Description

Technical Field

[0001] This application relates to the field of vehicle start control technology, and in particular to a vehicle authorized start method, system, device and computer-readable storage medium. Background Technology

[0002] As vehicles continue to evolve, users are placing higher demands on vehicle authorization start methods.

[0003] Traditional vehicle authorization start methods involve the vehicle's controller sending a request to locate the digital key after the user presses the start button. Based on the digital key's location, the controller returns a response indicating whether a valid digital key is present inside the vehicle (primarily determining if the key is within the authorized start range). If a key is found, the controller sends a start permission request to start the engine; otherwise, the process terminates, and the vehicle does not start. This method has certain drawbacks. In scenarios with severe electromagnetic interference or where the user's digital key (such as a mobile phone) is obstructed (e.g., inside a bag), the ranging signals of BLE (Bluetooth Low Energy) and UWB (Ultra Wide Band) weaken. This can cause the vehicle to misinterpret a mobile phone actually inside the vehicle as being outside the authorized start range. In other words, this method suffers from inaccurate vehicle authorization start due to severe electromagnetic interference or obstructions like the key being inside a bag.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0008] In one embodiment, the method further includes, before controlling the vehicle to start: The cumulative detection time of the digital key associated with the vehicle is determined to be less than or equal to a preset authorization time, wherein the cumulative detection time is the time taken to detect the digital key within the amplified initial startup range.

[0010] In one embodiment, before detecting the vehicle-associated digital key within the amplified initial start range to control the vehicle start in response to a pre-defined authorization condition for an authorized start request for the vehicle meeting, the method further includes: In response to receiving an authorization to start request, the current mode of the vehicle is obtained; When the current mode is the undriven mode, check whether the authorized startup request meets the preset authorized conditions.

[0011] In one embodiment, the vehicle authorized start method further includes: After the authorized start request meets the preset authorized conditions, if the vehicle meets at least one of the first, second, third, and fourth conditions, then the authorized start is terminated by a preset authorized start termination command, wherein: The first condition is that the vehicle starts and enters drive mode; The second condition is that the vehicle's Bluetooth connection status is disconnected; The third condition is that the cumulative detection time of the digital key is greater than the preset authorization time, and the cumulative detection time is the time taken to detect the digital key within the amplified initial startup range; The fourth condition is receiving an authorization cancellation instruction.

[0012] In one embodiment, the vehicle authorized start method further includes: Obtain the authentication data under the authentication request for the vehicle; If the authentication data passes the verification, the authorization launch request is generated.

[0013] In one embodiment, the vehicle authorized start method further includes: A Bluetooth communication connection is established with the digital key based on a preset Bluetooth connection protocol, wherein the Bluetooth communication is used to send the authorized start request to the vehicle.

[0014] In one embodiment, the amplified initial startup range includes at least one of the following ranges: A first extended range is formed by a circle with the vehicle as the center and a first distance as the radius, wherein the first distance is greater than the boundary of the authorized start range and the farthest distance of the vehicle; A second extended range is formed by an ellipse with the vehicle as the center and a second distance as the major radius, wherein the second distance is greater than the boundary of the authorized start range and the farthest distance from the vehicle; A third extended range formed by a polygon centered on the vehicle; the longest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized start range and the vehicle, and / or the shortest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized start range and the vehicle. The fourth extended range is formed by target line segments with the vehicle as the endpoint and the fourth distance as the line segment length; the different directions of the target line segments are different, and the fourth distance is greater than the boundary of the authorized start range and the farthest distance of the vehicle.

[0016] This application also provides a computer-readable storage medium storing a vehicle authorized start method program, wherein when the vehicle authorized start method program is executed by a processor, it implements the steps of the vehicle authorized start method as described above.

[0017] This application provides a vehicle authorized start method. In response to an authorized start request for the vehicle meeting preset authorized conditions, the method detects the vehicle-associated digital key within an expanded initial start range to control vehicle start. The initial start range is determined based on the authorized start range defined by target regulations for digital keys. This vehicle authorized start method, by detecting the vehicle-associated digital key within an expanded initial start range under the premise that the authorized start request meets preset authorized conditions, can be understood as expanding the authorized start range defined by target regulations for digital keys and detecting the vehicle-associated digital key within this expanded initial start range to control vehicle start. This avoids the limitations of BLE (Bluetooth Low Energy) and UWB (Ultra Wide Earth) technologies in scenarios with severe electromagnetic interference or where the user places the digital key (such as a mobile phone) in a bag. The ranging signal of a wideband (UWB) sensor weakens, which may cause the vehicle to misjudge a mobile phone that is actually inside the vehicle as being outside the authorized start range. In other words, this vehicle authorized start method can detect the vehicle-associated digital key within the expanded initial start range, provided that the authorized start request meets the preset authorized conditions, and then control the vehicle to start. That is, it uses a larger range to detect whether there is a digital key, so as to avoid detection errors in scenarios with severe electromagnetic interference or where the user has the digital key (such as a mobile phone) in a bag, thereby improving the accuracy of vehicle authorized start.

