[0002] With the advancement of science and technology and the rise in living standards, the ownership rate of vehicles is steadily increasing. As a consumer product with relatively high value as an alternative to walking, the convenience of using automobiles is garnering increasing attention from the public. Currently, unlocking and starting vehicles are mostly controlled by car keys, and users must press the corresponding button on the key while standing near the vehicle to lock or unlock it. For the same reason, the car can only be started by inserting the key into the lock slot and rotating it. These conventional unlocking and starting methods significantly undermine the convenience of vehicle use.

[0003] To enhance the convenience of vehicle use, keyless entry and one-key start systems are increasingly being applied in mid-size and luxury cars. Utilizing radio frequency technology and vehicle identification code recognition systems, users can unlock and start the vehicle without any manipulation of the key. However, these systems still require the user to carry the car key; if the key is not present, keyless entry and one-key start functions cannot be utilized.

[0004] Biometric technology has advanced rapidly in recent years. Since biometric authentication is based on the unique physiological characteristics of the human body, it offers superior security, confidentiality, and convenience. Consequently, it is widely applied in electronic products such as mobile phones and tablet PCs.

Specific details for implementing the invention

[0027] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical methods of the present invention, and detailed implementation methods and specific work processes are presented; however, the scope of protection of the present invention is not limited to the implementation methods described below.

[0028] FIG. 1 illustrates a block diagram of a vehicle authentication system based on BLE and fingerprint methods according to an embodiment of the present invention. The vehicle authentication system according to an embodiment of the present invention includes a central control processor (100), an AVNT (Audio Video Navigation Telecommunication) smart interconnect device (110), a fingerprint authentication controller (120), a driver's door handle fingerprint recognition device (130), a vehicle start button fingerprint recognition device (140), a mobile terminal (150), and a door unlock and vehicle start control system (160).

[0029] When the user's mobile terminal (150) moves close to the vehicle, the user's mobile terminal (150) establishes a communication connection through BLE (Bluetooth Low Energy) technology and the AVNT smart interconnect device (110) inside the vehicle to exchange data, thereby implementing vehicle unlocking and starting functions.

[0030] The door unlocking and vehicle start control system (160) can control the unlocking and start of the door according to the command of the central control processor.

[0031] The AVNT smart interconnect device (100) integrates practical functions such as AI smart language control, remote control, mobile phone real-time interconnect, and GPS navigation. BLE technology is a short-range, low-cost, and interoperable wireless technology that minimizes power consumption by utilizing many intelligent means. The AVNT smart interconnect device (100) controls a Bluetooth module to detect the user's mobile terminal (150) and establishes a wireless connection with the user's mobile terminal (150).

[0032] When the central control processor (100) detects a signal of pressing the driver's door button or the vehicle start button of the vehicle, it can send a request message to the AVNT smart interconnect device (110) to detect whether a mobile terminal (150) exists within the vehicle's set range.

[0033] Alternatively, when the central control processor (100) detects a signal of pressing the passenger door button of the vehicle, it may send a request message to the AVNT smart interconnect device (110) to detect whether a mobile terminal (150) exists within the vehicle's set range.

[0034] Alternatively, when the central control processor (100) detects a signal that the trunk opening button of the vehicle is pressed, it may send a request message to the AVNT smart interconnect device (110) to detect whether a mobile terminal (150) exists within the vehicle's set range.

[0035] In an embodiment of the present invention, the vehicle setting range refers to the distance (D) between the mobile terminal (150) and the AVNT smart interconnect device (100). Referring to FIG. 2, FIG. 2 is a schematic diagram showing the distance range between the mobile terminal (150) and the AVNT smart interconnect device (100). In an embodiment of the present invention, it is detected whether the distance between the mobile terminal (150) and the AVNT smart interconnect device (100) is within area (0) and area (1). Here, the vehicle setting range is within 3m, but the embodiments of the present invention are not limited thereto.

