CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the priority to and the benefit of Chinese Patent Application No. 202110001859.4 filed on Jan. 4, 2021, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present disclosure relates to an automobile authentication technology and, in particular, to a vehicle authentication system based on Bluetooth Low Energy (BLE) and fingerprint. 
     BACKGROUND 
     With development of science and technology and improvement of the standard of living, popularity of vehicles is increasing. As relatively high-value consumer products used as an alternative means of walking, convenience of vehicle use is increasingly attracting attention from people. At present, unlocking and starting of a vehicle is mostly controlled by a vehicle key, and a vehicle user needs to press a relevant button of the vehicle key near the vehicle to realize locking and unlocking. In the same way, the key needs to be inserted into a locking hole and rotated to realize the starting of a vehicle. This traditional way of unlocking and starting greatly weakens the convenience of the vehicle use. 
     In order to improve the convenience of the vehicle use, keyless entry systems and one-key starting systems are increasingly applied to medium-sized and luxury vehicles. Using radio frequency technology and vehicle identification code recognition systems, the vehicle user can realize unlocking and starting functions of the vehicle without any operation on the key. However, these two systems still require the vehicle user to carry the vehicle key, and keyless entry and one-key starting functions cannot be realized if the vehicle user does not carry the key. 
     In recent years, biometric technology has developed rapidly. Since the biometric technology is based on inherent physiological characteristics of a human body for identity authentication, the biometric technology has better security, confidentiality, and convenience, and is widely used in electronic products such as mobile phones, laptops, and tablets. As an advanced recognition technology, there are still many technical problems in applying the biometric technology to a field of vehicles. For example, since the vehicles are often exposed to natural environments such as high temperature, severe cold, wind, and rain, usage environment of the vehicles are more severe than that of electronic products. Therefore, in order to improve the convenience of the vehicle users while ensuring functional reliability, a technical solution that enables locking/unlocking and starting of the vehicle in a variety of ways is required. 
     The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure, and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

     When the AVNT smart interconnection device  110  receives a detection request message from the central control processor  100 , the AVNT smart interconnection device  110  can detect the mobile device  150  within the predetermined range from the vehicle, establish a connection with the detected mobile device  150  through Bluetooth communication to obtain a BLE authentication information of the detected mobile device  150 , and compare the obtained BLE authentication information with a pre-stored BLE authentication information. If the obtained BLE authentication information coincides with the pre-stored BLE authentication information, the AVNT smart interconnection device  110  determines that the mobile device  150  is an authenticated mobile device, and sends the BLE authentication result and a distance information between the authenticated mobile device and the AVNT smart interconnection device to the central control processor  100  in an encrypted manner. 
     If the distance between the authenticated mobile device and the AVNT smart interconnection device is within 3 m the vehicle door can be unlocked, and if the distance between the authenticated mobile device and the AVNT smart interconnection device is 1 m±0.2 m the vehicle can be started. 
     The BLE authentication information of the mobile device  150  is used to identify the detected mobile device, and includes, but is not limited to, an identification code information of the mobile device, a password information sent from the mobile device, a PIN code information sent from the mobile device, and the like. 
     In some forms of the present disclosure, the mobile device  150  may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. Preferably, the mobile device may be a smart phone. 
     In order to ensure a security of the BLE authentication information of the mobile device  150 , the BLE authentication information of the mobile device  150  should be stored securely using an encryption key storing manner and the like. The AVNT smart interconnection device  100  pre-stores the BLE authentication information of the mobile device  150  in a learning manner. 
     The driver-side door handle fingerprint identification device  130  can be mounted on an inner side of a driver-side door handle, detect a fingerprint information of a vehicle user, and send the detected fingerprint information to the fingerprint authentication controller  120  in an encrypted manner. The vehicle starting button fingerprint identification device  140  can be mounted on a starting button in the vehicle, detect the fingerprint information of the vehicle user, and send the detected fingerprint information to the fingerprint authentication controller  120  in an encrypted manner. 
     Both the driver-side door handle fingerprint identification device  130  and the vehicle starting button fingerprint identification device  140  include a fingerprint sensor. If a finger contacts the fingerprint sensor, the fingerprint sensor detects a fingerprint. The fingerprint sensor includes optical fingerprint sensors, semiconductor capacitive sensors, semiconductor thermal detecting sensors, semiconductor pressure sensors, ultrasonic wave sensors, wireless frequency sensors, and the like. 