[0021] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0022] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0023] With the development of vehicles, digital keys are becoming increasingly common for unlocking and starting vehicles. Digital car keys typically refer to the function of locking, unlocking, and starting a vehicle via user terminals such as smartphones and smartwatches, utilizing technologies such as NFC (Near Field Communication), Bluetooth, or UWB. It is gradually becoming a standard feature in modern smart cars. The implementation principle involves the vehicle-side digital key master module in the vehicle control terminal establishing a Bluetooth connection with the digital key and completing security authentication. Based on the distance measurement capabilities of both parties, BLE and / or UWB distance measurement is activated. The vehicle-side terminal uses the original distance measurement results combined with a positioning algorithm to determine the location of the digital key within the vehicle. Further details can be found in [the following section / reference]. Figure 2 , Figure 2This is a schematic diagram of a vehicle control scenario in the vehicle authorization start method of this application. The area around the vehicle is pre-divided into multiple logical zones, such as a start zone, an approach unlock zone, and a distance lock zone. When the vehicle-side digital key master module determines that the user is approaching the unlock zone with the digital key, it triggers an unlock request to the vehicle domain control module in the vehicle control terminal to achieve seamless unlocking of the vehicle. When the vehicle-side digital key master module determines that the user is approaching the lock zone with the digital key, it triggers a lock request to the vehicle domain control module to achieve seamless locking of the vehicle. For the one-button start function, when the user presses the start button, the vehicle domain control module sends a request to the digital key master module to find the digital key inside the vehicle. The digital key returns a query based on the location result to determine if a valid key is inside the vehicle. If a key is found, the vehicle domain control module sends a start permission request to the vehicle controller to start the engine; if no key is found, the process terminates, and the vehicle will not start. Furthermore, the vehicle-side digital key master module typically defines the activation zone as extending beyond the vehicle's boundaries. For example, anti-theft regulations require that "unlocking the power-operated stop device should ensure the digital key is detected inside the vehicle, or that the driver intentionally triggers the operation within a 6m radius of the vehicle. The distance limit for unlocking the power-operated stop device after detecting the digital key inside the vehicle should be within a 2m radius of the vehicle, meaning the authorized activation range is defined as within 2m." In other words, the defined activation zone for detecting the digital key cannot exceed 2m of the vehicle's perimeter. However, in situations with electromagnetic interference or significant obstruction, such as when the digital key is in a bag, both BLE and UWB ranging signals may weaken or even be lost. This could lead to the in-vehicle device being mistakenly located beyond a 2m radius, resulting in gear shifting failure, i.e., activation authorization failure.

[0024] Therefore, based on the shortcomings of the above vehicle authorization start methods, the vehicle authorization start method of this application is proposed. The solution in this application embodiment is as follows: Under the premise that the authorized start request meets the preset authorized conditions, the vehicle-associated digital key is detected within an expanded initial start range to control vehicle start. This can be understood as expanding the authorized start range defined by the target regulations for digital keys, and detecting the vehicle-associated digital key within this expanded initial start range to control vehicle start. This avoids the problem that BLE (Bluetooth Low Energy) and UWB (Ultra Wide Band) ranging signals weaken in scenarios with severe electromagnetic interference or where the user places the digital key (such as a mobile phone) in a bag, which could lead to the vehicle misjudging a mobile phone actually inside the vehicle as being outside the authorized start range. In other words, this vehicle authorized start method can detect the vehicle-associated digital key within an expanded initial start range to control vehicle start, provided the authorized start request meets the preset authorized conditions. This uses a larger range to detect the presence of a digital key, avoiding detection errors in scenarios with severe electromagnetic interference or where the user places the digital key (such as a mobile phone) in a bag, thereby improving the accuracy of vehicle authorized start.

[0025] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or a device capable of performing the above functions, such as a vehicle control terminal. The following description uses a vehicle control terminal (which includes at least a vehicle body domain control module and a vehicle-side digital key master module) as an example to illustrate this embodiment and the subsequent embodiments.

[0026] Based on this, embodiments of this application provide a vehicle authorized start method, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle authorization start method of this application.

[0027] Reference Figure 1 This application provides a vehicle authorized start method. In a first embodiment of the vehicle authorized start method, the vehicle authorized start method includes: Step S10: In response to the authorized start request for the vehicle meeting the preset authorized conditions, the digital key associated with the vehicle is detected within the enlarged initial start range to control the vehicle start. The initial start range is determined based on the authorized start range for the digital key as defined by the target regulations.

