[0041] The following will be combined Figure 1-2 , the automobile safety lock control system and method based on fingerprint unlocking involved in the embodiments of the present application are described in detail. It is worth noting that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0042] Example

[0043] Refer to the attached Figure 1 The automobile safety lock control system based on fingerprint unlocking includes: a power supply module, a safety lock system controller, and a door lock fingerprint collection module, an ignition lock fingerprint collection module, a door lock controller, a start controller, a voice feedback module and a central control screen respectively connected to the safety lock system controller.

[0044] Among them, the power supply module is respectively connected to the door lock fingerprint collection module, the ignition lock fingerprint collection module, the safety lock system controller and the door lock controller to provide power to each component.

[0045] The core functions of the security lock system controller include: fingerprint matching to verify user identity; unlocking operations based on matching results; managing fingerprint collection, processing and storage processes; providing voice feedback based on execution status; intelligent power management to save energy; and storing and updating user fingerprint data. In addition, the security lock system controller has anti-interference capabilities to ensure stable operation in various environments.

[0046] The vehicle door lock fingerprint collection module, the safety lock system controller, the vehicle door lock controller and the door lock actuator are connected in sequence to form a vehicle door fingerprint unlocking system; the vehicle door lock fingerprint collection module is installed on the door handle to collect the first fingerprint information to open the vehicle door; when the vehicle door lock fingerprint collection module collects the first fingerprint information, the collected first fingerprint information is sent to the safety lock system controller, and the safety lock system controller compares the received first fingerprint information with the pre-stored fingerprint. If the data are consistent, the safety lock system controller sends a door opening request signal to the vehicle door lock controller, thereby activating the door lock actuator, i.e., the door lock motor, to realize automatic opening of the vehicle door.

[0047] Preferably, the safety lock system controller compares the collected first fingerprint information with the pre-stored fingerprint, and sends a voice broadcast signal to the voice feedback module based on the comparison result, so as to make corresponding voice feedback through the voice feedback module; when the vehicle door is automatically opened, corresponding feedback broadcast can be made, for example: "The door is open, please enter", "Dear user, please get in the car", etc.; if the data is inconsistent, the safety lock system controller sends a voice broadcast signal to the voice feedback module, which can be broadcast according to the relevant personalized voice set in the safety lock system controller, for example: "The current fingerprint does not match, please do not touch", "Do not break in illegally", etc.

[0048] The ignition lock fingerprint collection module, the safety lock system controller and the start controller are connected in sequence to form a cab fingerprint start system; the ignition lock fingerprint collection module is installed at a suitable position on the instrument panel to collect the second fingerprint information to start the vehicle; when the ignition lock fingerprint collection module collects the second fingerprint information, the collected second fingerprint information is sent to the safety lock system controller, and the safety lock system controller compares the received second fingerprint information with the pre-stored fingerprint. If the data is consistent, the safety lock system controller sends a start request signal to the start controller, and the start controller executes the start according to the vehicle start strategy. The vehicle start strategy, for example: the system may only be partially activated when the brakes are not pressed, and it will be fully started when the brakes are pressed. The start strategies are diverse and not limited to the above. At the same time, the safety lock system controller compares the collected second fingerprint information with the pre-stored fingerprint, and sends a voice broadcast signal to the voice feedback module based on the comparison result, so that the voice feedback module can provide corresponding voice feedback;

[0049] The start controller is also connected to other vehicle systems and the central control screen, and the central control screen is connected to the smart networking device and the voice feedback module. The voice feedback module is also connected to the central control screen for other voice feedback and status broadcasts. For example, when the seat belt is not fastened, the voice broadcast is "For your safety, please fasten your seat belt", "Everything is ready and you can go at any time", "The current ignition status is not satisfied, and only some vehicle systems can be activated", etc.

[0050] Fingerprint authorization and related validity periods can be configured and updated through the central control screen and smart connected devices, and the personalized settings of the voice feedback module can also be configured and updated through the central control screen and smart connected devices.

[0051] In a specific embodiment:

[0052] The door lock fingerprint collection module and the ignition lock fingerprint collection module both include: a fingerprint sensor and a communication interface, etc., so as to collect fingerprint information through the fingerprint sensor. The communication interface is used to communicate with the connection line of the safety lock system controller.

[0053] The security lock system controller includes: a communication interface, a fingerprint image processor, a fingerprint template memory, a control logic unit, etc., in order to facilitate connection and realize its functions, that is, the security lock system controller is used to perform fingerprint matching to verify the user's identity, and perform unlocking operations based on the matching results; and manage the fingerprint collection, processing and storage processes; provide voice feedback based on the execution status; intelligent power management to save energy; and store and update user fingerprint data.

[0054] In an optional embodiment, referring to the attached Figure 2 The automobile safety lock control method based on fingerprint unlocking is implemented by a automobile safety lock control system based on fingerprint unlocking, including:

[0055] Fingerprint information entry;

[0056] The input fingerprint information is stored in the safety lock system controller to form a pre-stored fingerprint. The safety lock system controller compares the received first fingerprint information or second fingerprint information with the pre-stored fingerprint to open the door through the first fingerprint information and start the whole vehicle through the second fingerprint information;

[0057] And according to the comparison results, voice broadcast is made.

[0058] Preferably, fingerprint information entry can be achieved through the door lock fingerprint acquisition module or the ignition lock fingerprint acquisition module, and when entering fingerprint information, it must be successfully collected three times before it can be considered as a valid fingerprint information entry. If not, it needs to be collected again. Compared with the current traditional keys, digital keys and NFC keys, there is no loss and possible network virus attacks, which can ensure higher safety of use. After entering the fingerprint, the fingerprint can be quickly identified and the vehicle can be unlocked. Fingerprint unlocking is not affected by the external environment and can unlock the vehicle more efficiently and quickly.

[0059] In addition, the entered fingerprint information needs to be authorized and configured or updated in time; the use rights of the entered fingerprint information can be authorized, and authorization can be performed at different times according to the usage scenario and user, which makes management more convenient.

[0060] The voice announcements can also be personalised.

[0061] The present invention can solve the problem that the current traditional button keys need to be carried around and the button batteries of the traditional button keys need to be replaced in time, which reduces the use of button batteries and is more economical and environmentally friendly. It can also solve the problem that the digital key needs to be carried around and cannot be unlocked when the digital key has no remaining power, the problem that the digital NFC car key needs to be carried around and cannot be unlocked when there is no remaining power, the security problem of the loss of the non-digital NFC car key, the problem that the lock cannot be unlocked normally when the external environment such as light and facial makeup has a great interference with facial recognition, the problem of vehicle use authority for car rental, and the problem of all permissions on the car computer that require password input, so as to avoid the inability to use its functions normally when the password is forgotten.

[0062] The present invention can make the use of vehicles simpler, more environmentally friendly, more economical and more convenient. There is no need to carry traditional car keys, which reduces dependence on traditional car keys and the use of button batteries in traditional car keys, thus reducing costs, saving resources and protecting the environment. The invention is more secure than digital key technology and facial recognition technology. At the same time, the invention can authorize other driver fingerprints, and for the saved fingerprints, the time period of authority can be specified to improve controllability.

[0063] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are only preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