[0036] area Distance between the mobile terminal and the AVNT smart interconnect device Area 0 Generally 1m ± 0.2m (short distance, using vehicle ignition) Area 1 Within 3m (short distance, use for door unlocking) Area 2 12m to 15m (intermediate distance) Area 3 Minimum 300m ± 3m (long distance) Area 4 Over 300m

[0037] When the AVNT smart interconnect device (110) receives a detection request message from the central control processor (100), the AVNT smart interconnect device (110) can detect a mobile terminal (150) within the vehicle's set range and establish a connection with the detected mobile terminal (150) via Bluetooth communication to obtain BLE authentication information of the detected mobile terminal (150) and compare the obtained BLE authentication information with pre-stored BLE authentication information. If the obtained BLE authentication information matches the pre-stored BLE authentication information, the mobile terminal (150) is determined to be an approved mobile terminal, and the BLE authentication result and the distance information between the approved mobile terminal and the AVNT smart interconnect device are sent to the central control processor (100) in an encrypted manner.

[0038] If the distance between the authorized mobile terminal and the AVNT smart interconnect device is within 3m, the door can be unlocked, and if the distance between the authorized mobile terminal and the AVNT smart interconnect device is 1m ± 0.2m, the vehicle can be started.

[0039] The BLE authentication information of the mobile terminal (150) is for recognizing the detected mobile terminal and includes, but is not limited to, identification code information of the mobile terminal, password information sent from the mobile terminal, PIN code information sent from the mobile terminal.

[0040] In an embodiment of the present invention, the mobile terminal (150) is not limited to various personal computers, laptop computers, smartphones, tablet PCs, and portable wearable devices. Preferably, the mobile terminal is a smartphone.

[0041] To ensure the safety of the BLE authentication information of the mobile terminal (150), it must be stored securely using a method such as storing a cryptographic key. The AVNT smart interconnect device (100) stores the BLE authentication information of the mobile terminal (150) in advance through a learning method.

[0042] The driver's door handle fingerprint recognition device (130) is installed on the inner side of the driver's door handle and can collect fingerprint information of the vehicle user and send the collected fingerprint information to the fingerprint authentication controller (120) in an encrypted manner. The vehicle start button fingerprint recognition device (140) is installed on the start button inside the vehicle and can collect fingerprint information of the vehicle user and send the collected fingerprint information to the fingerprint authentication controller (120) in an encrypted manner.

[0043] The driver's door handle fingerprint recognition device (130) and the vehicle start button fingerprint recognition device (140) both include a fingerprint sensor. If a finger comes into contact with the fingerprint sensor, a fingerprint is detected. The fingerprint sensor includes an optical fingerprint sensor, a semiconductor capacitive sensor, a semiconductor thermal sensor, a semiconductor pressure sensor, an ultrasonic sensor, and a radio frequency sensor, etc.

[0044] A fingerprint authentication controller (120) is installed inside a vehicle and receives fingerprint information from a driver's door handle fingerprint recognition device (130) or fingerprint information from a vehicle start button fingerprint recognition device (140), compares the received fingerprint information with pre-stored fingerprint authentication information, and can send the fingerprint authentication result to a central control processor (100) in an encrypted manner.

[0045] Communication between the central control processor (100), the AVNT smart interconnect device (100), and the fingerprint authentication controller (120) is performed via CAN (Controller Area Network), but the communication method is not limited to the CAN communication method. Additionally, the communication encryption method between the central control processor (100), the AVNT smart interconnect device (110), and the fingerprint authentication controller (120) may be the same or different.

[0046] When the central control processor (100) detects a signal that a vehicle driver's door button or a vehicle start button is pressed, it sends a detection request message to the fingerprint authentication controller (120). When the fingerprint authentication controller (120) receives the detection request message from the central control processor (100), it acquires fingerprint information from the driver's door handle fingerprint recognition device (130) and the vehicle start button fingerprint recognition device (140), compares the acquired fingerprint information with pre-stored fingerprint authentication information, and if the acquired fingerprint information matches the pre-stored fingerprint authentication information, it determines the acquired fingerprint information as approved fingerprint information.