     The fingerprint authentication controller  120  can be mounted in the vehicle, receive the fingerprint information from the driver-side door handle fingerprint identification device  130  or the fingerprint information from the vehicle starting button fingerprint identification device  140 , compare the received fingerprint information with a pre-stored fingerprint authentication information, and send a fingerprint authentication result to the central control processor  100  in an encrypted manner. 
     The communication between the central control processor  100  and the AVNT smart interconnection device  100  and between the central control processor  100  and the fingerprint authentication controller  120  is performed through CAN (Controller Area Network), but is not limited to the CAN. In addition, encrypted communication manner between the central control processor  100  and the AVNT smart interconnection device  110  may be the same as or different from that between the central control processor  100  and the fingerprint authentication controller  120 . 
     When the central control processor  100  detects a signal of pressing the vehicle driver-side door button or the vehicle starting button, the central control processor  100  send the 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 , the fingerprint authentication controller  120  obtains the fingerprint information from the driver-side door handle fingerprint identification device  130  and the vehicle starting button fingerprint identification device  140 , compares the obtained fingerprint information with the pre-stored fingerprint authentication information, and determines that the obtained fingerprint information is an authenticated fingerprint information if the obtained fingerprint information coincides with the pre-stored fingerprint authentication information. 
     In order to ensure a security of the fingerprint information of the vehicle user, the fingerprint authentication controller  120  should be stored securely using an encryption key storing manner and the like. The fingerprint authentication controller  120  pre-stores the fingerprint information of the vehicle user in a learning manner. 
     The vehicle authentication system in some forms of the present disclosure may further include a passenger-side door handle fingerprint identification device, and the passenger-side door handle fingerprint identification device may be mounted on an inner side of a passenger-side door handle, detect the fingerprint information of the vehicle user, and send the detected fingerprint information to the fingerprint authentication controller  120  in an encrypted manner. The fingerprint authentication controller  120  obtains the fingerprint information from the passenger-side door handle fingerprint identification device, compares the obtained fingerprint information with the pre-stored fingerprint authentication information, and sends the fingerprint authentication result to the central control processor  100  in an encrypted manner. If the central control processor  100  detects a signal of pressing the passenger-side door button of the vehicle, the central control processor  100  sends the detection request message to the fingerprint authentication controller  120 . 
     The vehicle authentication system in some forms of the present disclosure may further include a trunk fingerprint identification device, and the trunk fingerprint identification device may be mounted on the trunk open button, detect the fingerprint information of the vehicle user, and send the detected fingerprint information to the fingerprint authentication controller  120  in an encrypted manner. The fingerprint authentication controller  120  can obtain the fingerprint information from the trunk fingerprint identification device, compare the obtained fingerprint information with the pre-stored fingerprint authentication information, and send the fingerprint authentication result to the central control processor  100  in an encrypted manner. When the central control processor  100  detects a signal of pressing the trunk open button of the vehicle, the central control processor  100  send the detection request message to the fingerprint authentication controller  120 . 
     If necessary, some forms of the present disclosure may further include a fingerprint recognition device, and the fingerprint recognition device may be mounted on, for example, the inner side of the driver-side door handle, the inner side of the passenger-side door handle, the vehicle starting button, the trunk open button, and the like. 
     If the central control processor  100  receives a detection result that the vehicle key exists, the central control processor  100  executes unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key. Here, since detection of the vehicle key is well known to a person skilled in the art, description thereof will be omitted. 
     In addition, if the central control processor  100  receives a detection result that the vehicle key does not exist, the central control processor  100  executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device  110 . 
     In addition, if the central control processor  100  receives the BLE authentication result that the authenticated mobile device does not exist, the central control processor  100  executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller  120 . 
     In addition, the vehicle authentication system in some forms of the present disclosure may further include a warning module, and the warning module may be mounted on an integrated display panel in the vehicle. However, a mounting position of the warning module may not be limited to the integrated display panel in the vehicle and be any other position of the. If none of the vehicle key, the authenticated mobile device, and the authenticated fingerprint information is detected, the warning module displays a logo of “No Fob+BLE+fingerprint”. 
     Since the exemplary form of the present disclosure provides the vehicle authentication system which controls the vehicle unlocking and starting based on the BLE and the fingerprint, the vehicle can be used more conveniently and safely. For example, since the BLE method cannot be used but the fingerprint method can still work normally when the smart phone is out of power and cannot be turned on, the exemplary form of the present disclosure can prevent the vehicle user from being unable to unlock the door and start the vehicle due to no power of the smart phone. Further, fingerprint recognition may be affected by bad weather or an environment with strong electromagnetic radiation. At this time, the BLE method can make up for these deficiencies. 