[0028] For example, regarding the existing problem that "in scenarios with severe electromagnetic interference or where the user's digital key (such as a mobile phone) is placed in a bag, the ranging signals of BLE and UWB weaken, causing the vehicle to misjudge a mobile phone actually inside the vehicle as being outside the authorized start range," there are generally two improvement solutions. One is to increase the number of ranging modules on the vehicle's digital key. This method can improve positioning accuracy to some extent and reduce the probability of the above problem occurring, but it increases vehicle costs, and increasing the number of modules increases the difficulty of their placement. The other solution relies on remote authorized start, where the user clicks remote start on a mobile device application. The application sends the request to the vehicle manufacturer's cloud server via the 4G / 5G cellular network, and the cloud server then sends the authorized start request to the vehicle, ultimately starting the vehicle. This solution does not rely on the vehicle's ranging capabilities, but it is limited by the network of the mobile device and the vehicle. Therefore, this solution is ineffective in usage scenarios with poor network signals, such as underground parking garages. Therefore, based on the shortcomings of the above-mentioned improvement schemes, the vehicle authorization start method of this application is further proposed, so as to improve the accuracy of vehicle authorization start without increasing hardware costs and reducing dependence on the network.

[0029] In this embodiment, the vehicle authorization start method is applied to the vehicle, which can be the vehicle's control terminal, body domain controller, or digital key master controller, etc., and is not limited thereto. When the vehicle receives an authorization start request for the vehicle, and after determining that the authorization start request meets the preset authorization conditions, it will detect the vehicle-associated digital key within the amplified initial start range to control the vehicle start. The vehicle-associated digital key can be a digital key with a unique correspondence to the vehicle, or a digital key authenticated on the vehicle. The authorization start request refers to a request issued by the user requiring authorization, which can be in the form of a control signal or electrical level. Meeting the preset authorization conditions generally involves verifying the validity and authenticity of the request from the initiator. When the verification of the validity and authenticity of the request passes, it is determined that the authorization start request meets the preset authorization conditions. Of course, other verification methods can also be used, which will not be described in detail here. The initial start range is determined based on the authorized start range for digital key positioning according to target regulations. These target regulations can be anti-theft regulations, user-defined security range regulations, or regulations defining the effective range for optimal signal transmission. For example, based on target regulations, the initial start range can be defined as within 2m or 4m of the vehicle's boundary, or within 2m of the vehicle's center. An enlarged initial start range refers to expanding the initial start range. When the initial start range is a circular area, the radius can be directly increased; when it is an elliptical area, the major radius can be directly increased. Alternatively, the distance can be specifically extended in a particular direction; these variations will not be elaborated upon here. Furthermore, by expanding the initial start range, the possibility of detection errors can be reduced in scenarios with severe electromagnetic interference or where the user has the digital key (such as a mobile phone) heavily obstructed, thus improving the accuracy of vehicle authorized start.

[0030] In one embodiment, reference may be made to Figure 3 , Figure 3 This is a flowchart illustrating the vehicle authorization start method of this application. When the authorization start request for the vehicle meets the preset authorization conditions, the system begins to detect the vehicle's associated digital key within an expanded initial start range. If the digital key is detected, the system controls the vehicle to start; otherwise, if no digital key is detected, the system prevents the vehicle from starting. Expanding the detection range avoids detection errors caused by obstruction or interference, thus improving the accuracy of vehicle authorization start. It is worth noting that... Figure 3 The digital key example uses a mobile app. For further details, please refer to... Figure 4 , Figure 4This is a schematic diagram of the vehicle authorized start system of this application. The user terminal acts as a communication link between the digital key, the vehicle control terminal, and the cloud. The user terminal and the vehicle control terminal can connect via Bluetooth or UHF, while the cloud connects to both via a network. The user terminal includes at least the vehicle manufacturer's software to implement the vehicle authorized start software, a mobile wallet, and security elements as described in this application. The digital key frame in the user terminal can communicate with the main digital key module via Bluetooth or UHF, while the vehicle network communication module in the vehicle control terminal connects to the vehicle manufacturer's cloud server in the cloud. The vehicle control terminal can control door locks, gear shift, windows, etc. This application mainly uses Bluetooth and UHF to achieve communication between the user terminal and the vehicle control terminal, thus eliminating the need for a cloud network to achieve vehicle authorized start, thereby ensuring the accuracy of vehicle authorized start in the absence of a network.

