Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a fingerprint type disc brake lock control system and a control method thereof. Background Art

[0002] With the rapid development of the electric bicycle and electric motorcycle markets, consumers are increasingly demanding safety from electric vehicles. In order to improve the anti-theft performance of vehicles, more and more electric vehicles are equipped with intelligent locking systems to prevent theft or unauthorized use. In particular, disc brake locks, as a common physical lock, are widely used in the brake system of electric vehicles due to their simple structure and high effectiveness. However, traditional disc brake lock systems usually can only rely on manual operation for locking and unlocking, which cannot meet the growing demand for safety, convenience and intelligent management of electric vehicles. Therefore, a new control system that combines intelligent control and physical locking technology has become a major demand direction in the electric vehicle industry.

[0003] At present, the control technology of electric vehicle locks is mostly based on traditional mechanical locking methods or simple electronic lock control methods. Existing locks are usually controlled by password input, remote control or Bluetooth connection. Although these methods have certain security, they have many disadvantages. First of all, most of these locking methods rely on a single input method, such as a password or remote control, which leads to limitations in user experience. For example, the password method is vulnerable to the risk of being peeped or forgotten by others, and the remote control may fail due to battery exhaustion or loss. Secondly, the traditional lock control method lacks intelligent safety protection measures, cannot monitor the environmental status of the vehicle in real time, and is prone to being unable to respond in time when abnormalities occur in the external environment, resulting in an increased risk of electric vehicle theft.

[0004] In view of this, it is necessary to improve the vehicle lock control technology in the prior art to solve the technical problems of lack of intelligent unlocking method and application user experience. Summary of the invention

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] Embodiment 1: Combination Figure 5 and Figure 6 As shown, an embodiment of the present invention provides a control method of a fingerprint disc brake lock control system, comprising: S1, when the electric vehicle is powered on, the vehicle system is started, and the user inputs fingerprint information through the fingerprint recognition module 10 on the front of the vehicle. After receiving the fingerprint information, the vehicle system determines whether the fingerprint is a preset legal fingerprint; The system starts and waits for user operation. At this time, the vehicle is in a locked state, and the disc brake lock 21 is in a locked state. The user inputs fingerprint information through the fingerprint recognition module 10 on the front of the vehicle. After receiving the fingerprint information, the system first determines whether the fingerprint is a legal fingerprint preset by the owner.

[0024] S2, if the fingerprint verification is successful, the vehicle system further confirms the type of permission for the user to start the vehicle based on the identity of the vehicle owner. The permission type is divided into normal mode or guest mode; At this point, the vehicle can enter normal mode or guest mode according to the owner's settings. In normal mode, the vehicle is unlocked and allowed to start; in guest mode, the vehicle allows specific functions to be enabled, but in a restricted security state.

[0025] S3, after the identity verification is successful, the unlocking procedure of the vehicle's disc brake lock 21 is started, the electronic control component 211 drives the telescopic rod 212 to release the lock with the lock disc 22, and at the same time, the vehicle's environmental sensor starts to monitor the surrounding environment information.

[0026] S4, after starting the vehicle and entering the riding mode, the vehicle system will continuously monitor the vehicle status and surrounding environment information. If abnormal information is detected, the disc brake lock 21 unlocking program enters the pre-locking state. At this time, the user enters the matching fingerprint information and enters the disc brake lock 21 locking program. The disc brake lock 21 will lock the lock plate 22; When the disc brake lock 21 lock program is entered, the disc brake lock 21 and the lock plate 22 will be locked to form a stable triangular deadlock structure to prevent the vehicle from continuing to run.

[0027] S5, if the user decides to use the vehicle again and exits the locked state, the vehicle system will automatically prompt the user and perform fingerprint unlocking again.