       FIG. 3  is a flowchart of a vehicle authentication method based on BLE and fingerprint in some forms of the present disclosure. As shown in  FIG. 3 , the central control processor  100  detects whether the signal of pressing the driver-side door button of the vehicle or the vehicle starting button is received at step S 1 , detects whether the vehicle key exists at step S 2  when receiving the signal of pressing the driver-side door button of the vehicle or the vehicle starting button, and sends the detection request message to the AVNT smart interconnection device  110  and the fingerprint authentication controller  120  and checks the detection result of the vehicle key, the BLE authentication result from the AVNT smart interconnection device  110 , and the fingerprint authentication result from the fingerprint authentication controller  120  sequentially in a predetermined priority to control the unlocking the vehicle door or the vehicle starting at step S 3 . 
     Alternatively, the central control processor  100  can detect the signal of the passenger-side door button of the vehicle. Then, when the signal of the passenger-side door button of the vehicle is detected, the central control processor  100  detects whether the vehicle key exists and sends the detection request message to the AVNT smart interconnection device  110  and the fingerprint authentication controller  120 . If receiving the detection result that the vehicle key exists, the central control processor  100  executes the unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key, executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device  110  if receiving the detection result that the vehicle key does not exist, and executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller  120  if receiving the BLE authentication result that the authenticated mobile device does not exist. 
     Alternatively, the central control processor  100  can detect the signal of the trunk open button of the vehicle. Then, when the signal of the trunk open button of the vehicle is detected, the central control processor  100  detects whether the vehicle key exists and sends the detection request message to the AVNT smart interconnection device  110  and the fingerprint authentication controller  120 . If receiving the detection result that the vehicle key exists, the central control processor  100  executes the unlocking the vehicle door or the vehicle starting according to the detection result of the vehicle key, executes the unlocking the vehicle door or the vehicle starting according to the BLE authentication result from the AVNT smart interconnection device  110  if receiving the detection result that the vehicle key does not exist, and executes the unlocking the vehicle door or the vehicle starting according to the fingerprint authentication result from the fingerprint authentication controller  120  if receiving the BLE authentication result that the authenticated mobile device does not exist. 
     If none of the vehicle key, the authenticated mobile device, and the authenticated fingerprint information is detected, the logo of “No Fob+BLE+fingerprint” is displayed. 
     Referring to  FIG. 4 , processes of the vehicle authentication system based on BLE and fingerprint in some forms of the present disclosure will be described by exemplifying the unlocking of the door using the driver-side door button of the vehicle. 
     At step S 401 , the central control processor  100  detects the signal of pressing the driver-side door button of the vehicle. 
     At steps S 402  to S 404 , whether the vehicle key exists is detected, whether the authenticated mobile device exists is detected, and whether the authenticated fingerprint information exists is detected. 
     At step S 403 , whether the authenticated mobile device exists is detected. That is, if the AVNT smart interconnection device  110  receives the detection request message from the central control processor  100 , the AVNT smart interconnection device  110  detects the mobile device  150  within 3 m around the vehicle, establishes the detected mobile device  150  through the Bluetooth communication, and obtains the BLE authentication information of the detected mobile device  150 . Then, the obtained BLE authentication information is compared with the pre-stored BLE authentication information. If the obtained BLE authentication information coincides with the pre-stored BLE authentication information, it is determined that the authenticated mobile device exists, and if the mobile device is not detected within 3 m around the vehicle or the BLE authentication information of the detected mobile device does not coincide with the pre-stored BLE authentication information, it is detected that the authenticated mobile device does not exist. 
     At step S 404 , whether the authenticated fingerprint information exists is detected. That is, if the fingerprint authentication controller  120  receives the detection request message from the central control processor  100 , the fingerprint authentication controller  120  obtains the fingerprint information of the driver-side door handle fingerprint identification device  130 . Then, the obtained fingerprint information is compared with the pre-stored fingerprint authentication information. If the obtained fingerprint information coincides with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is the authenticated fingerprint information. If the obtained fingerprint information does not coincide with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is not the authenticated fingerprint information. 