[0031] This embodiment provides a vehicle authorized start method. In response to an authorized start request for the vehicle meeting preset authorized conditions, the method detects the vehicle-associated digital key within an expanded initial start range to control vehicle start. The initial start range is determined based on the authorized start range defined by target regulations for digital keys. This vehicle authorized start method, by detecting the vehicle-associated digital key within the expanded initial start range under the premise that the authorized start request meets preset authorized conditions, can be understood as expanding the authorized start range defined by target regulations for digital keys and detecting the vehicle-associated digital key within this expanded initial start range to control vehicle start. This avoids the limitations of BLE (Bluetooth Low Energy) and UWB (Ultra Wide Earth) technologies in scenarios with severe electromagnetic interference or where the user places the digital key (such as a mobile phone) in a bag. The ranging signal of a wideband (UWB) sensor weakens, which may cause the vehicle to misjudge a mobile phone that is actually inside the vehicle as being outside the authorized start range. In other words, this vehicle authorized start method can detect the vehicle-associated digital key within the expanded initial start range, provided that the authorized start request meets the preset authorized conditions, and then control the vehicle to start. That is, it uses a larger range to detect whether there is a digital key, so as to avoid detection errors in scenarios with severe electromagnetic interference or where the user has the digital key (such as a mobile phone) in a bag, thereby improving the accuracy of vehicle authorized start.

[0032] Furthermore, based on the first embodiment of this application applied to a vehicle control terminal, a second embodiment of the vehicle authorized start method of this application is proposed. In this embodiment, step S10, which involves detecting the vehicle-associated digital key within the magnified initial start range to control vehicle start, includes: Step S11, in response to detecting the vehicle-associated digital key within the amplified initial start range, control the vehicle to start.

[0033] In this embodiment, once it is determined that the vehicle's authorized start request meets the preset authorization conditions, the system begins searching for a digital key within the expanded initial start range to start the vehicle. If the vehicle-associated digital key is detected within the expanded initial start range, the system responds by controlling the vehicle to start; conversely, if no vehicle-associated digital key is detected within the expanded initial start range, the system notifies the vehicle control terminal to prohibit vehicle start. The entire vehicle start process can be achieved through user-initiated authorized start requests, combined with an expanded detection range to ensure the accuracy of authorized start.

[0034] Furthermore, controlling the vehicle to start also includes: Step S111: Determine that the cumulative detection time of the digital key associated with the vehicle is less than or equal to the preset authorization time. The cumulative detection time is the time taken to detect the digital key within the amplified initial startup range.

[0035] In this embodiment, if the vehicle-associated digital key is detected immediately upon the start of detection within the amplified initial start range, the vehicle will be started directly. The cumulative detection time refers to the time taken to detect the digital key within the amplified initial start range, i.e., the time interval from the start of digital key detection to its detection. Conversely, if the digital key is not detected continuously, the detection range will not be maintained within the amplified initial start range to avoid interference with subsequent starts. For example, assuming the amplified initial start range is 6 meters and no digital key is detected in this instance, if the detection range is continuously set to 6 meters, non-owners or malicious users could start the vehicle within that 6-meter range using conventional methods, resulting in malicious vehicle startup. Therefore, a limit needs to be placed on the duration of digital key detection for the entire vehicle. In other words, a timer is started simultaneously with the digital key detection to expand the initial detection range within the timer's specified time. The digital key is then detected within this expanded initial detection range, provided that the cumulative detection time for the vehicle-associated digital key is less than or equal to a preset authorized time. The cumulative detection time is the time taken to detect the digital key within the expanded initial detection range. If the preset authorized time is exceeded, the detection range reverts to the initial detection range, and the expansion of the initial detection range ceases. For example, refer to... Figure 3After the vehicle's authorized start request meets the preset authorization conditions, a timer is started to activate it. The vehicle's digital key master module receives a gear shifting and key retrieval request from the vehicle's body domain control module subsystem. Normally, the vehicle's digital key master module checks whether a valid key exists within a 2m range inside and outside the vehicle. However, for digital keys in an active authorized start state (i.e., the vehicle authorized start method in the above embodiment), the range can be extended to 6m outside the vehicle, or other extension methods can be used. Within a preset authorization time, the vehicle's digital key master module returns the key retrieval result to the body domain control module. If the body domain control module receives a key retrieval result indicating a key exists, it performs a gear shifting operation, i.e., starts the vehicle. If the body domain control module receives a key retrieval result indicating no key exists, it does not perform a gear shifting operation, i.e., prevents the vehicle from starting. During the authorization startup process using the authorization startup request, once the user successfully authorizes the startup, the vehicle system will activate a timer. During this time period, the detection range of the digital key can be temporarily relaxed from the strictly defined "2 meters inside and outside the vehicle" to "6 meters outside the vehicle". This directly solves the problem of the mobile phone being mistakenly identified as being outside the vehicle due to signal obstruction, thus ensuring the accuracy of vehicle authorization startup. At the same time, the timer mechanism ensures that the privilege escalation is temporary, avoiding long-term security risks.