[0028] The working principle of the present invention is as follows: first, after the electric vehicle is powered on, the user inputs the fingerprint information through the fingerprint recognition module 10 on the front of the vehicle, and the system determines whether the fingerprint is legal; after successful verification, the system confirms the type of permission to start the vehicle according to the identity of the owner, which is divided into normal mode or visitor mode. After successful identity verification, the vehicle system starts the disc brake lock 21 unlocking program, the electronic control component 211 drives the telescopic rod 212 to unlock the lock disk 22, and the vehicle environment sensor starts to monitor the surrounding environment information; then, when the vehicle enters the riding mode, the vehicle system continuously monitors the vehicle status and the surrounding environment. If an abnormality is detected, the disc brake lock 21 unlocking program enters the pre-locking state, and the user can enter the locking program by matching the fingerprint information to ensure that the vehicle is protected in time. If the user decides to use the vehicle again and exits the locked state, the vehicle system will automatically prompt the user and perform fingerprint unlocking again. The whole process ensures that the vehicle is always in a safe and controllable state through intelligent verification and environmental monitoring; this solution provides a full range of protection measures by combining fingerprint recognition with the physical locking mechanism of the disc brake lock 21, effectively combining intelligent control with physical locking, and significantly improving the safety and user experience of the electric vehicle.

[0029] In this embodiment, it is specifically explained that step S1 specifically includes: S11, when the electric vehicle is powered on, the vehicle system automatically starts and initializes, and supplies power to the vehicle hardware and the fingerprint recognition module 10 through the power control module; Initialization includes a self-checking procedure to ensure that each module of the vehicle system functions normally. The vehicle system supplies power to the vehicle hardware and the fingerprint recognition module 10 through the power control module to ensure the stable operation of the system.

[0030] After the vehicle system is initialized, the fingerprint recognition module 10 at the front of the vehicle is activated. The fingerprint recognition module 10 uses optical recognition technology and is equipped with a high-resolution fingerprint scanner and a high-definition sensor to accurately capture the detailed information of the user's fingerprint.

[0031] S12, the user places a finger on the fingerprint recognition module 10 on the front of the vehicle, and the module starts to scan and capture the fingerprint image, and the vehicle system automatically adjusts the sensitivity and exposure time of the fingerprint sensor; To adapt to different ambient lighting conditions, such as fingerprint recognition at night or under strong light. At the same time, the system will determine whether the fingerprint is placed in place. If the fingerprint position is incorrect, the system will prompt the user to readjust the fingerprint position through voice prompts or display screen.

[0032] S13, after the fingerprint image is collected, the vehicle computer system uses an embedded processor to perform feature extraction processing on the collected fingerprint image to extract key feature information of the unique lines, bending points, and endpoints of the fingerprint; The fingerprint image is matched and calculated by the algorithm. To ensure high accuracy of fingerprint recognition, the system uses an improved fingerprint matching algorithm based on deep learning technology, which can handle subtle differences in fingerprint images and avoid recognition errors caused by factors such as wet fingers and worn fingerprints.

[0033] S14, the vehicle system compares the extracted key feature information with the preset legal fingerprint library stored in the vehicle database; determines whether there is a legal fingerprint that matches the collected fingerprint information. If the match is successful, the identity authentication step continues; if the match fails, the vehicle system prompts the user to re-enter the fingerprint, or provides an alternative unlocking method.

[0034] The preset legal fingerprint database stores the fingerprint information of the car owner and authorized visitors, and each user's fingerprint information is encrypted to ensure data security. The fingerprint matching process uses a double encryption algorithm to improve identification security and prevent illegal cracking.

[0035] The system determines whether there is a legitimate fingerprint that matches the collected fingerprint information. If the match is successful, the system continues to perform the subsequent identity verification steps (i.e. step S2). If the match fails, the vehicle system will prompt the user to re-enter the fingerprint, or provide an alternative unlocking method, such as secondary verification through password input or smartphone Bluetooth connection.

[0036] During the fingerprint recognition and verification process, the vehicle system will monitor the working status of the fingerprint module in real time. If a sensor failure or abnormality is detected (such as recognition module failure, low sensor power, etc.), the system will immediately enable the backup verification mechanism and notify the user to check the system status through the on-board display or voice.