[0047] To ensure the safety of the vehicle user's fingerprint information, it must be stored securely using methods such as storing a password key. The fingerprint authentication controller (120) can store the vehicle user's fingerprint information in advance through a learning method.

[0048] Additionally, the vehicle authentication system according to an embodiment of the present invention may further include a passenger door handle fingerprint recognition device, and the passenger door handle fingerprint recognition device may be mounted on the inner side of the passenger door handle and may collect fingerprint information of a vehicle user and send the collected fingerprint information to a fingerprint authentication controller (120) in an encrypted manner. The fingerprint authentication controller (120) acquires fingerprint information from the passenger door handle fingerprint recognition device, compares the acquired fingerprint information with pre-stored fingerprint authentication information, and sends the fingerprint authentication result to a central control processor (100) in an encrypted manner. When the central control processor (100) detects a signal of pressing the passenger door button of the vehicle, it sends a detection request message to the fingerprint authentication controller (120).

[0049] Additionally, the vehicle authentication system according to an embodiment of the present invention may further include a trunk fingerprint recognition device, the trunk fingerprint recognition device may be mounted on a trunk opening button, collect fingerprint information of a vehicle user, and send the collected fingerprint information to a fingerprint authentication controller (120) in an encrypted manner. The fingerprint authentication controller (120) may acquire fingerprint information from the trunk fingerprint recognition device, compare the acquired fingerprint information with pre-stored fingerprint authentication information, and send the fingerprint authentication result to a central control processor (100) in an encrypted manner. When the central control processor (100) detects a signal of pressing the trunk opening button of the vehicle, it sends a detection request message to the fingerprint authentication controller (120).

[0050] In an embodiment of the present invention, a fingerprint recognition device may be installed as needed, and may be mounted, for example, at a location such as the inner side of the driver's door handle, the inner side of the passenger door handle, the vehicle's ignition button, or the trunk opening button.

[0051] When the central control processor (100) receives a detection result indicating the presence of a car key, it performs unlocking the door or starting the vehicle according to the detection result of the car key. Here, since the process for detecting the car key is a known technique in the field, a description of it is omitted in the text.

[0052] Additionally, when the central control processor (100) receives a detection result that the car key does not exist, it unlocks the door or starts the vehicle based on the BLE authentication result from the AVNT smart interconnect device (110).

[0053] Additionally, when the central control processor receives a BLE authentication result indicating that no authorized mobile terminal exists, it performs unlocking the door or starting the vehicle based on the fingerprint authentication result from the fingerprint authentication controller (120).

[0054] Additionally, a vehicle authentication system according to an exemplary embodiment of the present invention further includes an alarm module, said alarm module is installed on an integrated display panel inside the vehicle, but is not limited to the integrated display panel inside the vehicle and may be installed at other locations in the vehicle. If the vehicle key, an authorized mobile terminal, and authorized fingerprint information are all not detected, said alarm module displays a logo of "Fob+BLE+No Fingerprint".

[0055] An exemplary embodiment of the present invention provides a vehicle authentication system that controls the unlocking and starting of a vehicle based on BLE and fingerprint methods, thereby enabling the vehicle to be used more conveniently and safely. For example, if a smartphone cannot be turned on because its battery is dead, the BLE method cannot be used, but the fingerprint method can still operate normally, thus preventing a situation where the vehicle user is unable to unlock the doors or start the vehicle due to the smartphone's dead battery. In addition, the effectiveness of fingerprint recognition may be affected by, for example, bad weather or environments with relatively strong electronic radiation, and in this case, the BLE method can compensate for such defects.

[0056] FIG. 3 is a workflow diagram illustrating a vehicle authentication method based on BLE and fingerprinting according to an embodiment of the present invention. As illustrated in FIG. 3, in step S1, a central control processor (100) detects whether a signal is received for pressing the driver's door button or the vehicle's ignition button; in step S2, when a signal is received for pressing the driver's door button or the vehicle's ignition button, the presence of a car key is detected, and a detection request message is sent to the AVNT smart interconnect device (110) and the fingerprint authentication controller (120); and in step S3, the detection result of the presence of the car key, the BLE authentication result from the AVNT smart interconnect device (110), and the fingerprint authentication result from the fingerprint authentication controller (120) are checked in order according to a predetermined priority, thereby implementing control for unlocking the vehicle door or starting the vehicle.