[0036] In one embodiment, the amplified initial startup range includes at least one of the following ranges: A first extended range is formed by a circle with the vehicle as the center and a first distance as the radius, wherein the first distance is greater than the boundary of the authorized start range and the farthest distance of the vehicle; The second extended range is formed by an ellipse with the vehicle as the center and the second distance as the major radius, where the second distance is greater than the boundary of the authorized start range and the farthest distance from the vehicle. A third extended range consisting of a polygon centered on the vehicle; the longest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized starting range and the vehicle, and / or the shortest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized starting range and the vehicle. The fourth extended range is defined by target line segments with the vehicle as the endpoint and the fourth distance as the line segment length; different target line segments have different directions, and the fourth distance is greater than the boundary of the authorized start range and the farthest distance from the vehicle.

[0037] In this embodiment, the enlarged initial starting range can be a first extended range formed by a circle with the vehicle as the center and a first distance as the radius. The first distance is greater than the boundary of the authorized starting range and the farthest distance from the vehicle. For example, a circle with radius Am can be used as the enlarged initial starting range, where the circle has a radius of A-Bm, where AB is a positive number and A is greater than B. In another embodiment, the enlarged initial starting range can also be an ellipse based on the vehicle's shape. This ellipse forms a second extended range with the vehicle as the center and a second distance as the major radius. The second distance is greater than the boundary of the authorized starting range and the farthest distance from the vehicle. Alternatively, the minor radius can also be greater than the boundary of the authorized starting range and the farthest distance from the vehicle, or only the second distance can be greater than the boundary of the authorized starting range and the farthest distance from the vehicle, while the minor radius is equal to the boundary of the authorized starting range and the farthest distance from the vehicle. In one embodiment, the range can be expanded to an irregular polygon, such as a rectangle. In this case, the third extended range is formed by the rectangle, and the longest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized start range and the vehicle, and / or the shortest distance between the vehicle and the boundary of the polygon is greater than the farthest distance between the boundary of the authorized start range and the vehicle. However, generally, the distance between the vehicle and the boundary of the polygon must be greater than or equal to the farthest distance between the boundary of the authorized start range and the vehicle, and there must be at least one distance between the vehicle and the boundary of the polygon that is greater than the farthest distance between the boundary of the authorized start range and the vehicle. In one embodiment, the range can also be expanded to a fourth extended range formed by target line segments with the vehicle as the endpoint and the fourth distance as the line segment length. For example, a certain area can be expanded to detect whether a digital key exists on the corresponding target line segment. For example, the front and rear areas can be kept at their original ranges, while the seat areas can be expanded to detect whether a digital key exists on the target line segments of the expanded range. The above are four scenarios for the expanded initial start range, mainly expanding the distance by comparing it with the initial start range, thereby expanding the entire range. It is worth noting that the farthest distance between the boundary of the authorized starting range and the vehicle refers to the distance between the boundary of the authorized starting range and the vehicle. Assuming that the authorized starting range is circular, the farthest distance between the boundary of the authorized starting range and the vehicle is the radius of the circle. In this case, the center of gravity or center of the vehicle can be used as the center of the circle, or other definitions can be used, which will not be explained in detail here.

[0038] Furthermore, based on the first and / or second embodiments of this application described above, a third embodiment of the vehicle authorized start method of this application is proposed. In this embodiment, before step S10, in response to the authorized start request for the vehicle meeting preset authorized conditions, before detecting the vehicle-associated digital key within the amplified initial start range to control vehicle start, the method further includes: Step S101: In response to the authorization start request, execute the generation of verification plaintext data based on the authorization start request; Step S102: Obtain the feedback ciphertext data corresponding to the verification plaintext data, and determine the feedback interval of the feedback ciphertext data and the decryption plaintext data; Step S103: If the plaintext data and the decrypted plaintext data match, and the feedback interval is less than or equal to the preset feedback interval, then the authorization start request is determined to meet the preset authorization conditions.

