Description

Technical Field

[0001] This application relates to the field of vehicle automated electrical inspection technology, and more specifically, to a radio frequency physical key binding method, system, and vehicle. Background Technology

[0002] With the advent of the intelligent era, the level of intelligent vehicle production is also constantly improving. Achieving unmanned and automated vehicle production will be an important milestone in the intelligent process. In particular, the traditional binding process between vehicles and RFID physical keys not only requires manual pressing and holding of the key button to trigger the RFID physical key to enter the learning state, but also, when the RFID physical key enters the learning state, the RFID physical key sends the same learning RFID identifier. In the same environment, when multiple vehicles and multiple RFID physical keys enter the learning process at the same time, the vehicle cannot recognize the specified RFID physical key, resulting in matching other RFID physical keys that are in the learning state. Therefore, only one vehicle can be bound on a production line, and the key learning process for the next vehicle can only be started after binding is completed, resulting in low production efficiency. Summary of the Invention

[0003] This application aims to provide a method, system, and vehicle for binding radio frequency physical keys, in order to solve the problem that related technologies can only bind one vehicle on a production line, and the key learning process for the next vehicle can only be started after binding is completed, resulting in low production efficiency.

[0004] The first aspect of this application provides a radio frequency physical key binding method, applied to a vehicle, including: In response to the radio frequency physical key binding command, a unique radio frequency physical key learning code is generated and encapsulated into the payload to obtain the target payload; the radio frequency physical key is located on the wireless charging coil of the vehicle; The target payload is transmitted to the radio frequency physical key via the vehicle's wireless charging coil, and the feedback signal transmitted by the radio frequency physical key is obtained; wherein, the feedback signal includes a unique radio frequency physical key learning code and a unique key device identifier; The unique radio frequency physical key learning code in the feedback signal is verified to determine the first verification result, and if the first verification result is successful, the unique identifier of the key device is stored. Based on the unique identifier of the key device, a wireless communication connection is established with the radio frequency physical key to achieve the binding of the vehicle and the radio frequency physical key.

[0005] In this solution, the unique radio frequency physical key learning code is encapsulated into the payload, and the encapsulated target payload is sent to the radio frequency physical key through the vehicle's wireless charging coil. This can trigger the binding process of the radio frequency physical key, avoiding the situation of binding the wrong key due to multiple vehicles being bound at the same time, reducing labor costs. By verifying the unique radio frequency physical key learning code in the feedback signal, the vehicle can be bound to its corresponding radio frequency physical key, effectively improving production efficiency and production qualification rate.

[0006] In conjunction with the first aspect, in one possible implementation, generating a unique radio frequency physical key learning code in response to a radio frequency physical key binding command includes: In response to the radio frequency physical key binding command, the vehicle's unique identifier is used as metadata to obtain the first target hash value; Based on the first target hash value, the first message verification code is obtained using the first radio frequency physical key learning key; wherein, the first radio frequency physical key learning key is the same as the second radio frequency physical key learning key stored in the radio frequency physical key; The unique vehicle identifier is concatenated with the first message verification code to obtain a unique radio frequency physical key learning code.

[0007] In this solution, a unique radio frequency physical key learning code is generated by combining the vehicle's unique identifier with the first message verification code. This not only ensures that the binding process between the vehicle and the radio frequency physical key has a unique characteristic, improving the accuracy of the binding, but also enhances the security of radio frequency physical key learning.

[0008] In conjunction with the first aspect, in one possible implementation, the step of encapsulating the unique radio frequency physical key learning code into the payload to obtain the target payload includes: acquiring the target payload by using an amplitude shift keying modulation signal based on the unique radio frequency physical key learning code.

[0009] In this solution, the unique radio frequency physical key learning code is encapsulated in the payload by amplitude shift keying modulation signal, so that the vehicle wireless charging coil can transmit the unique radio frequency physical key learning code to the radio frequency physical key. Since the working range of the vehicle wireless charging coil is small, only the radio frequency physical key placed on the vehicle wireless charging coil can receive the unique radio frequency physical key learning code, thus ensuring the uniqueness of the received signal and enabling the vehicle to be accurately bound to its corresponding radio frequency physical key.