[0037] In this embodiment, it is specifically described that step S3 specifically includes: S301, after the electric vehicle is successfully started and enters the riding mode, the vehicle system monitors the vehicle status and surrounding environment information through the vehicle's built-in sensor system; After the electric vehicle successfully starts the vehicle and enters the riding mode, the vehicle system monitors the vehicle status and surrounding environment information through the vehicle's built-in sensor system; at this time, the vehicle system will connect to multiple sensors, including accelerometers, battery management systems, temperature sensors, visual detection modules, etc., through these sensors to collect vehicle status data in real time to ensure that the vehicle is always in a safe and stable operating environment.

[0038] S302, the vehicle system monitors the acceleration information of the electric vehicle through a built-in accelerometer, and determines whether the vehicle complies with the normal driving mode based on the acceleration information; The acceleration data will be fed back to the vehicle system in real time to help determine whether there is abnormal acceleration or deceleration behavior, such as sudden emergency braking or excessive acceleration, and provide users with timely safety tips.

[0039] S303, the vehicle system monitors the battery power in real time through the battery management system to determine whether the battery power is within a safe range; if the battery power is low, the vehicle system will prompt through voice prompts or display screens to avoid accidental shutdowns due to low battery power.

[0040] S304, the vehicle system monitors the temperature status of the motor and battery through temperature sensors to ensure that the temperature does not exceed the preset safety threshold; if an excessively high temperature is detected, the system will activate an automatic cooling mechanism and remind the user to check the vehicle to avoid affecting the performance of the battery or motor due to excessive temperature and ensure safe operation of the vehicle.

[0041] S305, the vehicle system monitors the surrounding environment information in real time through the visual monitoring module, and the environmental information includes the distance of obstacles and road conditions. It helps the vehicle system to identify whether there are potential dangers ahead and provide prompts to the driver to avoid obstacles in time to ensure riding safety.

[0042] S306, when the vehicle system detects that the vehicle speed is abnormal, it will issue an alarm according to the preset speed threshold, reminding the user to slow down, and automatically enter the pre-lock state; at this time, the system will automatically enter the pre-lock state to prevent accidental speed loss and protect the safety of the owner. In the pre-lock state, the vehicle's power system will be automatically limited to avoid unnecessary acceleration or driving.

[0043] S307, when the vehicle system detects that the signal of the disc brake lock 21 is abnormal, the vehicle system will immediately enter the pre-locking mode and perform an emergency test on the brake system; by transmitting the data of the brake system back, the vehicle system will confirm whether the brake can work effectively and notify the user to perform a manual check; by monitoring the data of the brake system back, the system can determine whether the brake can work normally. If the system finds that the brake is abnormal, it will notify the user to perform a manual check to ensure the safety of the brake system and prevent safety accidents caused by brake failure.

[0044] S308: When the vehicle tilts or collides unexpectedly, the vehicle system will automatically determine and enter a pre-locking state to prevent the vehicle from continuing to slide or starting by mistake; Tilting or collision may affect the stability of the vehicle. Therefore, the system uses acceleration sensors, collision sensors, etc. to determine whether the vehicle is in an abnormal state and locks the vehicle in time to prevent further damage or danger.

[0045] S309: When the system detects a rapidly approaching obstacle in the environmental information (such as a vehicle in front, a pedestrian, or other object), the vehicle system will automatically initiate a warning and start the pre-locking state.

[0046] S310, when entering the pre-locking state, the vehicle system receives the fingerprint information input by the user through the fingerprint recognition module 10 on the front of the vehicle, and compares it with the legal fingerprint information in the owner's database; if the comparison is successful, the vehicle system confirms the user's identity and proceeds to the next step; if the fingerprint verification fails, the system will prompt the user to re-enter through the vehicle display or voice to ensure that only authorized users can unlock and start the vehicle.