[0039] In this embodiment, upon receiving an authorization start request from a user's terminal based on a digital key, verification plaintext data is generated based on the authorization start request. Verification plaintext data verifies the reasonableness and accuracy of the authorization start request. For example, the verification plaintext data can be a random number in plaintext. After sending the verification plaintext data to the terminal corresponding to the digital key, the terminal returns corresponding ciphertext feedback data, which is then verified. For example, algorithms such as AES_128_CBC are used to decrypt the ciphertext feedback data to obtain decrypted plaintext data. If the verification plaintext data matches the decrypted plaintext data, and the feedback interval is less than or equal to a preset feedback interval, the authorization start request is determined to meet preset authorization conditions. The feedback encrypted data refers to the data obtained by encrypting the verification plaintext data using a relevant encryption algorithm, such as AES_128_CBC. The feedback interval refers to the time interval between sending the verification plaintext data to the terminal corresponding to the digital key and receiving the corresponding feedback encrypted data. This feedback interval design prevents the vehicle from continuously waiting for verification. The preset feedback interval is a user-defined interval. If the verification plaintext data and decrypted plaintext data do not match, or if the feedback interval exceeds the preset feedback interval, the authorization start request is determined to meet the preset authorization conditions, and a verification failure message is returned to the digital key, ending the entire vehicle authorization start process. For example, if the verification plaintext data and decrypted plaintext data are the same, they are considered a match; or if they belong to the same type, they are considered a match. Other custom matching methods are also possible, which will not be detailed here.

[0040] In one embodiment, before detecting the vehicle-associated digital key within the amplified initial start range to control vehicle start in response to a preset authorized start request satisfying authorized conditions, the method further includes: Step S104: In response to receiving the authorized start request, obtain the current mode of the vehicle; Step S105: If the current mode is undriven mode, check whether the authorization startup request meets the preset authorization conditions.

[0041] In this embodiment, after receiving the authorized start request, the vehicle's current mode is also determined. The current mode can be either started or not started. This determination can be based on the vehicle's power-on status or can be made using other methods, which are not limited here. Figure 3 Upon receiving the authorization start request, the vehicle-side digital key master module monitors the vehicle power mode information periodically sent by the body domain control module and determines that the current vehicle power mode is Driving (drive mode). The vehicle-side digital key master module sends a Bluetooth authorization start response to the digital key cmd_RKE_Allow_Resp. The response instruction includes the execution status (Status=0x01 Failure) and the failure error code (Errorcode=0x01 Vehicle is already in Driving mode). After receiving the authorization failure response from the vehicle-side app, the mobile phone interface displays "Authorization failed because the vehicle has already started." Conversely, only when the current mode is in non-drive mode is the authorization start request checked to see if it meets the preset authorization conditions. That is, at this time, the generation of verification plaintext data based on the authorization start request begins. In other words, before step S101, the current mode is checked to determine whether the vehicle authorization start method can be executed normally. Further details regarding the verification process can be found in [reference needed]. Figure 3Before sending the verification plaintext data, it is necessary to first determine that the vehicle is not in Driving mode. In this case, the digital key master module initiates a random number challenge for authorization to start. Authorizing the start when the vehicle is in Driving mode is meaningless. When not in Driving mode, the vehicle-side digital key master module initiates a random number challenge, using a random number to avoid replay attacks between Bluetooth communications (avoiding repeated authorization requests). For example, the random number challenge command includes the generated 8-byte plaintext random number C-Rnd, which is the verification plaintext data. Simultaneously, to avoid continuously waiting to receive encrypted verification information, the vehicle-side digital key master module can start a 3-second timer. The vehicle manufacturer's APP on the related digital key terminal uses the authentication-generated session key, SessionKey, and, for example, based on the AES_128_CBC encryption algorithm, encrypts the random number C-Rnd to obtain the 16-byte ciphertext information En-C-Rnd. The data padding algorithm is the PKCS7 algorithm, and the initialization vector C-IV uses the first 16 bytes of SHA256(C-Rnd). At this point, the ciphertext information En-C-Rnd corresponding to the plaintext random number C-Rnd can be obtained, i.e., the feedback ciphertext data. Due to the 3-second timer setting, there are at least two possible outcomes. One is that the 3-second timer expires, and the vehicle-side digital key master module does not receive the ciphertext response 0 from the digital key random number challenge, or receives it but the verification fails. In this case, the vehicle-side digital key master module sends a Bluetooth authorization start response cmd_RKE_Allow_Resp to the digital key, and the response instruction includes the execution status (Status=0x01 Failure) and the failure error code (Errorcode=0x02 Random number challenge verification failed). The other outcome is that the vehicle-side digital key master module receives the ciphertext of the digital key random number challenge before the 3-second timer expires and the verification passes. Then, after receiving the vehicle-side authorization success response through the vehicle manufacturer's APP, it returns to the mobile phone interface to display "Authorization Successful," and the Bluetooth authorization start indicator light illuminates. Of course, the vehicle can also use relevant algorithms to decrypt the feedback ciphertext data, which will not be described in detail here. The entire authorization verification process avoids replay attacks by using random number challenges, and ensures the security of data exchange by using encrypted data processing.