[0010] In conjunction with the first aspect, in one possible implementation, verifying the unique radio frequency entity key learning code in the feedback signal, determining a first verification result, and storing the unique identifier of the key device if the first verification result is successful, includes: The feedback signal is analyzed to obtain the unique radio frequency physical key learning code and the unique identifier of the key device; If the unique radio frequency physical key learning code obtained by parsing is the same as the unique radio frequency physical key learning code generated in response to the radio frequency physical key binding instruction, then the first verification result is determined to be a successful verification, and the unique identifier of the key device is stored. If the unique radio frequency entity key learning code obtained from parsing is different from the unique radio frequency entity key learning code generated in response to the radio frequency entity key binding command, then the first verification result is determined to be verification failure.

[0011] In this solution, the feedback signal is transmitted by the radio frequency physical key through radio frequency signals, which means that the vehicle may receive feedback signals from multiple different radio frequency physical keys at the same time. By verifying the unique radio frequency physical key learning code in the feedback signal, the feedback signal transmitted by the radio frequency physical key corresponding to the vehicle can be accurately identified, thus improving the accuracy of binding multiple vehicles to their respective radio frequency physical keys at the same time.

[0012] In conjunction with the first aspect, in one possible implementation, the radio frequency physical key binding method further includes: if the first verification result is unsuccessful, then refusing to bind with the radio frequency physical key that transmits the feedback signal.

[0013] This solution prevents vehicles from learning other radio frequency physical keys, thus improving the accuracy of vehicle-to-radio frequency physical key binding.

[0014] A second aspect of this application provides a radio frequency physical key binding method, applied to a radio frequency physical key, comprising: The binding signal transmitted by the vehicle through the wireless charging coil is obtained to obtain the target binding signal; the radio frequency physical key is located on the vehicle's wireless charging coil; The target binding signal is parsed to obtain a unique radio frequency physical key learning code; wherein, the unique radio frequency physical key learning code includes a unique vehicle identifier and the first message verification code; Based on the unique vehicle identifier in the learning code of the unique radio frequency physical key obtained through parsing, the second message verification code is obtained; The first message checksum and the second message checksum are verified to obtain a second verification result; If the second verification result is successful, the unique identifier of the key device and the unique radio frequency physical key learning code obtained by parsing will be used to construct a feedback signal; Based on the unique vehicle identifier in the unique radio frequency physical key learning code obtained through parsing, the feedback signal is transmitted to the corresponding vehicle, and the wireless communication connection established by the vehicle is accepted, thereby realizing the initial binding of the radio frequency physical key with the vehicle.

[0015] In this solution, the binding signal transmitted by the vehicle through the wireless charging coil is obtained, which prevents the RF physical key from being affected by the binding process of other vehicles. Furthermore, the unique RF physical key learning code is verified, which ensures the uniqueness of the binding and improves the security of the binding process.

[0016] In conjunction with the second aspect, in one possible implementation, obtaining the second message verification code based on the unique vehicle identifier in the unique radio frequency physical key learning code obtained through parsing includes: The vehicle unique identifier in the unique radio frequency entity key learning code obtained by parsing is used as metadata to obtain the second target hash value; Based on the second target hash value, the second message verification code is obtained using the second radio frequency physical key learning key; wherein, the second radio frequency physical key learning key is the same as the first radio frequency physical key learning key stored in the vehicle.

[0017] In this solution, the second message verification code is calculated using the unique vehicle identifier in the unique radio frequency physical key learning code. The first message verification code in the unique radio frequency physical key learning code can be verified based on the calculated second message verification code, ensuring that the unique radio frequency physical key learning code is transmitted by the vehicle corresponding to the radio frequency physical key, thereby improving the binding accuracy.

[0018] A third aspect of this application provides a radio frequency physical key binding system, applied in the binding process between a vehicle and a radio frequency physical key, comprising: The radio frequency receiving module is used to generate a unique radio frequency physical key learning code in response to the radio frequency physical key binding command, and encapsulate the unique radio frequency physical key learning code into the payload to obtain the target payload. A wireless charging module is used to transmit the target payload to the radio frequency physical key via the vehicle's wireless charging coil, so as to transmit the binding signal to the radio frequency physical key; the radio frequency physical key is located on the vehicle's wireless charging coil; Radio frequency physical key is used to obtain the binding signal transmitted by the vehicle through the wireless charging coil to obtain the target binding signal; The radio frequency physical key is also used to parse the target binding signal to obtain a unique radio frequency physical key learning code; The radio frequency physical key is also used to learn the unique vehicle identifier in the code obtained from the unique radio frequency physical key obtained through parsing, and to obtain the second message verification code; The radio frequency physical key is also used to verify the first message verification code and the second message verification code to obtain a second verification result; The radio frequency physical key is also used to construct a feedback signal by combining the unique identifier of the key device and the parsed unique radio frequency physical key learning code when the second verification result is successful, and to transmit the feedback signal to the radio frequency receiving module. The radio frequency receiving module is also used to acquire the feedback signal transmitted by the radio frequency physical key; wherein the feedback signal includes a unique radio frequency physical key learning code and a unique identifier for the key device; The radio frequency receiving module is also used to verify the unique radio frequency entity key learning code in the feedback signal, determine the first verification result, and store the unique identifier of the key device if the first verification result is successful. The radio frequency receiving module is also used to establish a wireless communication connection with the radio frequency physical key based on the unique identifier of the key device, so as to realize the binding of the vehicle and the radio frequency physical key.