[0047] S311, after the fingerprint verification is successful, the vehicle system sends a locking command through the electronic control system to start the disc brake lock 21 locking program, and the telescopic rod 212 of the wheel hub brake module 20 will automatically move, mechanically dock with the disc brake lock 21 and complete the locking.

[0048] S312, after the locking process is completed, the vehicle system will confirm that the current vehicle is in a locked state through the vehicle display or voice. After the locking is completed, the system will continue to monitor the vehicle status to prevent the locking state from being released due to external force or the vehicle from being started by mistake.

[0049] S313, after locking, the vehicle system will record the detailed data of the locking operation, including time, user identity and environment information. This data will be saved in the log of the vehicle system, and the user can view the historical records through the vehicle system.

[0050] In this embodiment, it is specifically described that step S5 specifically includes: S51, if the user decides to use the vehicle again and exit the locked state, the vehicle system determines whether the vehicle has entered the parking state by monitoring the vehicle speed, braking state and stationary state data, and automatically prompts the user to unlock the vehicle with fingerprint; The car system will first check the vehicle's speed sensor to ensure that the vehicle has come to a complete stop. Then, the system will confirm the brake status to determine whether the brakes are fully activated to ensure that the vehicle is stationary. When the car system confirms that these conditions meet the parking state, the system will automatically prompt the user to unlock and prompt the user to perform the fingerprint unlocking operation through the in-vehicle display or voice.

[0051] S52, after confirming that the vehicle has stopped, the vehicle system triggers the fingerprint unlocking program and inputs the legal fingerprint information through the fingerprint recognition module 10 at the front of the vehicle for identity authentication; After confirming that the vehicle has stopped, the vehicle system triggers the fingerprint unlocking program and inputs legal fingerprint information through the fingerprint recognition module 10 on the front of the vehicle for identity verification; once the vehicle system confirms that the vehicle is parked, it activates the fingerprint recognition module 10. The user needs to place his finger on the fingerprint recognition module 10, and the system analyzes and processes the collected fingerprint image. The system will ensure that the fingerprint image quality is clear and has no noise, and ensure that it can be effectively recognized under various environmental conditions. The user needs to enter legal fingerprint information.

[0052] S53, after the fingerprint verification is successful, the vehicle system compares the user identity through double encryption. If the verification is successful, the system executes the disc brake lock 21 unlocking procedure to release the connection between the disc brake lock 21 and the lock plate 22; After the fingerprint verification is successful, the vehicle system compares the user identity through double encryption. If the verification is successful, the system executes the disc brake lock 21 unlocking procedure to release the connection between the disc brake lock 21 and the lock plate 22; when the fingerprint information matches the fingerprint information of the owner or the authorized user, the system further verifies the legitimacy of the identity through the double encryption algorithm to ensure that there is no illegal fingerprint input. After the verification is successful, the vehicle system will issue a command to drive the electronic control component 211 to operate the telescopic rod 212, release the mechanical connection between the disc brake lock 21 and the lock plate 22, and complete the unlocking operation.

[0053] S54, after unlocking is completed, the vehicle system confirms that the vehicle has been successfully unlocked through the display screen or voice, continues to monitor the vehicle status and surrounding environment, and starts the vehicle.

[0054] After unlocking is completed, the vehicle system confirms that the vehicle has been successfully unlocked through the display or voice, and continues to monitor the vehicle status and surrounding environment, and starts the vehicle; After unlocking is completed, the vehicle system will confirm that the vehicle has been successfully unlocked through the display or voice, and prompt the user that the vehicle can now be started. The system will continue to monitor the status of the vehicle to ensure that the braking system, vehicle speed, etc. are in a safe state, while monitoring the surrounding environment to ensure that the vehicle is in a safe operating state after starting. The system will then start the vehicle's power system, allowing the user to start using the electric vehicle.

[0055] Embodiment 2: Combination Figures 1 to 4 As shown, the present invention also provides a fingerprint disc brake lock control system, which is controlled by the control method of the fingerprint disc brake lock control system of the first embodiment.