[0042] In one embodiment, the vehicle authorized start method of this application has at least the following advantages over the methods of adding a ranging module and remote start via the cloud, which can be analyzed based on the following table 1:

[0043] Table 1 Therefore, the vehicle authorization start method proposed in this application cleverly balances cost, reliability, security, and user experience. It does not employ brute force (such as adding hardware) to improve ranging accuracy, nor is it constrained by external network conditions. Instead, through process innovation and software logic optimization, it utilizes existing hardware resources to provide a low-cost, highly reliable, highly secure solution with an excellent user experience, perfectly compensating for the shortcomings of the two existing technical approaches.

[0044] Furthermore, based on the first, second, and / or third embodiments of this application applied to a vehicle control terminal described above, a fourth embodiment of the vehicle authorized start method of this application is proposed. In this embodiment, the vehicle authorized start method further includes: Step S120: After the authorized start request meets the preset authorized conditions, if the vehicle meets at least one of the first, second, third, and fourth conditions, the authorized start is terminated by controlling the vehicle through a preset authorized start termination command, wherein: The first condition is that the vehicle is started and enters drive mode; The second condition is that the vehicle's Bluetooth connection status is disconnected. The third condition is that the cumulative detection time of the digital key is greater than the preset authorization time. The cumulative detection time is the time taken to detect the digital key within the amplified initial startup range. The fourth condition is receiving an authorization cancellation instruction.

[0045] In this embodiment, to achieve complete control over the entire authorized start process, different termination scenarios can be designed. These scenarios include: the vehicle has already been authorized for start; the Bluetooth connection between the digital key and the vehicle is lost; the user actively cancels the authorization; or the preset authorization duration of the authorization timer expires. This forms a secure closed loop. This ensures the controllability of the authorization state, prevents authorization abuse, and allows the system to return to a secure state at any time, greatly enhancing its robustness and security. The preset authorized start termination command is an instruction to the digital key to terminate the authorization. Externally, this can be manifested by generating a voice or text prompt on the digital key while simultaneously controlling the vehicle to terminate the authorized start. For example, "vehicle has been authorized to start" means the vehicle has entered driving mode; "Bluetooth connection between the digital key and the vehicle is disconnected" means the vehicle's Bluetooth connection is disconnected, primarily the connection with the digital key; "user-initiated cancellation" means the user enters or presses a cancellation command on the terminal corresponding to the digital key; "preset authorization duration timeout" means the cumulative detection time of the digital key exceeds the preset authorization duration. The cumulative detection time is the time taken to detect the digital key within the amplified initial start range, meaning the amplified range needs to be reverted to its original range at this point. Furthermore, as... Figure 3 When the vehicle-side digital key master module monitors the vehicle power mode information periodically sent by the body domain control module and determines that the current vehicle power mode is Driving, the vehicle-side digital key master module ends the Bluetooth authorization start timer (i.e., the timer for the preset authorization duration) and sends a notification of Bluetooth authorization start ending to the digital key. Upon receiving the authorization end notification, the vehicle manufacturer's app on the digital key displays "Authorization terminated," and the Bluetooth authorization start indicator light turns gray. Conversely, when the digital key master module detects that the key that activated Bluetooth authorization start has disconnected, the Bluetooth authorization start timer (i.e., the timer for the preset authorization duration) is stopped, the vehicle manufacturer's app on the digital key detects the Bluetooth connection disconnection, the digital key displays "Authorization terminated," and the Bluetooth authorization start indicator light turns gray. Gray; When the user clicks the Bluetooth authorization start button again on the car manufacturer's app for the digital key, the digital key sends an authorization termination request to the vehicle's digital key main module. The digital key main module ends the Bluetooth authorization start timer, which is the timer for the preset authorization duration. The digital key main module sends a notification that the Bluetooth authorization start has ended to the digital key. After receiving the authorization termination notification from the vehicle, the car manufacturer's app for the digital key displays "Authorization terminated" and the Bluetooth authorization start indicator light turns gray; When the digital key main module detects that the timer has timed out, that is, the preset authorization duration has been exceeded, it sends a notification that the Bluetooth authorization start has ended to the digital key. After receiving the authorization termination notification from the vehicle, the car manufacturer's app for the digital key displays "Authorization terminated" and the Bluetooth authorization start indicator light turns gray.

[0046] Furthermore, based on the first, second, third, and / or fourth embodiments of this application applied to a vehicle control terminal described above, a fifth embodiment of the vehicle authorized start method of this application is proposed. In this embodiment, the vehicle authorized start method further includes: Step a, obtain the authentication data under the authentication request for the vehicle; Step b: If the authentication data verification result is successful, generate an authorization start request.