[0019] In this solution, the unique radio frequency (RF) physical key learning code, encapsulated as the target payload, is transmitted to the RF physical key via the vehicle's wireless charging coil through the wireless charging module. This ensures that the vehicle can only initiate binding with the corresponding RF physical key, guaranteeing the uniqueness of the binding process. This allows multiple vehicles to bind to their respective RF physical keys simultaneously. Furthermore, the RF physical key verifies the first message checksum in the unique RF physical key learning code, ensuring security during the binding process. Finally, the RF receiving module verifies the unique RF physical key learning code in the feedback signal transmitted by the RF physical key, eliminating the influence of interference signals and ensuring binding accuracy during the simultaneous binding of multiple vehicles.

[0020] In conjunction with the third aspect, in one possible implementation, the radio frequency physical key binding system further includes: The electrical testing equipment is used to generate an RF physical key binding instruction when the vehicle arrives at the preset work station, and transmit the RF physical key binding instruction to the RF receiving module to start the RF physical key binding process; The electrical testing equipment is also used to query the initial binding result of the vehicle and the radio frequency physical key in real time. When the initial binding result is successful, the radio frequency physical key binding process is terminated, and the vehicle is transferred to the next work station.

[0021] In this solution, the binding process between the vehicle and its corresponding radio frequency physical key is controlled by an electrical inspection device, thus achieving automated binding.

[0022] The fourth aspect of this application provides a vehicle that includes a radio frequency physical key binding system as described in any possible embodiment of the third aspect.

[0023] The technical effects of any implementation method in the fourth aspect can be found in the technical effects of different implementation methods in the third aspect, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] In related technologies, when multiple vehicles and multiple RFID physical keys enter the learning process simultaneously in the same environment, the vehicle cannot recognize the specified RFID physical key, resulting in matching other RFID physical keys that are in the learning state. Therefore, only one vehicle can be bound on a production line, and the key learning process for the next vehicle can only be started after binding is completed, resulting in low production efficiency.

[0028] In view of this, this application proposes a radio frequency physical key binding method. A unique radio frequency physical key learning code is encapsulated in a payload, and the encapsulated target payload is sent to the radio frequency physical key via the vehicle's wireless charging coil. This triggers the binding process of the radio frequency physical key, avoiding the situation of binding the wrong key due to multiple vehicles being bound simultaneously, reducing labor costs. By verifying the unique radio frequency physical key learning code in the feedback signal, the vehicle can be bound to its corresponding radio frequency physical key, effectively improving production efficiency and production qualification rate.

[0029] Please refer to Figure 1 This is a flowchart illustrating a radio frequency physical key binding method provided in an embodiment of this application. This radio frequency physical key binding method is applied to a vehicle and includes: S101. In response to the radio frequency physical key binding command, a unique radio frequency physical key learning code is generated and encapsulated into the payload to obtain the target payload; the radio frequency physical key is located on the vehicle's wireless charging coil.

[0030] The RFID physical key binding command can be a command transmitted from other devices instructing the vehicle to begin the binding process; for example, when the electrical inspection equipment detects that a vehicle has arrived at a preset station, it can send an RFID physical key binding command to the vehicle. Upon receiving the RFID physical key binding command, a unique RFID physical key learning code can be generated using the command as a trigger. This unique RFID physical key learning code can be an encoding that represents the vehicle's identity information, enabling the RFID physical key to identify the vehicle and achieve accurate binding upon receiving it. For example, a unique RFID physical key learning code can be generated using the vehicle's unique identifier.

