Description

Technical Field

[0001] This utility model relates to the field of automotive body electronic technology, specifically a novel automotive fingerprint unlocking module. Background Technology

[0002] Conventional keyless entry systems still require a valid key to unlock the vehicle, and if the seats or rearview mirrors have been adjusted by someone else, the conventional method is to access the central control screen and find the user-defined memory button to make the adjustments. This method uses fingerprint recognition, directly linked to personal information. After recognizing the personal information, it simultaneously adjusts the vehicle's seat, rearview mirror, and air conditioning settings.

[0003] To address this, a novel automotive fingerprint unlocking module is proposed. Summary of the Invention

[0021] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1-2 This utility model provides a technical solution:

[0025] A novel automotive fingerprint unlocking module includes a PCB board 3, a fingerprint recognition module 2 mounted on the PCB board 3, a main control MCU mounted on the PCB board 3, and the fingerprint recognition module 2 connected to the main control MCU.

[0026] The main control MCU is connected to the car's central control system, and PCB board 3 has FPC connection lines.

[0027] The fingerprint recognition module 2 includes a fingerprint module, an algorithm MCU, and an SPI FLASH, all of which are connected to the main control MCU.

[0028] For ease of installation, PCB board 3 has positioning holes A4 and B5.

[0029] To facilitate communication, the main control MCU is connected to the body controller via a CAN line, the fingerprint recognition module 2 is connected to the external module, and the fingerprint module, algorithm MCU, and SPI FLASH are connected.

[0030] Working principle:

[0031] Fingerprint information is identified via fingerprint recognition module 2. After fingerprint information is detected, it is compared with the information stored in the system. If the information is deemed valid, it is transmitted to the vehicle controller via the CAN bus. Upon receiving this information, the vehicle controller will unlock the vehicle even if the user does not have the key. If the information is deemed invalid, no action is taken, but an authentication failure message is sent on the bus.

[0032] Furthermore, the fingerprint recognition module 2 can be integrated with other automotive modules to enable personalized customization. For example, after personal information is entered, the vehicle control system simultaneously records the settings for functions such as power seats and rearview mirrors. Even if the settings change, once the fingerprint information is recognized, the vehicle control system will automatically adjust to the previously recorded settings. This function can effectively improve the driver's convenience.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