[0047] In this embodiment, when a user inputs an authorization command via the digital key, such as clicking the authorization start icon displayed on the digital key, authentication data is obtained under the vehicle authentication request. This forcibly invokes the digital key's security authentication (such as fingerprint, face, or password), acquiring authentication information such as facial features or password as authentication data. If the authentication data verification result is successful, an authorization start request is generated. This ensures that the start operation is consciously initiated by the authorized vehicle owner, thus meeting the regulatory requirement of "consciously triggered operation." This allows the system to legally and temporarily expand the key's effective scope while maintaining security compliance. The authentication request refers to the request information generated based on the user's input of the authorization command. This information can directly access the camera or keyboard on the digital key, allowing the user to input authentication data based on the authentication request, ensuring the accuracy and security of the generated authorization start request. Further details can be found in... Figure 3 Taking a mobile phone as a digital key as an example, after the user enters an authorization start request on the digital key, the car manufacturer's app calls the API (Application Programming Interface) provided by the mobile phone's operating system to trigger system-level authentication (such as password, fingerprint, face, etc.). After the user completes the authentication and succeeds, a Bluetooth authorization start request cmd_RKE_Allow_Req is sent to the main module of the vehicle's digital key. The request instruction includes: authorization time Time_allow_start (0x01: 3min; 0x02: 5min; 0x03: 10min). The authorization time refers to the time during which the detection range is expanded. By setting the authorization time, the detection effect can be guaranteed on the one hand, avoiding the influence of electromagnetic interference and obstruction, and on the other hand, the security problems caused by continuously expanding the detection range can be avoided.

[0048] For example, once the authentication data verification result is confirmed as successful, the process described above for determining whether the authorization start request meets the preset authorization conditions is executed. If the authorization start request meets the preset authorization conditions, the vehicle-associated digital key is detected within the expanded initial start range to control vehicle start. In one embodiment, once the authentication data verification result is confirmed as successful and the authorization start request meets the preset authorization conditions, the authorization termination process described above can also be executed.

[0049] Furthermore, based on the first, second, third, fourth, and / or fifth embodiments of this application applied to a vehicle control terminal, a sixth embodiment of the vehicle authorized start method of this application is proposed. In this embodiment, the vehicle authorized start method further includes: Step c: Establish a Bluetooth communication connection with the digital key based on the preset Bluetooth connection protocol, wherein the Bluetooth communication is used to send an authorization start request to the vehicle.

[0050] In this embodiment, Bluetooth communication needs to be established between the vehicle and the digital key. This can be achieved by pre-establishing a Bluetooth communication connection between the vehicle and the digital key using a communication protocol based on an existing secure Bluetooth connection, such as cmd_RKE_Allow_Req, cmd_RKE_Allow_Chlg_Req, or cmd_RKE_Allow_Resp. This allows the user to proactively initiate a high-priority activation authorization via the digital key. This request interacts directly with the vehicle through the Bluetooth channel, completely bypassing the reliance on the cellular network. When the user approaches the vehicle with their mobile phone (one type of digital key), the vehicle-side digital key master module in the vehicle control terminal establishes a Bluetooth connection with the digital key, completes service authentication, and generates a SessionKey. When a user needs to authorize vehicle startup, they manually open the car manufacturer's app on their phone, click the Bluetooth authorization start button, and an authorization start request is generated. This request is then sent to the vehicle via Bluetooth. The system can also send back plaintext verification data to determine whether the user's authorization request is valid, i.e., whether the authorization start request meets preset authorization conditions. This Bluetooth-based authorization start request solves the startup problem in scenarios without a network signal, thus improving the functionality of authorized start. Furthermore, Bluetooth communication can be used to verify the authorization start request, ensuring its security.

[0051] For example, after a Bluetooth connection is established between the vehicle and the digital key, the process described above for determining whether the authorized start request meets the preset authorized conditions is executed. If the authorized start request meets the preset authorized conditions, the vehicle-associated digital key is detected within the expanded initial start range to control the vehicle start. In one embodiment, after a Bluetooth connection is established between the vehicle and the digital key and the authentication data verification result is confirmed as successful, the process described above for determining whether the authorized start request meets the preset authorized conditions is executed. If the authorized start request meets the preset authorized conditions, the vehicle-associated digital key is detected within the expanded initial start range to control the vehicle start. In one embodiment, after a Bluetooth connection is established between the vehicle and the digital key and the authentication data verification result is confirmed as successful, the authorization termination process described above can also be executed.

[0052] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the vehicle authorization starting method of this application. Any simple modifications based on this technical concept are within the protection scope of this application.

[0053] This application also provides a vehicle authorized start device, referring to...