[0031] The vehicle wireless charging coil is the structure used by the in-vehicle wireless charger to achieve wireless charging. The operating range of the vehicle wireless charging coil is typically limited by coil alignment and distance. It usually requires the device to be aligned with the wireless charging coil, with a distance generally a few millimeters, to ensure that the device placed on the wireless charging coil can accurately receive the energy transmitted by the coil. Therefore, placing the RFID physical key above the wireless charging coil ensures that the RFID physical key can receive the signal transmitted by its vehicle. In related technologies, the wireless charging coil is typically used to charge devices and cannot directly transmit signals. Therefore, the unique RFID physical key learning code can be encapsulated in the payload to obtain the target payload. The vehicle wireless charging coil can then transmit the unique RFID physical key learning code to the RFID physical key based on the target payload. This ensures that the RFID physical key can receive the unique RFID physical key learning code and achieves one-to-one data transmission between the vehicle and the RFID physical key, preventing the RFID physical key from receiving signals from other vehicles and fundamentally avoiding the situation of incorrect key binding caused by multiple vehicles being bound simultaneously.

[0032] S102. The target payload is transmitted to the radio frequency physical key through the vehicle's wireless charging coil, and the feedback signal transmitted by the radio frequency physical key is obtained; wherein, the feedback signal includes a unique radio frequency physical key learning code and a unique identifier for the key device.

[0033] The vehicle's wireless charging coil uses electromagnetic induction to load and transmit the target payload. During payload loading, the coil generates a magnetic field while simultaneously embedding the unique radio frequency (RF) key's learning code into the electromagnetic waves, achieving data transmission through modulation. When the RF key approaches the coil, its internal circuitry receives and decodes these signals, completing the data loading process. This signal transmission not only eliminates the need for circuit connections but also effectively prevents the RF key from receiving signals from other vehicles, improving communication efficiency and security, and initially ensuring the accuracy of the RF key binding.

[0034] When the RFID physical key receives a unique RFID physical key learning code, it usually verifies this unique RFID physical key learning code. After successful verification, a feedback signal is generated. In order for the vehicle to determine whether the feedback signal is transmitted by its corresponding RFID physical key, the feedback signal should usually include the unique RFID physical key learning code. After verifying that the unique RFID physical key learning code is correct, it means that the vehicle and the RFID physical key have exchanged their respective unique identifiers. In subsequent communication, they can communicate through the unique identifiers, thereby realizing the binding of the vehicle and the RFID physical key. This is applicable to scenarios where multiple vehicles are bound to their respective RFID physical keys at the same time.

[0035] S103. Verify the unique radio frequency physical key learning code in the feedback signal, determine the first verification result, and if the first verification result is successful, store the unique identifier of the key device.

[0036] The unique radio frequency physical key learning code in the feedback signal is sent by the radio frequency physical key. The unique radio frequency physical key learning code in the radio frequency physical key is obtained by parsing the signal sent by the vehicle's wireless charging coil. If the unique radio frequency physical key learning code in the feedback signal is the same as the generated unique radio frequency physical key learning code, it can be determined that the feedback signal is transmitted by the radio frequency physical key located inside the vehicle. Therefore, the first verification result can be determined as verification passed.

[0037] If the first verification result is successful, the unique identifier of the key device is stored locally, so that the vehicle has a unique identifier of the key device corresponding to the radio frequency physical key. At the same time, the radio frequency physical key also has a unique vehicle identifier, which can be used for communication in subsequent communication processes based on the unique identifier held.

[0038] S104. Based on the unique identifier of the key device, establish a wireless communication connection with the radio frequency physical key to realize the binding of the vehicle and the radio frequency physical key.

[0039] With a unique identifier for the key device, the RFID physical key can be authenticated during both signal transmission and reception, establishing a wireless communication connection and ensuring uniqueness of the binding. This effectively allows multiple vehicles to be bound to their respective RFID physical keys simultaneously. In subsequent communication, received vehicle control signals can be parsed to determine if the unique identifier for the key device matches a stored one. If so, the vehicle control signal can be executed to control the vehicle; otherwise, execution can be refused to prevent interference from other signals.

[0040] In the actual binding process, incomplete signal transmission or garbled signal transmission may occur. This can prevent the RFID physical key from accurately establishing a connection with the vehicle, thus failing to achieve binding. Therefore, before the vehicle and the RFID physical key are successfully bound, the method described in steps S101 to S104 should be executed after each binding time period to ensure successful binding between the vehicle and the RFID physical key.

