to step S14.

[0102] If not, go to step S17.

[0103] Step S14: Whether the user steps on the brake to start within the specified time:

[0104] If yes, go to step S15.

[0105] If not, go to step S17.

[0106] Step S15: VCU determines whether the necessary conditions for charging are met:

[0107] If yes, go to step S16.

[0108] If not, go to step S17.

[0109] Step S16: The vehicle status is switched to READY status.

[0110] Step S17: The vehicle state is switched to the OFF state.

[0111] Among them, the corresponding interactive information can be sent multiple times in step S7, step S9, and step S11. In step S8, step S10, and step S12, if it is judged that the corresponding interactive information has not been received, first remind the other party to send it again. If the other party still does not receive it after sending it multiple times, the corresponding communication fault code is output. In step S13, if it is judged that the authentication key has not passed the verification, the corresponding authentication fault code is output. In step S15, if it is judged that the necessary starting conditions of the vehicle are not met as expected, the corresponding conditional fault code is output.

[0112] In step S14, if it is determined that the user has not stepped on the brake to start the vehicle for a long time, the corresponding fault code can also be output. Moreover, when the vehicle state jumps back to the OFF state because the user has not stepped on the brake to start the vehicle for a long time, the vehicle can be prompted to sleep and the two-level anti-theft authentication can be restarted when the vehicle-mounted device wakes up the VCU.

[0113] If it is determined in step S5 that the user has not opened the car door within the specified time, the process jumps to step S17. After jumping to step S17, the next time the car key enters the vehicle detection range, the two conditions of the fixed coded information sent by the car key passing the authentication of the PEPS system and the user opening the car door through the door handle must be met before the VCU is awakened and enters the ON state, that is, the process jumps to step S6.

[0114] In a second aspect, an embodiment of the present application also provides a two-level anti-theft authentication device.
