Description

Technical Field

[0001] The invention belongs to the technical field of bicycle intelligent unlocking, and in particular relates to a vehicle unlocking method and device based on side support sensing and Bluetooth security authentication. Background Art

[0002] With the widespread application of intelligent technology in the field of electric bicycles, intelligent unlocking systems have gradually replaced traditional mechanical locks and have become a key technology to improve vehicle safety and user convenience; however, most of the intelligent unlocking systems on the market still have certain technical shortcomings, especially in terms of physical state monitoring, safety and user experience, which urgently need further improvement and optimization.

[0003] First of all, the existing intelligent unlocking system lacks real-time monitoring of the physical state of the electric bicycle side stand. As an important safety component of the electric bicycle, the state of the side stand directly affects the riding safety. If the side stand is not fully retracted or not properly fixed, the electric bicycle may lose balance, tilt or fall during riding, thereby causing a safety accident. However, the existing unlocking system fails to effectively integrate physical sensors to monitor the state of the side stand, resulting in the system still triggering unlocking and starting the vehicle when the side stand is in an unsafe state. In this way, the safety of riding is not fully considered, and there is a great potential risk.

[0004] Secondly, existing smart unlocking systems usually require users to perform complex operations, such as entering a PIN code, pairing Bluetooth, or relying on other identity authentication methods (such as scanning a code and relying on the network to unlock). These manual operations not only increase the user's usage burden, but also make the unlocking process cumbersome and inconvenient. For users who frequently use electric bicycles, the first time they unlock, they need to manually enter a password or pair Bluetooth, which cannot meet the user's demand for convenience.

[0005] Furthermore, the existing smart unlocking system relies on simple Bluetooth pairing for identity authentication, which poses a security risk. In addition, the PIN code used for pairing is relatively simple and lacks sufficient robustness, making it vulnerable to brute force cracking or theft attacks, resulting in low security.

[0006] In summary, the existing intelligent unlocking systems have defects and shortcomings to varying degrees in terms of physical state monitoring, ease of operation and safety. Therefore, how to provide a vehicle unlocking method that is easy to operate, highly secure and supports side support detection has become a problem that needs to be solved urgently. Summary of the invention

[0007] The purpose of the present invention is to provide a vehicle unlocking method and device based on side stand sensing and Bluetooth security authentication, so as to solve the problems of low operating convenience, poor security and potential risks in riding caused by the absence of side stand status detection in the prior art.

[0018] Through the above design, when the present invention unlocks the vehicle, it is only necessary to verify the PIN code when connecting for the first time, and use the self-negotiation mechanism to perform Bluetooth connection, that is, the vehicle generates a first Bluetooth PIN code, and the user terminal generates a second Bluetooth PIN code and sends it to the vehicle, and then the vehicle establishes a Bluetooth connection between the two when it determines that the two are the same; in this way, the entire Bluetooth connection process does not require the user to manually enter the PIN code and manually pair, and after connecting once, the vehicle will automatically recognize it without re-pairing, thereby greatly improving the convenience of use; at the same time, when the Bluetooth connection is made for the first time, the MAC address and current timestamp of the device are introduced, so that the generated PIN code is closely related to the device and time, ensuring the uniqueness and security of each connection; in addition, after the Bluetooth connection, the state of the side stand will also be detected, and the unlocking operation will be performed only when it is determined that it is in a fully retracted state; based on this, the problem of potential riding risks caused by the side stand not being retracted or not being fully retracted is avoided; therefore, the present invention not only improves the safety of the unlocking process and the safety of riding of the electric bicycle, but also simplifies the user operation, thereby ensuring that the user can enjoy a safe and convenient riding experience under any circumstances.

It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0061] It should be understood that although the terms first, second, etc. may be used herein to describe various units, these units should not be limited by these terms. These terms are only used to distinguish one unit from another unit. For example, a first unit can be referred to as a second unit, and similarly, a second unit can be referred to as a first unit without departing from the scope of the exemplary embodiments of the present invention.

For example, A / and B can represent two situations: A exists alone, and A and B exist alone. In addition, the character " / " that may appear in this article generally indicates that the previous and next associated objects are in an "or" relationship.

[0063] Example:

[0064] See also Figure 1As shown, the vehicle unlocking method based on side support sensing and Bluetooth security authentication provided by the present embodiment only needs to perform Bluetooth identity authentication when the user connects for the first time, and uses the self-negotiation mechanism to complete the entire Bluetooth pairing process; in this way, the user does not need to manually enter the PIN code and manually pair, and after connecting once, the vehicle will automatically recognize it without the need for re-pairing; therefore, the convenience of use is greatly improved; at the same time, in the Bluetooth authentication process, the MAC mask of the device and the current timestamp of the device are combined to generate a PIN code, so that the generated PIN code is related to the device and time, which enhances the unpredictability of the PIN code, thereby improving the PIN code security; in addition, after the Bluetooth connection is successful, the state of the side stand will be detected in real time, and the unlocking mechanism will be triggered only when the side stand is fully retracted. Based on this, the disadvantage of traditional technology that the electric bicycle can still be unlocked in an unsafe state is avoided; therefore, the method not only improves the safety of the unlocking process of the electric bicycle and the safety of riding, but also simplifies the user operation, thereby being very suitable for large-scale application and promotion; among them, for example, the method can be but not limited to running on the vehicle equipment side. It can be understood that the aforementioned execution subject does not constitute a limitation on the embodiments of the present application. Accordingly, the operation steps of the method can be but not limited to the following steps S1 to S7.