[0041] In this embodiment, a unique radio frequency physical key learning code is encapsulated into a payload, and the encapsulated target payload is sent to the radio frequency physical key through the vehicle's wireless charging coil. This can trigger the binding process of the radio frequency physical key, avoiding the situation of binding the wrong key due to multiple vehicles being bound at the same time, reducing labor costs. By verifying the unique radio frequency physical key learning code in the feedback signal, the vehicle can be bound to its corresponding radio frequency physical key, effectively improving production efficiency and production qualification rate.

[0042] Please refer to Figure 2 This is a schematic diagram illustrating the process of generating a unique radio frequency physical key learning code provided in an embodiment of this application. Figure 2 As shown, in response to the RFID physical key binding command, a unique RFID physical key learning code is generated, including: S201. In response to the radio frequency physical key binding command, the vehicle's unique identifier is used as metadata to obtain the first target hash value.

[0043] When an RFID physical key binding command is present, the generation process of a unique RFID physical key learning code can be triggered. This allows the vehicle unique identifier (VIN) stored locally on the vehicle to be obtained, and the VIN can be used as metadata to obtain the first target hash value. For example, SHA256 (Secure Hash Algorithm 256-bit) can be used to calculate the VIN to obtain the first target hash value.

[0044] S202. Based on the first target hash value, obtain the first message authentication code (MAC) using the first radio frequency entity key learning key; wherein, the first radio frequency entity key learning key is the same as the second radio frequency entity key learning key stored in the radio frequency entity key.

[0045] To ensure the security of the vehicle's unique identifier during transmission, a first message verification code can be obtained based on the first target hash value. This allows the RFID physical key to verify the vehicle's unique identifier using the first message verification code, preventing transmission errors or tampering and enhancing the security of the binding between the vehicle and the RFID physical key. To verify the vehicle's unique identifier, the vehicle pre-stores a first RFID physical key learning key, and the RFID physical key pre-stores a second RFID physical key learning key. The first and second RFID physical key learning keys are identical. Therefore, the first message verification code obtained using the first RFID physical key learning key can be verified by the second RFID physical key within the RFID physical key, thus verifying the vehicle's unique identifier. For example, the first message verification code can be obtained by performing an AES_ECB (Advanced Encryption Standard - Electronic Code Book) operation on the first target hash value using the first RFID physical key learning key.

[0046] S203. Concatenate the vehicle's unique identifier with the first message verification code to obtain the unique radio frequency physical key learning code.

[0047] The unique RFID physical key learning code is obtained by concatenating the vehicle's unique identifier and the first message verification code. This allows the RFID physical key to use the second RFID physical key to perform hash processing and key processing on the vehicle's unique identifier in sequence to obtain the second message verification code. The first message verification code can then be verified based on the second message verification code. This not only ensures that the binding process between the vehicle and the RFID physical key has a unique feature, improving the accuracy of the binding, but also enhances the security of RFID physical key learning.

[0048] In one possible implementation, the unique radio frequency physical key learning code is encapsulated into the payload to obtain the target payload, including: acquiring the target payload by using amplitude shift keying (ASK) modulation signal based on the unique radio frequency physical key learning code.

[0049] For example, ASK modulation can be configured as follows: (1) Baseband signal: converts data into binary: 1010101010 (each bit lasts 1ms), high level represents 1 (+V), low level represents 0 (0V).

[0050] (2) ASK signal: Low frequency amplitude keying (ASK) is used to avoid interference with the main charging frequency, and a 125kHz carrier frequency is used.

[0051] (3) Carrier period: 8μs (125kHz = 1 / 125000 = 8μs / period).

[0052] (4) Frame structure: [synchronization header][data packet][CRC check].

[0053] (5) Synchronization header: A predefined unique sequence used by the Rx end (receiver) to capture signals.

[0054] (6) Transmission rate: ≤50kbps (limited by Qi charging frequency and signal-to-noise ratio).

[0055] (7) Use Manchester encoding to enhance anti-interference capability.

[0056] By using amplitude shift keying modulation (APS) to modulate the signal, the unique radio frequency (RF) physical key learning code is encapsulated in the payload. This allows the vehicle's wireless charging coil to transmit the unique RF physical key learning code to the RF physical key. Since the working range of the vehicle's wireless charging coil is small, only the RF physical key placed on the vehicle's wireless charging coil can receive the unique RF physical key learning code, thus ensuring the uniqueness of the received signal and enabling the vehicle to be accurately bound to its corresponding RF physical key.