[0057] Alternatively, the central control processor (100) can detect a signal from the passenger door button of the vehicle, and upon detecting the signal from the passenger door button of the vehicle, detects whether a car key exists and sends a detection request message to the AVNT smart interconnect device (110) and the fingerprint authentication controller (120). Upon receiving a detection result indicating that a car key exists, the door is unlocked or the vehicle is started according to the detection result of the car key; upon receiving a detection result indicating that a car key does not exist, the door is unlocked or the vehicle is started according to the BLE authentication result from the AVNT smart interconnect device (110); and upon receiving a BLE authentication result indicating that an authorized mobile terminal does not exist, the door is unlocked or the vehicle is started according to the fingerprint authentication result from the fingerprint authentication controller (120).

[0058] Alternatively, the central control processor (100) may detect a signal from the trunk opening button of the vehicle, and upon detecting the signal from the trunk opening button of the vehicle, detect whether a car key exists and send a detection request message to the AVNT smart interconnect device (110) and the fingerprint authentication controller (120). Upon receiving a detection result indicating that a car key exists, the door is unlocked or the vehicle is started according to the detection result of the car key; upon receiving a detection result indicating that a car key does not exist, the door is unlocked or the vehicle is started according to the BLE authentication result from the AVNT smart interconnect device (110); and upon receiving a BLE authentication result indicating that an authorized mobile terminal does not exist, the door is unlocked or the vehicle is started according to the fingerprint authentication result from the fingerprint authentication controller (120).

[0059] If the car key, authorized mobile terminal, and authorized fingerprint information are all not detected, the "Fob+BLE+No Fingerprint" logo is displayed.

[0060] Referring to FIG. 4, the operation process of a vehicle authentication system based on BLE and fingerprint methods according to an embodiment of the present invention is described, using the unlocking of a door using the driver's door button of a vehicle as an example.

[0061] In step S401, the central control processor (100) receives a signal to press the driver's door button of the vehicle.

[0062] In steps S402 to S404, the existence of a car key is detected, the existence of an authorized mobile terminal is detected, and the existence of authorized fingerprint information is detected.

[0063] In step S403, the existence of an authorized mobile terminal is detected, that is, when the AVNT smart interconnect device (110) receives a detection request message from the central control processor (100), it detects a mobile terminal (150) within a 3m range around the vehicle, establishes a connection with the detected mobile terminal (150) via Bluetooth communication, obtains BLE authentication information of the detected mobile terminal (150), and compares the obtained BLE authentication information with BLE authentication information stored in advance. If the obtained BLE authentication information matches the BLE authentication information stored in advance, it is determined that an authorized mobile terminal exists, and if no mobile terminal is detected within a 3m range around the vehicle, or if the BLE authentication information of the detected mobile terminal does not match the BLE authentication information stored in advance, it is determined that an authorized mobile terminal does not exist.

[0064] In step S404, the existence of approved fingerprint information is detected. That is, when the fingerprint authentication controller (120) receives a detection request message from the central control processor (100), it acquires fingerprint information from the driver's door handle fingerprint recognition device (130) and compares the acquired fingerprint information with pre-stored fingerprint authentication information. If the acquired fingerprint information matches the pre-stored fingerprint authentication information, the acquired fingerprint information is determined to be approved fingerprint information. If the acquired fingerprint information does not match the pre-stored fingerprint authentication information, the acquired fingerprint information is determined not to be approved fingerprint information.