[0065] S1. After receiving the Bluetooth connection request sent by the user terminal, it is determined whether the user terminal corresponds to the user for the first time connecting to the user; in the specific implementation, see Figure 2 As shown in FIG. 1 , when a user needs to use an electric bicycle (or a common shared bicycle), the user first turns on Bluetooth and then sends a Bluetooth connection request to the vehicle device (i.e. Figure 2 The Bluetooth connection request includes a unique identification of the user terminal. At this time, after receiving the Bluetooth connection request from the user terminal, the vehicle equipment can determine whether the user is a first-time connecting user based on the unique identification (i.e., matching the unique identification in its historical connection user database. If the match is successful, it is determined to be a non-first-time user, otherwise, it is determined to be a first-time connecting user). In this way, it can be decided whether to enter the Bluetooth authentication process or directly establish a Bluetooth connection based on the judgment result; wherein, according to the judgment result in step S1, the different operation processes executed can be but are not limited to those shown in the following step S2.

[0066] S2. If yes, then obtain the current time and the MAC mask of the vehicle, and generate a first Bluetooth PIN code based on the current time and the MAC mask, otherwise, directly establish a Bluetooth connection with the user terminal; in this embodiment, if the user is not a first-time connecting user, then the Bluetooth connection can be directly performed, that is, the following step S5 is executed, otherwise, it is necessary to enter the Bluetooth authentication verification process, wherein, in this embodiment, the current time and the MAC mask (i.e., MAC address) of the vehicle are first obtained, and then, based on this, the first Bluetooth PIN code is generated, and at the same time, the MAC mask is also sent to the user terminal, so that The user terminal generates a second Bluetooth PIN code according to the received MAC mask and the sending time of the Bluetooth connection request (due to the short distance, the difference between the sending and receiving time of the Bluetooth sending request is negligible. Therefore, the time value can be taken in minutes. For example, the sending time is 1:20:04 on December 10, 2024, and the receiving time is 1:20:05 on December 10, 2024, then the time values ​​of both are 1:20 on December 10, 2024), and sends it to the vehicle equipment. In this way, the vehicle equipment can complete the Bluetooth authentication verification by comparing the two Bluetooth PIN codes.

[0067] Optional, see Figure 3 As shown, one of the methods for generating the following public first Bluetooth PIN code may be, but is not limited to, as shown in the following steps S21 to S24.

[0068] S21. Generate a first string based on the MAC mask, and generate a second string based on the current time; in a specific implementation, a number of numbers are extracted from the MAC mask, and the extracted numbers are subjected to binary conversion processing, so as to obtain the first string after the binary conversion processing; similarly, the second string is subjected to binary conversion processing, so as to obtain the second string after the binary conversion processing.

[0069] Further, for example, but not limited to, the last six digits in the MAC mask are extracted, and the extracted last six digits are converted into a binary string, thereby obtaining the first string.

[0070] After obtaining the first character string and the second character string, a first PIN parameter code may be generated based on the first character string and the second character string. The process may be, but is not limited to, as shown in the following step S22.

[0071] S22. Generate a first PIN parameter code using the first character string and the second character string. In a specific application, for example, but not limited to, an XOR operation may be performed on the first character string and the second character string, so that after the XOR operation, the first PIN parameter code is obtained. Then, the second PIN parameter code may be constructed with the help of the first PIN parameter code, and the process is shown in the following step S23.

[0072] S23. Construct a second PIN parameter code according to the first PIN parameter code; in this embodiment, for example, but not limited to, a hash algorithm can be used to perform a hash operation on the first PIN parameter code, so as to obtain the second PIN parameter code after the hash operation; wherein, for example, the hash algorithm can include but is not limited to a SHA-256 hash algorithm; in this case, the SHA-256 hash algorithm is used to convert the first PIN parameter code into a hexadecimal hash value of a fixed length, so as to serve as the second PIN parameter code.

[0073] After the second PIN parameter code is generated, the first Bluetooth PIN code may be generated based on it, and the process may be but not limited to the following step S24.

[0074] S24. Generate the first Bluetooth PIN code based on the second PIN parameter code; in specific implementation, for example, but not limited to, first convert the second PIN parameter code into an integer to obtain a PIN integer code, that is, convert the hexadecimal second PIN parameter code into a decimal integer; then, extract a number of PIN digits from the PIN integer code, and use the extracted PIN digits as the first Bluetooth PIN code; optionally, for example, but not limited to, extract the last six PIN digits from the PIN integer code as the first Bluetooth PIN code; of course, the specific extracted digits can be selected according to actual use, and are not limited to the aforementioned examples.