[0057] In one possible implementation, the unique radio frequency physical key learning code in the feedback signal is verified to determine a first verification result, and if the first verification result is successful, the unique identifier of the key device is stored, including: The feedback signal is analyzed to obtain the unique radio frequency physical key learning code and the unique identifier of the key device.

[0058] After the RFID physical key verifies the unique RFID physical key learning code, it should transmit its own information, namely the unique identifier of the key device, to the vehicle corresponding to the RFID physical key. However, in scenarios where multiple vehicles are simultaneously bound to RFID physical keys, the vehicles do not store information related to the RFID physical keys. Therefore, the unique RFID physical key learning code in the feedback signal of the RFID physical key can be verified to ensure the accuracy of the bound RFID physical key.

[0059] If the unique radio frequency physical key learning code obtained by parsing is the same as the unique radio frequency physical key learning code generated in response to the radio frequency physical key binding command, then the first verification result is determined to be successful, and the storage key device unique identifier is determined. The unique radio frequency physical key learning code generated in response to the radio frequency physical key binding command is data generated by the vehicle itself, while the unique radio frequency physical key learning code obtained by parsing is data transmitted by the radio frequency physical key. The unique radio frequency physical key learning code in the radio frequency physical key comes from its corresponding vehicle. Therefore, only the unique radio frequency physical key learning code in the feedback signal transmitted by the radio frequency physical key located inside the vehicle can be verified, ensuring the accuracy of the binding between the vehicle and the radio frequency physical key.

[0060] If the unique radio frequency entity key learning code obtained from parsing is different from the unique radio frequency entity key learning code generated in response to the radio frequency entity key binding command, then the first verification result is determined to be verification failure.

[0061] In one possible implementation, the radio frequency physical key binding method further includes: refusing binding with the radio frequency physical key that transmits feedback signals if the first verification result fails.

[0062] The feedback signal is transmitted by the RFID physical key via radio frequency (RF) signals. This indicates that a vehicle may receive feedback signals from multiple different RFID physical keys simultaneously. By verifying the unique RFID physical key learning code within the feedback signal, the feedback signal transmitted by the RFID physical key corresponding to the vehicle can be accurately identified, improving the accuracy of binding multiple vehicles to their respective RFID physical keys simultaneously. Conversely, if the first verification result fails, binding with the RFID physical key transmitting the feedback signal is rejected, preventing the vehicle from learning other RFID physical keys and further improving the accuracy of vehicle-RFID physical key binding.

[0063] Please refer to Figure 3 Based on the same inventive concept, another embodiment of this application also provides another radio frequency physical key binding method, applied to the radio frequency physical key end, the method comprising: S301. Obtain the binding signal transmitted by the vehicle through the wireless charging coil to obtain the target binding signal. The radio frequency physical key is located on the vehicle's wireless charging coil.

[0064] The binding signal transmitted by the vehicle through the wireless charging coil is essentially a signal with a unique vehicle identifier, which can be used to verify the vehicle's identity. The RFID physical key, located on the vehicle's wireless charging coil, ensures that it only receives signals transmitted by its corresponding vehicle, thus enabling it to transmit feedback signals to that vehicle.

[0065] S302. Analyze the target binding signal to obtain the unique radio frequency physical key learning code. The unique radio frequency physical key learning code includes the vehicle's unique identifier and the first message verification code.

[0066] The unique RFID physical key learning code is obtained through parsing. This unique RFID physical key learning code has a unique vehicle identifier, which can establish an accurate connection with the corresponding vehicle during subsequent communication. The first message verification code is obtained from the vehicle's unique identifier and can be used to verify the vehicle's unique identifier, ensuring the security of the binding process.

[0067] S303. Based on the unique vehicle identifier in the learning code of the unique radio frequency physical key obtained by parsing, obtain the second message verification code.

[0068] The method for obtaining the first message verification code is the same as the method for obtaining the second message verification code. For example, the second message verification code can be obtained by using the unique vehicle identifier in the unique radio frequency physical key learning code as a basis, performing hash processing and key processing in sequence.

[0069] S304. Verify the first message check code and the second message check code to obtain the second verification result.