     At step S 405 , it is determined whether the detection result that the vehicle key exists is received. If the detection result that the vehicle key exists is received, unlocking of the vehicle door is executed according to the detection result of the vehicle key. If the detection result that the vehicle key does not exist, the AVNT smart interconnection device  110  sends the BLE authentication result and the distance information between the authenticated mobile device and the AVNT smart interconnection device  110  to the central control processor  100  in an encrypted manner. 
     At step S 406 , it is determined whether the BLE authentication result that the authenticated mobile device exists is received. If the BLE authentication result that the authenticated mobile device exists is received and the distance between the authenticated mobile device and the AVNT smart interconnection device  110  is within 3 m, the unlocking of the vehicle door can be executed. If the BLE authentication result that the authenticated mobile device does not exist is received, the fingerprint authentication controller  120  sends the fingerprint authentication result to the central control processor  100  in an encrypted manner. 
     At step S 407 , it is determined whether the fingerprint authentication result that the authenticated fingerprint information exists is received. If the fingerprint authentication result that the authenticated fingerprint information exists is received, the unlocking of the vehicle door is executed. If the fingerprint authentication information that the authenticated fingerprint information does not exist is received, the unlocking of the vehicle door is not executed and the warning module displays the logo of “No Fob+BLE+fingerprint”. 
     Referring to  FIG. 5 , processes of the vehicle authentication system based on BLE and fingerprint in some forms of the present disclosure will be described by exemplifying the vehicle starting using the vehicle starting button. 
     At step S 501 , the central control processor  100  receives the signal of pressing the vehicle starting button. 
     At steps S 502  to S 504 , whether the vehicle key exists is detected, whether the authenticated mobile device exists is detected, and whether the authenticated fingerprint information exists is detected. 
     At step S 503 , whether the authenticated mobile device exists is detected. That is, if the AVNT smart interconnection device  110  receives the detection request message from the central control processor  100 , the AVNT smart interconnection device  110  detects the mobile device  150  within 1 m±0.2 m around the vehicle, establishes the detected mobile device  150  through the Bluetooth communication, and obtains the BLE authentication information of the detected mobile device  150 . Then, the obtained BLE authentication information is compared with the pre-stored BLE authentication information. If the obtained BLE authentication information coincides with the pre-stored BLE authentication information, it is determined that the authenticated mobile device exists, and if the mobile device is not detected within 1 m±0.2 m around the vehicle or the BLE authentication information of the detected mobile device does not coincide with the pre-stored BLE authentication information, it is detected that the authenticated mobile device does not exist. 
     At step S 504 , whether the authenticated fingerprint information exists is detected. That is, if the fingerprint authentication controller  120  receives the detection request message from the central control processor  100 , the fingerprint authentication controller  120  obtains the fingerprint information of the vehicle starting button fingerprint identification device  140 . Then, the obtained fingerprint information is compared with the pre-stored fingerprint authentication information. If the obtained fingerprint information coincides with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is the authenticated fingerprint information. If the obtained fingerprint information does not coincide with the pre-stored fingerprint authentication information, it is determined that the obtained fingerprint information is not the authenticated fingerprint information. 
     At step S 505 , it is determined whether the detection result that the vehicle key exists is received. If the detection result that the vehicle key exists is received, the vehicle starting is executed according to the detection result of the vehicle key. If the detection result that the vehicle key does not exist, the AVNT smart interconnection device  110  sends the BLE authentication result and the distance information between the authenticated mobile device and the AVNT smart interconnection device  110  to the central control processor  100  in an encrypted manner. 
     At step S 506 , it is determined whether the BLE authentication result that the authenticated mobile device exists is received. If the BLE authentication result that the authenticated mobile device exists is received and the distance between the authenticated mobile device and the AVNT smart interconnection device  110  is within 1 m±0.2 m, the vehicle starting can be executed. If the BLE authentication result that the authenticated mobile device does not exist is received, the fingerprint authentication controller  120  sends the fingerprint authentication result to the central control processor  100  in an encrypted manner. 
     At step S 507 , it is determined whether the fingerprint authentication result that the authenticated fingerprint information exists is received. If the fingerprint authentication result that the authenticated fingerprint information exists is received, the vehicle starting is executed. If the fingerprint authentication information that the authenticated fingerprint information does not exist is received, the vehicle starting is not executed and the warning module displays the logo of “No Fob+BLE+fingerprint”. 
     In some forms of the present disclosure, since the control method for unlocking the door or starting and unlocking the vehicle using the passenger-side door button and the trunk open button is similar to that for unlocking the door or starting the vehicle using the driver-side door button of the vehicle, detailed description thereof will be omitted.