[0075] In this way, through the aforementioned steps S21 to S24, this embodiment generates a PIN code by introducing the MAC mask and timestamp of the device and combining the XOR operation with the hash algorithm, thereby ensuring the high randomness and security of the PIN code; based on this, it can be guaranteed that each time the device is connected, the generated PIN code is unique and closely related to the device and time, based on this, the security risks that may exist in traditional static passwords are prevented; in addition, the PIN code pairing process adopts an automatic negotiation mode, so that the user does not need to manually enter any password, thereby simplifying the usage process and improving the user experience.

[0076] After the first Bluetooth PIN code is generated, the second Bluetooth PIN code sent by the user terminal can be received so as to complete the Bluetooth authentication by comparing the two. The receiving process of the second Bluetooth PIN code is shown in the following step S3.

[0077] S3. Receive a second Bluetooth PIN code sent by the user terminal, wherein the second Bluetooth PIN code is generated by the user terminal after sending a Bluetooth connection request, by receiving the MAC mask of the vehicle, and based on the MAC mask of the vehicle and the current time; in this embodiment, the generation process of the second Bluetooth PIN code can refer to the aforementioned first Bluetooth PIN code, and its principle will not be repeated here.

[0078] After receiving the second Bluetooth PIN code, the PIN code can be compared, and the process is shown in the following step S4.

[0079] S4. Determine whether the first Bluetooth PIN code and the second Bluetooth PIN code are the same; in this embodiment, if the two are the same, then Bluetooth authentication can be performed, and then the following step S5 is performed, that is, the vehicle device can establish a connection with the user terminal (that is, the Bluetooth of the user terminal is connected to the ECU in the vehicle device, and the Bluetooth is integrated in the ECU); otherwise, the Bluetooth connection is not allowed to be established, and the Bluetooth authentication process can be re-performed, such as Figure 2 shown.

[0080] S5. If yes, establish a Bluetooth connection with the user terminal.

[0081] After establishing a Bluetooth connection with the user terminal, this embodiment also needs to perform real-time detection of the side support status so as to determine whether the unlocking operation can be performed based on the side support status; wherein, the side support status detection process is shown in the following step S6.

[0082] S6. Obtain the state of the vehicle's side stand, and determine whether the side stand is in a fully retracted state; in a specific implementation, for example, a Hall sensor is provided on the vehicle's side stand, and a magnet is provided on the vehicle at a position corresponding to the side stand. Therefore, by receiving the detection signal sent by the Hall sensor, the state of the vehicle's side stand can be determined according to the detection signal; such as a fully retracted state, an incompletely retracted state, or a not retracted state, etc.; of course, a magnet can also be installed on the side stand, and a Hall sensor can be installed at a position corresponding to the vehicle body. The installation form can be specifically set according to actual use, and is not limited to the aforementioned example.

[0083] Specifically, when a magnet approaches the Hall sensor, the sensor detects the change in the magnetic field and generates a voltage signal, and through this voltage signal, the state of the side support can be detected.

[0084] Among them, see Figure 4As shown, when the vehicle equipment (that is, the MCU module in the vehicle equipment) determines that the unlocking conditions are met, that is, the Bluetooth connection is successful and the side support is in a fully retracted state, the unlocking operation can be performed, that is, the following step S7 is executed, otherwise, the unlocking operation is interrupted; optionally, the unlocking process is shown in the following step S7.

[0085] S7. If yes, open the electric door lock of the vehicle to unlock the vehicle; in this embodiment, an unlocking signal is first generated; then, the unlocking signal is sent to the vehicle lock controller, so that the vehicle lock controller opens the electric door lock of the vehicle after receiving the unlocking signal, thereby unlocking the vehicle, that is, the power is turned on and the electric door lock is opened.

[0086] Therefore, through the vehicle unlocking method based on side stand sensing and Bluetooth security authentication described in detail in the aforementioned steps S1 to S7, the present invention only needs to perform Bluetooth identity authentication when the user connects for the first time, and uses the self-negotiation mechanism to complete the entire Bluetooth pairing process; in this way, the user does not need to manually enter the PIN code and manually pair, and after connecting once, the vehicle will automatically recognize it without the need for re-pairing; therefore, the convenience of use is greatly improved; at the same time, in the Bluetooth authentication process, the MAC mask of the device and the current timestamp of the device are combined to generate a PIN code, so that the generated PIN code is related to the device and time, thereby enhancing the unpredictability of the PIN code and thus improving the security of the PIN code; in addition, after the Bluetooth connection is successful, the side stand status will be detected in real time, and the unlocking mechanism will be triggered only when the side stand is fully retracted. Based on this, the disadvantage that traditional technology can still unlock the electric bicycle in an unsafe state is avoided; therefore, the present invention not only improves the safety of the unlocking process and the safety of riding of the electric bicycle, but also simplifies user operations, thereby being very suitable for large-scale application and promotion.

[0090] The Bluetooth module is used to receive a second Bluetooth PIN code sent by a user terminal, wherein the second Bluetooth PIN code is generated by the user terminal after sending a Bluetooth connection request, by receiving a MAC mask of the vehicle, and based on the MAC mask of the vehicle and the current time.