[0070] If the first message verification code and the second message verification code are the same, it can be assumed that the vehicle unique identifier in the unique radio frequency physical key learning code is correct, which ensures the security of the binding process and avoids invalid binding due to incomplete or chaotic signal transmission.

[0071] S305. If the second verification result is successful, the unique identifier of the key device and the unique radio frequency physical key learning code obtained by parsing are used to construct a feedback signal.

[0072] When an RFID physical key transmits feedback signals to a vehicle, it can only do so via RFID signals. In scenarios where multiple vehicles are simultaneously bound to RFID physical keys, multiple RFID physical keys may transmit feedback signals at the same time. Therefore, the unique identifier of the key device and the unique RFID physical key learning code obtained by parsing can be used to construct the feedback signal. This not only enables the vehicle to recognize the corresponding RFID physical key, but also stores the unique identifier of the key device corresponding to the RFID physical key, thus facilitating the establishment of a communication connection in the future.

[0073] S306. Based on the unique vehicle identifier in the learning code of the unique radio frequency physical key obtained by parsing, the feedback signal is transmitted to the corresponding vehicle, and the wireless communication connection established by the vehicle is accepted, so as to realize the initial binding of the radio frequency physical key with the vehicle.

[0074] Acquiring the binding signal transmitted by the vehicle through the wireless charging coil ensures that the RFID physical key is not affected by the binding process of other vehicles, and verifies the unique RFID physical key learning code, thus guaranteeing the uniqueness of the binding and improving the security of the binding process.

[0075] In one possible implementation, a second message verification code is obtained based on the vehicle's unique identifier in the learned code of the unique radio frequency physical key obtained through parsing, including: The unique vehicle identifier in the unique radio frequency entity key learning code obtained from the parsing is used as metadata to obtain the second target hash value.

[0076] For example, the unique vehicle identifier in the learning code of the unique radio frequency physical key obtained by parsing can be used as metadata, and SHA256 can be used for hash calculation to obtain the second target hash value.

[0077] Based on the second target hash value, the second message verification code is obtained using the second radio frequency physical key learning key. The second radio frequency physical key learning key is the same as the first radio frequency physical key learning key stored in the vehicle.

[0078] To ensure the security of the vehicle's unique identifier during transmission, a second message verification code can be obtained based on the second target hash value. This allows the RFID physical key to verify the vehicle's unique identifier using the second message verification code, preventing transmission errors or tampering and enhancing the binding security between the vehicle and the RFID physical key. To verify the vehicle's unique identifier, the RFID physical key pre-stores a second RFID physical key learning key, while the vehicle pre-stores a first RFID physical key learning key. The second RFID physical key learning key is identical to the first RFID physical key learning key. Therefore, the second message verification code obtained using the second RFID physical key learning key can verify the first message verification code transmitted by the vehicle, thus verifying the vehicle's unique identifier. For example, the second RFID physical key learning key can be used to perform an AES_ECB operation on the second target hash value to obtain the second message verification code. Then, the calculated second message verification code can be used to verify the first message verification code in the unique RFID physical key learning code, ensuring that the unique RFID physical key learning code is transmitted by the vehicle corresponding to the RFID physical key, improving binding accuracy.

[0079] Please refer to Figure 4 Based on the same inventive concept, another embodiment of this application also provides an RFID physical key binding system, applied in the binding process between a vehicle and an RFID physical key. The system includes: The radio frequency receiving module 401 is used to generate a unique radio frequency physical key learning code in response to the radio frequency physical key binding command, and encapsulate the unique radio frequency physical key learning code into the payload to obtain the target payload.

[0080] For example, in response to an RFID physical key binding instruction, generating a unique RFID physical key learning code includes: in response to the RFID physical key binding instruction, using the vehicle's unique identifier as metadata to obtain a first target hash value; based on the first target hash value, using a first RFID physical key learning key to obtain a first message verification code; wherein the first RFID physical key learning key is the same as the second RFID physical key learning key stored in the RFID physical key; and concatenating the vehicle's unique identifier with the first message verification code to obtain a unique RFID physical key learning code.

[0081] For example, encapsulating the unique radio frequency physical key learning code into the payload to obtain the target payload includes: acquiring the target payload using an amplitude shift keying modulation signal based on the unique radio frequency physical key learning code.

[0082] The wireless charging module 402 is used to transmit the target payload to the radio frequency physical key 403 via the vehicle's wireless charging coil, so as to transmit the binding signal to the radio frequency physical key 403. The radio frequency physical key 403 is located on the vehicle's wireless charging coil.