[0065] In step S405, it is determined whether a detection result indicating the existence of a car key has been received. If a detection result indicating the existence of a car key is received, the door is unlocked according to the detection result of the car key. If a detection result indicating that a car key has not been received is received, the AVNT smart interconnect device (110) sends the BLE authentication result and the distance information between the authorized mobile terminal and the AVNT smart interconnect device (110) to the central control processor (100) in an encrypted manner.

[0066] In step S406, it is determined whether a BLE authentication result indicating the existence of an authorized mobile terminal is received. If a BLE authentication result indicating the existence of an authorized mobile terminal is received and the distance between the authorized mobile terminal and the AVNT smart interconnect device (110) is within 3m, the door can be unlocked. If a BLE authentication result indicating that no authorized mobile terminal is received is received, the fingerprint authentication controller (120) sends the fingerprint authentication result to the central control processor (100) in an encrypted manner.

[0067] In step S407, it is determined whether a fingerprint authentication result indicating the existence of authorized fingerprint information has been received. If a fingerprint authentication result indicating the existence of authorized fingerprint information is received, the door is unlocked. If fingerprint authentication information indicating the absence of authorized fingerprint information is received, the door is not unlocked, and the alarm module displays the "Fob+BLE+No Fingerprint" logo.

[0068] Referring to FIG. 5, the operation process of a vehicle authentication system based on BLE and fingerprint methods according to an embodiment of the present invention is described, using vehicle ignition using a vehicle ignition button as an example.

[0069] In step S501, the central control processor (100) receives a signal to press the vehicle's start button.

[0070] In steps S502 to S504, the existence of a car key is detected, the existence of an authorized mobile terminal is detected, and the existence of authorized fingerprint information is detected.

[0071] In step S503, the existence of an authorized mobile terminal is detected. That is, when the AVNT smart interconnect device (110) receives a detection request message from the central control processor (100), it detects a mobile terminal (150) within a range of 1m ± 0.2m around the vehicle, establishes a connection with the detected mobile terminal (150) via Bluetooth communication, obtains BLE authentication information of the detected mobile terminal (150), and compares the obtained BLE authentication information with BLE authentication information stored in advance. If the obtained BLE authentication information matches the BLE authentication information stored in advance, it is determined that an authorized mobile terminal exists. If no mobile terminal is detected within a range of 1m ± 0.2m around the vehicle, or if the BLE authentication information of the detected mobile terminal does not match the BLE authentication information stored in advance, it is determined that an authorized mobile terminal does not exist.

[0072] In step S504, the existence of approved fingerprint information is detected. That is, when the fingerprint authentication controller (120) receives a detection request message from the central control processor (100), it acquires fingerprint information from the vehicle start button fingerprint recognition device (140) and compares the acquired fingerprint information with pre-stored fingerprint authentication information. If the acquired fingerprint information matches the pre-stored fingerprint authentication information, the acquired fingerprint information is determined to be approved fingerprint information. If the acquired fingerprint information does not match the pre-stored fingerprint authentication information, the acquired fingerprint information is determined not to be approved fingerprint information.

[0073] In step S505, it is determined whether a detection result indicating the existence of a car key has been received. If a detection result indicating the existence of a car key is received, the vehicle is started according to the detection result of the car key. If a detection result indicating that a car key has not been received is received, the AVNT smart interconnect device (110) sends the BLE authentication result and the distance information between the authorized mobile terminal and the AVNT smart interconnect device (110) to the central control processor (100) in an encrypted manner.

[0074] In step S506, it is determined whether a BLE authentication result indicating the existence of an authorized mobile terminal is received. If a BLE authentication result indicating the existence of an authorized mobile terminal is received and the distance between the authorized mobile terminal and the AVNT smart interconnect device (110) is within 1m ± 0.2m, the vehicle can be started. If a BLE authentication result indicating that no authorized mobile terminal is received is received, the fingerprint authentication controller (120) sends the fingerprint authentication result to the central control processor (100) in an encrypted manner.

[0075] In step S507, it is determined whether a fingerprint authentication result indicating the existence of authorized fingerprint information has been received. If a fingerprint authentication result indicating the existence of authorized fingerprint information is received, the vehicle is started.