[0083] Radio frequency physical key 403 is used to obtain the binding signal transmitted by the vehicle through the wireless charging coil to obtain the target binding signal.

[0084] The radio frequency physical key 403 is also used to analyze the target binding signal to obtain a unique radio frequency physical key learning code.

[0085] The radio frequency physical key 403 is also used to obtain the second message verification code based on the vehicle unique identifier in the learning code of the unique radio frequency physical key obtained by parsing.

[0086] For example, obtaining a second message verification code based on the vehicle unique identifier in the parsed unique radio frequency physical key learning code includes: using the vehicle unique identifier in the parsed unique radio frequency physical key learning code as metadata to obtain a second target hash value; and using a second radio frequency physical key learning key based on the second target hash value to obtain a second message verification code; wherein the second radio frequency physical key learning key is the same as the first radio frequency physical key learning key stored in the vehicle.

[0087] The radio frequency physical key 403 is also used to verify the first message check code and the second message check code to obtain the second verification result.

[0088] The radio frequency physical key 403 is also used to construct a feedback signal by combining the unique identifier of the key device and the unique radio frequency physical key learning code obtained by parsing when the second verification result is successful, and to transmit the feedback signal to the radio frequency receiving module 401.

[0089] The radio frequency receiving module 401 is also used to acquire the feedback signal transmitted by the radio frequency physical key 403. The feedback signal includes a unique radio frequency physical key learning code and a unique identifier for the key device.

[0090] The radio frequency receiving module 401 is also used to verify the unique radio frequency physical key learning code in the feedback signal, determine the first verification result, and store the unique identifier of the key device if the first verification result is successful.

[0091] For example, verifying the unique radio frequency physical key learning code in the feedback signal to determine a first verification result, and storing the unique identifier of the key device if the first verification result is successful, includes: parsing the feedback signal to obtain the unique radio frequency physical key learning code and the unique identifier of the key device; if the parsed unique radio frequency physical key learning code is the same as the unique radio frequency physical key learning code generated in response to the radio frequency physical key binding instruction, then the first verification result is determined to be successful, and the unique identifier of the key device is stored; if the parsed unique radio frequency physical key learning code is different from the unique radio frequency physical key learning code generated in response to the radio frequency physical key binding instruction, then the first verification result is determined to be unsuccessful, and if the first verification result is unsuccessful, then the binding with the radio frequency physical key transmitting the feedback signal is rejected.

[0092] The radio frequency receiving module 401 is also used to establish a wireless communication connection with the radio frequency physical key 403 based on the unique identifier of the key device, so as to realize the binding of the vehicle and the radio frequency physical key 403.

[0093] The wireless charging module 402 transmits the unique radio frequency physical key learning code, which is encapsulated as the target payload, to the radio frequency physical key 403 via the vehicle's wireless charging coil. This ensures that the vehicle can only initiate binding with the corresponding radio frequency physical key 403, guaranteeing the uniqueness of the binding process. This allows multiple vehicles to bind to their respective radio frequency physical keys 403 simultaneously. Furthermore, the radio frequency physical key 403 verifies the first message check code in the unique radio frequency physical key learning code, ensuring security during the binding process. Finally, the radio frequency receiving module 401 verifies the unique radio frequency physical key learning code in the feedback signal transmitted by the radio frequency physical key 403. This eliminates the influence of interference signals during the simultaneous binding of multiple vehicles, ensuring the accuracy of the binding process.

[0094] The radio frequency physical key binding system provided in this application embodiment can execute the above-described method and technical solution. Its principle and beneficial effects are similar, and will not be repeated here.

[0095] In one possible implementation, the radio frequency physical key 403 binding system further includes: The electrical testing equipment 404 is used to generate an RF physical key binding instruction when the vehicle arrives at the preset work station, and transmit the RF physical key binding instruction to the RF receiving module 401 to start the RF physical key binding process.

[0096] The electrical testing equipment 404 is also used to query the binding result of the vehicle and the radio frequency physical key 403 in real time. When the initial binding result is successful, the radio frequency physical key binding process is terminated, and the vehicle is transferred to the next work station.

[0097] The binding process between the vehicle and its corresponding RFID physical key is controlled by the 404 electrical testing equipment, which achieves automated binding and ensures that the vehicle can be successfully bound to the corresponding RFID physical key before proceeding with subsequent processes.
